User Guide

Natron is an open source video compositing and special effects software for Windows, macOS and Linux.

This guide will help you getting started using Natron for compositing and visual effects.

What is compositing?

Compositing is the combining of visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene [Wikipedia].

Typical examples of compositing are, for example:

  • The superimposition of a character filmed on a green background over a scene shot in another place, at another time, or a computer-generated scene;
  • The manual detouring (also called rotoscopy) of an element in a video to embed it in another video, possibly with a different motion;
  • Artistic modifications of a video, after shooting a live-action scene or rendering a CGI scene, in order to modify its lighting, colors, depth of field, camera motion, or to remove noise or add film grain.

A video compositing software is not a 3D computer graphics software, like Blender or Maya, but it is perfectly suited for combining computer-generated elements produced by other software with live-action video or 2D animation. Rather than rendering a full 3D scene with the 3D software, which may cost many hours of computation, the video compositing software can assemble the elements produced separately with a much more reactive interface and an almost instantaneous visual feedback.

Theory

The math behind compositing was formalized by Porter & Duff [PorterDuff1984] after the preliminary work by Wallace [Wallace1981]. More informating about the theory behind compositing can be found in the works of Jim Blinn [Blinn1994a] [Blinn1994b] and Alvy Ray Smith [Smith1995].

The compositing theory also introduces the notion of “premultipled” RGB values, or “associated alpha”, and there is still a lot of debate about premultiplying or not.

Natron made the choice of using premultiplied alpha by default in the compositing workflow, like all modern compositing software, because images are stored internally with floating-point values.

Practice

There are excellent books that introduce how to do compositing in practice, and using compositing software: [Wright2010], [Brinkmann2008], [Lanier2009], [VES2014].

Most of what is described in these books also apply to Natron. It is thus strongly recommended to become familiar with the techniques and workflows described in these books before starting to use Natron.

There are also video tutorials available on video streaming platforms (youtube, vimeo) for Natron or other reference compositing software, such as Nuke of Fusion. These tutorials can be used to get acquainted with compositing.

FAQ
Can I use Natron for commercial work?

Yes. Anything you create with Natron is yours and you’re free to do anything you want with it.

What operating systems are supported by Natron?

Natron officially supports:

  • Windows 7, 8 and 10 with latest service packs.
  • MacOSX 10.6 or greater
  • Linux 2.6.18 or greater (Glibc 2.12+/libgcc 4.4+)
Why did you make Natron free of charge?

Our original motives were to create a tool for people who needed it and that may felt left-aside by the software editor’s pricing plans. These users include but are not limited to:

  • Students who want to learn compositing at home
  • Schools that may not be able to buy expensive software licenses

Another reason why Natron was developed mainly at INRIA is because a compositing software is a playground that enables scientists in computer vision/graphics to develop, test exchange and publish results easily on such platform.

One great mission of an free open-source software is to create common practices so everyone can benefit from it.

On the other hand, being free of charge, Natron can be installed on large-scale render farms without wondering about licensing issues.

What is OpenFX?

OpenFX is a standard for creating visual effects plug-ins for compositing and editor applications.

As of today several applications are compatible with this plug-in format: (meaning you can use the same plug-ins in all of them)

  • Nuke 5.1+, by The Foundry
  • Vegas 10+, by Sony
  • SCRATCH 6.1+, by Assimilate
  • Fusion 5.1+, by Blackmagic Design (formerly by eyeon)
  • DaVinci Resolve 10+, by Blackmagic Design
  • DustBuster+ 4.5+, by HS-ART
  • Baselight 2.2+ by FilmLight
  • Nucoda Film Master 2011.2.058+
  • SGO Mistika 6.5.35+
  • Autodesk Toxik 2009+
  • Avid DS 10.3+
  • Natron
  • ButtleOFX
  • TuttleOFX
Can I use commercial and proprietary plug-ins within Natron?

Yes. Natron doesn’t limit you to open-source plug-ins.

Is my graphics card supported?

An OpenGL 2.0 compatible graphics card is needed to run Natron (2.1+) with hardware-accelerated rendering. Other graphics cards work with software-only rendering (see below).

The following graphics cards are supported for hardware-accelerated rendering:

  • Intel GMA 3150 (Linux-only)
  • Intel GMA X3xxx (Linux-only)
  • Intel GMA X4xxx (Windows 7 & Linux)
  • Intel HD (Ironlake) (Windows 7 & Linux)
  • Intel HD 2000/3000 (Sandy Bridge) (Windows 7/Linux/Mac)
  • Intel HD 4000 and greater (All platforms)
  • Nvidia GeForce 6 series and greater
  • Nvidia Quadro FX and greater
  • Nvidia Quadro NVS 285 and greater
  • ATI/AMD Radeon R300 and greater
  • ATI/AMD FireGL T2-64 and greater (FirePro)

Cards not listed here will probably not support hardware-accelerated rendering.

It is possible to enable software rendering using the following techniques.

*On Linux, enable the environment variable LIBGL_ALWAYS_SOFTWARE=1 before running Natron.

*On Windows, enable the legacy hardware package in the Natron installer.

Run

On OS X 10.7 and later, you may get the message “Natron has not been signed by a recognized distributor and may damage your computer. You should move it to the trash”.

The macOS binaries are not signed with an Apple Developer ID, because of incompatibilities between the Apple code signing tools and the compiler (GCC 4.9) and target OS (Mac OS X 10.6) we use.

There are at least four options to launch Natron on macOS:

  • rather than double-clicking on the Natron application, right-click or control-click on it and select Open
  • after an unsuccessful launch of Natron, go to the Security & Privacy preferences panel, and enable it.
  • from the terminal command-line, execute spctl --add /Applications/Natron.app, as explained in this OSXDaily article.
  • (not recommended) click “Allow apps downloaded from: Anywhere” in the Security & Privacy preferences panel. Since macOS 10.12 Sierra, this option is not available anymore, but it is possible to re-enable it, as explained in that OSXDaily article.

Troubleshooting

Natron has bugs, as any software does.

Natron is also a free and open-source software, and bugs are fixed by volunteers when they have some spare time, so please be tolerant and do not expect your bug to be fixed within the hour. It may take days, weeks, or it may even never be fixed.

Properly reporting a bug takes time, but the time spent reporting a bug will certainly help you and the community a lot. It is also the best way to find a temporary solution or a workaround.

Identifying the Kind of Bug

Natron may fail in several ways:

  1. It crashes while doing some specific user interaction with the GUI.
  2. It crashes while rendering the project.
  3. Rendered images are wrong, or contain black areas.
  4. Natron hangs and the GUI is not responsive (i.e. menus and buttons do not respond). This is probably a deadlock in the GUI code of Natron.
  5. Rendering stops before the end of the sequence. This is probably caused by an OpenFX error: check the error log from the “Display/Show Project Errors Log…” menu: there may be an indication of the problem (but it can still be a Natron bug).
  6. Rendering hangs or Natron hangs, but the GUI is responsive. This is probably a deadlock in the rendering code, and this is the hardest kind of bug to reproduce or fix. If it cannot be reproduced easily, then your best bet is to use one of the workarounds below.
Searching and Reporting Bugs

Bugs may come from OpenFX plugins that were not bundled with Natron, so before reporting anything, if you have any extra OpenFX plugins installed, uncheck “Enable default OpenFX plugins location” in “Preferences/Plug-ins”, save preferences, relaunch Natron, and check that the bug is still here.

The best way to have your bug considered for fixing is to first search on the Natron forum and in the Natron issues if this is a known bug. If yes, then read about it, and try some workarounds given in these bug reports (see below for more workarounds).

If this bug does not seem to be a known issue, then post a new issue on the Natron github, and follow strictly the guidelines to report the bug. The issue title should be as precise as possible (“Natron crash” is not a correct title, see existing issues for title examples). If possible, also post a project that exhibits the issue. Make the project as small as possible: remove extra assets or replace them by small JPEG sequences, checkerboards or colorwheels, etc. You can then either attach your project as a zip file to the github issue, or post a link to a file sharing service.

Common Workarounds

Luckily, there are workarounds for most Natron crashes or hangs. Here are a few one worth trying, but of course your mileage may vary or you may find another workaround (which you should describe in the proper Natron issue).

  1. Avoid using videos with inter-frame compression as inputs and outputs. This includes H.264 (eg AVCHD) and H.265 (HEVC) video. ProRes is OK but slow, especially for writing. DNxHR is OK. Individual frames are best (DPX, EXR, TIFF, PNG, JPEG, whatever suits your input video quality and bit depth). The video reader is here for convenience, but it may have difficulties decoding some videos. The video writer may also be a source of bugs, and should be avoided for long sequences: if Natron crashes in the middle, then the whole sequence has to be rendered. Extract individual frames, do your compositing, then compress the frames (and optionally mux the audio) with an external tool. To extract frames, you may use a simple Natron project or any other tool (e.g. FFmpeg). To compress frames to a video, there are also many tools available, e.g. FFmpeg, MEncoder, or VirtualDub (windows-only). This is the standard compositing workflow and the preferred method of running Natron.
  2. If Natron hangs or crashes when rendering an image sequence (this does not work when rendering to a video), check that the rendered frames are OK, relaunch Natron and in the parameters of the Write node uncheck “Overwrite”. That way, only the missing frames will be rendered.
  3. If you have a large project, or a project with heavy processing, use the DiskCache Plugin at places that make sense: downstream heavy processing in the graph, or before you use the result of processing as inputs to Roto or RotoPaint.

You will quickly notice that using individual frames instead of videos for inputs and output give a big performance boost and will most probably solve your issues, so once you’ve learned how to decompress/compress any video, this will become your standard workflow. Just add extra disk space, and you’re good to do serious and fluid compositing with Natron.

OpenGL/GPU Rendering Issues

If the viewer displays some error message about OpenGL, then GPU rendering is probably going bad. Note that this kind of problem seems to only happen on Windows, so you might want to consider switching to Linux or macOS to use Natron if your GPU is not well supported by Natron under Windows.

  1. Create a Shadertoy, click “Renderer Info…” and check that the OpenGL version is at least 2.1 and that the extension GL_ARB_texture_non_power_of_two is available. If the displayed info does not correspond to your graphics card, check that the OpenGL drivers for your card are installed. If not, install the software called “OpenGL Extension Viewer” and check that your card appears in the list of renderers. If not, then it is a drivers issue.
  2. In Natron Preferences / GPU Rendering, check that the displayed is consistent with what “Renderer Info…” above gave.
  3. Now uncheck “Enable GPU Render” in the Shadertoy node and click the refresh/recycle button on the top of the viewer. Click again “Renderer Info…” and it should say it now uses Mesa in the GL_VERSION. Does it fix the issue? If yes, you may try the next step to globally disable OpenGL rendering in Natron.
  4. To temporarily fix this issue, in Natron Preferences / GPU Rendering, set “OpenGL Rendering” to “Disabled”, click the “Save” button in the Preferences window, quit Natron, launch Natron, check that GPU rendering is still disabled in the Preferences, and test your project.

Frame ranges

The project frame range (in the Project Settings, key ‘s’ in the Node Graph’) is the range that will be used by default when rendering Writers.

Each clip (input or output of a node in the Node graph) also has its own frame range. This “clip frame range” may be used or even modified by plugins, such as Retime (which may change the frame range), Merge or Switch (which set the frame range to the union of their input frame ranges). The plugin may be able to render images outside of this frame range, and it is just an indication of a valid frame range. This information is available from the “Info” tab of the properties panel of each node.

Most generator plugins (e.g. CheckerBoard, ColorBars, ColorWheel, Constant, Solid) have a “Frame Range” parameter, which is (1,1) by default. The FrameRange plugin may be used to modify this frame range inside the graph.

The default framerange of an image sequence or video is the range of the sequence

Tracking and stabilizing

Workflow Summary

In order to track a planar shape and move a Roto mask or a texture corresponding to that shape:

  • Track some points inside your mask (shape)
  • In the Transform tab, set the transform to CornerPin and to match-move
  • Disable the CornerPin and set the from points of the corner pin at the reference frame where you want your object to move in (basically the bounding box of the shape to track)
  • Export to CornerPin
  • Append your CornerPin to the Roto node

In a future version we will have a planar tracker that will do that automatically for you in a single click.

Detailed Usage

To link parameters in Natron, it is the same as in Nuke except that you drag and drop the widget of a parameter onto another one by holding the control key (or cmd on macOS).

The tracker works differently than the Nuke tracker regarding the “Transform” part. For the tracking itself, almost everything is the same. Basically, in Nuke they can only output a CornerPin with exactly 4 points, and they map 1 track to each corner of the CornerPin. For the Transform node they may use 1 (translation only), 2, or N points to find the final transformation, however that will never be something other than a similarity, which means that it cannot handle perspective deformation.

In Natron, we offer the possibility to compute a CornerPin with N points, that is an homography, which encompasses all distortion-free perspective transforms.

This is much better, because the more tracks you use to compute that CornerPin, the more robust it will be.

An homography is typically used to contain information about a perspective deformation, whereas a similarity is more constrained: a similarity is translation, rotation and uniform scale.

In The Transform tab, this is what we call “the model”. Basically, the problem we are trying to solve is to fit a model (i.e. similarity or homography) so it is the closest to the N point correspondences. Each correspondence is the position of a track at the reference frame and its position at the tracked time.

Hence the more correspondences you have (i.e. the more tracks), the more robust the homography is in the region where you tracked features.

The Fitting error parameter (in the Transform tab) is an indication of how much difference there is in pixels between the reference point on which we applied the computed transformation and the original tracked point. This is the RMS (root mean square) error across all tracks, and gives an estimate of the quality of the model found in pixel units.

For each tracked frame, the correspondences we use to compute the CornerPin are the tracks that are enabled at this frame (i.e. the Enabled parameter is checked at this time) and that have a keyframe on the center (i.e. they successfully tracked).

When you press Compute, it computes the model (CornerPin/Transform) with all the tracks that meet the aforementioned requirements over all keyframes.

When Compute Transform Automatically is checked, whenever a parameter that has an effect on the output model is changed, this will recompute the Corner/Pin transform over all keyframes again.

The parameters that have an effect on the output model are:

  • The motion type
  • The Transform Type (i.e. Similarity or Homography)
  • The Reference Frame
  • Jitter Period
  • Smooth: this can be used to smooth the resulting curve to remove some of the noise in the high frequencies of the CornerPin/Transform. Note that in “Add Jitter” mode, you can increase High frequencies to simulate a camera shake that follows the original camera movements.
  • Robust model: this is quite complicated, but in short: When trying to find a model that best fits all correspondences, you may have correspondences that are just wrong (bad tracking for example). These bad correspondences are called outliers, and this parameter when checked tells we should not take into account those outliers to compute the final model. In most cases this should be checked. However sometimes, the user may have for example required to compute an homography (i.e. CornerPin), but the given tracked points (correspondences) just cannot make-up an homography. In this case, if the parameter were to be checked, it would fail to compute a model. If you uncheck this, it will take into account all the points and compute a model that averages the motion of all correspondences.

Also when Compute Transform Automatically is checked, the model will be computed automatically when the tracking ends.

We cannot compute the model after each track step (i.e. during tracking) because the model at each frame depends on the model at other frames since we may smooth the curve or add jitter.

So all in all it works differently than Nuke, the whole transformation computation can be more robust and happens as a second pass after the tracking is actually done.

One last thing: to compute the CornerPin in the “Transform” tab of the tracker, the to points are computed using the from points as reference.

Basically what happens is that the tracking outputs a transformation matrix at each frame. Then when computing the model, this matrix is applied to the from points at each frame in order to obtain the to points.

So if you were to change the reference points (i.e. the from points) with the Set to input RoD for example, then you would need to recompute the model at all frames, because the to points would just not be the same.

The work is usually done in two steps:

  • First, disable the CornerPin so that even if the viewer is connected to the Tracker there is no deformation going on, and set the from points to be the RoD (bounding box) of the Roto shape at the reference frame.
  • Then, export the CornerPin. It just links the parameters of the CornerPin to the ones in the tracker, so if you change something in the tracker transform tab the changes will reflect onto the CornerPin.

Basically what the Planar tracker will do in the future is automatically do all the steps for you: it will place markers inside the mask for you, track them and output a CornerPin from the bounding box of the roto shape.

Stereoscopic compositing

Importing stereoscopic sequences

When creating a new project in Natron, by default there is a single view present. It is called the “Main” view.

_images/multiview01.png

You can add, remove and rename views as desired. Clicking the “Setup views for stereo” button will make exactly 2 views named “Left” and “Right”.

Upon importing an EXR file containing multiple views within the file, Natron will prompt you to create the appropriate views in the project:

_images/multiview02.png

If clicking yes, Natron will create the missing views in the project:

_images/multiview08.png

You can remove the “Main” view if needed (in our case it does not make sense to leave it in the project). You can do so by clicking either Remove and selecting the “Main” view or clicking “Setup views for stereo”:

_images/multiview09.png

The Read node will have a special “V” mark on its top-left corner, indicating that it has multiple views available. When hovering the “V” indicator with the mouse, more information is available regarding which views are present in this Read node

_images/multiview10.png

Hovering your mouse over the Output Layer parameter will detail which layer is available in which view:

_images/multiview11.png

When the project has multiple views available, each viewer will have a drop-down with available views. You can select with view to display:

_images/multiview03.png

If we take a look at our Read node’s properties, you can see that we have 2 layers in this file: RGBA and depth. Layers may sometimes not be present in all views in the file, but the Read node will show the union of all layers available across all views:

_images/multiview04.png
Joining separate views

In Natron you can join different simple-view files to a multiple-view stream by using the JoinViews node, like this:

_images/multiview12.png
Exporting stereoscopic sequences

Exporting multi-view files in Natron can be done multiple ways: Either you want to have a separate file for each view, or you want all views to be in the same file. The later is only supported by the EXR file format. When exporting to EXR, the Write node properties panel will have an extra “Views” parameter:

_images/multiview05.png

This is quite straight-forward: you can select which views you decide to export.

You can also select which layer you would like to export:

_images/multiview06.png

The “All” choice is only available for the EXR and TIFF file formats which allow embedding more than 1 layer per-file.

Another interesting parameter controls how the EXR/TIFF file is written, this is the “Parts” parameter:

_images/multiview07.png

When set to “Single Part”, the Write node will aggregate all views requested to render in a single “part” of the file. Single part files are what is written by OpenEXR 1.x applications, thus selecting “Single Part” ensures compatibility with other applications that do not support OpenEXR 2.

When set to “Split Views”, all views will be scattered in different parts of the file. The resulting file will only be readable in applications that support OpenEXR 2 but with the advantage of being faster to read than the single-part files. Note that if you select “All” layers to render all layers will be aggregated for each view.

When set to “Split Views,Layers” each layer of each view will be written to a separate part, ensuring EXR optimized for decoding speed, though the file will be larger.

Writing to separate files

You can choose to export views to a separate files by adding a %v (which will expand to the letter ‘l’ or ‘r’) or %V (which will expand to the word “left” or “right”) to the output filename:

_images/multiview13.png

In that case the “Views” parameter will no longer be available. This is how you should proceed if you want to output multiple views but do not want to write EXR’s.

By default for files that do not support multi-view (I.e: anything besides EXR), if requesting to write multiple views to the same file, Natron will only write the first view in the project’s views. If you do not want to render all views but a specific one, you can use a “OneView” node prior to your Write node to specify which view you would like to write-out:

_images/multiview14.png

Preview and rendering (empty)

Expressions (empty)

The value of any Node parameter can be set by Python expression. An expression is a line of code that can either reference the value of other parameters or apply mathematical functions to the current value.

Natron supports 2 types of expression languages:

Basic Expression are very fast and simple and should cover 99% of the needs for expressions. By default this is the language proposed to you when editing an expression.

Python based expressions are using the same A.P.I as everything else using Python in Natron. It allows to write really any kind of expression referencing external functions and data, however it is much slower to evaluate and will impair performance compared to a basic expression.

Where possible, you should use basic expressions, unless you specifically need a feature available in the Python API that is not available through the basic expressions language.

For more informations on developping Python expression, please refer to this section.

The rest of this section will cover writing basic expressions.

String Processing

FUNCTION DEFINITION
= , == !=, <> <=, >= < , > All common equality/inequality operators are applicable to strings and are applied in a case sensitive manner. In the following example x, y and z are of type string. (eg: not((x <= ‘AbC’) and (‘1x2y3z’ <> y)) or (z == x)
in True only if x is a substring of y. (eg: x in y or ‘abc’ in ‘abcdefgh’)
like True only if the string x matches the pattern y. Available wildcard characters are ‘*’ and ‘?’ denoting zero or more and zero or one matches respectively. (eg: x like y or ‘abcdefgh’ like ‘a?d*h’)
ilike True only if the string x matches the pattern y in a case insensitive manner. Available wildcard characters are ‘*’ and ‘?’ denoting zero or more and zero or one matches respectively. (eg: x ilike y or ‘a1B2c3D4e5F6g7H’ ilike ‘a?d*h’)
[r0:r1]

The closed interval [r0,r1] of the specified string. eg: Given a string x with a value of ‘abcdefgh’ then: 1. x[1:4] == ‘bcde’ 2. x[ :5] == x[:5] == ‘abcdef’ 3. x[3: ] == x[3:] ==’cdefgh’ 4. x[ : ] == x[:] == ‘abcdefgh’ 5. x[4/2:3+2] == x[2:5] == ‘cdef’

Note: Both r0 and r1 are assumed to be integers, where r0 <= r1. They may also be the result of an expression, in the event they have fractional components truncation will be performed. (eg: 1.67 –> 1)

:=

Assign the value of x to y. Where y is a mutable string or string range and x is either a string or a string range. eg: 1. y := x 2. y := ‘abc’ 3. y := x[:i + j] 4. y := ‘0123456789’[2:7] 5. y := ‘0123456789’[2i + 1:7] 6. y := (x := ‘0123456789’[2:7]) 7. y[i:j] := x 8. y[i:j] := (x + ‘abcdefg’[8 / 4:5])[m:n]

Note: For options 7 and 8 the shorter of the two ranges will denote the number characters that are to be copied.

+ Concatenation of x and y. Where x and y are strings or string ranges. eg 1. x + y 2. x + ‘abc’ 3. x + y[:i + j] 4. x[i:j] + y[2:3] + ‘0123456789’[2:7] 5. ‘abc’ + x + y 6. ‘abc’ + ‘1234567’ 7. (x + ‘a1B2c3D4’ + y)[i:2j]
+= Append to x the value of y. Where x is a mutable string and y is either a string or a string range. eg: 1. x += y 2. x += ‘abc’ 3. x += y[:i + j] + ‘abc’ 4. x += ‘0123456789’[2:7]
<=> Swap the values of x and y. Where x and y are mutable strings. (eg: x <=> y)
[] The string size operator returns the size of the string being actioned. eg: 1. ‘abc’[] == 3 2. var max_str_length := max(s0[],s1[],s2[],s3[]) 3. (‘abc’ + ‘xyz’)[] == 6 4. ((‘abc’ + ‘xyz’)[1:4])[] == 4

Control Structures

STRUCTURE DEFINITION
if If x is true then return y else return z. eg: 1. if (x, y, z) 2. if ((x + 1) > 2y, z + 1, w / v) 3. if (x > y) z; 4. if (x <= 2*y) { z + w };
if-else

The if-else/else-if statement. Subject to the condition branch the statement will return either the value of the consequent or the alternative branch. eg: 1. if (x > y) z; else w; 2. if (x > y) z; else if (w != u) v; 3. if (x < y) {z; w + 1;} else u; 4. if ((x != y) and (z > w))

{
y := sin(x) / u; z := w + 1;

} else if (x > (z + 1)) {

w := abs (x - y) + z; u := (x + 1) > 2y ? 2u : 3u;

}

switch

The first true case condition that is encountered will determine the result of the switch. If none of the case conditions hold true, the default action is assumed as the final return value. This is sometimes also known as a multi-way branch mechanism. eg: switch {

case x > (y + z) : 2 * x / abs(y - z); case x < 3 : sin(x + y); default : 1 + x;

}

while

The structure will repeatedly evaluate the internal statement(s) ‘while’ the condition is true. The final statement in the final iteration will be used as the return value of the loop. eg: while ((x -= 1) > 0) {

y := x + z; w := u + y;

}

repeat/ until

The structure will repeatedly evaluate the internal statement(s) ‘until’ the condition is true. The final statement in the final iteration will be used as the return value of the loop. eg: repeat

y := x + z; w := u + y;

until ((x += 1) > 100)

for

The structure will repeatedly evaluate the internal statement(s) while the condition is true. On each loop iteration, an ‘incrementing’ expression is evaluated. The conditional is mandatory whereas the initialiser and incrementing expressions are optional. eg: for (var x := 0; (x < n) and (x != y); x += 1) {

y := y + x / 2 - z; w := u + y;

}

break break[]

Break terminates the execution of the nearest enclosed loop, allowing for the execution to continue on external to the loop. The default break statement will set the return value of the loop to NaN, where as the return based form will set the value to that of the break expression. eg: while ((i += 1) < 10) {

if (i < 5)
j -= i + 2;
else if (i % 2 == 0)
break;
else
break[2i + 3];

}

continue

Continue results in the remaining portion of the nearest enclosing loop body to be skipped. eg: for (var i := 0; i < 10; i += 1) {

if (i < 5)
continue;

j -= i + 2;

}

return

Return immediately from within the current expression. With the option of passing back a variable number of values (scalar, vector or string). eg: 1. return [1]; 2. return [x, ‘abx’]; 3. return [x, x + y,’abx’]; 4. return []; 5. if (x < y)

return [x, x - y, ‘result-set1’, 123.456];
else
return [y, x + y, ‘result-set2’];
?: Ternary conditional statement, similar to that of the above denoted if-statement. eg: 1. x ? y : z 2. x + 1 > 2y ? z + 1 : (w / v) 3. min(x,y) > z ? (x < y + 1) ? x : y : (w * v)
~ Evaluate each sub-expression, then return as the result the value of the last sub-expression. This is sometimes known as multiple sequence point evaluation. eg: ~(i := x + 1, j := y / z, k := sin(w/u)) == (sin(w/u))) ~{i := x + 1; j := y / z; k := sin(w/u)} == (sin(w/u)))
[*]

Evaluate any consequent for which its case statement is true. The return value will be either zero or the result of the last consequent to have been evaluated. eg: [*] {

case (x + 1) > (y - 2) : x := z / 2 + sin(y / pi); case (x + 2) < abs(y + 3) : w / 4 + min(5y,9); case (x + 3) == (y * 4) : y := abs(z / 6) + 7y;

}

[] The vector size operator returns the size of the vector being actioned. eg: 1. v[] 2. max_size := max(v0[],v1[],v2[],v3[])

To get more details on the language syntax and available mathematical functions, this is fully covered by the README.

Additional variables and functions are made available by Natron to access values of other parameters and effects.

Parameters

Parameters value can be referenced by their script-name. See this section to learn how to determine the script-name of a node. See this section to learn how to determine the script-name of a parameter.

For instance:

# This is the value in the x dimension of the size parameter of the Blur1 node
Blur1.size.x

# The operator parameter is a 1-dimensional Choice parameter, there's no dimension
# suffix
Merge1.operator

Note that parameters on the node on which the expression is actually set can be referenced without prefixing the script-name of the node:

# Assuming we are writing an expression on the node Blur1,
# its parameter size can be accessed directly
size.y

In the same way, values of dimensions can be accessed directly using the special variable thisParam:

# Assuming we are writing an expression for Merge1.operator
thisParam

# Assuming we are writing an expression for Blur1.size.y
thisParam.x

Warning

Returning the value of the parameter dimension for which the expression is being evaluated will not cause an infinite recursion but instead will return the value of the parameter without evaluating the expression.

Dimension names (x,y,r,g,b, w,h , etc…) are merely corresponding to a 0-based index, and can be interchanged, e.g:

# Referencing dimension 0 of the parameter size
size.r

# Referencing dimension 1 of the parameter size
size.g

# Referencing dimension 0 of the parameter size
size.x

# Referencing dimension 0 of the parameter size
size.0

# Referencing dimension 1 of the parameter size
size.1

This allows to write easier expressions when referencing other parameters that do not have the same dimensions.

Possible variants to reference a dimension is as follow:

  • r,g,b,a
  • x,y,z,w
  • 0,1,2,3

The dimension of the parameter on which the expression is currently executed can be referenced with dimension:

# Assuming we are writing an expression for size.y
# We return the value of the masterSaturation parameter of the ColorCorrect1 node
# at the same dimension (y)

ColorCorrect1.masterSaturation.dimension

An expression on a parameter can reference any other parameter on the same node and may also reference parameters on some other nodes, including:

  • Any other node in the same Group
  • If this node belongs to a sub-group, it may reference the Group node itself using the special variable thisGroup
  • If this node is a Group itself, it may reference any node within its sub-group by prefixing thisNode, e.g:

thisNode.Blur1

# Assuming we are editing an expression on the disabled parameter of the # Group1.Blur1 node and that the Group1 node has a boolean parameter, # that was created with a script-name enableBlur, # we could write an expression referencing enableBlur # to enable or disable the internal Blur1 node as such:

thisGroup.enableBlur

To easily get the input of a node, you may use the variable input followed by the index, e.g:

# Assuming the input 0 of the Blur1 node is a Merge node, we
# can reference the operator param of the input node
Blur1.input0.operator
Animated parameters

A parameter may be animated with keyframes. Similarly, each curve may be different for each project view if the user split views for the parameter.

To retrieve the value at a different frame and view than the frame and view for which the expression, is being evaluated you may specify it in arguments:

# Returns the value at the current frame for the current view
Blur1.size.x

# Returns the value at frame + 1 for the current view
Blur1.size.x(frame + 1)

# Returns the value at frame + 1 for the given view
Blur1.size.x(frame + 1, 'Right')
Pre-defined variables

When the expression is called, a number of pre-declared variables can be used:

  • thisNode: It references the node holding the parameter being edited. This can only

be used to reference parameters on the current node or sub-nodes if this node is a Group

  • thisGroup: It references the group containing thisNode. This is useful to reference

a parameter on the group node containing this node

  • thisParam: It references the param being edited. This is useful to reference a value

on the parameter on which the expression is evaluated

  • thisItem: If the expression is edited on a table item such as a Bezier or a Track

this is the item holding the parameter to which the expression is being edited

  • dimension: It indicates the dimension (0-based index) of the parameter on which the expression

is evaluated, this can only be used after a parameter, e.g: Blur1.size.dimension

  • app: References the project settings. This can be used as a prefix to reference

project parameters, e.g: app.outputFormat

  • frame: It references the current time on the timeline at which the expression is evaluated

this may be a floating point number if the parameter is referenced from a node that uses motion blur. If the parameter is a string parameter, the frame variable is already a string otherwise it will be a scalar.

  • view: It references the current view for which the expression is evaluated.

If the parameter is a string parameter, the view will be the name of the view as seen in the project settings, otherwise this will be a 0-based index.

Script-name of a node or parameter

The name of a parameter or Node can be returned in an expression using the attribute name:

thisNode.name
thisNode.input0.name
thisKnob.name
...
Converting numbers to string

You can convert numbers to string with the str(value, format, precision) function.

The format controls how the number will be formatted in the string. It must match one of the following letters:

  • e format as [-]9.9e[+|-]999
  • E format as [-]9.9E[+|-]999
  • f format as [-]9.9
  • g use e or f format, whichever is the most concise
  • G use E or f format, whichever is the most concise

A precision is also specified with the argument format. For the ‘e’, ‘E’, and ‘f’ formats, the precision represents the number of digits after the decimal point. For the ‘g’ and ‘G’ formats, the precision represents the maximum number of significant digits (trailing zeroes are omitted).

Example:

str(2.8940,'f',2) = "2.89"
Effect Region of Definition

It is possible for an expression to need the region of definition (size of the image) produced by an effect. This can be retrieved with the variable rod*

The rod itself is a vector variable containing 4 scalar being in order the left, bottom, right and top coordinates of the rectangle produced by the effect.:

# Expression on the translate.x parameter of a Transform node
input0.rod[0]
Current parameter animation

To achieve complex motion design, (see examples below such as loop) an expression may need to access the animation of the parameter for which the expression is evaluated. To access the underlying animation of a parameter the curve(frame, dimension, view)() function can be used:

# Loop a parameter animation curve over the [firstFrame, lastFrame] interval
firstFrame = 0
lastFrame = 10
curve(((frame - firstFrame) % (lastFrame - firstFrame + 1)) + firstFrame)
Random

Some expression may need to use a pseudo random function. It is pseudo random because the results of the random function are reproducible for each frame and seed.

ExprTk.random([seed=0, min=0., max=1.])
Parameters:
  • seedfloat
  • minfloat
  • maxfloat
Return type:

float

Returns a pseudo-random value in the interval [min, max[. The value is produced such that for a given parameter it will always be the same for a given time on the timeline, so that the value can be reproduced exactly. However, successive calls to this function within the same expression will yield different results after each call. By default the random is seed with the current frame, meaning that 2 expressions using random and evaluated at the same frame will always return the same number. If you want to force a different number for an expression, you can set the seed parameter to a non zero value.

ExprTk.randomInt([seed=0, min=INT_MIN, max=INT_MAX])
Parameters:
  • seedint
  • minint
  • maxint
Return type:

int

Same as random(seed, min,max) but returns an integer in the range [min,max[

Advanced noise functions

More advanced noise functions are available such as fractional brownian motion. All the functions available in Python in the NatronEngine.ExprUtils class are also available to basic expressions. See the their documentation in the Python API as they have the same signature.

Tutorials

Writing documentation

This quick tutorial will guide you through the creation/modification of documentation for Natron and the plugins.

Natron Manual
Writing contributions

Contributing to the Natron documentation is rather easy. The source for the documentation is located in the Documentation/source folder.

The documentation is generated using Sphinx, and the source files are in reStructuredText format.

Most likely you will want to contribute to the User Guide. The source files for the guide are located in the directory named Documentation/source/guide. If you want to contribute to an already existing document just open the file in your favorite (plain) text-editor and do your modifications.

Note

The following files are generated automatically and can thus not be edited:

  • The _group.rst file, and any file with a name starting with _group.
  • The _prefs.rst.
  • The documentation for each individual plugin, which can be found in the Documentation/source/plugins directory (see Plugins Manual).

If you prefer editing with LibreOffice (or even MSWord), just keep the document simple (use styles for section headers, don’t try to format too much, etc.), and use pandoc to get a first working version in reStructuredText format: pandoc your_document.docx -t rst -o output_doc.rst

This reStructuredText file will probably require a few touch-ups afterwards, but it is usually a good starting point.

Submitting contributions

To send your contributions, the best way is to follow the procedure below. However, if you wrote a nice piece of documentation, in any standard format, and have difficulties following that procedure, do not hesitate to ask for assistance on the Natron forum, or to file a GitHub issue, with your document attached to your message.

The standard procedure is the following:

  • Fork https://github.com/NatronGitHub/Natron using your github account.
  • On your fork, create a branch from the RB-2.3 branch (do not use the master branch), and give it a name like “documentation-keying” if you are going to write the keying doc (which we really need).
  • To add your doc, you can either:
    • Clone the repository to your computer, edit and add files, commit your changes locally (the github desktop application is easy to use), and then push your changes,
    • Or edit the files directly on github. See tutorials-hsvtool.rst for en example (you will probably need to fork the repository first, see below, and browse to that file on your fork). Click on the pencil icon on the top right. You get an editable the text view and can get a preview by clicking on the preview tab on top.
  • Then, submit a pull request to the RB-2.3 branch on the main repository from your branch (there is a button to submit a pull request when you view your fork on github). Give an accurate description of the pull request, and remember to follow the Contributor Covenant Code of Conduct, as with all contributions to Natron or the plugins. The Natron maintainers can either accept it as it is, or ask for a few modifications.

You can view the formatted documentation on your github repository, as explained above, but you can also preview your modifications by using pandoc to convert it to another format, or install Sphinx and recompile the whole documentation. On Linux and Mac you can install Sphinx through your package manager (using MacPorts type sudo port install py27-sphinx py27-sphinx_rtd_theme, on HomeBrew type brew install sphinx-doc; /usr/local/opt/sphinx-doc/libexec/bin/pip3 install sphinx_rtd_theme`, on Linux type pip install sphinx sphinx_rtd_theme), on Windows refer to the Sphinx documentation.

When you have Sphinx installed go to the Documentation folder and launch the following command:

sphinx-build -b html source html

The Natron documentation has now been generated in the Documentation/html folder. Open Documentation/html/index.html in your web browser to review your changes.

When your are satisfied with your modifications do a pull request against the master repository on GitHub.

Plugins Manual

The documentation for each plugin contains two parts:

  • The main documentation, including the short description, and the documentation for individual parameters. This part of the documentation is available in the C++ source file of each plugin.
  • An extra documentation, in the form of a Markdown file in the plugin bundle, named Contents/Resources/pluginId.md (in the same directory as the plugin icon files), where pluginId is the full plugin identifier (e.g. net.sf.openfx.MergePlugin). The extra documentation is inserted after the Description section and before the Inputs section of the generated documentation.
Main Plugin Documentation

Editing or adding the main documentation for the Natron plugins requires you to edit the C++ source file for each plugin. Usually the plugin(s) has a kPluginDescription define where you can edit the description found when hovering or clicking the ? button of the plugin properties panel in Natron.

Let us say you want to edit the description in the Checkerboard plugin.

  1. Fork the https://github.com/NatronGitHub/openfx-misc repository on GitHub.
  2. Open the file Checkerboard/Checkerboard.cpp in your favorite (plain) text-editor

Navigate to the line #define kPluginDescription, where you can edit the description. Line breaks are added with \n.

You will also notice that each parameter has a hint define, for example the Checkerboard has #define kParamBoxSizeHint, #define kParamColor0Hint etc. These describe each parameter in the plugin and shows up when you hover the parameter in Natron, or access the HTML documentation online or through Natron.

To test your modifications, you must build the plugin(s) and load them in Natron, refer to each plugin bundle on GitHub on how to build the plugin(s). Click the ? button of the plugin properties panel in Natron to check your modifications.

Markdown

The plugin description and parameters optionally supports Markdown format. This enables you to have more control over how the information is displayed.

Enabling Markdown on a plugin requires some modifications, as the plugin must tell the host (Natron) that it supports Markdown on the description and/or parameters. See the Shadertoy plugin for an example of how this works.

Basically you need to add desc.setPluginDescription(kPluginDescriptionMarkdown, true); in the describe function for each plugin. If you are not comfortable with this, contact the repository maintainer(s) and ask them to enable Markdown for you.

Submitting contributions

As with the Natron Manual, the standard way of submitting your contributions is by forking the relevant plugins repo on GitHub (openfx-misc, openfx-io, openfx-arena or openfx-gmic) and submitting a pull request to the master branch of that repo.

However, if you wrote a nice piece of documentation, in any standard format, and have difficulties following that procedure, do not hesitate to ask for assistance on the Natron forum, or to file a GitHub issue, with your document attached to your message.

HSVTool

The HSVTool node converts the input color space to a HSV color space and converts the adjusted values back to the image input color space for further processing for the output. The HSVTool node is used to adjust the HSV channel components of an image the the Read node stream. It’s basic operation are to adjust the Hue: which is the color of the input image, Saturation: which is the color range of the input image, and Brightness: which is the color value level and the grayscale of the input image.

Each section has a rang controls that can be adjusted to limit the effects of a node by narrowing the input color ranges.

What are some standard work-flow using HSVTool?

  1. You can do secondary color corrections or color replacements with the source/destination eyedropper tool.
  2. You can use the HSVTool for linear/color keying.
  3. You can do an overall color shift by using the rotation range adjuster in the Hue parameters etc.
_images/hsvtool_01.png

The following screen captures are based on a single pixel selection without manual component modifications. You will see different alpha mattes display based on the alpha output components.

_images/hsvtool_02.png

The image above is the result of a single color pixel selection using the blue destination replacement color.

Brightness adjustment ranges
_images/hsvtool_03.png

This is when you make adjustments to Hue, Saturation, and Brightness to limit the input color ranges for the desired effect. You can look at the third viewer on the right that has matte/alpha generated by the color selection key using the source color eyedropper. This is the alpha interpretation of the alpha output component which is the to Hue.

_images/hsvtool_04.png

There are several alpha output component that the HSVTool uses to limit effects. The next images are the results of the output alpha mode from the HSVTool.

Note

Each of the matte generated displays are based from the colors that are spread across the image on a single pixel selection and it HSV values.

_images/hsvtool_05.png
_images/hsvtool_06.png
_images/hsvtool_07.png

By using a low resolution and/or compressed image you will see the artifacts in the alpha channel. This makes it harder to do a replacement or secondary color correction. Is is evident that the blue channel has the most artifacts/noise, you can use the CImgDenoise or CImgBlur node and blur one or two pixels in the blue channel to soften the pixel edges. This technique will not always work, remember to apply dynamic range applications when using the HSVTool. You can only push the Saturation and Brightness so far. Also remember that HSVTool need color input in order to apply any color filtering even though it can output greyscale and matte data.

HSVTool Keyer

The HSVTool can be used as a color keyer. It uses the same principles as the ChromaKeyer and the Keyer nodes. What separates the HSVTool as a keyer is that the matte is inverted with it’s selection.

When you need to pull a key with the ChromaKeyer the key color is outputted as black or represents a transparency. See node grap below for an example.

_images/hsvtool_08.png

The image below is the ChromaKeyer parameters panel. You can see that the eyedropper has a chroma green selection from the input image. You may also notice the acceptance angle is very high, this is because the source material is compressed.

_images/hsvtool_09.png

As you can see from the panel the chromakey subtracted the chroma green, replacing it with black/transparent. The “Key Lift” and “Key Gain” clamps the black/white to make a clean matte from the keyed selection.

Even if the chromakey generates transparency from the node, it still outputs a black and white matte that can be used as an inverted mask or holdout matte to apply needed filter effects.

Note

A holdout matte is a section of your image that tells the keyer not to key the selected area. A holdout matte is commonly used to define a area within your image that might have similar colors to the color being keyed.

The node graph below is using the same green screen image when pulling a key with the HSVTool. The alpha output shows up as the white color. This HSVTool does not subtract the color to generate a matte, as oppose to the ChromaKeyer and Keyer nodes that subtracts the color to generate a matte. If you are concerned about color spaces, ChromaKeyer and Keyer process data in RGB color space and the HSVTool process in HSV color space.

_images/hsvtool_10.png

The image below is the HSVTool parameters panel. You can see that the source color eyedropper operator has a chroma green selected. As you look further down the panel you will notice the Hue, Saturation, and Brightness parameters which has all the values the make up the chroma green selection.

_images/hsvtool_11.png

The important part to remember is that Hue, Saturation, and Brightness are used to generate and adjust the matte(s) based on the output alpha mode. The image output alpha is set to min(All), when selected, Hue, Saturation, and Brightness can be used to adjust the matte/mask output.

There are eight output alpha modes. The only mode that can’t generate a matte is the “Source” mode. Even if there’s no matte generated you can still do color replacements and color corrections.

_images/hsvtool_12.png

The image above displays two HSVTool nodes that is keying the same input, but generating two different mattes based on the output alpha. The middle viewer is the Hue mode output. The viewer on the right is the min(Hue, Saturation) mode output. When you are working with compressed source images the output alpha modes will yield different results.

_images/hsvtool_13.png

Note

If you need more control on the alpha/matte output, the ColorLookup node can help adjusting edges.

Using PanoTools projects within Natron

Those are preliminary notes on using PanoTools or Hugin projects from within Natron.

Creating a PanoTools (pto) project
Using the Hugin GUI
Using command-line tools

Full details on using command-line tools are given in the Panorama scripting in a nutshell documentation.

On macOS, if Hugin was installed using homebrew, the tools are available in various directories, and they can be added to the PATH using:

PATH="$PATH:/Applications/Hugin/tools_mac:/Applications/Hugin/Hugin.app/Contents/MacOS:/Applications/Hugin/HuginStitchProject.app/Contents/MacOS"

Here is an example of running the panorama tools from a set of JPEG images (with suffix .jpg) placed in the current directory to generate e perspective panorama (other options are described in the documentation):

pto_gen -o project.pto *.JPG
cpfind --multirow -o project.pto project.pto

celeste_standalone -i project.pto -o project.pto
cpclean -v --output project.pto project.pto

autooptimiser -a -l -s -m -o project.pto project.pto

nona -m TIFF_m -o project project.pto

enblend --save-masks -o panorama.tif project*.tif

The result is:

  • A project.pto file, which is the Hugin project itself
  • The project*.tif images, which are images warped to the reference projection.
  • The mask-*.tif images, which are masks generated by enblend.
  • The panorama.tif image, which is the final panorama.
Using Hugin/PanoTools parameters in Natron

The pto file syntax is described is the PTOptimizer and PTStitcher docs.

This file can be viewed and edited in any text editor.

Project size

The project size, or format, should be set to the panorama size, which is given in pixels on the p line (at the start of the file).

Distortion correction

The distortion correction parameters for the input images are given in the i lines (one for each image).

The values for the a, b, c, d, e, g, t parameters should be entered in a LensDistortion node, with Model/model=PanoTools and Direction/direction=Undistort, placed after the Read node for each input image or video. The script name for these values are pt_a, pt_b, pt_c, pt_d, pt_e, pt_g, pt_t.

Note that if all images share the same distortion parameters (this is written as a=0 b=0 c=0 d=0 e=0 g=0 t=0 on the i line), the LensDistortion node can be cloned in Natron (right-click on node, Edit, Clone Nodes).

Projection

The projection (which can be performed by the Nona tool) can be done using Card3D nodes placed after each LensDistortion node.

Each Card3D node must have its Transform Order/cardXFormOrder set to STR, and the Rotation Order/cardRotOrder should be left to the default value (ZXY). Be careful, these are neither the Axis nor the Cam Transform Order, which are in the two first groups of the Card3Dnode.

Set the Output Format to Project.

The r p and y values from the i line are roll, yaw, pitch angles. Their values should be put in the Rotate parameter of the Card3D (script name is cardRotate), using the following convention: cardRotate.x = p, cardRotate.y = -y, cardRotate.z = -r.

The v value from the i line corresponds to the horizontal field of view, and has to be converted to an aperture value. The Lens-In H.Aperture/lensInHAperture param should be set to 2*tan(v*pi/360). This expression can be directly typed in the value field, with v replaced by the actual value from the corresponding i line of the pto file.

Setup all the Card3D nodes for each input image that way.

Camera

In Natron 2, the camera used by the Card3D node is set in the Cam group at the top of the parameters list.

In the Card3D node for the first image, unfold this group, and unfold the Cam Projection group.

The v value on the p line (usually at the top of the pto file) gives the horizontal field of view of the output panorama.

Set the Focal Length/camfocal to 1., and set the Horiz. Aperture/camhaperture to 2*tan(v*pi/360), replacing v with its actual value.

You can then copy these two parameters to all the Card3D nodes, or - even better - link these parameters, so that the output camera for the panorama can then be modified: Right-click on the parameter from the first Card3D, Copy Link, then right-click on the same parameter of every other Card3D node, Paste Link.

If you intend to modify the camera orientation later, you can also link the same way the Rotate/camRotate parameter (those for the camera, not the card).

Note that when the Natron Card3D node is used in Nuke (where it appears as Card3DOFX), the node has an external Cam input, to which a Camera node may be connected. There may be a similar concept in future versions of Natron.

Building the panorama in Natron
First sketch: overlap the images

Make sure that the Output Components parameter in all readers is set to RGBA, so that images have a transparent value outside of their domain.

Now, connect the outpput of the first Card3D to the B input of a Merge node, connect the secont to the A input, the third to the A2 input, etc…

The output of the Merge node should show a first panorama, obtained by overlapping all images.

Drawing the masks

Add a Roto node after each LensDistortion, before each Card3D.

Only leave connected the A and B inputs to the Merge node to the two first Card3D nodes.

Check Premultiply in each Roto node, check that only the A channel is affected by Roto in its parameters, and start editing the roto mask on the second image, for which the LensDistortion output is connected to the A input of the Merge, while viewing the output of the Merge.

Set the compositing operator of each roto shape to “min” instead of “over”, so that the original image alpha gets masked by the roto shape.

Do not forget to add feather, especially in the overlap area.

Then, reconnect the A2 input to the third Card3D, and start editing its roto mask, always in “min” compositing mode.

Do the same with A3, A4, etc… and you should end up with a full panorama.

Future work
Camera response

See Camera response curve and Vig_optimize.

The values Ra Rb Rc Rd Re on the i line encode a color response curve (EMoR). See EMoRParamsin the hugin source code.

Exposure and color

See Vignetting and Vig_optimize.

Eev encodes the exposure, see ExposureValue in the hugin source code.

Er and Eb encode the red and blue multipliers, see WhiteBalanceRed and WhiteBalanceBlue in the hugin source code.

Vignetting

See Vignetting and Vig_optimize.

Va is always 1, see VigCorrMode in the hugin source code.

Vb Vc Vd encode the degree 2, 4 and 6 coefficients for vignette correction, see RadialVigCorrCoeff in the hugin source code.

Vx and Vy encode the vignetting center shift, see RadialVigCorrCenterShift in the hugin source code.

Blending
  • importing enblend masks, using them as roto masks
  • executing enblend externally (using RunScript maybe?)

Vector graphics workflow

_images/svgworkflow_01.png

Software development is constantly growing. The film and multimedia industry are coming together as partners to provide a one stop shop by allowing applications to communicate via different file formats. One of the formats that have proven to be useful in both industries is the SVG (Scalable Vector Graphics) format. Its architecture algorithm is based on mathematical expressions. In simpler terms, in doesn’t suffer image noise & artifacts like bitmap formats such as PNG, TIFF, JPG and etc.

Inkscape’s SVG format uses multiple layers and paths, but most graphics applications can only parse this as a flat bitmap. There will times when an artist may want to animate and/or modify those layers in a compositing program but can’t due to limitation in the SVG importer. Natron however supports all layers and paths in the SVG file, this enables enhanced control over the vector graphics.

This tutorial will show you how to use vector graphics from Inkscape in Natron.

Inkscape
_images/svgworkflow_02.png

Inkscape has multiple ways to create vector graphics to be saved and imported into Natron. The default is to first create your document layout. This entails formatting the resolution for the project upon which your vector graphics will be displayed. Inkscape starts with one layer and you can draw and type your graphics on that layer or additional layers. You can then save the project to SVG file.

This image is SVG letters being converted to a group and layers for each word so that they may have their own layer/alpha channel in Natron.

The image below is the same vector letters being converted to paths and eventually ungrouping each of the vector letters so that they may have their own layer and alpha channel in Natron.

_images/svgworkflow_03.png

Note

Remember to make sure that you convert your objects to paths, it is highly advisable to name each path with its separate id name. It will make it much easier to find Color.RGB and alpha channel names in Natron after loading the SVG file in the node graph.

It is also possible and good practice to select objects/paths and create groups of them. This will allow easy animation work-flows without having to duplicate animated key-frames if needed. Those groups will also show up as Color.RGB and Alpha channels in Natron.

Natron

The image below is Natron with the SVG file loaded. We have two viewers displaying the Color.RGB and alpha channels generated from the SVG file.

_images/svgworkflow_04.png

After you have loaded the file, you can check the Color.RGB/Alpha Channels headers to see how the layers, paths and groups are read. The ReadSVG node is multi-plane aware. The next few images are Natron screen captures of the headers, merge and shuffle nodes.

Merge Node Channels
Merge Paths Channels

Note

To clarify the Merge: Paths Channels image. In the SVG image, I broke apart the vector characters and converted them to paths. Then each letter of the SVG was giving the name assigned to that letter. That information got saved as individual Color.RGB/Alpha channels.

Be sure to look carefully at the Color.RGB and alpha headers in the images below. When your finished designing your vector document with layers/paths/groups, this is where the channels are displayed.

_images/svgworkflow_07.png
_images/svgworkflow_08.png

The Shuffle and Merge nodes are used to access multi-plane layers. Though they both can process the different SVG files objects, paths, layers, they work differently. As you can see in the image on the left the shuffle node display every channel(s) from a file and also copy channels from other files into the “A” input from the “B” input.

The merge node only perform mathematical blending operations on the inputs “B” and “A:A1000”. In order to access the alpha channels from the SVG file you must use the maskChannel mask inputs.

So plan your work before you start a project. Organization is key. Make sure that Layer(s), Object(s), Path(s) and Group(s) have logical naming conventions.

_images/svgworkflow_09.png

The node graph below shows how to extract individual layers using the shuffle node and the merge node. Both can extract the RGB layers and individual paths from an SVG file, but the Shuffle node allow you to pipe any of the layers or single channels to another node mask input.

Alternative Matte Extraction Tutorial

_images/ArticleCoverPage.jpg

In the world of vfx in current films these days, it is hard to even phathom that pulling keys (aka chromakeying) or generally just creating mattes from images is not common place. Today I want to share some features in a few nodes that are in Natron VFX Digital Compositor. The nodes that I want to discuss are Despill, Ip_ChillSpill and ColorSuppression. You can guess by the name the functions that they perform. Basically, they subtract any blue or green screen spillage that happens to contaminate your foreground objects during the production process. These types of functions are common place in every post-production facilities in the industry. It doesn’t matter if you are a beginner wanting to produce your own short films or a professional working on block buster films. The needs are the same. The attached image is a greenscreen image that I pulled off google to demonstrate what the Natron developers had implemented to take these despillers to another level or just added functionality.

_images/HeBeGreeen.jpg

The added functionality is having the ability to use the suppressed or despill color information and convert it to a matte or alpha. I am unaware if any other compositing applications has these abilities. Natron is my main compositing app and from time to time I use these despilling node algorithms to help generate masks, general mattes and scaled alphas. This is Natron’s node graph pipeline for each node that I will be discussing. The pipeline for each node is really simple. You just connect the green/blue screen footage to the input of the nodes, adjust whatever you have to adjust, click on the very simple knob that says “Spillmap to Alpha” if you are using the Despill node, “Shuffle Spillmatte to Alpha” if you are using the community openfx plugin called Ip_ChillSpill Node, and “Output: Image, Alpha & Image and Alpha” if you are using the ColorSuppression node.

_images/ArticleCoverPage.jpg

The first screenshot demonstration if for the node Ip_ChillSpill. This despilling node has the most of features and functions that I can tell that exist amongst all the despilling nodes. in the image below you will see the spill suppression on the left and the alpha channel from selecting “Shuffle Spillmatte to Alpha” on the right.

_images/Ip_ChillSpill-FullComp.jpg

Now just selecting the Shuffle Spillmatte to Alpha feature is not some magic trick and you get a perfect matte, not by a long shot. For a matter a fact its not for any of them. Attached are example of the nodes in their default state before the scaling process begins. The first image is the Ip_ChillSpill default matte output and the second in the ColorSuppression default matte output. It looks like if I was trying to use the HSVTool Node to pull a Saturation or Brightness Key. You can read more about that in my HSVTool node tutorial. I used a very underated and under used node amongst beginners called the ColorLookup Node. You can be very familiar with the node if you have used Photoshop or Gimp’s curve tool.

_images/Ip_ChillSpill-default.jpg

Here are the nodes and their settings to show what I had to do to get it to scale my suppression mattes. The key tool is to use the ColorLookup Node connected after the despilling nodes. The ColorLookup Node four color channels and the channel that you use the scale your mattes is the “alpha curve channel”. The bottom left of the alpha curve is used the to crush your blacks/shadows and the top right is used to extend your white/highlights. In the ColorLookup Node you will also see a feature called “Luminance Math”. This feature will yield its full benefits based off the resolution and color spaces of your footage. The ColorLookup node is very powerful in a sense because the channel curves can have multiple points to limit its effects.

_images/ColorSuppression-default.jpg

As you can see these nodes all perform the same functions but some has different parameters to accomplishes the same thing and well as providing other color processing effects. Here are some screen captures of the effects using the ColorLookup Node.

_images/Ip_ChillSpill.jpg
_images/AllColorLookup.jpg

Now this by node means a primary replacement for powerful keying node in Natron. The extended functionality should only be considered as compliment to Chromakeyer, PIK/PIK Color and Keyer nodes. Just remember that the Here are some screen captures of the effects using the ColorLookup node is needed to scaled that matte. Also this process doesn’t treat your edges with a choking or eroding effect. You would have to experiment with some of the filters to process them. Now you can try and cheat by using the Shuffle Node to convert to this matte output to an real alpha channel and maybe you can process your edges directly as if you were coming out of a keyer. You will need to do some serious testing. After you have done that, please feel free to talk about it and join NatronNation and read my blog.

Reference Guide

The first section in this manual describes the various options available from the Natron preference settings. The next section gives the documentation for the various environment variables that may be used to control Natron’s behavior. It is followed by one section for each node group in Natron. Node groups are available by clicking on buttons in the left toolbar, or by right-clicking the mouse in the Node Graph area.

Preferences

General

Always check for updates on start-up

When checked, Natron will check for new updates on start-up of the application.

Auto-save trigger delay

The number of seconds after an event that Natron should wait before auto-saving. Note that if a render is in progress, Natron will wait until it is done to actually auto-save.

Enable Auto-save for unsaved projects

When activated Natron will auto-save projects that have never been saved and will prompt you on startup if an auto-save of that unsaved project was found. Disabling this will no longer save un-saved project.

Appear to plug-ins as

Natron will appear with the name of the selected application to the OpenFX plug-ins. Changing it to the name of another application can help loading plugins which restrict their usage to specific OpenFX host(s). If a Host is not listed here, use the “Custom” entry to enter a custom host name. Changing this requires a restart of the application and requires clearing the OpenFX plugins cache from the Cache menu.

Threading

Number of render threads (0=“guess”)

Controls how many threads Natron should use to render.

-1: Disable multithreading totally (useful for debugging)

0: Guess the thread count from the number of cores.

Number of parallel renders (0=“guess”)

Controls the number of parallel frame that will be rendered at the same time by the renderer.A value of 0 indicate that Natron should automatically determine the best number of parallel renders to launch given your CPU activity. Setting a value different than 0 should be done only if you know what you’re doing and can lead in some situations to worse performances. Overall to get the best performances you should have your CPU at 100% activity without idle times.

Effects use the thread-pool

When checked, all effects will use a global thread-pool to do their processing instead of launching their own threads. This suppresses the overhead created by the operating system creating new threads on demand for each rendering of a special effect. As a result of this, the rendering might be faster on systems with a lot of cores (>= 8).

WARNING: This is known not to work when using The Foundry’s Furnace plug-ins (and potentially some other plug-ins that the dev team hasn’t not tested against it). When using these plug-ins, make sure to uncheck this option first otherwise it will crash Natron.

Max threads usable per effect (0=“guess”)

Controls how many threads a specific effect can use at most to do its processing. A high value will allow 1 effect to spawn lots of thread and might not be efficient because the time spent to launch all the threads might exceed the time spent actually processing.By default (0) the renderer applies an heuristic to determine what’s the best number of threads for an effect.

Render in a separate process

If true, Natron will render frames to disk in a separate process so that if the main application crashes, the render goes on.

Append new renders to queue

When checked, renders will be queued in the Progress Panel and will start only when all other prior tasks are done.

Rendering

Convert NaN values

When activated, any pixel that is a Not-a-Number will be converted to 1 to avoid potential crashes from downstream nodes. These values can be produced by faulty plug-ins when they use wrong arithmetic such as division by zero. Disabling this option will keep the NaN(s) in the buffers: this may lead to an undefined behavior.

Copy input image before rendering any plug-in

If checked, when before rendering any node, Natron will copy the input image to a local temporary image. This is to work-around some plug-ins that write to the source image, thus modifying the output of the node upstream in the cache. This is a known bug of an old version of RevisionFX REMap for instance. By default, this parameter should be leaved unchecked, as this will require an extra image allocation and copy before rendering any plug-in.

RGB components support

When checked Natron is able to process images with only RGB components (support for images with RGBA and Alpha components is always enabled). Un-checking this option may prevent plugins that do not well support RGB components from crashing Natron. Changing this option requires a restart of the application.

Transforms concatenation support

When checked Natron is able to concatenate transform effects when they are chained in the compositing tree. This yields better results and faster render times because the image is only filtered once instead of as many times as there are transformations.

GPU Rendering

Active OpenGL renderer

The currently active OpenGL renderer.

OpenGL renderer

The renderer used to perform OpenGL rendering. Changing the OpenGL renderer requires a restart of the application.

No. of OpenGL Contexts

The number of OpenGL contexts created to perform OpenGL rendering. Each OpenGL context can be attached to a CPU thread, allowing for more frames to be rendered simultaneously. Increasing this value may increase performances for graphs with mixed CPU/GPU nodes but can drastically reduce performances if too many OpenGL contexts are active at once.

OpenGL Rendering

Select whether to activate OpenGL rendering or not. If disabled, even though a Project enable GPU rendering, it will not be activated.

Project Setup

First image read set project format

If checked, the project size is set to this of the first image or video read within the project.

Auto-preview enabled by default for new projects

If checked, then when creating a new project, the Auto-preview option is enabled.

Auto fix relative file-paths

If checked, when a project-path changes (either the name or the value pointed to), Natron checks all file-path parameters in the project and tries to fix them.

Use drive letters instead of server names (Windows only)

This is only relevant for Windows: If checked, Natron will not convert a path starting with a drive letter from the file dialog to a network share name. You may use this if for example you want to share a same project with several users across facilities with different servers but where users have all the same drive attached to a server.

Documentation

Documentation Source

Documentation source.

Documentation local port (0=auto)

The port onto which the documentation server will listen to. A value of 0 indicate that the documentation should automatically find a port by itself.

User Interface

Warn when a file changes externally

When checked, if a file read from a file parameter changes externally, a warning will be displayed on the viewer. Turning this off will suspend the notification system.

Prompt with file dialog when creating Write node

When checked, opens-up a file dialog when creating a Write node

Refresh viewer only when editing is finished

When checked, the viewer triggers a new render only when mouse is released when editing parameters, curves or the timeline. This setting doesn’t apply to roto splines editing.

Linear color pickers

When activated, all colors picked from the color parameters are linearized before being fetched. Otherwise they are in the same colorspace as the viewer they were picked from.

Maximum number of open settings panels (0=“unlimited”)

This property holds the maximum number of settings panels that can be held by the properties dock at the same time.The special value of 0 indicates there can be an unlimited number of panels opened.

Value increments based on cursor position

When enabled, incrementing the value fields of parameters with the mouse wheel or with arrow keys will increment the digits on the right of the cursor.

When disabled, the value fields are incremented given what the plug-in decided it should be. You can alter this increment by holding Shift (x10) or Control (/10) while incrementing.

Default layout file

When set, Natron uses the given layout file as default layout for new projects. You can export/import a layout to/from a file from the Layout menu. If empty, the default application layout is used.

Load workspace embedded within projects

When checked, when loading a project, the workspace (windows layout) will also be loaded, otherwise it will use your current layout.

Color Management

OpenColorIO configuration

Select the OpenColorIO configuration you would like to use globally for all operators and plugins that use OpenColorIO, by setting the “OCIO” environment variable. Only nodes created after changing this parameter will take it into account, and it is better to restart the application after changing it. When “Custom config” is selected, the “Custom OpenColorIO config file” parameter is used.

Custom OpenColorIO configuration file

OpenColorIO configuration file (config.ocio) to use when “Custom config” is selected as the OpenColorIO config.

Warn on OpenColorIO config change

Show a warning dialog when changing the OpenColorIO config to remember that a restart is required.

Caching

Aggressive caching

When checked, Natron will cache the output of all images rendered by all nodes, regardless of their “Force caching” parameter. When enabling this option you need to have at least 8GiB of RAM, and 16GiB is recommended.

If not checked, Natron will only cache the nodes which have multiple outputs, or their parameter “Force caching” checked or if one of its output has its settings panel opened.

Maximum amount of RAM memory used for caching (% of total RAM)

This setting indicates the percentage of the total RAM which can be used by the memory caches.

System RAM to keep free (% of total RAM)

This determines how much RAM should be kept free for other applications running on the same system. When this limit is reached, the caches start recycling memory instead of growing. This value should reflect the amount of memory you want to keep available on your computer for other usage. A low value may result in a massive slowdown and high disk usage.

Maximum playback disk cache size (GiB)

The maximum size that may be used by the playback cache on disk (in GiB)

Maximum DiskCache node disk usage (GiB)

The maximum size that may be used by the DiskCache node on disk (in GiB)

Disk cache path

WARNING: Changing this parameter requires a restart of the application.

This points to the location where Natron on-disk caches will be. This variable should point to your fastest disk. This parameter can be overriden by the value of the environment variable NATRON_DISK_CACHE_PATH.

If the parameter is left empty or the location set is invalid, the default location will be used.

Wipe Disk Cache

Cleans-up all caches, deleting all folders that may contain cached data. This is provided in case Natron lost track of cached images for some reason.

Viewer

Viewer textures bit depth

Bit depth of the viewer textures used for rendering. Hover each option with the mouse for a detailed description.

Viewer tile size is 2 to the power of…

The dimension of the viewer tiles is 2^n by 2^n (i.e. 256 by 256 pixels for n=8). A high value means that the viewer renders large tiles, so that rendering is done less often, but on larger areas.

Checkerboard tile size (pixels)

The size (in screen pixels) of one tile of the checkerboard.

Checkerboard color 1

The first color used by the checkerboard.

Checkerboard color 2

The second color used by the checkerboard.

Automatically enable wipe

When checked, the wipe tool of the viewer will be automatically enabled when the mouse is hovering the viewer and changing an input of a viewer.

Automatically enable proxy when scrubbing the timeline

When checked, the proxy mode will be at least at the level indicated by the auto-proxy parameter.

Max. opened node viewer interface

Controls the maximum amount of nodes that can have their interface showing up at the same time in the viewer

Use number keys for the viewer

When enabled, the row of number keys on the keyboard is used for switching input (<key> connects input to A side, <shift-key> connects input to B side), even if the corresponding character in the current keyboard layout is not a number.

This may have to be disabled when using a remote display connection to Linux from a different OS.

Nodegraph

Auto Scroll

When checked the node graph will auto scroll if you move a node outside the current graph view.

Auto-turbo

When checked the Turbo-mode will be enabled automatically when playback is started and disabled when finished.

Snap to node

When moving nodes on the node graph, snap to positions where they are lined up with the inputs and output nodes.

Maximum undo/redo for the node graph

Set the maximum of events related to the node graph Natron remembers. Past this limit, older events will be deleted forever, allowing to re-use the RAM for other purposes.

Changing this value will clear the undo/redo stack.

Disconnected arrow length

The size of a disconnected node input arrow in pixels.

Auto hide masks inputs

When checked, any diconnected mask input of a node in the nodegraph will be visible only when the mouse is hovering the node or when it is selected.

Merge node connect to A input

If checked, upon creation of a new Merge node, or any other node with inputs named A and B, input A is be preferred for auto-connection. When the node is disabled, B is always output, whether this is checked or not.

Plug-ins

Use bundled plug-ins

When checked, Natron also uses the plug-ins bundled with the binary distribution.

When unchecked, only system-wide plug-ins found in are loaded (more information can be found in the help for the “Extra plug-ins search paths” setting).

Prefer bundled plug-ins over system-wide plug-ins

When checked, and if “Use bundled plug-ins” is also checked, plug-ins bundled with the Natron binary distribution will take precedence over system-wide plug-ins if they have the same internal ID.

Enable default OpenFX plugins location

When checked, Natron also uses the OpenFX plug-ins found in the default location (/Library/OFX/Plugins).

OpenFX plug-ins search path

Extra search paths where Natron should scan for OpenFX plug-ins. Extra plug-ins search paths can also be specified using the OFX_PLUGIN_PATH environment variable.

The priority order for system-wide plug-ins, from high to low, is:

  • plugins bundled with the binary distribution of Natron (if “Prefer bundled plug-ins over system-wide plug-ins” is checked)
  • plug-ins found in OFX_PLUGIN_PATH
  • plug-ins found in /Library/OFX/Plugins (if “Enable default OpenFX plug-ins location” is checked)
  • plugins bundled with the binary distribution of Natron (if “Prefer bundled plug-ins over system-wide plug-ins” is not checked)

Any change will take effect on the next launch of Natron.

PyPlugs search path

Search path where Natron should scan for Python group scripts (PyPlugs). The search paths for groups can also be specified using the NATRON_PLUGIN_PATH environment variable.

Python

After project created

Callback called once a new project is created (this is never called when “After project loaded” is called.)

The signature of the callback is: callback(app) where:

  • app: points to the current application instance

Default after project loaded

The default afterProjectLoad callback that will be set for new projects.

Default before project save

The default beforeProjectSave callback that will be set for new projects.

Default before project close

The default beforeProjectClose callback that will be set for new projects.

Default after node created

The default afterNodeCreated callback that will be set for new projects.

Default before node removal

The default beforeNodeRemoval callback that will be set for new projects.

Load PyPlugs in projects from .py if possible

When checked, if a project contains a PyPlug, it will try to first load the PyPlug from the .py file. If the version of the PyPlug has changed Natron will ask you whether you want to upgrade to the new version of the PyPlug in your project. If the .py file is not found, it will fallback to the same behavior as when this option is unchecked. When unchecked the PyPlug will load as a regular group with the information embedded in the project file.

Print auto-declared variables in the Script Editor

When checked, Natron will print in the Script Editor all variables that are automatically declared, such as the app variable or node attributes.

Appearance

Font

List of all fonts available on your system

Stylesheet file (.qss)

When pointing to a valid .qss file, the stylesheet of the application will be set according to this file instead of the default stylesheet. You can adapt the default stylesheet that can be found in your distribution of Natron.

Main Window

Use black & white toolbutton icons

When checked, the tools icons in the left toolbar are greyscale. Changing this takes effect upon the next launch of the application.

Curve Editor

Environment Variables

What are Environment Variables?

Environment variables are global system variables accessible by all the processes running under the Operating System (OS). Environment variables are useful to store system-wide values such as the directories to search for the executable programs (PATH) and the OS version.

How do I set an environment variable?

Linux

To set an environment variable on Linux, enter the following command at a shell prompt, according to which shell you are using:

  • bash/ksh/zsh: export variable=value
  • csh/tcsh: setenv variable value

where variable is the name of the environment variable (such as OFX_PLUGIN_PATH) and value is the value you want to assign to the variable, (such as /opt/OFX/Plugins). To find out what environment variables are set, use the env command. To remove a variable from the environment, use the following commands:

  • bash/ksh/zsh: export -n variable
  • csh/tcsh: unsetenv variable

To set permanently an environment variable, add the command to your shell’s startup script in your home directory. For Bash, this is usually ~/.bashrc. Changes in these startup scripts don’t affect shell instances already started; try opening a new terminal window to get the new settings, or refresh the curent settings using source ~/.bashrc.

Windows

You can create or change environment variables in the Environment Variables dialog box. If you are adding to the PATH environment variable or any environment variable that takes multiple values, you should separate each value with a semicolon (;).

Windows 8 and Windows 10

To open the Environment Variables dialog box:

  1. In Search, search for and then select: Edit environment variables for your account

To create a new environment variable:

  1. In the User variables section, click New to open the New User Variable dialog box.
  2. Enter the name of the variable and its value, and click OK. The variable is added to the User variables section of the Environment Variables dialog box.
  3. Click OK in the Environment Variables dialog box.

To modify an existing environment variable:

  1. In the User variables section, select the environment variable you want to modify.
  2. Click Edit to open the Edit User Variable dialog box.
  3. Change the value of the variable and click OK. The variable is updated in the User variables section of the Environment Variables dialog box.

When you have finished creating or editing environment variables, click OK in the Environment Variables dialog box to save the values.

Windows 7

To open the Environment Variables dialog box:

  1. Click Start, then click Control Panel
  2. Click User Accounts.
  3. Click User Accounts again.
  4. In the Task side pane on the left, click Change my environment variables to open the Environment Variables dialog box opens.

To create a new environment variable:

  1. In the User variables section, click New to open the New User Variable dialog box.
  2. Enter the name of the variable and its value, and click OK. The variable is added to the User variables section of the Environment Variables dialog box.
  3. Click OK in the Environment Variables dialog box.

To modify an existing environment variable:

  1. In the User variables section, select the environment variable you want to modify.
  2. Click Edit to open the Edit User Variable dialog box opens.
  3. Change the value of the variable and click OK. The variable is updated in the User variables section of the Environment Variables dialog box.

When you have finished creating or editing environment variables, click OK in the Environment Variables dialog box to save the values. You can then close the Control Panel.

macOS

To set an environment variable on macOS, open a terminal window. If you are setting the environment variable to run jobs from the command line, use the following command:

export variable=value

where variable is the name of the environment variable (such as OFX_PLUGIN_PATH) and value is the value you want to assign to the variable, (such as /opt/OFX/Plugins). You can find out which environment variables have been set with the env command.

If you are setting the environment variable globally to use with applications, use the commands given below. The environment variables set by these commands are inherited by any shell or application.

macOS newer than 10.10

See this article for instructions on how to create a “plist” file to store system-wide environment variables in newer versions of macOS.

MacOS X 10.10

To set an environment variable, enter the following command:

launchctl setenv variable "value"

To find out if an environment variable is set, use the following command:

launchctl getenv variable

To clear an environment variable, use the following command:

launchctl unsetenv variable

Natron Environment Variables

NATRON_PLUGIN_PATH: A semicolon-separated list of directories where to look for PyPlugs and Toolsets. Subdirectories are also searched, and symbolic links are followed.

OFX_PLUGIN_PATH: A semicolon-separated list of directories where to look for OpenFX plugin bundles. Subdirectories are also searched, and symbolic links are followed.

PYTHONPATH: semicolon-separated list of directories where to look for extra python modules. The Python modules should be compatible with Natron’s embedded Python, and can be tested using the Python executable natron-python, which is installed next to the Natron binary. Python modules can also be installed with pip. For example, natron-python -m pip install numpy would install numpy for Natron.

OCIO: This variable can be used to point to the global OpenColorIO config file, e.g config.ocio, and it supersedes the OpenColorIO setting in Natron’s preferences.

FONTCONFIG_PATH: This variable may be used to override the default fontconfig configuration directory, which configures fonts used by Text plug-ins.

NATRON_DISK_CACHE_PATH: The location where the Natron tile/image cache is stored. This overrides the “Disk cache path” preference. On Linux, the default location is $XDG_CACHE_HOME/INRIA/Natron if the environment variable XDG_CACHE_HOME is set, else $HOME/.cache/INRIA/Natron. On macOS, the default location is $HOME/Library/Caches/INRIA/Natron. On Windows, the default location is C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\cache\INRIA\Natron.

Image nodes

The following sections contain documentation about every node in the Image group. Node groups are available by clicking on buttons in the left toolbar, or by right-clicking the mouse in the Node Graph area.

This documentation is for version 2.1 of OpenRaster (fr.inria.openfx.OpenRaster).

Description

Read OpenRaster image format.

Inputs
Input Description Optional
Sync Sync Yes
Controls
Parameter / script name Type Default Function
File / filename N/A   The input image sequence/video stream file(s).
First Frame / firstFrame Integer 0 The first frame number to read from this image sequence or video file. This cannot be less than the first frame of the image sequence or video file, and cannot be greater than the last frame of the image sequence or video file. The first frame of a video file is numbered 1. If startingTime is 1 or timeOffset is 0, this is also the first output frame.
Before / before Choice Hold
What to do before the first frame of the sequence.
Hold (hold): While before the sequence, load the first frame.
Loop (loop): Repeat the sequence before the first frame
Bounce (bounce): Repeat the sequence in reverse before the first frame
Black (black): Render a black image
Error (error): Report an error
Last Frame / lastFrame Integer 0 The last frame number to read from this image sequence or video file. This cannot be less than the first frame of the image sequence or video file, and cannot be greater than the last frame of the image sequence or video file. The first frame of a video file is numbered 1. If startingTime is 1 or timeOffset is 0, this is also the last output frame.
After / after Choice Hold
What to do after the last frame of the sequence.
Hold (hold): While before the sequence, load the first frame.
Loop (loop): Repeat the sequence before the first frame
Bounce (bounce): Repeat the sequence in reverse before the first frame
Black (black): Render a black image
Error (error): Report an error
On Missing Frame / onMissingFrame Choice Error
What to do when a frame is missing from the sequence/stream.
Hold previous (previous): Try to load the previous frame in the sequence/stream, if any.
Load next (next): Try to load the next frame in the sequence/stream, if any.
Load nearest (nearest): Try to load the nearest frame in the sequence/stream, if any.
Error (error): Report an error
Black (black): Render a black image
Frame Mode / frameMode Choice Starting Time

Starting Time (startingTime): Set at what output frame the first sequence frame is output. The sequence frame designated by the firstFrame parameter is output at frame timeOffset.
Time Offset (timeOffset): Set an offset to be applied as a number of frames. The sequence frame designated by the firstFrame parameter is output at frame firstFrame+timeOffset.
Starting Time / startingTime Integer 0 At what time (on the timeline) should this sequence/video start.
Time Offset / timeOffset Integer 0 Offset applied to the sequence in time units (i.e. frames).
Proxy File / proxy N/A   Filename of the proxy images. They will be used instead of the images read from the File parameter when the proxy mode (downscaling of the images) is activated.
Proxy threshold / proxyThreshold Double x: 1 y: 1 The scale of the proxy images. By default it will be automatically computed out of the images headers when you set the proxy file(s) path. When the render scale (proxy) is set to a scale lower or equal to this value then the proxy image files will be used instead of the original images. You can change this parameter by checking the “Custom scale” checkbox so that you can change the scale at which the proxy images should be used instead of the original images.
Custom Proxy Scale / customProxyScale Boolean Off Check to enable the Proxy scale edition.
File Premult / filePremult Choice PreMultiplied
The image file being read is considered to have this premultiplication state.
To get UnPremultiplied (or “unassociated alpha”) images, set the “Output Premult” parameter to Unpremultiplied.
By default the value should be correctly be guessed by the image file, but this parameter can be edited if the metadatas inside the file are wrong.
- Opaque means that the alpha channel is considered to be 1 (one), and it is not taken into account in colorspace conversion.
- Premultiplied, red, green and blue channels are divided by the alpha channel before applying the colorspace conversion, and re-multiplied by alpha after colorspace conversion.
- UnPremultiplied, means that red, green and blue channels are not modified before applying the colorspace conversion, and are multiplied by alpha after colorspace conversion.
This is set automatically from the image file and the plugin, but can be adjusted if this information is wrong in the file metadata.
RGB images can only be Opaque, and Alpha images can only be Premultiplied (the value of this parameter doesn’t matter).
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Premult / outputPremult Choice PreMultiplied
The alpha premultiplication in output of this node will have this state.
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Components / outputComponents Choice RGBA
What type of components this effect should output when the main color plane is requested. For the Read node it will map (in number of components) the Output Layer choice to these.
RGBA
Frame rate / frameRate Double 24 By default this value is guessed from the file. You can override it by checking the Custom fps parameter. The value of this parameter is what will be visible by the effects down-stream.
Custom FPS / customFps Boolean Off If checked, you can freely force the value of the frame rate parameter. The frame-rate is just the meta-data that will be passed downstream to the graph, no retime will actually take place.

ReadFFmpeg node

pluginIcon

This documentation is for version 1.0 of ReadFFmpeg (fr.inria.openfx.ReadFFmpeg).

Description

Read video using FFmpeg.

All formats supported by FFmpeg should be supported, but there may be issues with some non-conform files. In this case, it is recommended to transcode the video to a digital intermediate format, which is more suitable for grading, compositing and video editing.

This can be done using the ffmpeg command-line tool, by following the instructions at https://trac.ffmpeg.org/wiki/Encode/VFX

When the render scale (proxy) is set to a scale lower or equal to this value then the proxy image files will be used instead of the original images. You can change this parameter by checking the “Custom scale” checkbox so that you can change the scale at which the proxy images should be used instead of the original images.
Custom Proxy Scale / customProxyScale Boolean Off Check to enable the Proxy scale edition.
File Premult / filePremult Choice PreMultiplied
The image file being read is considered to have this premultiplication state.
To get UnPremultiplied (or “unassociated alpha”) images, set the “Output Premult” parameter to Unpremultiplied.
By default the value should be correctly be guessed by the image file, but this parameter can be edited if the metadatas inside the file are wrong.
- Opaque means that the alpha channel is considered to be 1 (one), and it is not taken into account in colorspace conversion.
- Premultiplied, red, green and blue channels are divided by the alpha channel before applying the colorspace conversion, and re-multiplied by alpha after colorspace conversion.
- UnPremultiplied, means that red, green and blue channels are not modified before applying the colorspace conversion, and are multiplied by alpha after colorspace conversion.
This is set automatically from the image file and the plugin, but can be adjusted if this information is wrong in the file metadata.
RGB images can only be Opaque, and Alpha images can only be Premultiplied (the value of this parameter doesn’t matter).
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Premult / outputPremult Choice PreMultiplied
The alpha premultiplication in output of this node will have this state.
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Components / outputComponents Choice RGBA
What type of components this effect should output when the main color plane is requested. For the Read node it will map (in number of components) the Output Layer choice to these.
RGBA
RGB
Frame rate / frameRate Double 24 By default this value is guessed from the file. You can override it by checking the Custom fps parameter. The value of this parameter is what will be visible by the effects down-stream.
Custom FPS / customFps Boolean Off If checked, you can freely force the value of the frame rate parameter. The frame-rate is just the meta-data that will be passed downstream to the graph, no retime will actually take place.
Max retries per frame / maxRetries Integer 10 Some video files are sometimes tricky to read and needs several retries before successfully decoding a frame. This parameter controls how many times we should attempt to decode the same frame before failing.
First Track Only / firstTrackOnly Boolean Off Causes the reader to ignore all but the first video track it finds in the file. This should be selected in a multiview project if the file happens to contain multiple video tracks that don’t correspond to different views.

This is set automatically from the image file and the plugin, but can be adjusted if this information is wrong in the file metadata.
RGB images can only be Opaque, and Alpha images can only be Premultiplied (the value of this parameter doesn’t matter).
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.

Frame rate / frameRate Double 24 By default this value is guessed from the file. You can override it by checking the Custom fps parameter. The value of this parameter is what will be visible by the effects down-stream.
Custom FPS / customFps Boolean Off If checked, you can freely force the value of the frame rate parameter. The frame-rate is just the meta-data that will be passed downstream to the graph, no retime will actually take place.
Image Info… / showMetadata Button   Shows information and metadata from the image at current time.
Auto Bright / rawAutoBright Boolean Off If checked, use libraw’s automatic increase of brightness by histogram (exposure correction).
Use Camera WB / rawUseCameraWB Boolean On If checked, and if possible, use the white balance from the camera.
Adjust Maximum Thr. / rawAdjustMaximumThr Double 0
This parameters controls auto-adjusting of maximum value based on channel_maximum[] data, calculated from real frame data. If calculated maximum is greater than adjust_maximum_thr*maximum, than maximum is set to calculated_maximum.
Default: 0. If you set this value above 0.99999, then default value will be used. If you set this value below 0.00001, then no maximum adjustment will be performed. A value of 0.75 is reasonable for still shots, but sequences should always use 0.
Adjusting maximum should not damage any picture (esp. if you use default value) and is very useful for correcting channel overflow problems (magenta clouds on landscape shots, green-blue highlights for indoor shots).
Max. value / rawUserSat Integer 0 The camera sensor saturation (maximum) value. Raw values greater or equal to this are considered saturated and are processed using the algorithm specified by the rawHighlightMode parameter. 0 means to use the default value.

Algorithm for restoring highlight clippings. Highlights are part of your images that are burned due to the inability of your camera to capture the highlights. Highlight recovery is applied after white balance and demosaic.
Clip (clip): Clip all highlights to white.
Unclip (unclip): Leave highlights unclipped in various shades of pink.
Blend (blend): Blend clipped and unclipped values for a gradual fade to white.
Rebuild (rebuild): Reconstruct highlights with various levels of aggressiveness.
Rebuild Level / rawHighlightRebuildLevel Integer 2 Level of aggressiveness used to rebuild highlights. rawHighlightRebuildLevel=2 (which corresponds to -H 5 in LibRaw/dcraw) is a good compromise. If that’s not good enough, use rawHighlightRebuildLevel=6, cut out the non-white highlights, and paste them into an image generated with rawHighlightRebuildLevel=0.
Exposure / rawExposure Double 1 Amount of exposure correction before de-mosaicing, from 0.25 (2-stop darken) to 8 (3-stop brighten). (Default: 1., meaning no correction.)
Demosaic / rawDemosaic Choice AHD
Force a demosaicing algorithm. Will fall back on AHD if the demosaicing algorithm is not available due to licence restrictions (AHD-Mod, AFD, VCD, Mixed, LMMSE are GPL2, AMaZE is GPL3).
None (none): No demosaicing.
Linear (linear): Linear interpolation.
VNG (vng): VNG interpolation.
PPG (ppg): PPG interpolation.
AHD (ahd): AHD interpolation.
DCB (dcb): DCB interpolation.
AHD-Mod (ahdmod): Modified AHD interpolation by Paul Lee.
AFD (afd): AFD interpolation (5-pass).
VCD (vcd): VCD interpolation.
Mixed (mixed): Mixed VCD/Modified AHD interpolation.
LMMSE (lmmse): LMMSE interpolation.
DHT (dht): DHT interpolation.
AAHD (aahd): Modified AHD interpolation by Anton Petrusevich.
Aber. / rawAber Double x: 1 y: 1 Correction of chromatic aberrations, given as a red multiplier and a blue multiplier. The default values of (1.,1.) correspond to no correction.
Output Layer / outputLayer Choice   This is the layer that will be set to the the color plane. This is relevant only for image formats that can have multiple layers: exr, tiff, psd, etc… Note that in Natron you can access other layers with a Shuffle node downstream of this node.
Edge Pixels / edgePixels Choice Auto
Specifies how pixels in the border of the region of definition are handled
Auto (auto): If the region of definition and format match exactly then repeat the border pixel otherwise use black
Edge Detect (edge): For each edge, if the region of definition and format match exactly then repeat border pixel, otherwise use black
Repeat (repeat): Repeat pixels outside the region of definition
Black (black): Add black pixels outside the region of definition
Offset Negative Display Window / offsetNegativeDispWindow Boolean On The EXR file format can have its “display window” origin at another location than (0,0). However in OpenFX, formats should have their origin at (0,0). If the left edge of the display window is not 0, either you can offset the display window so it goes to 0, or you can treat the negative portion as overscan and resize the format.

This documentation is for version 1.4 of ReadPDF (fr.inria.openfx.ReadPDF).

Description

Read PDF documents using poppler.

Inputs
Input Description Optional
Sync Sync Yes
Controls
Parameter / script name Type Default Function
File / filename N/A   The input image sequence/video stream file(s).
First Frame / firstFrame Integer 0 The first frame number to read from this image sequence or video file. This cannot be less than the first frame of the image sequence or video file, and cannot be greater than the last frame of the image sequence or video file. The first frame of a video file is numbered 1. If startingTime is 1 or timeOffset is 0, this is also the first output frame.
Before / before Choice Hold
What to do before the first frame of the sequence.
Hold (hold): While before the sequence, load the first frame.
Loop (loop): Repeat the sequence before the first frame
Bounce (bounce): Repeat the sequence in reverse before the first frame
Black (black): Render a black image
Error (error): Report an error
Last Frame / lastFrame Integer 0 The last frame number to read from this image sequence or video file. This cannot be less than the first frame of the image sequence or video file, and cannot be greater than the last frame of the image sequence or video file. The first frame of a video file is numbered 1. If startingTime is 1 or timeOffset is 0, this is also the last output frame.
After / after Choice Hold
What to do after the last frame of the sequence.
Hold (hold): While before the sequence, load the first frame.
Loop (loop): Repeat the sequence before the first frame
Bounce (bounce): Repeat the sequence in reverse before the first frame
Black (black): Render a black image
Error (error): Report an error
On Missing Frame / onMissingFrame Choice Error
What to do when a frame is missing from the sequence/stream.
Hold previous (previous): Try to load the previous frame in the sequence/stream, if any.
Load next (next): Try to load the next frame in the sequence/stream, if any.
Load nearest (nearest): Try to load the nearest frame in the sequence/stream, if any.
Error (error): Report an error
Black (black): Render a black image
Frame Mode / frameMode Choice Starting Time

Starting Time (startingTime): Set at what output frame the first sequence frame is output. The sequence frame designated by the firstFrame parameter is output at frame timeOffset.
Time Offset (timeOffset): Set an offset to be applied as a number of frames. The sequence frame designated by the firstFrame parameter is output at frame firstFrame+timeOffset.
Starting Time / startingTime Integer 0 At what time (on the timeline) should this sequence/video start.
Time Offset / timeOffset Integer 0 Offset applied to the sequence in time units (i.e. frames).
Proxy File / proxy N/A   Filename of the proxy images. They will be used instead of the images read from the File parameter when the proxy mode (downscaling of the images) is activated.
Proxy threshold / proxyThreshold Double x: 1 y: 1 The scale of the proxy images. By default it will be automatically computed out of the images headers when you set the proxy file(s) path. When the render scale (proxy) is set to a scale lower or equal to this value then the proxy image files will be used instead of the original images. You can change this parameter by checking the “Custom scale” checkbox so that you can change the scale at which the proxy images should be used instead of the original images.
Custom Proxy Scale / customProxyScale Boolean Off Check to enable the Proxy scale edition.
File Premult / filePremult Choice PreMultiplied
The image file being read is considered to have this premultiplication state.
To get UnPremultiplied (or “unassociated alpha”) images, set the “Output Premult” parameter to Unpremultiplied.
By default the value should be correctly be guessed by the image file, but this parameter can be edited if the metadatas inside the file are wrong.
- Opaque means that the alpha channel is considered to be 1 (one), and it is not taken into account in colorspace conversion.
- Premultiplied, red, green and blue channels are divided by the alpha channel before applying the colorspace conversion, and re-multiplied by alpha after colorspace conversion.
- UnPremultiplied, means that red, green and blue channels are not modified before applying the colorspace conversion, and are multiplied by alpha after colorspace conversion.
This is set automatically from the image file and the plugin, but can be adjusted if this information is wrong in the file metadata.
RGB images can only be Opaque, and Alpha images can only be Premultiplied (the value of this parameter doesn’t matter).
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Premult / outputPremult Choice PreMultiplied
The alpha premultiplication in output of this node will have this state.
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Components / outputComponents Choice RGBA
What type of components this effect should output when the main color plane is requested. For the Read node it will map (in number of components) the Output Layer choice to these.
RGBA
Frame rate / frameRate Double 24 By default this value is guessed from the file. You can override it by checking the Custom fps parameter. The value of this parameter is what will be visible by the effects down-stream.
Custom FPS / customFps Boolean Off If checked, you can freely force the value of the frame rate parameter. The frame-rate is just the meta-data that will be passed downstream to the graph, no retime will actually take place.
DPI / dpi Double 150 Dots-per-inch (150 is default)

Loop (loop): Repeat the sequence before the first frame
Bounce (bounce): Repeat the sequence in reverse before the first frame
Black (black): Render a black image
Error (error): Report an error
Last Frame / lastFrame Integer 0 The last frame number to read from this image sequence or video file. This cannot be less than the first frame of the image sequence or video file, and cannot be greater than the last frame of the image sequence or video file. The first frame of a video file is numbered 1. If startingTime is 1 or timeOffset is 0, this is also the last output frame.
After / after Choice Hold
What to do after the last frame of the sequence.
Hold (hold): While before the sequence, load the first frame.
Loop (loop): Repeat the sequence before the first frame
Bounce (bounce): Repeat the sequence in reverse before the first frame
Black (black): Render a black image
Error (error): Report an error
On Missing Frame / onMissingFrame Choice Error
What to do when a frame is missing from the sequence/stream.
Hold previous (previous): Try to load the previous frame in the sequence/stream, if any.
Load next (next): Try to load the next frame in the sequence/stream, if any.
Load nearest (nearest): Try to load the nearest frame in the sequence/stream, if any.
Error (error): Report an error
Black (black): Render a black image
Frame Mode / frameMode Choice Starting Time

Starting Time (startingTime): Set at what output frame the first sequence frame is output. The sequence frame designated by the firstFrame parameter is output at frame timeOffset.
Time Offset (timeOffset): Set an offset to be applied as a number of frames. The sequence frame designated by the firstFrame parameter is output at frame firstFrame+timeOffset.
Starting Time / startingTime Integer 0 At what time (on the timeline) should this sequence/video start.
Time Offset / timeOffset Integer 0 Offset applied to the sequence in time units (i.e. frames).
Proxy File / proxy N/A   Filename of the proxy images. They will be used instead of the images read from the File parameter when the proxy mode (downscaling of the images) is activated.
Proxy threshold / proxyThreshold Double x: 1 y: 1 The scale of the proxy images. By default it will be automatically computed out of the images headers when you set the proxy file(s) path. When the render scale (proxy) is set to a scale lower or equal to this value then the proxy image files will be used instead of the original images. You can change this parameter by checking the “Custom scale” checkbox so that you can change the scale at which the proxy images should be used instead of the original images.
Custom Proxy Scale / customProxyScale Boolean Off Check to enable the Proxy scale edition.
File Premult / filePremult Choice PreMultiplied
The image file being read is considered to have this premultiplication state.
To get UnPremultiplied (or “unassociated alpha”) images, set the “Output Premult” parameter to Unpremultiplied.
By default the value should be correctly be guessed by the image file, but this parameter can be edited if the metadatas inside the file are wrong.
- Opaque means that the alpha channel is considered to be 1 (one), and it is not taken into account in colorspace conversion.
- Premultiplied, red, green and blue channels are divided by the alpha channel before applying the colorspace conversion, and re-multiplied by alpha after colorspace conversion.
- UnPremultiplied, means that red, green and blue channels are not modified before applying the colorspace conversion, and are multiplied by alpha after colorspace conversion.
This is set automatically from the image file and the plugin, but can be adjusted if this information is wrong in the file metadata.
RGB images can only be Opaque, and Alpha images can only be Premultiplied (the value of this parameter doesn’t matter).
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Premult / outputPremult Choice PreMultiplied
The alpha premultiplication in output of this node will have this state.
Opaque (opaque): The image is opaque and so has no premultiplication state, as if the alpha component in all pixels were set to the white point.
PreMultiplied (premult): The image is premultiplied by its alpha (also called “associated alpha”).
UnPreMultiplied (unpremult): The image is unpremultiplied (also called “unassociated alpha”).
Output Components / outputComponents Choice RGBA
What type of components this effect should output when the main color plane is requested. For the Read node it will map (in number of components) the Output Layer choice to these.
RGBA
Frame rate / frameRate Double 24 By default this value is guessed from the file. You can override it by checking the Custom fps parameter. The value of this parameter is what will be visible by the effects down-stream.
Custom FPS / customFps Boolean Off If checked, you can freely force the value of the frame rate parameter. The frame-rate is just the meta-data that will be passed downstream to the graph, no retime will actually take place.

RunScript node

pluginIcon

This documentation is for version 1.0 of RunScript (fr.inria.openfx.RunScript).

Description

Run a script with the given arguments. This is mostly useful to execute an external program on a set of input images files, which outputs image files. Writers should be connected to each input, so that the image files are written before running the script, and the output of this node should be fed into one or more Readers, which read the images written by the script.

Sample section of a node graph which uses RunScript:

              ...
               ^
               |
Write([Project]/scriptinput#####.png)
               ^
               |
RunScript1(processes [Project]/scriptinput#####.png, output is [Project]/scriptoutput#####.png)
               ^
               |
Read([Project]/scriptoutput#####.png, set the frame range manually)
               ^
               |
RunScript2(deletes temporary files [Project]/scriptinput#####.png and [Project]/scriptoutput#####.png, optional)
               ^
               |
              ...

Keep in mind that the input and output files are never removed in the above graph. The output of RunScript is a copy of its first input.

Each argument may be:

  • A filename (RunScript1 and RunScript2 in the example above should have [Project]/scriptinput#####.png and [Project]/scriptoutput#####.png as filename parameters 1 and 2)
  • A floating-point value (which can be linked to any plugin)
  • An integer
  • A string

Under Unix, the script should begin with a traditional shebang line, e.g. ‘#!/bin/sh’ or ‘#!/usr/bin/env python’ The arguments can be accessed as usual from the script (in a Unix shell-script, argument 1 would be accessed as “$1” - use double quotes to avoid problems with spaces). For example, the script in RunScript2 in the above example would be:

#!/bin/sh
rm "$1" "$2"

WriteFFmpeg node

pluginIcon

This documentation is for version 1.0 of WriteFFmpeg (fr.inria.openfx.WriteFFmpeg).

Description

Write a video sequence using FFmpeg.

This plugin can be used to produce entheir digital intermediates, i.e. videos with very high resolution and quality which can be read frame by frame for further processing, or highly compressed videos to distribute on the web. Note that this plug-in does not support audio, but audi can easily be added to the video using the ffmpeg command-line tool (see note below). In a VFX context, it is often preferable to save processed images as a sequence of individual frames (using WriteOIIO), if disk space and real-time playing are not an issue.

The preferred pixel coding (Pref. Pixel Coding) and bit depth (Pref. Bit Depth) can be selected. This is especially useful for codecs that propose multiple pixel formats (e.g. ffv1, ffvhuff, huffyuv, jpeg2000, mjpeg, mpeg2video, vc2, libopenjpeg, png, qtrle, targa, tiff, libschroedinger, libtheora, libvpx, libvpx-vp9, libx264, libx265).

The pixel format is selected from the available choices for the chosen codec using the following rules:

  • First, try to find the format with the smallest BPP (bits per pixel) that fits into the preferences.
  • Second, If no format fits, get the format that has a BPP equal or a bit higher that the one computed from the preferences.
  • Last, if no such format is found, get the format that has the highest BPP.

The selected pixel coding, bit depth, and BPP are displayed in the Selected Pixel Coding, Bit Depth, and BPP parameters.

The recommended Codec/Container configurations for encoding digital intermediates are (see also https://trac.ffmpeg.org/wiki/Encode/VFX):

  • ProRes inside QuickTime: all ProRes profiles are 10-bit and are intra-frame (each frame is encoded separately). Prores 4444 can also encode the alpha channel.
  • Avid DNxHR inside QuickTime: the codec is intra-frame. DNxHR profiles are resolution-independent and are available with 8-bit or 10-bit depth. The alpha channel cannot be encoded.
  • HEVC (hev1/libx265) inside Matroska, MP4, QuickTime or MPEG-TS and Output Quality set to Lossless or Perceptually Lossless. libx265 supports 8-bit, 10-bit and 12-bit depth (if libx265 was compiled with high bit depth support). Lossless may not be playable in real-time for high resolutions. Set the Encoding Speed to Ultra Fast for faster encoding but worse compression, or Very Slow for best compression.

To write videos intended for distribution (as media files or for streaming), the most popular codecs are mp4v (mpeg4 or libxvid), avc1 (libx264), H264 (libopenh264), hev1 (libx265), VP80 (libvpx) and VP90 (libvpx-vp9). The quality of mp4v may be set using the Global Quality parameter (between 1 and 31, 1 being the highest quality), and the quality of avc1, hev1, VP80 and VP90 may be set using the Output Quality parameter. More information can be found at https://trac.ffmpeg.org/wiki#Encoding

If the output video should be encoded with specific FFmpeg options, such as a given pixel format or encoding option, it is better to write the output as individual frames in an image format that has a sufficient bit depth, and to encode the set of individual frames to a video using the command-line ffmpeg tool.

The settings for the “Global Quality” and “Quality” parameters may have different meanings for different codecs. See http://slhck.info/video/2017/02/24/vbr-settings.html for a summary of recommended values. Using these settings should be preferred over constant bitrate-based encoding, as it usually gives a much better result.

Adding audio

If synchronized audio is available as a separate file, encoded with the right codec, it can be easily added to the video using a command like: ffmpeg -i input.mp4 -i input.mp3 -c copy -map 0:0 -map 1:0 output.mp4 (in this example, input.mp4 contains the video, input.mp3 contains the audio, and output.mp4 co,ntains both tracks).

This command does not re-encode the video or audio, but simply copies the data from each source file and places it in separate streams in the output.

BPP / infoBpp Integer 0 Bits per pixel of the pixel format.
DNxHD Output Range / DNxHDEncodeVideoRange Choice Video Range
When encoding using DNxHD this is used to select between full scale data range and ‘video/legal’ data range.
Full scale data range is 0-255 for 8-bit and 0-1023 for 10-bit. ‘Video/legal’ data range is a reduced range, 16-240 for 8-bit and 64-960 for 10-bit.
Full Range (full)
Video Range (video)
Output Quality / crf Choice Medium Quality
Constant Rate Factor (CRF); tradeoff between video quality and file size. Used by avc1, hev1, VP80, VP9, and CAVS codecs.
Option -crf in ffmpeg.
None (none): Use constant bit-rate rather than constant output quality
Lossless (crf0): Corresponds to CRF = 0.
Perceptually Lossless (crf17): Corresponds to CRF = 17.
High Quality (crf20): Corresponds to CRF = 20.
Medium Quality (crf23): Corresponds to CRF = 23.
Low Quality (crf26): Corresponds to CRF = 26.
Very Low Quality (crf29): Corresponds to CRF = 29.
Encoding Speed / x26xSpeed Choice Medium
Trade off performance for compression efficiency. Available for avc1 and hev1.
Option -preset in ffmpeg.
Ultra Fast (ultrafast): Fast encoding, but larger file size.
Very Fast (veryfast)
Faster (faster)
Fast (fast)
Medium (medium)
Slow (slow)
Slower (slower)
Very Slow (veryslow): Slow encoding, but smaller file size.
Global Quality / qscale Double -1
For lossy encoding, this controls image quality, from 0 to 100 (the lower, the better, 0 being near-lossless). For lossless encoding, this controls the effort and time spent at compressing more. -1 or negative value means to use the codec default or CBR (constant bit rate). Used for example by FLV1, mjp2, theo, jpeg, m2v1, mp4v MP42, 3IVD, codecs.
Option -qscale in ffmpeg.
Quality / quality Integer min: -1 max: -1
The quality range the codec is allowed to vary the image data quantiser between to attempt to hit the desired bitrate. The lower, the better: higher values mean increased image degradation is possible, but with the upside of lower bit rates. Only supported by certain codecs (e.g. VP80, VP90, avc1, but not hev1 or mp4v).
-1 means to use the codec default.
Options -qmin and -qmax in ffmpeg.
Bitrate / bitrateMbps Double 185
The target bitrate the codec will attempt to reach (in Megabits/s), within the confines of the bitrate tolerance and quality min/max settings. Only supported by certain codecs (e.g. hev1, m2v1, MP42, 3IVD, but not mp4v, avc1 or H264).
Option -b in ffmpeg (multiplied by 1000000).
Bitrate Tolerance / bitrateToleranceMbps Double 0
Set video bitrate tolerance (in Megabits/s). In 1-pass mode, bitrate tolerance specifies how far ratecontrol is willing to deviate from the target average bitrate value. This is not related to min/max bitrate. Lowering tolerance too much has an adverse effect on quality. As a guideline, the minimum slider range of target bitrate/target fps is the lowest advisable setting. Anything below this value may result in failed renders.
Only supported by certain codecs (e.g. MP42, 3IVD, but not avc1, hev1, m2v1, mp4v or H264).
A reasonable value is 5 * bitrateMbps / fps.
Option -bt in ffmpeg (multiplied by 1000000).
Keyframe Interval / gopSize Integer -1
The keyframe intervale, also called GOP size, specifies how many frames may be grouped together by the codec to form a compression GOP. Exercise caution with this control as it may impact whether the resultant file can be opened in other packages. Only supported by certain codecs.
-1 means to use the codec default if bFrames is not 0, or 1 if bFrames is 0 to ensure only intra (I) frames are produced, producing a video which is easier to scrub frame-by-frame.
Option -g in ffmpeg.
Max B-Frames / bFrames Integer -1
Set max number of B frames between non-B-frames. Must be an integer between -1 and 16. 0 means that B-frames are disabled. If a value of -1 is used, it will choose an automatic value depending on the encoder. Influences file size and seekability. Only supported by certain codecs.
-1 means to use the codec default if Keyframe Interval is not 1, or 0 if Keyframe Interval is 1 to ensure only intra (I) frames are produced, producing a video which is easier to scrub frame-by-frame.
Option -bf in ffmpeg.
Write NCLC / writeNCLC Boolean On Write nclc data in the colr atom of the video header. QuickTime only.

Quality / quality Integer 100 Indicates the quality of compression to use (0-100), for those plugins and compression methods that allow a variable amount of compression, with higher numbers indicating higher image fidelity. [JPEG, TIFF w/ JPEG comp., WEBP]
DWA Compression Level / dwaCompressionLevel Double 45 Amount of compression when using Dreamworks DWAA or DWAB compression options. These lossy formats are variable in quality and can minimize the compression artifacts. Higher values will result in greater compression and likewise smaller file size, but increases the chance for artifacts. Values from 45 to 150 are usually correct for production shots, whereas HDR vacation photos could use up to 500. Values below 45 should give no visible imprrovement on photographs. [EXR w/ DWAa or DWAb comp.]
Orientation / orientation Choice normal
The orientation of the image data [DPX,TIFF,JPEG,HDR,FITS].
By default, image pixels are ordered from the top of the display to the bottom, and within each scanline, from left to right (i.e., the same ordering as English text and scan progression on a CRT). But the “Orientation” parameter can suggest that it should be displayed with a different orientation, according to the TIFF/EXIF conventions.
normal: normal (top to bottom, left to right)
flop: flipped horizontally (top to bottom, right to left)
180: rotate 180deg (bottom to top, right to left)

90counter-clockwise: rotated 90deg counter-clockwise (left to right, bottom to top)
Compression / compression Choice default
Compression type [TIFF,EXR,DDS,IFF,SGI,TGA]
Indicates the type of compression the file uses. Supported compression modes will vary from format to format. As an example, the TIFF format supports “none”, “lzw”, “ccittrle”, “zip” (the default), “jpeg”, “packbits”, and the EXR format supports “none”, “rle”, “zip” (the default), “piz”, “pxr24”, “b44”, “b44a”, “dwaa” or “dwab”.
default: Guess from the output format
none: No compression [EXR, TIFF, IFF]
zip: Zlib/Deflate compression (lossless) [EXR, TIFF, Zfile]
zips: Zlib compression (lossless), one scan line at a time [EXR]
rle: Run Length Encoding (lossless) [DPX, IFF, EXR, TGA, RLA]
piz: Piz-based wavelet compression [EXR]
pxr24: Lossy 24bit float compression [EXR]
b44: Lossy 4-by-4 pixel block compression, fixed compression rate [EXR]
b44a: Lossy 4-by-4 pixel block compression, flat fields are compressed more [EXR]
dwaa: lossy DCT based compression, in blocks of 32 scanlines. More efficient for partial buffer access. [EXR]
dwab: lossy DCT based compression, in blocks of 256 scanlines. More efficient space wise and faster to decode full frames than DWAA. [EXR]
lzw: Lempel-Ziv Welsch compression (lossless) [TIFF]
ccittrle: CCITT modified Huffman RLE (lossless) [TIFF]
jpeg: JPEG [TIFF]
packbits: Macintosh RLE (lossless) [TIFF]
Layer(s) / outputChannels Choice Color.RGBA
Select which layer to write to the file. This is either All or a single layer. This is not yet possible to append a layer to an existing file.

DisparityRight.Disparity (uk.co.thefoundry.OfxImagePlaneStereoDisparityRight)
Backward.Motion (uk.co.thefoundry.OfxImagePlaneBackMotionVector)
Forward.Motion (uk.co.thefoundry.OfxImagePlaneForwardMotionVector)
All Planes / processAllPlanes Boolean Off When checked all planes in input will be processed and output to the same plane as in input. It is useful for example to apply a Transform effect on all planes.
Parts / partSplitting Choice Split Views,Layers
Defines whether to separate views/layers in different EXR parts or not. Note that multi-part files are only supported by OpenEXR >= 2
Single Part (single): All views and layers will be in the same part, ensuring compatibility with OpenEXR 1.x
Split Views (views): All views will have its own part, and each part will contain all layers. This will produce an EXR optimized in size that can be opened only with applications supporting OpenEXR 2
Split Views,Layers (views_layers): Each layer of each view will have its own part. This will produce an EXR optimized for decoding speed that can be opened only with applications supporting OpenEXR 2
Views / viewsSelector Choice All
Select the views to render. When choosing All, make sure the output filename does not have a %v or %V view pattern in which case each view would be written to a separate file.

File / filename N/A   The output image sequence/video stream file(s). The string must match the following format: path/sequenceName###.ext where the number of # (hashes) will define the number of digits to append to each file. For example path/mySequence###.jpg will be translated to path/mySequence000.jpg, path/mySequence001.jpg, etc. %d printf-like notation can also be used instead of the hashes, for example path/sequenceName%03d.ext will achieve the same than the example aforementioned. there will be at least 2 digits).

Compression / compression Choice Default
Compression used by the internal zlib library when encoding the file. This parameter is used to tune the compression algorithm.
Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of Filtered is to force more Huffman coding and less string matching; it is somewhat intermediate between Default and Huffman Only. RLE is designed to be almost as fast as Huffman Only, but give better compression for PNG image data. The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately. Fixed prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications.
Default (default): Use this for normal data
Filtered (filtered): Use this for data produced by a filter (or predictor)
Huffman Only (huffman): Forces Huffman encoding only (nostring match)
RLE (rle): Limit match distances to one (run-length encoding)
Fixed (fixed): Prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications
Compression Level / compressionLevel Integer 6
Between 0 and 9:
1 gives best speed, 9 gives best compression, 0 gives no compression at all (the input data is simply copied a block at a time). Default compromise between speed and compression is 6.
Depth / bitDepth Choice 8-bit
The depth of the internal PNG. Only 8bit and 16bit are supported by this writer
8-bit (8u)
16-bit (16u)
Dithering / enableDithering Boolean On When checked, conversion from float input buffers to 8-bit PNG will use a dithering algorithm to reduce quantization artifacts. This has no effect when writing to 16bit PNG

Draw nodes

The following sections contain documentation about every node in the Draw group. Node groups are available by clicking on buttons in the left toolbar, or by right-clicking the mouse in the Node Graph area.

LightWrap node

pluginIcon

This documentation is for version 1.0 of LightWrap (fr.inria.LightWrap).

Description

LightWrap helps composite objects onto a bright background by simulating reflections from the background light on the foreground, around its edges. Input A is the foreground image and its matte, and input B the the background to use for the wrapping effect.

The output of LightWrap should then be composited over the background to give the final composite.

Inputs
Input Description Optional
A   No
B   No
Controls
Parameter / script name Type Default Function
Convert to Group / convertToGroup Button   Converts this node to a Group: the internal node-graph and the user parameters will become editable
Diffuse / diffuse Double x: 15 y: 15 Size of the reflections from the background to the foreground element (Intensity controls their intensity). Start by setting Diffuse to zero and adjust intensity to see what colors from the background are being reflected. Then adjust Diffuse, come back to Intensity if necessary, and balance both parameters until the result is satisfactory.
Intensity / intensity Double 0 Brightness of the reflections from the background to the foreground element (Diffuse controls their size). Start by setting Diffuse to zero and adjust intensity to see what colors from the background are being reflected. Then adjust Diffuse, come back to Intensity if necessary, and balance both parameters until the result is satisfactory.
Generate Wrap Only / onlyWrap Boolean Off When checked, the LightWrap in generated but is not merged with the foreground object (disables the Highlight Merge).
Disable luminance-Based Wrap / disableLuma Boolean Off When checked, the LightWrap effect is created uniformly around the edged, rather than being controled by the color of the background.
Enable Glow / enableGlow Boolean Off When checked, the LightWrap is not masked by the foreground object, so that the objects seems to glow.
FGBlur / fgblur Double x: 1 y: 1 Size of the blur applied to the alpha channel of the foreground (i.e. the foreground matte). More blur causes more background to be added to the foreground.
FGBlur Border Conditions / fgblurBoundary Choice Black
Border conditions of the blur applied to the alpha channel of the foreground (i.e. the foreground matte). Use “Black” in most cases, and “Nearest” if the foreground matte should be extended beyond image borders when it touches them.
Black (black): Dirichlet boundary condition: pixel values out of the image domain are zero.
Nearest (nearest): Neumann boundary condition: pixel values out of the image domain are those of the closest pixel location in the image domain.
BGBlur / bgblur Double x: 0 y: 0 Size of the blur applied to the background before merging it with the foreground element and applying the Diffuse blur.
Saturation / saturation Double 1 Color saturation of the LightWrap effect. Advanced color correction parameters are available in the ColorCorrect tab.
Luma Tolerance / lumaTolerance Double 0 Luminance threshold of the LightWrap effect. Luminance values below this do not generate a LightWrap.
Highlight Merge / highlightmerge Choice plus
Merge operation between the foreground object and the background. The default operation is “plus”, which produces a glow effect.

Rectangle node

pluginIcon

This documentation is for version 2.1 of Rectangle (net.sf.openfx.Rectangle).

Description

Draw a rectangle.

The rectangle is composited with the source image using the ‘over’ operator.

If no source is connected, this effect behaves like a generator. Its region of definition is:

  • The selected format if the Extent parameter is a format.
  • The project output format if Color0 is not black and transparent.
  • The selected extent plus a one-pixel border if Color0 is black and transparent.

SeGrain node

This documentation is for version 1.0 of SeGrain (net.sf.openfx.SeGrain).

Description

Adds synthetic grain.

Push “presets” to get predefined types of grain, these are the correct size for 2K scans.

You can also adjust the sliders to match a sample piece of grain. Find a sample with a rather constant background, blur it to remove the grain, and use as input to this. View with a wipe in the viewer so you can make a match. It helps to view and match each of the red, green, blue separately.

Controls
Parameter / script name Type Default Function
Replace / replace Boolean Off Clear the selected channel(s) before drawing into them.
Noise Size / noiseSize Double x: 350 y: 350 Size of noise in pixels, corresponding to its lowest frequency.
Z0 / noiseZ Double 0 Z coordinate on the noise at frame=0. The noise pattern is different for every integer value of Z, so this can be used as a random seed.
Z Slope / noiseZSlope Double 0 Z is computed as Z = Z0 + frame * Z_slope. 0 means a constant noise, 1 means a different noise pattern at every frame.
Noise Type / noiseType Choice FBM
Kind of noise.
Cell Noise (cell): Cell noise generates a field of constant colored cubes based on the integer location. This is the same as the prman cellnoise function. You may want to set xRotate and yRotate to 0 in the Transform tab to get square cells.
Noise (noise): Noise is a random function that smoothly blends between samples at integer locations. This is Ken Perlin’s original noise function.
FBM (fbm): FBM (Fractal Brownian Motion) is a multi-frequency noise function. The base frequency is the same as the “Noise” function. The total number of frequencies is controlled by octaves. The lacunarity is the spacing between the frequencies - a value of 2 means each octave is twice the previous frequency. The gain controls how much each frequency is scaled relative to the previous frequency.
Turbulence (turbulence): turbulence is a variant of fbm where the absolute value of each noise term is taken. This gives a more billowy appearance.
Voronoi (voronoi): Voronoi is a cellular noise pattern. It is a jittered variant of cellnoise. The type parameter describes different variants of the noise function. The jitter param controls how irregular the pattern is (jitter = 0 is like ordinary cellnoise). The fbm* params can be used to distort the noise field. When fbmScale is zero (the default), there is no distortion. The remaining params are the same as for the fbm function. NOTE: This does not necessarily return [0,1] value, because it can return arbitrary distance.
Voronoi Type / voronoiType Choice Cell
Different variants of the Voronoi noise function.
Cell (cell)

Type 3 (type3)
Type 4 (type4)
Type 5 (type5)

FBM Scale / fbmScale Double 0 The fbm* params can be used to distort the noise field. When fbmScale is zero (the default), there is no distortion.
Octaves / fbmOctaves Integer 6 The total number of frequencies is controlled by octaves.
Lacunarity / fbmLacunarity Double 2 The lacunarity is the spacing between the frequencies - a value of 2 means each octave is twice the previous frequency.
Gain / fbmGain Double 0.5 The gain controls how much each frequency is scaled relative to the previous frequency.

Deinterlace node

pluginIcon

This documentation is for version 1.0 of Deinterlace (net.sf.openfx.Deinterlace).

Description

Deinterlace input stream.

The following deinterlacing algorithms are supported:

  • Weave: This is what 100fps.com calls “do nothing”. Other names: “disabled” or “no deinterlacing”. Should be used for PsF content.
  • Blend: Blender (full resolution). Each line of the picture is created as the average of a line from the odd and a line from the even half-pictures. This ignores the fact that they are supposed to be displayed at different times.
  • Bob: Doubler. Display each half-picture like a full picture, by simply displaying each line twice. Preserves temporal resolution of interlaced video.
  • Discard: Only display one of the half-pictures, discard the other. Other name: “single field”. Both temporal and vertical spatial resolutions are halved. Can be used for slower computers or to give interlaced video movie-like look with characteristic judder.
  • Linear: Doubler. Bob with linear interpolation: instead of displaying each line twice, line 2 is created as the average of line 1 and 3, etc.
  • Mean: Blender (half resolution). Display a half-picture that is created as the average of the two original half-pictures.
  • Yadif: Interpolator (Yet Another DeInterlacing Filter) from MPlayer by Michael Niedermayer (http://www.mplayerhq.hu). It checks pixels of previous, current and next frames to re-create the missed field by some local adaptive method (edge-directed interpolation) and uses spatial check to prevent most artifacts.

Inputs
Input Description Optional
Source   No
Controls
Parameter / script name Type Default Function
Reverse input / reverseInput Boolean Off Reverse the order of the input frames so that last one is first
Speed / speed Double 1 How much to change the speed of the input clip. To determine which input frame is taken at a given time, the speed is integrated from the beginning of the source frame range to the given time, so that speed can be animated to locally accelerate (speed > 1), decelerate (speed < 1) or reverse (speed < 0) the source clip. Note that this is is not the same as the speed parameter of the Nuke Retime node, which just multiplies the speed value at the current time by the time to obtain the source frame number.
Warp / warp Parametric   Curve that maps input range (after applying speed) to the output range. A low positive slope slows down the input clip, and a negative slope plays it backwards.
Filter / filter Choice Linear
How input images are combined to compute the output image.
None (none): Do not interpolate, ask for images with fractional time to the input effect. Useful if the input effect can interpolate itself.
Nearest (nearest): Pick input image with nearest integer time.
Linear (linear): Blend the two nearest images with linear interpolation.

SlitScan node

pluginIcon

This documentation is for version 1.0 of SlitScan (net.sf.openfx.SlitScan).

Description

Apply per-pixel retiming: the time is computed for each pixel from the retime function, which can be either a horizontal ramp, a vertical ramp, or a retime map.

The default retime function corresponds to a horizontal slit: it is a vertical ramp, which is a linear function of y, which is 0 at the center of the bottom image line, and 1 at the center of the top image line. Optionally, a vertical slit may be used (0 at the center of the leftmost image column, 1 at the center of the rightmost image column), or the optional single-channel “Retime Map” input may also be used.

This plugin requires to render many frames on input, which may require a lot of memory.

Note that the results may be on higher quality if the video is slowed fown (e.g. using slowmoVideo)

The parameters are:

  • retime function (default = horizontal slit)
  • offset for the retime function (default = 0)
  • gain for the retime function (default = -10)
  • absolute, a boolean indicating that the time map gives absolute frames rather than relative frames
  • frame range, only used if the retime function is given by a retime map, because the actual frame range cannot be guessed without inspecting the retime map content (default = -10..0). If “absolute” is checked, this frame range is absolute, else it is relative to the current frame
  • filter to handle time offsets that “fall between” frames. They can be mapped to the nearest frame, or interpolated between the nearest frames (corresponding to a shutter of 1 frame).

Clamp node

pluginIcon

This documentation is for version 2.0 of Clamp (net.sf.openfx.Clamp).

Description

Clamp the values of the selected channels.

A special use case for the Clamp plugin is to generate a binary mask image (i.e. each pixel is either 0 or 1) by thresholding an image. Let us say one wants all input pixels whose value is above or equal to some threshold value to become 1, and all values below this threshold to become 0. Set the “Minimum” value to the threshold, set the “Maximum” to any value strictly below the threshold (e.g. 0 if the threshold is positive), and check “Enable MinClampTo” and “Enable MaxClampTo” while keeping the default values for “MinClampTo” (0.0) and “MaxClampTop” (1.0). The result is a binary mask image. To create a non-binary mask, with softer edges, either blur the output of Clamp, or use the Grade plugin instead, setting the “Black Point” and “White Point” to values close to the threshold, and checking the “Clamp Black” and “Clamp White” options.

ColorLookup node

pluginIcon

This documentation is for version 1.1 of ColorLookup (net.sf.openfx.ColorLookupPlugin).

Description

Apply a parametric lookup curve to each channel separately.

The master curve is combined with the red, green and blue curves, but not with the alpha curve.

Different algorithms are available when applying the master curve, which are selectable using the “Master Curve Mode” parameter.

Computation is faster for values that are within the given range, so it is recommended to set the Range parameter if the input range goes beyond [0,1].

Note that you can easily do color remapping by setting Source and Target colors and clicking “Set RGB” or “Set RGBA” below.

This will add control points on the curve to match the target from the source. You can add as many point as you like.

This is very useful for matching color of one shot to another, or adding custom colors to a black and white ramp.

Master Curve Mode / masterCurveMode Choice Standard
Algorithm that will be used for the master curve. The curve mode will have a strong effect on the appearance of colors, especially if you use a contrast-enhancing curve (S-curve). This can be used for creative effect, but can for some purposes or styles cause undesired color changes depending which mode you choose. Choose a mode that suits your specific taste and needs for the photo at hand. More information can be found at http://rawpedia.rawtherapee.com/Exposure
Standard (standard): The marster curve is applied independently to R, G and B channels. The drawback of this mode is that e.g. considering an S-curve shape to get more contrast, an orange color with a high value of red and green and a low value of blue will tend to shift toward yellow, because the red and green component will be raised, while the blue one will be lowered.
Weighted Standard (weightedstandard): You can use this method to limit the color shift of the standard curve, even if it won’t suppress it entirely.
Film-Like (filmlike): The film-like curve provides a result highly similar to the standard type (that is strong saturation increase with increased contrast), but the RGB-HSV hue is kept constant - that is, there are less color-shift problems. This curve type was designed by Adobe as a part of DNG and is thus the one used by Adobe Camera Raw and Lightroom.
Luminance (luminance): Each component of the pixel is boosted by the same factor so color and saturation is kept stable, that is the result is very true to the original color. However contrast-increasing curves can still lead to a slightly desaturated look. First the relative luminance value of a pixel is obtained, then the curve is applied to that value, the multiplication factor between before and after luminance is calculated, and then this factor is applied to each R, G and B component. The formula used to compute the luminance can be selected using the “luminanceMath” parameter.

Grade node

pluginIcon

This documentation is for version 2.0 of Grade (net.sf.openfx.GradePlugin).

Description

Modify the tonal spread of an image from the white and black points.

This node can also be used to match colors of 2 images: The darkest and lightest points of the target image are converted to black and white using the blackpoint and whitepoint values. These 2 values are then moved to new values using the black(for dark point) and white(for white point). You can also apply multiply/offset/gamma for other color fixing you may need.

Here is the formula used:

A = multiply * (white - black) / (whitepoint - blackpoint)

B = offset + black - A * blackpoint

output = pow(A * input + B, 1 / gamma).

A special use for Grade is to generate a mask image with soft edges by thresholding an input image. Set the “Black Point” and “White Point” to values just below and just above the threshold, and check the “Clamp Black” and “Clamp White” options. If a binary mask containing only 0 and 1 is preferred, the Clamp plugin can be used instead.

HSIToRGB node

This documentation is for version 1.0 of HSIToRGB (net.sf.openfx.HSIToRGB).

Description

Convert from HSI color model (hue, saturation, intensity, as defined by Gonzalez and Woods in 1992) to linear RGB. H is in degrees, S and I are in the same units as RGB. No gamma correction is applied to RGB after conversion.

The HSI colour space (hue, saturation and intensity) attempts to produce a more intuitive representation of colour. The I axis represents the luminance information. The H and S axes are polar coordinates on the plane orthogonal to I. H is the angle, specified such that red is at zero, green at 120 degrees, and blue at 240 degrees. Hue thus represents what humans implicitly understand as colour. S is the magnitude of the colour vector projected in the plane orthogonal to I, and so represents the difference between pastel colours (low saturation) and vibrant colours (high saturation). The main drawback of this colour space is that hue is undefined if saturation is zero, making error propagation in transformations from the RGB colour space more complicated.

It should also be noted that, although the HSI colour space may be more intuitive, is not “perceptual”, in the sense that small displacements of equal size in different parts of the colour space will be perceived by human observers as changes of different magnitude. Attempts have been made to define such colour spaces: CIE-LAB and CIE-LUV are two examples.

OCIOCDLTransform node

pluginIcon

This documentation is for version 1.0 of OCIOCDLTransform (fr.inria.openfx.OCIOCDLTransform).

Description

Use OpenColorIO to apply an ASC Color Decision List (CDL) grade.

The formula applied for each channel is:

out = (in * slope + offset)^power.

The saturation is then applied to all channel using the standard rec709 saturation coefficients:

luma = 0.2126 * inR + 0.7152 * inG + 0.0722 * inB

outR = Clamp( luma + sat * (inR - luma) )

outG = Clamp( luma + sat * (inG - luma) )

outB = Clamp( luma + sat * (inB - luma) ).

The grade can be loaded from an ASC .ccc (Color Correction Collection) or .cc (Color Correction) file.

OCIOFileTransform node

pluginIcon

This documentation is for version 1.0 of OCIOFileTransform (fr.inria.openfx.OCIOFileTransform).

Description

Use OpenColorIO to apply a transform loaded from the given file.

This is usually a 1D or 3D LUT file, but can be other file-based transform, for example an ASC ColorCorrection XML file.

Note that the file’s transform is applied with no special input/output colorspace handling - so if the file expects log-encoded pixels, but you apply the node to a linear image, you will get incorrect results.

Supported formats:

.3dl (flame)

.3dl (lustre)

.ccc (ColorCorrectionCollection)

.cdl (ColorDecisionList)

OCIOLookTransform node

pluginIcon

This documentation is for version 1.0 of OCIOLookTransform (fr.inria.openfx.OCIOLookTransform).

Description

OpenColorIO LookTransform

A ‘look’ is a named color transform, intended to modify the look of an image in a ‘creative’ manner (as opposed to a colorspace definion which tends to be technically/mathematically defined).

Examples of looks may be a neutral grade, to be applied to film scans prior to VFX work, or a per-shot DI grade decided on by the director, to be applied just before the viewing transform.

OCIOLooks must be predefined in the OpenColorIO configuration before usage, and often reference per-shot/sequence LUTs/CCs.

See the ‘Look Combination’ parameter for further syntax details.

See opencolorio.org for look configuration customization examples.

PLogLin node

This documentation is for version 1.0 of PLogLin (net.sf.openfx.PLogLin).

Description

Convert between logarithmic and linear encoding.

This method uses the so-called “Josh Pines log conversion” or “printing density transform” (as described in http://lists.gnu.org/archive/html/openexr-devel/2005-03/msg00006.html), which is based on a single gray point, rather than the white and black points in the Cineon formula (as implemented in the Log2Lin plugin).

Log to Lin conversion: xLin = linRef * pow( 10.0, (xLog * 1023. - logRef)*density/nGamma )

Lin to Log conversion: xLog = (logRef + log10(max( xLin, 1e-10 ) / linRef)*nGamma/density) / 1023.

RGBToHSI node

This documentation is for version 1.0 of RGBToHSI (net.sf.openfx.RGBToHSI).

Description

Convert from linear RGB to HSI color model (hue, saturation, intensity, as defined by Gonzalez and Woods in 1992). H is in degrees, S and I are in the same units as RGB. No gamma correction is applied to RGB before conversion.

The HSI colour space (hue, saturation and intensity) attempts to produce a more intuitive representation of colour. The I axis represents the luminance information. The H and S axes are polar coordinates on the plane orthogonal to I. H is the angle, specified such that red is at zero, green at 120 degrees, and blue at 240 degrees. Hue thus represents what humans implicitly understand as colour. S is the magnitude of the colour vector projected in the plane orthogonal to I, and so represents the difference between pastel colours (low saturation) and vibrant colours (high saturation). The main drawback of this colour space is that hue is undefined if saturation is zero, making error propagation in transformations from the RGB colour space more complicated.

It should also be noted that, although the HSI colour space may be more intuitive, is not “perceptual”, in the sense that small displacements of equal size in different parts of the colour space will be perceived by human observers as changes of different magnitude. Attempts have been made to define such colour spaces: CIE-LAB and CIE-LUV are two examples.

Bloom node

pluginIcon

This documentation is for version 4.0 of Bloom (net.sf.cimg.CImgBloom).

Description

Apply a Bloom filter (Kawase 2004) that sums multiple blur filters of different radii,

resulting in a larger but sharper glare than a simple blur.

It is similar to applying ‘Count’ separate Blur filters to the same input image with sizes ‘Size’, ‘Size’*‘Ratio’, ‘Size’*‘Ratio’^2, etc., and averaging the results.

The blur radii follow a geometric progression (of common ratio 2 in the original implementation, bloomRatio in this implementation), and a total of bloomCount blur kernels are summed up (bloomCount=5 in the original implementation, and the kernels are Gaussian).

The blur filter can be a quasi-Gaussian, a Gaussian, a box, a triangle or a quadratic filter.

Ref.: Masaki Kawase, “Practical Implementation of High Dynamic Range Rendering”, GDC 2004.

Uses the ‘vanvliet’ and ‘deriche’ functions from the CImg library.

Mask   Yes
Controls
Parameter / script name Type Default Function
Size / size Double x: 0 y: 0 Size (diameter) of the filter kernel, in pixel units (>=0). The standard deviation of the corresponding Gaussian is size/2.4. No filter is applied if size < 1.2.
Uniform / uniform Boolean Off Apply the same amount of blur on X and Y.
Ratio / bloomRatio Double 2 Ratio between successive kernel sizes of the bloom filter. A ratio of 1 gives no Bloom effect, just the original blur. A higher ratio gives a blur kernel with a heavier tail. The original implementation uses a value of 2.
Count / bloomCount Integer 5 Number of blur kernels of the bloom filter. The original implementation uses a value of 5. Higher values give a wider of heavier tail (the size of the largest blur kernel is 2**bloomCount * size). A count of 1 is just the original blur.
Border Conditions / boundary Choice Nearest
Specifies how pixel values are computed out of the image domain. This mostly affects values at the boundary of the image. If the image represents intensities, Nearest (Neumann) conditions should be used. If the image represents gradients or derivatives, Black (Dirichlet) boundary conditions should be used.
Black (black): Dirichlet boundary condition: pixel values out of the image domain are zero.
Nearest (nearest): Neumann boundary condition: pixel values out of the image domain are those of the closest pixel location in the image domain.
Filter / filter Choice Quasi-Gaussian
Bluring filter. The quasi-Gaussian filter should be appropriate in most cases. The Gaussian filter is more isotropic (its impulse response has rotational symmetry), but slower.
Quasi-Gaussian (quasigaussian): Quasi-Gaussian filter (0-order recursive Deriche filter, faster) - IIR (infinite support / impulsional response).
Gaussian (gaussian): Gaussian filter (Van Vliet recursive Gaussian filter, more isotropic, slower) - IIR (infinite support / impulsional response).
Box (box): Box filter - FIR (finite support / impulsional response).
Triangle (triangle): Triangle/tent filter - FIR (finite support / impulsional response).
Quadratic (quadratic): Quadratic filter - FIR (finite support / impulsional response).
Expand RoD / expandRoD Boolean Off Expand the source region of definition by 1.5*size (3.6*sigma).
Crop To Format / cropToFormat Boolean On If the source is inside the format and the effect extends it outside of the format, crop it to avoid unnecessary calculations. To avoid unwanted crops, only the borders that were inside of the format in the source clip will be cropped.
Alpha Threshold / alphaThreshold Double 0 If this value is non-zero, any alpha value below this is set to zero. This is only useful for IIR filters (Gaussian and Quasi-Gaussian), which may produce alpha values very close to zero due to arithmetic precision. Remind that, in theory, a black image with a single white pixel should produce non-zero values everywhere, but a few VFX tricks rely on the fact that alpha should be zero far from the alpha edges (e.g. the premult-blur-unpremult trick to fill holes)). A threshold value of 0.003 is reasonable, and values between 0.001 and 0.01 are usually enough to remove these artifacts.
(Un)premult / premult Boolean Off Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
Invert Mask / maskInvert Boolean Off When checked, the effect is fully applied where the mask is 0.
Mix / mix Double 1 Mix factor between the original and the transformed image.

Blur node

pluginIcon

This documentation is for version 4.0 of Blur (net.sf.cimg.CImgBlur).

Description

Blur input stream or compute derivatives.

The blur filter can be a quasi-Gaussian, a Gaussian, a box, a triangle or a quadratic filter.

Note that the Gaussian filter [1] is implemented as an IIR (infinite impulse response) filter [2][3], whereas most compositing software implement the Gaussian as a FIR (finite impulse response) filter by cropping the Gaussian impulse response. Consequently, when blurring a white dot on black background, it produces very small values very far away from the dot. The quasi-Gaussian filter is also IIR.

A very common process in compositing to expand colors on the edge of a matte is to use the premult-blur-unpremult combination [4][5]. The very small values produced by the IIR Gaussian filter produce undesirable artifacts after unpremult. For this process, the FIR quadratic filter (or the faster triangle or box filters) should be preferred over the IIR Gaussian filter.

DenoiseSharpen node

This documentation is for version 1.0 of DenoiseSharpen (net.sf.openfx.DenoiseSharpen).

Description

Denoise and/or sharpen images using wavelet-based algorithms.

Description

This plugin allows the separate denoising of image channels in multiple color spaces using wavelets, using the BayesShrink algorithm, and can also sharpen the image details.

Noise levels for each channel may be either set manually, or analyzed from the image data in each wavelet subband using the MAD (median absolute deviation) estimator. Noise analysis is based on the assumption that the noise is Gaussian and additive (it is not intensity-dependent). If there is speckle or salt-and-pepper noise in the images, the Median or SmoothPatchBased filters may be more appropriate. The color model specifies the channels and the transforms used. Noise levels have to be re-adjusted or re-analyzed when changing the color model.

Basic Usage

The input image should be in linear RGB.

For most footage, the effect works best by keeping the default Y’CbCr color model. The color models are made to work with Rec.709 data, but DenoiseSharpen will still work if the input is in another colorspace, as long as the input is linear RGB:

  • The Y’CbCr color model uses the Rec.709 opto-electronic transfer function to convert from RGB to R’G’B’ and the the Rec.709 primaries to convert from R’G’B’ to Y’CbCr.
  • The L * a * b color model uses the Rec.709 RGB primaries to convert from RGB to L * a * b.
  • The R’G’B’ color model uses the Rec.709 opto-electronic transfer function to convert from RGB to R’G’B’.
  • The RGB color model (linear) makes no assumption about the RGB color space, and works directly on the RGB components, assuming additive noise. This is the only option if the noisy source contains negative values. If, say, the noise is known to be multiplicative, one can convert the images to Log before denoising, use this option, and convert back to linear after denoising.
  • The Alpha channel, if processed, is always considered to be linear.

The simplest way to use this plugin is to leave the noise analysis area to the whole image, and click “Analyze Noise Levels”. Once the analysis is done, “Lock Noise Analysis” is checked in order to avoid modifying the essential parameters by mistake.

If the image has many textured areas, it may be preferable to select an analysis area with flat colors, free from any details, shadows or highlights, to avoid considering texture as noise. The AnalysisMask input can be used to mask the analysis, if the rectangular area is not appropriate. Any non-zero pixels in the mask are taken into account. A good option for the AnalysisMask would be to take the inverse of the output of an edge detector and clamp it correctly so that all pixels near the edges have a value of zero..

If the sequence to be denoised does not have enough flat areas, you can also connect a reference footage with the same kind of noise to the AnalysisSource input: that source will be used for the analysis only. If no source with flat areas is available, and noise analysis can only be performed on areas which also contain details, it is often preferable to disable very low, low, and sometimes medium frequencies in the “Frequency Tuning” parameters group, or at least to lower their gain, since they may be misestimated by the noise analysis process. If the noise is IID (independent and identically distributed), such as digital sensor noise, only “Denoise High Frequencies” should be checked. If the noise has some grain (i.e. it commes from lossy compression of noisy images by a camera, or it is scanned film), then you may want to enable medium frequencies as well. If low and very low frequencies are enabled, but the analysis area is not a flat zone, the signal itself (i.e. the noise-free image) could be considered as noise, and the result may exhibit low contrast and blur.

To check what details have been kept after denoising, you can raise the Sharpen Amount to something like 10, and then adjust the Noise Level Gain to get the desired denoising amount, until no noise is left and only image details remain in the sharpened image. You can then reset the Sharpen Amount to zero, unless you actually want to enhance the contrast of your denoised footage.

You can also check what was actually removed from the original image by selecting the “Noise” Output mode (instead of “Result”). If too many image details are visible in the noise, noise parameters may need to be tuned.

This plugin was compiled with OpenMP support.

Controls
Parameter / script name Type Default Function
Output / outputMode Choice Result
Select which image is output when analysis is locked. When analysis is not locked, the effect does nothing (the output is the source image).
Result (result): The result of denoising and sharpening the Source image.
Noise (noise): An image containing what would be added to the image to denoise it. If ‘Denoise Amount’ is zero, this image should be black. Only noise should be visible in this image. If you can see a lot of picture detail in the noise output, it means the current settings are denoising too hard and remove too much of the image, which leads to a smoothed result. Try to lower the noise levels or the noise level gain.
Sharpen (sharpen): An image containing what would be added to the image to sharpen it. If ‘Sharpen Amount’ is zero, this image should be black. Only image details should be visible in this image. If you can see a lot of noise in the sharpen output, it means the current settings are denoising not enough, which leads to a noisy result. Try to raise the noise levels or the noise level gain.
Color Model / colorModel Choice Y’CbCr(A)
The colorspace where denoising is performed. These colorspaces assume that input and output use the Rec.709/sRGB chromaticities and the D65 illuminant, but should tolerate other input colorspaces (the output colorspace will always be the same as the input colorspace). Noise levels are reset when the color model is changed.
Y’CbCr(A) (ycbcr): The YCbCr color model has one luminance channel (Y) which contains most of the detail information of an image (such as brightness and contrast) and two chroma channels (Cb = blueness, Cr = reddness) that hold the color information. Note that this choice drastically affects the result. Uses the Rec.709 opto-electronic transfer function to convert from RGB to R’G’B’ and the the Rec.709 primaries to convert from R’G’B’ to Y’CbCr.
CIE L*a*b(A) (cielab): CIE L*a*b* is a color model in which chrominance is separated from lightness and color distances are perceptually uniform. Note that this choice drastically affects the result. Uses the Rec.709 primaries to convert from RGB to L*a*b.
R’G’B’(A) (gammargb): The R’G’B’ color model (gamma-corrected RGB) separates an image into channels of red, green, and blue. Note that this choice drastically affects the result. Uses the Rec.709 opto-electronic transfer function to convert from RGB to R’G’B’.
RGB(A) (linearrgb): The Linear RGB color model processes the raw linear components. Usually a bad choice, except when denoising non-color data (e.g. depth or motion vectors). No assumption is made about the RGB color space.
Lock Analysis and Apply / analysisLock Boolean Off Lock all noise analysis parameters and apply denoising. When the analysis is not locked, the source image is output.
Bottom Left / bottomLeft Double x: 0.1 y: 0.1 Coordinates of the bottom left corner of the analysis rectangle. This rectangle is intersected with the AnalysisMask input, if connected.
Size / size Double w: 0.8 h: 0.8 Width and height of the analysis rectangle. This rectangle is intersected with the AnalysisMask input, if connected.
B3 Spline Interpolation / useB3Spline Boolean On For wavelet decomposition, use a 5x5 filter based on B3 spline interpolation rather than a 3x3 Lagrange linear filter. Noise levels are reset when this setting is changed. The influence of this parameter is minimal, and it should not be changed.
Analysis Frame / analysisFrame Integer -1 The frame number where the noise levels were analyzed.
Analyze Noise Levels / analyzeNoiseLevels Button   Computes the noise levels from the current frame and current color model. To use the same settings for the whole sequence, analyze a frame that is representative of the sequence. If a mask is set, it is used to compute the noise levels from areas where the mask is non-zero. If there are keyframes on the noise level parameters, this sets a keyframe at the current frame. The noise levels can then be fine-tuned.

Noise Level Gain / noiseLevelGain Double 1 Global gain to apply to the noise level thresholds. 0 means no denoising, 1 means use the estimated thresholds multiplied by the per-frequency gain and the channel gain. The default value (1.0) is rather conservative (it does not destroy any kind of signal). Values around 1.1 or 1.2 usually give more pleasing results.
Denoise Amount / denoiseAmount Double 1 The amount of denoising to apply. 0 means no denoising (which may be useful to sharpen without denoising), between 0 and 1 does a soft thresholding of below the thresholds, thus keeping some noise, and 1 applies the threshold strictly and removes everything below the thresholds. This should be used only if you want to keep some noise, for example for noise matching. This value is multiplied by the per-channel amount se in the ‘Channel Tuning’ group. Remember that the thresholds are multiplied by the per-frequency gain, the channel gain, and the Noise Level Gain first.

Low Gain / gainFreqLow Double 1 Gain to apply to the low frequency noise level thresholds. 0 means no denoising, 1 means use the estimated thresholds multiplied by the channel Gain and the Noise Level Gain.
Denoise Very Low Frequencies / enableFreqVeryLow Boolean On Check to enable the very low frequency noise level thresholds. Can be disabled in most cases. Must be disabled if the analysis area contains texture, or if the noise is known to be IID (independent and identically distributed), for example if this is only sensor noise and lossless compression is used, and not grain or compression noise.
Very Low Gain / gainFreqVeryLow Double 1 Gain to apply to the very low frequency noise level thresholds. 0 means no denoising, 1 means use the estimated thresholds multiplied by the channel Gain and the global Noise Level Gain.
Adaptive Radius / adaptiveRadius Integer 4 Radius of the window where the signal level is analyzed at each scale. If zero, the signal level is computed from the whole image, which may excessively blur the edges if the image has many flat color areas. A reasonable value should to be in the range 2-4.
Y Gain / ylrGain Double 1 Gain to apply to the thresholds for this channel. 0 means no denoising, 1 means use the estimated thresholds multiplied by the per-frequency gain and the global Noise Level Gain.
Y Amount / ylrAmount Double 1 The amount of denoising to apply to the specified channel. 0 means no denoising, between 0 and 1 does a soft thresholding of below the thresholds, thus keeping some noise, and 1 applies the threshold strictly and removes everything below the thresholds. This should be used only if you want to keep some noise, for example for noise matching. This value is multiplied by the global Denoise Amount. Remember that the thresholds are multiplied by the per-frequency gain, the channel gain, and the Noise Level Gain first.
Cb Gain / cbagGain Double 1 Gain to apply to the thresholds for this channel. 0 means no denoising, 1 means use the estimated thresholds multiplied by the per-frequency gain and the global Noise Level Gain.
Cb Amount / cbagAmount Double 1 The amount of denoising to apply to the specified channel. 0 means no denoising, between 0 and 1 does a soft thresholding of below the thresholds, thus keeping some noise, and 1 applies the threshold strictly and removes everything below the thresholds. This should be used only if you want to keep some noise, for example for noise matching. This value is multiplied by the global Denoise Amount. Remember that the thresholds are multiplied by the per-frequency gain, the channel gain, and the Noise Level Gain first.
Cr Gain / crbbGain Double 1 Gain to apply to the thresholds for this channel. 0 means no denoising, 1 means use the estimated thresholds multiplied by the per-frequency gain and the global Noise Level Gain.
Cr Amount / crbbAmount Double 1 The amount of denoising to apply to the specified channel. 0 means no denoising, between 0 and 1 does a soft thresholding of below the thresholds, thus keeping some noise, and 1 applies the threshold strictly and removes everything below the thresholds. This should be used only if you want to keep some noise, for example for noise matching. This value is multiplied by the global Denoise Amount. Remember that the thresholds are multiplied by the per-frequency gain, the channel gain, and the Noise Level Gain first.
Alpha Gain / alphaGain Double 1 Gain to apply to the thresholds for this channel. 0 means no denoising, 1 means use the estimated thresholds multiplied by the per-frequency gain and the global Noise Level Gain.
Alpha Amount / alphaAmount Double 1 The amount of denoising to apply to the specified channel. 0 means no denoising, between 0 and 1 does a soft thresholding of below the thresholds, thus keeping some noise, and 1 applies the threshold strictly and removes everything below the thresholds. This should be used only if you want to keep some noise, for example for noise matching. This value is multiplied by the global Denoise Amount. Remember that the thresholds are multiplied by the per-frequency gain, the channel gain, and the Noise Level Gain first.
Sharpen Amount / sharpenAmount Double 0 Adjusts the amount of sharpening applied. Be careful that only components that are above the noise levels are enhanced, so the noise level gain parameters are very important for proper sharpening. For example, if ‘Noise Level Gain’ is set to zero (0), then noise is sharpened as well as signal. If the ‘Noise Level Gain’ is set to one (1), only signal is sharpened. In order to sharpen without denoising, set the ‘Denoise Amount’ parameter to zero (0).
Sharpen Size / sharpenSize Double 10 Adjusts the size of the sharpening. For very unsharp images it is recommended to use higher values. Default is 10.
Sharpen Y Only / sharpenLuminance Boolean On Sharpens luminance only (if colormodel is R’G’B’, sharpen only RGB). This avoids color artifacts to appear. Colour sharpness in natural images is not critical for the human eye.
(Un)premult / premult Boolean Off Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
Invert Mask / maskInvert Boolean Off When checked, the effect is fully applied where the mask is 0.
Mix / mix Double 1 Mix factor between the original and the transformed image.

EdgeDetect node

pluginIcon

This documentation is for version 4.0 of EdgeDetect (eu.cimg.EdgeDetect).

Description

Perform edge detection by computing the image gradient magnitude. Optionally, edge detection can be preceded by blurring, and followed by erosion and thresholding. In most cases, EdgeDetect is followed a Grade node to extract the proper edges and generate a mask from these.

For color or multi-channel images, several edge detection algorithms are proposed to combine the gradients computed in each channel:

  • Separate: the gradient magnitude is computed in each channel separately, and the output is a color edge image.
  • RMS: the RMS of per-channel gradients magnitudes is computed.
  • Max: the maximum per-channel gradient magnitude is computed.
  • Tensor: the tensor gradient norm [1].

EdgeExtend node

pluginIcon

This documentation is for version 4.0 of EdgeExtend (eu.cimg.EdgeExtend).

Description

Fill a matte (i.e. a non-opaque color image with an alpha channel) by extending the edges of the matte. This effect does nothing an an opaque image.

If the input matte comes from a keyer, the alpha channel of the matte should be first eroded by a small amount to remove pixels containing mixed foreground/background colors. If not, these mixed colors may be extended instead of the pure foreground colors.

The filling process works by iteratively blurring the image, and merging the non-blurred image over the image to get to the next iteration. There are exactly ‘Slices’ such operations. The blur size at each iteration is linearly increasing.

‘Size’ is thus the total size of the edge extension, and ‘Slices’ is an indicator of the precision: the more slices there are, the sharper is the final image near the original edges.

Optionally, the image can be multiplied by the alpha channel on input (premultiplied), and divided by the alpha channel on output (unpremultiplied), so that if RGB contain an image and Alpha contains a mask, the output is an image where the RGB is smeared from the non-zero areas of the mask to the zero areas of the same mask.

The ‘Size’ parameter gives the size of the largest blur kernel, ‘Count’ gives the number of blur kernels, and ‘Ratio’ gives the ratio between consecutive blur kernel sizes. The size of the smallest blur kernel is thus ‘Size’/‘Ratio’^(‘Count’-1)

To get the classical single unpremult-blur-premult, use ‘Count’=1 and set the size to the size of the blur kernel. However, near the mask borders, a frontier can be seen between the non-blurred area (this inside of the mask) and the blurred area. Using more blur sizes will give a much smoother transition.

The idea for the builtup blurs to expand RGB comes from the EdgeExtend effect for Nuke by Frank Rueter (except the blurs were merged from the smallest to the largest, and here it is done the other way round), with suggestions by Lucas Pfaff.

ErodeBlur node

This documentation is for version 4.0 of ErodeBlur (eu.cimg.ErodeBlur).

Description

Performs an operation that looks like an erosion or a dilation by smoothing the image and then remapping the values of the result.

The image is first smoothed by a triangle filter of width 2*abs(size).

Now suppose the image is a 0-1 step edge (I=0 for x less than 0, I=1 for x greater than 0). The intensities are linearly remapped so that the value at x=size-0.5 is mapped to 0 and the value at x=size+0.5 is mapped to 1.

This process usually works well for mask images (i.e. images which are either 0 or 1), but may give strange results on images with real intensities, where another Erode filter has to be used.

ErodeSmooth node

pluginIcon

This documentation is for version 2.0 of ErodeSmooth (net.sf.cimg.CImgErodeSmooth).

Description

Erode or dilate input stream using a normalized power-weighted filter.

This gives a smoother result than the Erode or Dilate node.

See “Robust local max-min filters by normalized power-weighted filtering” by L.J. van Vliet, http://dx.doi.org/10.1109/ICPR.2004.1334273

Uses the ‘vanvliet’ and ‘deriche’ functions from the CImg library.

Parameter / script name Type Default Function
Range / range Double min: 0 max: 1 Expected range for input values.
Size / size Double x: 0 y: 0 Size (diameter) of the filter kernel, in pixel units (>=0). The standard deviation of the corresponding Gaussian is size/2.4. No filter is applied if size < 1.2. Negative values correspond to dilation, positive values to erosion. Both values should have the same sign.
Uniform / uniform Boolean Off Apply the same amount of blur on X and Y.
Exponent / exponent Integer 5 Exponent of the normalized power-weighted filter. Lower values give a smoother result. Default is 5.
Border Conditions / boundary Choice Nearest
Specifies how pixel values are computed out of the image domain. This mostly affects values at the boundary of the image. If the image represents intensities, Nearest (Neumann) conditions should be used. If the image represents gradients or derivatives, Black (Dirichlet) boundary conditions should be used.
Black (black): Dirichlet boundary condition: pixel values out of the image domain are zero.
Nearest (nearest): Neumann boundary condition: pixel values out of the image domain are those of the closest pixel location in the image domain.
Filter / filter Choice Quadratic
Bluring filter. The quasi-Gaussian filter should be appropriate in most cases. The Gaussian filter is more isotropic (its impulse response has rotational symmetry), but slower.
Quasi-Gaussian (quasigaussian): Quasi-Gaussian filter (0-order recursive Deriche filter, faster).
Gaussian (gaussian): Gaussian filter (Van Vliet recursive Gaussian filter, more isotropic, slower).
Box (box): Box filter - FIR (finite support / impulsional response).
Triangle (triangle): Triangle/tent filter - FIR (finite support / impulsional response).
Quadratic (quadratic): Quadratic filter - FIR (finite support / impulsional response).

GMICExpr node

pluginIcon

This documentation is for version 2.1 of GMICExpr (net.sf.cimg.CImgExpression).

Description

Quickly generate or process image from mathematical formula evaluated for each pixel. Full documentation for G’MIC/CImg expressions is reproduced below and available online from the G’MIC help. The only additions of this plugin are the predefined variables T (current time) and K (render scale).

Uses the ‘fill’ function from the CImg library. CImg is a free, open-source library distributed under the CeCILL-C (close to the GNU LGPL) or CeCILL (compatible with the GNU GPL) licenses. It can be used in commercial applications (see http://cimg.eu).

Sample expressions
  • j(sin(y/100/K+T/10)*20*K,sin(x/100/K+T/10)*20*K)’ distorts the image with time-varying waves.
  • 0.5*(j(1)-j(-1))’ estimates the X-derivative of an image with a classical finite difference scheme.
  • if(x%10==0,1,i)’ draws blank vertical lines on every 10th column of an image.
  • sqrt(zr=-1.2+2.4*x/w;zi=-1.2+2.4*y/h;for(i=0,zr*zr+zi*zi<=4&&i<256,t=zr*zr-zi*zi+0.4;zi=2*zr*zi+0.2;zr=t; i=i+1))/255’ draws the Mandelbrot fractal (give it a 1024x1024 image as input).
Expression language
  • The expression is evaluated for each pixel of the selected images.
  • The mathematical parser understands the following set of functions, operators and variables:
    • Usual operators: || (logical or), && (logical and), | (bitwise or), & (bitwise and), !=, ==, <=, >=, <, >, << (left bitwise shift), >> (right bitwise shift), -, +, *, /, % (modulo), ^ (power), ! (logical not), ~ (bitwise not), ++, --, +=, -=, *=, /=, %=, &=, |=, ^=, >>=, <<= (in-place operators).
    • Usual math functions: abs(), acos(), arg(), argkth(), argmax(), argmin(), asin(), atan(), atan2(), avg(), bool(), cbrt(), ceil(), cos(), cosh(), cut(), exp(), fact(), fibo(), floor(), gauss(), int(), isval(), isnan(), isinf(), isint(), isbool(), isfile(), isdir(), isin(), kth(), log(), log2(), log10(), max(), mean(), med(),min(),narg(),prod(),rol()(left bit rotation),ror()(right bit rotation),round(),sign(),sin(),sinc(),sinh(),sqrt(),std(),srand(_seed),sum(),tan(),tanh(),variance(),xor().   * 'atan2(y,x)' is the version of 'atan()' with two arguments __'y'__ and __'x'__ (as in C/C\+\+).   * 'permut(k,n,with_order)' computes the number of permutations of __k__ objects from a set of __n__ objects.   * 'gauss(x,_sigma)' returns __'exp(-x\^2/(2\*s\^2))/sqrt(2\*pi\*sigma\^2)'__.   * 'cut(value,min,max)' returns value if it is in range __\[min,max\]__, or __min__ or __max__ otherwise.   * 'narg(a_1,…,a_N)' returns the number of specified arguments (here, __N__).   * 'arg(i,a_1,..,a_N)' returns the __ith__ argument __a_i__.   * 'isval()', 'isnan()', 'isinf()', 'isint()', 'isbool()' test the type of the given number or expression, and return __0 (false)__ or __1 (true)__.   * 'isfile()' (resp. 'isdir()') returns __0 (false)__ or __1 (true)__ whether its argument is a path to an existing file (resp. to a directory) or not.   * 'isin(v,a_1,…,a_n)' returns __0 (false)__ or __1 (true)__ whether the first value __'v'__ appears in the set of other values 'a_i'.   * 'argmin()', 'argmax()', 'kth()', 'max()', 'mean()', 'med()', 'min()', 'std()', 'sum()' and 'variance()' can be called with an arbitrary number of scalar/vector arguments.   * 'round(value,rounding_value,direction)`’ returns a rounded value. ‘direction’ can be { -1=to-lowest | 0=to-nearest | 1=to-highest }.
    • Variable names below are pre-defined. They can be overridden.
      • l’: length of the associated list of images.
      • w’: width of the associated image, if any (0 otherwise).
      • h’: height of the associated image, if any (0 otherwise).
      • d’: depth of the associated image, if any (0 otherwise).
      • s’: spectrum of the associated image, if any (0 otherwise).
      • r’: shared state of the associated image, if any (0 otherwise).
      • wh’: shortcut for width x height.
      • whd’: shortcut for width x height x depth.
      • whds’: shortcut for width x height x depth x spectrum (i.e. number of image values).
      • im’,‘iM’,‘ia’,‘iv’,‘is’,‘ip’,‘ic’: Respectively the minimum, maximum, average, variance, sum, product and median value of the associated image, if any (0 otherwise).
      • xm’,‘ym’,‘zm’,‘cm’: The pixel coordinates of the minimum value in the associated image, if any (0 otherwise).
      • xM’,‘yM’,‘zM’,‘cM’: The pixel coordinates of the maximum value in the associated image, if any (0 otherwise).
      • All these variables are considered as constant values by the math parser (for optimization purposes) which is indeed the case most of the time. Anyway, this might not be the case, if function ‘resize(#ind,..)’ is used in the math expression. If so, it is safer to invoke functions ‘l()’, ‘w(_#ind)’, ‘h(_#ind)’, … ‘s(_#ind)’ and ‘ic(_#ind)’ instead of the corresponding named variables.
      • i’: current processed pixel value (i.e. value located at (x,y,z,c)) in the associated image, if any (0 otherwise).
      • iN’: Nth channel value of current processed pixel (i.e. value located at (x,y,z,N)) in the associated image, if any (0 otherwise). ‘N’ must be an integer in range [0,9].
      • R’,‘G’,‘B’ and ‘A’ are equivalent to ‘i0’, ‘i1’, ‘i2’ and ‘i3’ respectively.
      • I’: current vector-valued processed pixel in the associated image, if any (0 otherwise). The number of vector components is equal to the number of image channels (e.g. I = [ R,G,B ] for a RGB image).
      • You may add ‘#ind’ to any of the variable name above to retrieve the information for any numbered image [ind] of the list (when this makes sense). For instance ‘ia#0’ denotes the average value of the first image of the list).
      • x’: current processed column of the associated image, if any (0 otherwise).
      • y’: current processed row of the associated image, if any (0 otherwise).
      • z’: current processed slice of the associated image, if any (0 otherwise).
      • c’: current processed channel of the associated image, if any (0 otherwise).
      • t’: thread id when an expression is evaluated with multiple threads (0 means ‘master thread’).
      • T’: current time [OpenFX-only].
      • K’: render scale (1 means full scale, 0.5 means half scale) [OpenFX-only].
      • e’: value of e, i.e. 2.71828…
      • pi’: value of pi, i.e. 3.1415926…
      • u’: a random value between [0,1], following a uniform distribution.
      • g’: a random value, following a gaussian distribution of variance 1 (roughly in [-6,6]).
      • interpolation’: value of the default interpolation mode used when reading pixel values with the pixel access operators (i.e. when the interpolation argument is not explicitly specified, see below for more details on pixel access operators). Its initial default value is 0.
      • boundary’: value of the default boundary conditions used when reading pixel values with the pixel access operators (i.e. when the boundary condition argument is not explicitly specified, see below for more details on pixel access operators). Its initial default value is 0.
    • Vector calculus: Most operators are also able to work with vector-valued elements.
      • [ a0,a1,...,aN ]’ defines a (N+1)-dimensional vector with scalar coefficients ak.
      • vectorN(a0,a1,,...,)’ does the same, with the ak being repeated periodically if only a few are specified.
      • In both previous expressions, the ak can be vectors themselves, to be concatenated into a single vector.
      • The scalar element ak of a vector X is retrieved by ‘X[k]’.
      • The sub-vector [ X[p]…X[p+q-1] ] (of size q) of a vector X is retrieved by ‘X[p,q]’.
      • Equality/inequality comparisons between two vectors is done with operators ‘==’ and ‘!=’.
      • Some vector-specific functions can be used on vector values: ‘cross(X,Y)’ (cross product), ‘dot(X,Y)’ (dot product), ‘size(X)’ (vector dimension), ‘sort(X,_is_increasing,_chunk_size)’ (sorting values), ‘reverse(A)’ (reverse order of components), ‘shift(A,_length,_boundary_conditions)’ and ‘same(A,B,_nb_vals,_is_case_sensitive)’ (vector equality test).
      • Function ‘normP(u1,...,un)’ computes the LP-norm of the specified vector (P being an unsigned integer constant or ’inf’). If P is omitted, the L2 norm is used.
      • Function ‘resize(A,size,_interpolation,_boundary_conditions)’ returns a resized version of a vector ‘A’ with specified interpolation mode. ‘interpolation’ can be { -1=none (memory content) | 0=none | 1=nearest | 2=average | 3=linear | 4=grid | 5=bicubic | 6=lanczos }, and ‘boundary_conditions’ can be { 0=dirichlet | 1=neumann | 2=periodic | 3=mirror }.
      • Function ‘find(A,B,_is_forward,_starting_indice)’ returns the index where sub-vector B appears in vector A, (or -1 if B is not found in A). Argument A can be also replaced by an image indice #ind.
      • A 2-dimensional vector may be seen as a complex number and used in those particular functions/operators: ‘**’ (complex multiplication), ‘//’ (complex division), ‘^^’ (complex exponentiation), ‘**=’ (complex self-multiplication), ‘//=’ (complex self-division), ‘^^=’ (complex self-exponentiation), ‘cabs()’ (complex modulus), ‘carg()’ (complex argument), ‘cconj()’ (complex conjugate), ‘cexp()’ (complex exponential) and ‘clog()’ (complex logarithm).
      • A MN-dimensional vector may be seen as a M x N matrix and used in those particular functions/operators: ‘*’ (matrix-vector multiplication), ‘det(A)’ (determinant), ‘diag(V)’ (diagonal matrix from a vector), ‘eig(A)’ (eigenvalues/eigenvectors), ‘eye(n)’ (n x n identity matrix), ‘inv(A)’ (matrix inverse), ‘mul(A,B,_nb_colsB)’ (matrix-matrix multiplication), ‘pseudoinv(A,_nb_colsA)’, ‘rot(u,v,w,angle)’ (3d rotation matrix), ‘rot(angle)’ (2d rotation matrix), ‘solve(A,B,_nb_colsB)’ (least-square solver of linear system A.X = B), ‘svd(A,_nb_colsA)’ (singular value decomposition), ‘trace(A)’ (matrix trace) and ‘transp(A,nb_colsA)’ (matrix transpose). Argument ‘nb_colsB’ may be omitted if it is equal to 1.
      • Specifying a vector-valued math expression as an argument of a command that operates on image values (e.g. ‘fill’) modifies the whole spectrum range of the processed image(s), for each spatial coordinates (x,y,z). The command does not loop over the C-axis in this case.
    • String manipulation: Character strings are defined and managed as vectors objects. Dedicated functions and initializers to manage strings are
      • [ 'string' ] and 'string' define a vector whose values are the ascii codes of the specified character string (e.g. 'foo' is equal to [ 102,111,111 ]).
      • _'character' returns the (scalar) ascii code of the specified character (e.g. _'A' is equal to 65).
      • A special case happens for empty strings: Values of both expressions [ '' ] and '' are 0.
      • Functions ‘lowercase()’ and ‘uppercase()’ return string with all string characters lowercased or uppercased.
      • Function ‘stov(str,_starting_indice,_is_strict)’ parses specified string ‘str’ and returns the value contained in it.
      • Function ‘vtos(expr,_nb_digits,_siz)’ returns a vector of size ‘siz’ which contains the ascii representation of values described by expression ‘expr’. ‘nb_digits’ can be { -1=auto-reduced | 0=all | >0=max number of digits }.
      • Function ‘echo(str1,str2,...,strN)’ prints the concatenation of given string arguments on the console.
      • Function ‘cats(str1,str2,...,strN,siz)’ returns the concatenation of given string arguments as a new vector of size ‘siz’.
    • Special operators can be used:
      • ;’: expression separator. The returned value is always the last encountered expression. For instance expression ‘1;2;pi’ is evaluated as ‘pi’.
      • =’: variable assignment. Variables in mathematical parser can only refer to numerical values (vectors or scalars). Variable names are case-sensitive. Use this operator in conjunction with ‘;’ to define more complex evaluable expressions, such as ‘t=cos(x);3*t^2+2*t+1’. These variables remain local to the mathematical parser and cannot be accessed outside the evaluated expression.
      • Variables defined in math parser may have a constant property, by specifying keyword const before the variable name (e.g. const foo = pi/4;). The value set to such a variable must be indeed a constant scalar. Constant variables allows certain types of optimizations in the math JIT compiler.
    • The following specific functions are also defined:
      • u(max)’ or ‘u(min,max)’: return a random value between [0,max] or [min,max], following a uniform distribution.
      • i(_a,_b,_c,_d,_interpolation_type,_boundary_conditions)’: return the value of the pixel located at position (a,b,c,d) in the associated image, if any (0 otherwise). ‘interpolation_type’ can be { 0=nearest neighbor | other=linear }. ‘boundary_conditions’ can be { 0=dirichlet | 1=neumann | 2=periodic | 3=mirror }. Omitted coordinates are replaced by their default values which are respectively x, y, z, c, interpolation and boundary. For instance command ‘fill 0.5*(i(x+1)-i(x-1))’ will estimate the X-derivative of an image with a classical finite difference scheme.
      • j(_dx,_dy,_dz,_dc,_interpolation_type,_boundary_conditions)’ does the same for the pixel located at position (x+dx,y+dy,z+dz,c+dc) (pixel access relative to the current coordinates).
      • i[offset,_boundary_conditions]’ returns the value of the pixel located at specified ‘offset’ in the associated image buffer (or 0 if offset is out-of-bounds).
      • j[offset,_boundary_conditions]’ does the same for an offset relative to the current pixel coordinates (x,y,z,c).
      • i(#ind,_x,_y,_z,_c,_interpolation,_boundary_conditions)’, ‘j(#ind,_dx,_dy,_dz,_dc,_interpolation,_boundary_conditions)’, ‘i[#ind,offset,_boundary_conditions]’ and ‘i[offset,_boundary_conditions]’ are similar expressions used to access pixel values for any numbered image [ind] of the list.
      • I/J[offset,_boundary_conditions]’ and ‘I/J(#ind,_x,_y,_z,_interpolation,_boundary_conditions)’ do the same as ‘i/j[offset,_boundary_conditions]’ and ‘i/j(#ind,_x,_y,_z,_c,_interpolation,_boundary_conditions)’ but return a vector instead of a scalar (e.g. a vector [ R,G,B ] for a pixel at (a,b,c) in a color image).
      • sort(#ind,_is_increasing,_axis)’ sorts the values in the specified image [ind].
      • crop(_#ind,_x,_y,_z,_c,_dx,_dy,_dz,_dc,_boundary_conditions)’ returns a vector whose values come from the cropped region of image [ind] (or from default image selected if ‘ind’ is not specified). Cropped region starts from point (x,y,z,c) and has a size of dx x dy x dz x dc. Arguments for coordinates and sizes can be omitted if they are not ambiguous (e.g. ‘crop(#ind,x,y,dx,dy)’ is a valid invocation of this function).
      • draw(_#ind,S,x,y,z,c,dx,_dy,_dz,_dc,_opacity,_M,_max_M)’ draws a sprite S in image [ind] (or in default image selected if ‘ind’ is not specified) at coordinates (x,y,z,c). The size of the sprite dx x dy x dz x dc must be specified. You can also specify a corresponding opacity mask M if its size matches S.
      • resize(#ind,w,_h,_d,_s,_interp,_boundary_conditions,cx,_cy,_cz,_cc)’ resizes an image of the associated list with specified dimension and interpolation method. When using this, function, you should consider retrieving the (non-constant) image dimensions using the dynamic functions ‘w(_#ind)’, ‘h(_#ind)’, ‘d(_#ind)’, ‘s(_#ind)’, ‘wh(_#ind)’, ‘whd(_#ind)’ and ‘whds(_#ind)’ instead of the corresponding constant variables.
      • if(condition,expr_then,_expr_else)’: return value of ‘expr_then’ or ‘expr_else’, depending on the value of ‘condition(0=false, other=true). ‘expr_else’ can be omitted in which case 0 is returned if the condition does not hold. Using the ternary operator ‘condition?expr_then[:expr_else]’ gives an equivalent expression. For instance, expressions ‘if(x%10==0,255,i)’ and ‘x%10?i:255’ both draw blank vertical lines on every 10th column of an image.
      • dowhile(expression,_condition)’ repeats the evaluation of ‘expression’ until ‘condition’ vanishes (or until ‘expression’ vanishes if no ‘condition’ is specified). For instance, the expression: ‘if(N<2,N,n=N-1;F0=0;F1=1;dowhile(F2=F0+F1;F0=F1;F1=F2,n=n-1))’ returns the Nth value of the Fibonacci sequence, for N>=0 (e.g., 46368 for N=24). ‘dowhile(expression,condition)’ always evaluates the specified expression at least once, then check for the loop condition. When done, it returns the last value of ‘expression’.
      • for(init,condition,_procedure,body)’ first evaluates the expression ‘init’, then iteratively evaluates ‘body’ (followed by ‘procedure’ if specified) while ‘condition’ is verified (i.e. not zero). It may happen that no iteration is done, in which case the function returns nan. Otherwise, it returns the last value of ‘body’. For instance, the expression: ‘if(N<2,N,for(n=N;F0=0;F1=1,n=n-1,F2=F0+F1;F0=F1;F1=F2))’ returns the Nth value of the Fibonacci sequence, for N>=0 (e.g., 46368 for N=24).
      • whiledo(condition,expression)’ is exactly the same as ‘for(init,condition,expression)’ without the specification of an initializing expression.
      • break()’ and ‘continue()’ respectively breaks and continues the current running bloc (loop, init or main environment).
      • date(attr,path)’ returns the date attribute for the given ‘path’ (file or directory), with ‘attr’ being { 0=year | 1=month | 2=day | 3=day of week | 4=hour | 5=minute | 6=second }, or a vector of those values.
      • date(_attr) returns the specified attribute for the current (locale) date.
      • print(expr1,expr2,...) or’print(#ind) prints the value of the specified expressions (or image information) on the console, and returns the value of the last expression (or nan in case of an image). Function ‘prints(expr)’ also prints the string composed of the ascii characters defined by the vector-valued expression (e.g. ‘prints('Hello')’).
      • debug(expression) prints detailed debug information about the sequence of operations done by the math parser to evaluate the expression (and returns its value).
      • display(_X,_w,_h,_d,_s) or’display(#ind) display the contents of the vector ‘X’ (or specified image) and wait for user events. if no arguments are provided, a memory snapshot of the math parser environment is displayed instead.
      • init(expression) and’end(expression) evaluates the specified expressions only once, respectively at the beginning and end of the evaluation procedure, and this, even when multiple evaluations are required (e.g. in ‘fill init(foo=0);++foo’).
      • copy(dest,src,_nb_elts,_inc_d,_inc_s,_opacity) copies an entire memory block of’nb_elts’ elements starting from a source value ‘src’ to a specified destination ‘dest’, with increments defined by ‘inc_d’ and ‘inc_s’ respectively for the destination and source pointers.
      • unref(a,b,...) destroys references to the named variable given as arguments.
      • stats(_#ind) returns the statistics vector of the running image [ind], i.e the vector [ im,iM,ia,iv,xm,ym,zm,cm,xM,yM,zM,cM,is,ip ] (14 values).
      • _(expr) just ignores its arguments (mainly useful for debugging).
    • User-defined macros:
      • Custom macro functions can be defined in a math expression, using the assignment operator ‘=’, e.g. ‘foo(x,y) = cos(x + y); result = foo(1,2) + foo(2,3)’.
      • Trying to override a built-in function (e.g. ‘abs()’) has no effect.
      • Overloading macros with different number of arguments is possible. Re-defining a previously defined macro with the same number of arguments discards its previous definition.
      • Macro functions are indeed processed as macros by the mathematical evaluator. You should avoid invoking them with arguments that are themselves results of assignments or self-operations. For instance, ‘foo(x) = x + x; z = 0; foo(++z)’ returns ‘4’ rather than expected value ‘2’.
      • When substituted, macro arguments are placed inside parentheses, except if a number sign ‘#’ is located just before or after the argument name. For instance, expression ‘foo(x,y) = x*y; foo(1+2,3)’ returns ‘9’ (being substituted as ‘(1+2)*(3)’), while expression ‘foo(x,y) = x#*y#; foo(1+2,3)’ returns ‘7’ (being substituted as ‘1+2*3’).
      • Number signs appearing between macro arguments function actually count for ‘empty’ separators. They may be used to force the substitution of macro arguments in unusual places, e.g. as in ‘str(N) = ['I like N#'];’.
    • Multi-threaded and in-place evaluation:
      • If your image data are large enough and you have several CPUs available, it is likely that the math expression passed to a ‘fill’ or ‘input’ command is evaluated in parallel, using multiple computation threads.
      • Starting an expression with ‘:’ or ‘*’ forces the evaluations required for an image to be run in parallel, even if the amount of data to process is small (beware, it may be slower to evaluate in this case!). Specify ‘:’ (instead of ‘*’) to avoid possible image copy done before evaluating the expression (this saves memory, but do this only if you are sure this step is not required!)
      • If the specified expression starts with ‘>’ or ‘<’, the pixel access operators ‘i()’, ‘i[]’, ‘j()’ and ‘j[]’ return values of the image being currently modified, in forward (‘>’) or backward (‘<’) order. The multi-threading evaluation of the expression is also disabled in this case.
      • Function ‘critical(operands)’ forces the execution of the given operands in a single thread at a time.
    • Expressions ‘i(_#ind,x,_y,_z,_c)=value’, ‘j(_#ind,x,_y,_z,_c)=value’, ‘i[_#ind,offset]=value’ and ‘j[_#ind,offset]=value’ set a pixel value at a different location than the running one in the image [ind] (or in the associated image if argument ‘#ind’ is omitted), either with global coordinates/offsets (with ‘i(...)’ and ‘i[...]’), or relatively to the current position (x,y,z,c) (with ‘j(...)’ and ‘j[...]’). These expressions always return ‘value’.

Glow node

pluginIcon

This documentation is for version 1.0 of Glow (fr.inria.Glow).

Description

A glow effect based on the bloom filter node. The mask input limits the area where the glowing elements are. It does not cut off the shine produced by the glow.

For more interesting looks there are some additional features like stretch, rotation and postgrade.

Parameter / script name Type Default Function
Convert to Group / convertToGroup Button   Converts this node to a Group: the internal node-graph and the user parameters will become editable
Isolate Highlights / isolateHighlights Double 0.25
“Isolate Highlights” controls on which parts of the image the glow is applied.

high value -> only bright areas
Isolate Hue / isolateHue Boolean Off If checked, the picked hue will additionally limit the areas of the glow.
pick Hue / HSVTool1srcColor Color r: 0 g: 0 b: 0
Pick a color in the viewport to isolate it’s hue.

The glow will only be applied to those areas, if ‘Isolate Hue’ is checked.
GlowMap Preview / preview Boolean Off When checked, the output will be the glowmap. Use this as a preview to adjust the highlight and hue isolation.
Size / size Double 3 This will change the size of the glow.
Ratio / BloombloomRatio Double 2  
Iterations / iterations Integer 7 Number of blur kernels of the bloom filter. The original implementation uses a value of 5. Higher values give a wider of heavier tail (the size of the largest blur kernel is 2**bloomCount*size). A count of 1 is just the original blur.
Filter / Bloomfilter Choice Quasi-Gaussian
Bluring filter. The quasi-Gaussian filter should be appropriate in most cases. The Gaussian filter is more isotropic (its impulse response has rotational symmetry), but slower.
Quadratic might also look a bit better, but it is slower, too.
Quasi-Gaussian (quasigaussian): Quasi-Gaussian filter (0-order recursive Deriche filter, faster) - IIR (infinite support / impulsional response).
Gaussian (gaussian): Gaussian filter (Van Vliet recursive Gaussian filter, more isotropic, slower) - IIR (infinite support / impulsional response).
Box (box): Box filter - FIR (finite support / impulsional response).
Triangle (triangle): Triangle/tent filter - FIR (finite support / impulsional response).
Quadratic (quadratic): Quadratic filter - FIR (finite support / impulsional response).
Stretch / stretch Double 0
Stretch the glow!

0 -> uniform proportions
1 -> blur only in one direction
Rotate / rotate Double 0 This will rotate your stretched glow. If “Stretch” is 0 it won’t have any effect.
Gain / PostGradeMasterGain Color r: 1 g: 1 b: 1 a: 1  
Gamma / PostGradeMasterGamma Color r: 1 g: 1 b: 1 a: 1  
Saturation / PostGradeMasterSaturation Color r: 1 g: 1 b: 1 a: 1  
Screen / screen Boolean Off
If checked, the bloomed image will be screened on top of the input image. This helps to preserve the highlights in your image.

By default it is added on top of the imput image. (plus)
Add Input / addInput Boolean Off Add the input image to the bloomed one.
Glow Only / glowOnly Boolean Off
The output will only be the glow effect itself.

You can add it on top of your source with a plus-merge or a screen-merge, later.
expand RoD / expRoD Boolean Off
By default the Region of Definition (RoD) will be cropped to the input RoD.
Use this option, if you want the glow effect to be available even outside your input format, and thus being not cropped.
As the blur sizes of the bloom node can get very big, this may lead to a very big RoD! Especially, if you use a lot of iterations.
apply on alpha / alpha Boolean Off Controls if the glow is applied to the alpha channel, too.

GodRays node

pluginIcon

This documentation is for version 1.0 of GodRays (net.sf.openfx.GodRays).

Description

Average an image over a range of transforms.

This can be used to create crepuscular rays (also called God rays) by setting the scale and center parameters: scale governs the length of rays, and center should be set to the Sun or light position (which may be outside of the image).

Setting toColor to black and gamma to 1 causes an exponential decay which is very similar to the real crepuscular rays.

This can also be used to create directional blur using a fixed number of samples (as opposed to DirBlur, which uses an adaptive sampling method).

This plugin concatenates transforms upstream.

Inpaint node

pluginIcon

This documentation is for version 1.0 of Inpaint (eu.cimg.Inpaint).

Description

Inpaint (a.k.a. content-aware fill) the areas indicated by the Mask input using patch-based inpainting.

Be aware that this filter may produce different results on each frame of a video, even if there is little change in the video content. To inpaint areas with lots of details, it may be better to inpaint on a single frame and paste the inpainted area on other frames (if a transform is also required to match the other frames, it may be computed by tracking).

A tutorial on using this filter can be found at http://blog.patdavid.net/2014/02/getting-around-in-gimp-gmic-inpainting.html

The algorithm is described in the two following publications:

“A Smarter Examplar-based Inpainting Algorithm using Local and Global Heuristics for more Geometric Coherence.” (M. Daisy, P. Buyssens, D. Tschumperlé, O. Lezoray). IEEE International Conference on Image Processing (ICIP’14), Paris/France, Oct. 2014

and

“A Fast Spatial Patch Blending Algorithm for Artefact Reduction in Pattern-based Image Inpainting.” (M. Daisy, D. Tschumperlé, O. Lezoray). SIGGRAPH Asia 2013 Technical Briefs, Hong-Kong, November 2013.

Uses the ‘inpaint’ plugin from the CImg library.

Matrix3x3 node

This documentation is for version 1.0 of Matrix3x3 (eu.cimg.CImgMatrix3x3).

Description

Compute the convolution of the input image with the specified matrix.

This works by multiplying each surrounding pixel of the input image with the corresponding matrix coefficient (the current pixel is at the center of the matrix), and summing up the results.

For example [-1 -1 -1] [-1 8 -1] [-1 -1 -1] produces an edge detection filter (which is an approximation of the Laplacian filter) by multiplying the center pixel by 8 and the surrounding pixels by -1, and then adding the nine values together to calculate the new value of the center pixel.

Uses the CImg library.

Shadertoy node

pluginIcon

This documentation is for version 1.0 of Shadertoy (net.sf.openfx.Shadertoy).

Description

Apply a Shadertoy fragment shader.

This plugin implements Shadertoy 0.8.8, but multipass shaders and sound are not supported. Some multipass shaders can still be implemented by chaining several Shadertoy nodes, one for each pass.

Shadertoy 0.8.8 uses WebGL 1.0 (a.k.a. GLSL ES 1.0 from GLES 2.0), based on GLSL 1.20

Note that the more recent Shadertoy 0.9.1 uses WebGL 2.0 (a.k.a. GLSL ES 3.0 from GLES 3.0), based on GLSL 3.3

This help only covers the parts of GLSL ES that are relevant for Shadertoy. For the complete specification please have a look at GLSL ES 1.0 specification or pages 3 and 4 of the OpenGL ES 2.0 quick reference card. See also the Shadertoy/GLSL tutorial.

Image shaders

Image shaders implement the mainImage() function in order to generate the procedural images by computing a color for each pixel. This function is expected to be called once per pixel, and it is responsibility of the host application to provide the right inputs to it and get the output color from it and assign it to the screen pixel. The prototype is:

void mainImage( out vec4 fragColor, in vec2 fragCoord );

where fragCoord contains the pixel coordinates for which the shader needs to compute a color. The coordinates are in pixel units, ranging from 0.5 to resolution-0.5, over the rendering surface, where the resolution is passed to the shader through the iResolution uniform (see below).

The resulting color is gathered in fragColor as a four component vector.

How-to
  • Use structs: struct myDataType { float occlusion; vec3 color; }; myDataType myData = myDataType(0.7, vec3(1.0, 2.0, 3.0));
  • Initialize arrays: arrays cannot be initialized in WebGL.
  • Do conversions: int a = 3; float b = float(a);
  • Do component swizzling: vec4 a = vec4(1.0,2.0,3.0,4.0); vec4 b = a.zyyw;
  • Access matrix components: mat4 m; m[1] = vec4(2.0); m[0][0] = 1.0; m[2][3] = 2.0;
Be careful!
  • the f suffix for floating point numbers: 1.0f is illegal in GLSL. You must use 1.0
  • saturate(): saturate(x) doesn’t exist in GLSL. Use clamp(x,0.0,1.0) instead
  • pow/sqrt: please don’t feed sqrt() and pow() with negative numbers. Add an abs() or max(0.0,) to the argument
  • mod: please don’t do mod(x,0.0). This is undefined in some platforms
  • variables: initialize your variables! Don’t assume they’ll be set to zero by default
  • functions: don’t call your functions the same as some of your variables

Shadertoy Outputs

For image shaders, fragColor is used as output channel. It is not, for now, mandatory but recommended to leave the alpha channel to 1.0.

For sound shaders, the mainSound() function returns a vec2 containing the left and right (stereo) sound channel wave data.

OpenFX extensions to Shadertoy

Shadertoy was extended to:

  • Expose shader parameters as uniforms, which are presented as OpenFX parameters.
  • Provide the description and help for these parameters directly in the GLSL code.
  • Add a default uniform containing the render scale. In OpenFX, a render scale of 1 means that the image is rendered at full resolution, 0.5 at half resolution, etc. This can be used to scale parameter values so that the final aspect does not depend on the render scale. For example, a blur size parameter given in pixels at full resolution would have to be multiplied by the render scale.
  • Add a default uniform containing the offset of the processed texture with respect to the position of the origin.

The extensions are:

  • The pre-defined iRenderScale uniform contains the current render scale. Basically all pixel sizes must be multiplied by the renderscale to get a scale-independent effect. For compatibility with Shadertoy, the first line that starts with const vec2 iRenderScale is ignored (the full line should be const vec2 iRenderScale = vec2(1.,1.);).
  • The pre-defined iChannelOffset uniform contains the texture offset for each channel relative to channel 0. For compatibility with Shadertoy, the first line that starts with const vec2 iChannelOffset is ignored (the full line should be const vec2 iChannelOffset[4] = vec2[4]( vec2(0.,0.), vec2(0.,0.), vec2(0.,0.), vec2(0.,0.) );).
  • The shader may define additional uniforms, which should have a default value, as in uniform vec2 blurSize = vec2(5., 5.);. These uniforms can be made available as OpenFX parameters using settings in the ‘Extra parameters’ group, which can be set automatically using the ‘Auto. Params’ button (automatic parameters are only updated if the node is connected to a Viewer). A parameter label and help string can be given in the comment on the same line. The help string must be in parenthesis. uniform vec2 blurSize = vec2(5., 5.); // Blur Size (The blur size in pixels.) min/max values can also be given after a comma. The strings must be exactly min= and max=, without additional spaces, separated by a comma, and the values must have the same dimension as the uniform: uniform vec2 blurSize = vec2(5., 5.); // Blur Size (The blur size in pixels.), min=(0.,0.), max=(1000.,1000.)
  • The following comment line placed in the shader gives a label and help string to input 1 (the comment must be the only thing on the line): // iChannel1: Noise (A noise texture to be used for random number calculations. The texture should not be frame-varying.)
  • This one also sets the filter and wrap parameters: // iChannel0: Source (Source image.), filter=linear, wrap=clamp
  • And this one sets the output bounding box (possible values are Default, Union, Intersection, and iChannel0 to iChannel3): // BBox: iChannel0
Converting a Shadertoy for use in OpenFX

To better understand how to modify a Shadertoy for OpenFX, let use take the simple Gaussian blur example, which is also available as a preset in the Shadertoy node.

In Natron, create a new project, create a Shadertoy node, connect the input 1 of the Viewer to the output of the Shadertoy node. This should give you a blurry color image that corresponds to the default Shadertoy source code. The Shadertoy node should have four inputs, named “iChannel0” to “iChannel3”.

In the Shadertoy node parameters, open the “Image Shader” group. You should see the GLSL source code. Now in the “Load from Preset” choice, select “Blur/Gaussian Blur”. The viewer should display a black image, but you should also notice that the Shadertoy node now has two visible inputs: “Source” and “Modulate” (in Nuke, these inputs are still called iChannel0 and iChannel1). Create a Read node that reads a still image or a video, and connect it to the “Source” input. A blurred version of the image should now appear in the viewer. You should also notice that two parameters appeared at the top of the parameters for the Shadertoy node: “Size” and “Modulate”. Play with the “Size” parameter and see how it affects the blur size (you may have to zoom on the image to see precisely the effect).

Now let us examine the modifications that were brought to the original GLSL code:

These three comment lines describe the label, filter, and wrap parameters for each input, as well as the size of the output bounding box (also called “region of definition”):

// iChannel0: Source, filter=linear, wrap=clamp
// iChannel1: Modulate (Image containing a factor to be applied to the Blur size in the first channel), filter=linear, wrap=clamp
// BBox: iChannel0

Two constant global variables were added, which are ignored by the Shadertoy plugin, so that you can still copy-and-paste the source code in Shadertoy 0.8.8 and it still works (unfortunately, it does not work anymore with later versions of Shadertoy). You can safely ignore these:

const vec2 iRenderScale = vec2(1.,1.);
const vec2 iChannelOffset[4] = vec2[4]( vec2(0.,0.), vec2(0.,0.), vec2(0.,0.), vec2(0.,0.) );

Then the uniform section gives the list of what will appear as OpenFX parameters, together with their default value, label, help string, and default range. Note that in the original Shadertoy code, the blur size was a constant hidden inside the code. Finding out the parameters of a Shadertoy requires precise code inspection. If you modify this part of the code, pressing the “Auto. Params” button will apply these changes to the OpenFX parameters:

uniform float size = 10.; // Size (Size of the filter kernel in pixel units. The standard deviation of the corresponding Gaussian is size/2.4.), min=0., max=21.
uniform bool perpixel_size = false; // Modulate (Modulate the blur size by multiplying it by the first channel of the Modulate input)

In the mainImage function, which does the processing, we compute the mSize and kSize variables, which are the kernel size and mask size for that particular algorithm, from the “Size” parameter, multiplied by the render scale to get a scale-invariant effect. If the “Modulate” check box is on, we also multiply the size by the value found in the first channel (which is red, not alpha) of the “Modulate” input, which is in the iChannel1 texture according to the comments at the beginning of the source code. This can be use to modulate the blur size depending on the position in the image. The “Modulate” input may be for example connected to the output of a Roto node (with the “R” checkbox checked in the Roto node). Since the Roto output may not have the same size and origin as the Source image, we take care of these by using the iChannelOffset and iChannelResolution values for input 1.

float fSize = size * iRenderScale.x;
if (perpixel_size) {
  fSize *= texture2D(iChannel1, (fragCoord.xy-iChannelOffset[1].xy)/iChannelResolution[1].xy).x;
}
int kSize = int(min(int((fSize-1)/2), KSIZE_MAX));
int mSize = kSize*2+1;

In the rest of the code, the only difference is that the blur size is not constant and equal to 7, but comes from the fSize variable:

float sigma = fSize / 2.4;
Issues with Gamma correction

OpenGL processing supposes all textures are linear, i.e. not gamma-compressed. This for example about bilinear interpolation on textures: this only works if the intensities are represented linearly. So a proper OpenGL rendering pipe should in principle:

  1. Convert all textures to a linear representation (many 8-bit textures are gamma-compressed)
  2. Render with OpenGL
  3. Gamma-compress the linear framebuffer for display

When processing floating-point buffers in OpenFX, the color representation is usually linear, which means that the OpenFX host usually performs steps 1 and 3 anyway (that includes Natron and Nuke): the images given to an OpenFX plugins are in linear color space, and their output is also supposed to be linear.

However, many OpenGL applications, including Shadertoy and most games, skip steps 1 and 3 (mainly for performance issue): they process gamma-compressed textures as if they were linear, and sometimes have to boost their output by gamma compression so that it looks nice on a standard display (which usually accepts a sRGB-compressed framebuffer).

This is why many shaders from Shadertoy convert their output from linear to sRGB or gamma=2.2, see for example the srgb2lin and lin2srgb functions in https://www.shadertoy.com/view/XsfXzf . These conversions must be removed when using the shader in OpenFX.

An alternative solution would be to convert all Shadertoy inputs from linear to sRGB, and convert back all outputs to linear, either inside the Shadertoy node, or using external conversion nodes (such as OCIOColorSpace). But this is a bad option, because this adds useless processing. Removing the srgb2lin and lin2srgb conversions from the shader source is a much better option (these functions may have different names, or there may simply be operations line pow(c,vec3(2.2)) and/or pow(c,vec3(1./2.2)) in the GLSL code).

As an example, take a look at the changes made to the Barrel Blur Chroma Shadertoy: the OpenFX version is available as a preset in the Shadertoy node as “Effects/Barrel Blur Chroma”. When it was converted to OpenFX, all gamma compression and decompression operations were identified and removed.

Multipass shaders

Most multipass shaders (those using BufA, BufB, BufC, or BufD) can be implemented using the Shadertoy plugin.

The shader sources for two sample multipass shadertoys are available as Natron PyPlugs (but the shader sources are also available separately next to the PyPlugs if you want to use these in another OpenFX host:

The principle is very simple: since multipass cannot be done using a single Shadertoy, use several Shadertoy nodes, route the textures between them, and link the parameters. You can learn from these two examples. To figure out the route between textures, click on the tab for each shader in shadertoy.com, and check which shader output is connected to the input textures (iChannel0, etc.) for this shader. The connections between nodes should follow these rules.

The only multipass effects that can not be implemented are the shaders that read back the content of a buffer to compute that same buffer, because compositing graphs cannot have loops (the execution of such a graph would cause an infinite recursion). One example is this progressive lightmap render, where BufB from the previous render is read back as iChannel1 in the BufB shader.

Default textures and videos

The default shadertoy textures and videos are available from the Shadertoy web site. In order to mimic the behavior of each shader, download the corresponding textures or videos and connect them to the proper input.

Despill node

pluginIcon

This documentation is for version 1.0 of Despill (net.sf.openfx.Despill).

Description

Remove the unwanted color contamination of the foreground (spill) caused by the reflected color of the bluescreen/greenscreen.

While a despill operation often only removes green (for greenscreens) this despill also enables adding red and blue to the spill area. A lot of Keyers already have implemented their own despill methods. However, in a lot of cases it is useful to separate the keying process in 2 tasks to get more control over the final result. Normally these tasks are the generation of the alpha mask and the spill correction. The generated alpha Mask (Key) is then used to merge the despilled forground over the new background.

This effect is based on the unspill operations described in section 4.5 of “Digital Compositing for Film and Video” by Steve Wright (Focal Press).

Inputs

Keyer node

pluginIcon

This documentation is for version 1.0 of Keyer (net.sf.openfx.KeyerPlugin).

Description

A collection of simple keyers. These work by computing a foreground key from the RGB values of the input image (see the keyerMode parameter).

This foreground key is is a scalar from 0 to 1. From the foreground key, a background key (or transparency) is computed.

The function that maps the foreground key to the background key is piecewise linear:

  • it is 0 below A = (center+toleranceLower+softnessLower)
  • it is linear between A = (center+toleranceLower+softnessLower) and B = (center+toleranceLower)

-it is 1 between B = (center+toleranceLower) and C = (center+toleranceUpper)

  • it is linear between C = (center+toleranceUpper) and D = (center+toleranceUpper+softnessUpper)
  • it is 0 above D = (center+toleranceUpper+softnessUpper)

Keyer can pull mattes that correspond to the RGB channels, the luminance and the red, green and blue colors. One very useful application for a luminance mask is to mask out a sky (almost always it is the brightest thing in a landscape).

Conversion from A, B, C, D to Keyer parameters is:

softnessLower = (A-B)

toleranceLower = (B-C)/2

center = (B+C)/2

toleranceUpper = (C-B)/2

softnessUpper = (D-C)

MatteMonitor node

This documentation is for version 1.0 of MatteMonitor (net.sf.openfx.MatteMonitorPlugin).

Description

A Matte Monitor: make alpha values that are strictly between 0 and 1 more visible.

After applying a Keyer, a scaling operation is usually applied to clean the matte. However, it is difficult to visualize on the output values that are very close to 0 or 1, but not equal. This plugin can be used to better visualize these values: connect it to the output of the scaling operator, then to a viewer, and visualize the alpha channel.

Alpha values lower or equal to 0 and greater or equal to 1 are leaved untouched, and alpha values in between are stretched towards 0.5 (using the slope parameter), making them more visible.

The output of this plugin should not be used for firther processing, but only for viewing.

The Matte Monitor is described in “Digital Compositing for Film and Video” by Steve Wright (Sec. 3.1).

PIK node

pluginIcon

This documentation is for version 1.0 of PIK (net.sf.openfx.PIK).

Description

A keyer that works by generating a clean plate from the green/blue screen sequences. Inspired by Nuke’s IBK by Paul Lambert and Fusion’s KAK by Pieter Van Houte.

There are 2 options to pull a key with PIK. One is to use PIKColor to automatically extract a clean plate from the foreground image and use it as the the C input, and the other is to pick a color which best represents the area you are trying to key.

The blue- or greenscreen image should be used as the Fg input, which is used to compute the output color. If that image contains significant noise, a denoised version should be used as the PFg input, which is used to pull the key. The C input should either be a clean plate or the output of PIKColor, and is used as the screen color if the ‘Screen Type’ is not ‘Pick’. The Bg image is used in calculating fine edge detail when either ‘Use Bg Luminance’ or ‘Use Bg Chroma’ is checked. Optionally, an inside mask (a.k.a. holdout matte or core matte) and an outside mask (a.k.a. garbage matte) can be connected to inputs InM and OutM. Note that the outside mask takes precedence over the inside mask.

If PIKcolor is used to build the clean plate, the PIKColor Source input should be the same as the PFg input to PIK, e.g. the denoised footage, and the inside mask of PIK can also be fed into the InM input of PIKColor.

The color weights deal with the hardness of the matte. When viewing the output (with screen subtraction checked), one may notice areas where edges have a slight discoloration due to the background not being fully removed from the original plate. This is not spill but a result of the matte being too strong. Lowering one of the weights will correct that particular edge. For example, if it is a red foreground image with an edge problem, lower the red weight. This may affect other edges so the use of multiple PIKs with different weights, split with KeyMixes, is recommended.

The Alpha Bias setting may be used either if there is a strong global color cast on the scene (e.g. the green or blue screen color is not pure), or if parts of the foreground are transparent in the output. This color is considered by the algorithm as being a grey reference: all colors from the PFg input are first normalized by this color before computation.

If the Alpha Bias is set, but the screen subtraction has a strong color bias (e.g. the despilled areas show the screen color), uncheck ‘Use Alpha for Despill’ and set the Despill Bias to the color of the foreground elements that are most affected by the color bias.

‘Screen Subtraction’ (a.k.a. despill) removes the background color from the output via a subtraction process (1-alpha times the screen color is subtracted at each pixel). When unchecked, the output is simply the original Fg premultiplied with the generated matte.

‘Use Bkg Luminance’ and ‘Use Bkg Chroma’ affect the output color by the new background. This feature can also sometimes really help with screens that exhibit some form of fringing artifact - usually a darkening or lightening of an edge on one of the color channels on the screen. The effect can be offset by grading the Bg input up or down with a grade node just before input. If it is just an area which needs help then just rotoscope that area and locally grade the Bg input up or down to remove the artifact.

The output of PIK is controlled by the “Output Mode” option. For example, if the output is “Premultiplied”, it should be composited with the background using a Merge-over operation.

The basic equation used to extract the key in PIK is (in the case of “green” keying):

alpha = 0 if (Ag-Ar*rw-Ab*gbw) is negative, else 1-(Ag-Ar*rw-Ab*gbw)/(Bg-Br*rw-Bb*gbw)

A is input PFg and B is input C, rw is the value of “Red Weight” and gbw is the value of “Green/Blue Weight”.

PIKColor node

pluginIcon

This documentation is for version 1.0 of PIKColor (fr.inria.PIKColor).

Description

This node provides the PIK per-pixel keyer a pseudo clean-plate to be used as color reference.

The idea is to remove the foreground image and only leave the shades and hues of the original blue/greenscreen.

Attach the output of this node to the ‘C’ input of a PIK node. Attach the input of this node and the ‘PFg’ input of PIK to the original screen, or preferably the denoised screen.

Pick which color your screen type is in both nodes and then while viewing the alpha output from PIK lower the darks.b (if a bluescreen - adjust darks.g if a greenscreen) in this node until you see a change in the garbage area of the matte. Once you see a change then you have gone too far -back off a step. If you are still left with discolored edges you can use the other colors in the lights and darks to eliminate them. Remember the idea is to be left with the original shades of the screen and the foreground blacked out. While swapping between viewing the matte from the PIK and the rgb output of PIKColor adjust the other colors until you see a change in the garbage area of the matte. Simple rule of thumb - if you have a light red discolored area increase the lights.r - if you have a dark green discolored area increase darks.g. If your screen does not have a very saturated hue you may still be left with areas of discoloration after the above process. The ‘erode’ slider can help with this - while viewing the rgb output adjust the erode until those areas disappear.

The ‘Patch Black’ slider allows you to fill in the black areas with screen color. This is not always necessary but if you see blue squares in your composite increase this value and it’ll fix it.

The optional ‘InM’ input can be used to provide an inside mask (a.k.a. core matte or holdout matte), which is excluded from the clean plate. If an inside mask is fed into the Keyer (PIK or another Keyer), the same inside mask should be fed inside PIKColor.

The above is the only real workflow for this node - working from the top parameter to the bottom parameter- going back to tweak darks/lights with ‘erode’ and ‘patch black’ activated is not really going to work.

KeyMix node

This documentation is for version 1.0 of KeyMix (net.sf.openfx.KeyMix).

Description

KeyMix takes two images and layers them together according to a third input. It can be used to lay a foreground over a background using the output of a keyer. The only disadvantage to this method is that it outputs an image with no alpha.

It copies the pixel from A to B only where the Mask is non-zero. It is the same as the Matte operation, but alpha for input A is taken from an external mask, and the output alpha is mixed between A and B. The output bounding box is the union of A and B.

As well as functioning as a layering node, it can also be used to integrate two color operations with one mask. This guards against ‘recycled masks’, where two consecutive color filters are masked using the same mask, which may generate strange artifacts.

Merge node

pluginIcon

This documentation is for version 1.0 of Merge (net.sf.openfx.MergePlugin).

Description

Pixel-by-pixel merge operation between two or more inputs. Input A is first merged with B (or with a black and transparent background if B is not connected), then A2, if connected, is merged with the intermediary result, then A3, etc.

A description of most operators is available in the W3C Compositing and Blending Level 1 Recommendation https://www.w3.org/TR/compositing-1/ and a complete explanation of the Porter-Duff compositing operators can be found in “Compositing Digital Images”, by T. Porter and T. Duff (Proc. SIGGRAPH 1984) http://keithp.com/~keithp/porterduff/p253-porter.pdf

Note that if an input with only RGB components is connected to A or B, its alpha channel is considered to be transparent (zero) by default, and the “A” checkbox for the given input is automatically unchecked, unless it is set explicitly by the user. In fact, most of the time, RGB images without an alpha channel are only used as background images in the B input, and should be considered as transparent, since they should not occlude anything. That way, the alpha channel on output only contains the opacity of elements that are merged with this background. In some rare cases, though, one may want the RGB image to actually be opaque, and can check the “A” checkbox for the given input to do so.

RotoMerge node

This documentation is for version 1.0 of RotoMerge (net.sf.openfx.MergeRoto).

Description

Pixel-by-pixel merge operation between two inputs using and external alpha component for input A. All channels from input A arge merged with those from B, using RotoMask as the alpha component for input A: the alpha channel from A is thus merged onto the alpha channel from B using the RotoMask as the alpha value (“a” in the formulas). This may be useful, for example, to “paint” alpha values from A onto the alpha channel of B using a given operation with an external alpha mask (which may be opaque even where the alpha channel of A is zero).

A description of most operators is available in the W3C Compositing and Blending Level 1 Recommendation https://www.w3.org/TR/compositing-1/ and a complete explanation of the Porter-Duff compositing operators can be found in “Compositing Digital Images”, by T.

Screen node

The Screen node is a convenience node identical to the Merge node, except that the operator is set to screen by default.

SeExpr node

pluginIcon

This documentation is for version 2.0 of SeExpr (fr.inria.openfx.SeExpr).

Description

Use the SeExpr expression language (by Walt Disney Animation Studios) to process images.

What is SeExpr?

SeExpr is a very simple mathematical expression language used in graphics software (RenderMan, Maya, Mudbox, Yeti).

See the SeExpr Home Page and SeExpr Language Documentation for more information.

SeExpr is licensed under the Apache License, Version 2.0, and is Copyright Disney Enterprises, Inc.

SeExpr vs. SeExprSimple

The SeExpr plugin comes in two versions:

  • SeExpr has a single vector expression for the color channels, and a scalar expression for the alpha channel. The source color is accessed through the Csvector, and alpha through the As scalar, as specified in the original SeExpr language.
  • SeExprSimple has one scalar expression per channel, and the source channels may also be accessed through scalars (r, g, b, a).
SeExpr extensions

A few pre-defined variables and functions were added to the language for filtering and blending several input images.

The following pre-defined variables can be used in the script:

  • x: X coordinate (in pixel units) of the pixel to render.
  • y: Y coordinate (in pixel units) of the pixel to render.
  • u: X coordinate (normalized in the [0,1] range) of the output pixel to render.
  • v: Y coordinate (normalized in the [0,1] range) of the output pixel to render.
  • sx, sy: Scale at which the image is being rendered. Depending on the zoom level of the viewer, the image might be rendered at a lower scale than usual. This parameter is useful when producing spatial effects that need to be invariant to the pixel scale, especially when using X and Y coordinates. (0.5,0.5) means that the image is being rendered at half of its original size.
  • par: The pixel aspect ratio.

To use custom variables that are pre-defined in the plug-in (scalars, positions and colors) you must reference them using their script-name in the expression. For example, the parameter x1 can be referenced using x1 in the script:

Cs + x1
Multi-instruction expressions

If an expression spans multiple instructions (usually written one per line), each instruction must end with a semicolon (‘;’). The last instruction of the expression is considered as the final value of the pixel (a RGB vector or an Alpha scalar, depending on the script), and must not be terminated by a semicolon. More documentation is available on the SeExpr website.

Accessing pixel values from other frames

The input frame range used to render a given output frame is computed automatically if the following conditions hold:

  • The frame parameter to cpixel/apixel must not depend on the color or alpha of a pixel, nor on the result of another call to cpixel/apixel

  • A call to cpixel/apixel must not depend on the color or alpha of a pixel, as in the following:

    if (As > 0.1) { src = cpixel(1,frame,x,y); } else { src = [0,0,0]; }

If one of these conditions does not hold, all frames from the specified input frame range are asked for.

SeExprSimple node

This documentation is for version 2.0 of SeExprSimple (fr.inria.openfx.SeExprSimple).

Description

Use the SeExpr expression language (by Walt Disney Animation Studios) to process images.

What is SeExpr?

SeExpr is a very simple mathematical expression language used in graphics software (RenderMan, Maya, Mudbox, Yeti).

See the SeExpr Home Page and SeExpr Language Documentation for more information.

SeExpr is licensed under the Apache License, Version 2.0, and is Copyright Disney Enterprises, Inc.

SeExpr vs. SeExprSimple

The SeExpr plugin comes in two versions:

  • SeExpr has a single vector expression for the color channels, and a scalar expression for the alpha channel. The source color is accessed through the Csvector, and alpha through the As scalar, as specified in the original SeExpr language.
  • SeExprSimple has one scalar expression per channel, and the source channels may also be accessed through scalars (r, g, b, a).
SeExpr extensions

A few pre-defined variables and functions were added to the language for filtering and blending several input images.

The following pre-defined variables can be used in the script:

  • x: X coordinate (in pixel units) of the pixel to render.
  • y: Y coordinate (in pixel units) of the pixel to render.
  • u: X coordinate (normalized in the [0,1] range) of the output pixel to render.
  • v: Y coordinate (normalized in the [0,1] range) of the output pixel to render.
  • sx, sy: Scale at which the image is being rendered. Depending on the zoom level of the viewer, the image might be rendered at a lower scale than usual. This parameter is useful when producing spatial effects that need to be invariant to the pixel scale, especially when using X and Y coordinates. (0.5,0.5) means that the image is being rendered at half of its original size.
  • par: The pixel aspect ratio.
  • cx, cy: Shortcuts for (x + 0.5)/par/sx and (y + 0.5)/sy, i.e. the canonical coordinates of the current pixel.
  • frame: Current frame being rendered
  • SeExprSimple only: r, g, b, a: RGBA channels (scalar) of the image from input 1.
  • SeExprSimple only: rN, gN, bN, aN: RGBA channels (scalar) of the image from input N, e.g. r2 and a2 are red and alpha channels from input 2.
  • Cs, As: Color (RGB vector) and alpha (scalar) of the image from input 1.
  • CsN, AsN: Color (RGB vector) and alpha (scalar) of the image from input N, e.g. Cs2 and As2 for input 2.
  • output_width, output_height: Dimensions of the output image being rendered.
  • input_width, input_height: Dimensions of image from input 1, in pixels.
  • input_widthN, input_heightN: Dimensions of image from input N, e.g. input_width2 and input_height2 for input 2.

The following additional functions are available:

  • color cpixel(int i, int f, float x, float y, int interp = 0): interpolates the color from input i at the pixel position (x,y) in the image, at frame f.
  • float apixel(int i, int f, float x, float y, int interp = 0): interpolates the alpha from input i at the pixel position (x,y) in the image, at frame f.

The pixel position of the center of the bottom-left pixel is (0., 0.).

The first input has index i=1.

interp controls the interpolation filter, and can take one of the following values:

  • 0: impulse - (nearest neighbor / box) Use original values
  • 1: bilinear - (tent / triangle) Bilinear interpolation between original values
  • 2: cubic - (cubic spline) Some smoothing
  • 3: Keys - (Catmull-Rom / Hermite spline) Some smoothing, plus minor sharpening (*)
  • 4: Simon - Some smoothing, plus medium sharpening (*)
  • 5: Rifman - Some smoothing, plus significant sharpening (*)
  • 6: Mitchell - Some smoothing, plus blurring to hide pixelation (*)(+)
  • 7: Parzen - (cubic B-spline) Greatest smoothing of all filters (+)
  • 8: notch - Flat smoothing (which tends to hide moire’ patterns) (+)

Some filters may produce values outside of the initial range (*) or modify the values even at integer positions (+).

  • x2 is the vertical amplitude in pixels.
  • x3 is the horizontal shift in pixels.
Custom parameters

To use custom variables that are pre-defined in the plug-in (scalars, positions and colors) you must reference them using their script-name in the expression. For example, the parameter x1 can be referenced using x1 in the script:

Cs + x1
Multi-instruction expressions

If an expression spans multiple instructions (usually written one per line), each instruction must end with a semicolon (‘;’). The last instruction of the expression is considered as the final value of the pixel (a RGB vector or an Alpha scalar, depending on the script), and must not be terminated by a semicolon. More documentation is available on the SeExpr website.

Accessing pixel values from other frames

The input frame range used to render a given output frame is computed automatically if the following conditions hold:

  • The frame parameter to cpixel/apixel must not depend on the color or alpha of a pixel, nor on the result of another call to cpixel/apixel

  • A call to cpixel/apixel must not depend on the color or alpha of a pixel, as in the following:

    if (As > 0.1) { src = cpixel(1,frame,x,y); } else { src = [0,0,0]; }

If one of these conditions does not hold, all frames from the specified input frame range are asked for.

Switch node

pluginIcon

This documentation is for version 1.0 of Switch (net.sf.openfx.switchPlugin).

Description

Lets you switch between any number of inputs.

The selected input number may be manually selected using the “which” parameter, or selected automatically if “automatic” is checked.

Automatic selection works by selecting, at any given time, the first input which is connected and has a non-empty region of definition.

A typical use case is a graph where an edited movie is used as input, then split into shots using one FrameRange plugin per shot (with “before” and “after” set to “Black”), followed by a different processing for each shot (e.g. stabilization, color correction, cropping), and all outputs are gathered into an edited movie using a single “Switch” plug-in in automatic mode. In this graph, no plug-in shifts time, and thus there is no risk of desynchronization, whereas using “AppendClip” instead of “Switch” may shift time if there is an error in one of the FrameRange ranges (a typical error is to use the same frame number as the last frame of shot n and the first frame of shot n+1).

This plugin concatenates transforms.

CornerPin node

pluginIcon

This documentation is for version 1.0 of CornerPin (net.sf.openfx.CornerPinPlugin).

Description

Allows an image to fit another in translation, rotation and scale.

The resulting transform is a translation if 1 point is enabled, a similarity if 2 are enabled, an affine transform if 3 are enabled, and a homography if they are all enabled.

An effect where an image transitions from a full-frame image to an image placed on a billboard or a screen, or a crash zoom effect, can be obtained by combining the Transform and CornerPin effects and using the Amount parameter on both effects.

Apply a CornerPin followed by a Transform effect (the order is important) and visualize the output superimposed on the target image. While leaving the value of the Amount parameter at 1, tune the Transform parameters (including Scale and Skew) so that the transformed image is as close as possible to the desired target location.

Then, adjust the ‘to’ points of the CornerPin effect (which should be affected by the Transform) so that the warped image perfectly matches the desired target location. Link the Amount parameter of the Transform and CornerPin effects.

Finally, by animating the Amount parameter of both effects from 0 to 1, the image goes progressively, and with minimal deformations, from full-frame to the target location, creating the desired effect (motion blur can be added on the Transform node, too).

Note that if only the CornerPin effect is used instead of combining CornerPin and Transform, the position of the CornerPin points is linearly interpolated between their ‘from’ position and their ‘to’ position, which may result in unrealistic image motion, where the image shrinks and expands, especially when the image rotates.

This plugin concatenates transforms.

While leaving the value of the Amount parameter at 1, tune the Transform parameters (including Scale and Skew) so that the transformed image is as close as possible to the desired target location.

Then, adjust the ‘to’ points of the CornerPin effect (which should be affected by the Transform) so that the warped image perfectly matches the desired target location. Link the Amount parameter of the Transform and CornerPin effects.

Finally, by animating the Amount parameter of both effects from 0 to 1, the image goes progressively, and with minimal deformations, from full-frame to the target location, creating the desired effect (motion blur can be added on the Transform node, too).

Note that if only the CornerPin effect is used instead of combining CornerPin and Transform, the position of the CornerPin points is linearly interpolated between their ‘from’ position and their ‘to’ position, which may result in unrealistic image motion, where the image shrinks and expands, especially when the image rotates.

This plugin concatenates transforms.

IDistort node

pluginIcon

This documentation is for version 2.0 of IDistort (net.sf.openfx.IDistort).

Description

Distort an image, based on a displacement map.

The U and V channels give the offset in pixels in the destination image to the pixel where the color is taken. For example, if at pixel (45,12) the UV value is (-1.5,3.2), then the color at this pixel is taken from (43.5,15.2) in the source image. This plugin concatenates transforms upstream, so that if the nodes upstream output a 3x3 transform (e.g. Transform, CornerPin, Dot, NoOp, Switch), the original image is sampled only once.

LensDistortion node

pluginIcon

This documentation is for version 4.0 of LensDistortion (net.sf.openfx.LensDistortion).

Description

Add or remove lens distortion, or produce an STMap that can be used to apply that transform.

The region of definition of the transformed image is computed from the region of definition of the Source input. If the input is defined outside of the project format, this may result in a very large region. A Crop effect may be inserted before LensDistortion to avoid this. If the input region of definition is inside the format, the Crop To Format parameter may be used to avoid expanding it.

LensDistortion can directly apply distortion/undistortion, but if the distortion parameters are not animated, the most efficient way to use LensDistortion and avoid repeated distortion function calculations is the following:

  • If the footage size is not the same as the project size, insert a FrameHold plugin between the footage to distort or undistort and the Source input of LensDistortion. This connection is only used to get the size of the input footage.
  • Set Output Mode to “STMap” in LensDistortion.
  • feed the LensDistortion output into the UV input of STMap, and feed the footage into the Source input of STMap.

Reformat node

pluginIcon

This documentation is for version 1.1 of Reformat (net.sf.openfx.Reformat).

Description

Convert the image to another format or size.

An image transform is computed that goes from the input format, regardless of the region of definition (RoD), to the selected format. The Resize Type parameter adjust the way the transform is computed.

The output format is set by this effect.

In order to set the output format without transforming the image content, use the NoOp effect.

This plugin concatenates transforms.

Resize Type / resize Choice Width
Format: Converts between formats, the image is resized to fit in the target format. Size: Scales to fit into a box of a given width and height. Scale: Scales the image.
None (none): Do not resize the original.
Width (width): Scale the original so that its width fits the output width, while preserving the aspect ratio.
Height (height): Scale the original so that its height fits the output height, while preserving the aspect ratio.
Fit (fit): Scale the original so that its smallest size fits the output width or height, while preserving the aspect ratio.

Resize node

pluginIcon

This documentation is for version 2.0 of Resize (fr.inria.openfx.OIIOResize).

Description

Resize input stream, using OpenImageIO.

Note that only full images can be rendered, so it may be slower for interactive editing than the Reformat plugin.

However, the rendering algorithms are different between Reformat and Resize: Resize applies 1-dimensional filters in the horizontal and vertical directins, whereas Reformat resamples the image, so in some cases this plugin may give more visually pleasant results than Reformat.

This plugin does not concatenate transforms (as opposed to Reformat).

STMap node

pluginIcon

This documentation is for version 2.0 of STMap (net.sf.openfx.STMap).

Description

Move pixels around an image, based on a UVmap.

The U and V channels give, for each pixel in the destination image, the normalized position of the pixel where the color is taken. (0,0) is the bottom left corner of the input image, while (1,1) is the top right corner. This plugin concatenates transforms upstream, so that if the nodes upstream output a 3x3 transform (e.g. Transform, CornerPin, Dot, NoOp, Switch), the original image is sampled only once.

This plugin concatenates transforms upstream.

SpriteSheet node

This documentation is for version 1.0 of SpriteSheet (net.sf.openfx.SpriteSheet).

Description

Read individual frames from a sprite sheet. A sprite sheet is a series of images (usually animation frames) combined into a larger image (or images). For example, an animation consisting of eight 100x100 images could be combined into a single 400x200 sprite sheet (4 frames across by 2 high). The sprite with index 0 is at the top-left of the source image, and sprites are ordered left-to-right and top-to-bottom. The output is an animated sprite that repeats the sprites given in the sprite range. The ContactSheet effect can be used to make a spritesheet from a series of images or a video.

Inputs
Input Description Optional
Source   No
Controls
Parameter / script name Type Default Function
Sprite Size / spriteSize Integer x: 64 y: 64 Size in pixels of an individual sprite.
Sprite Range / spriteRange Integer first: 0 last: 0 Index of the first and last sprite in the animation. The sprite index starts at zero.
Frame Offset / frameOffset Integer 1 Output frame number for the first sprite.

Tracker node

This documentation is for version 1.0 of Tracker (fr.inria.built-in.Tracker).

Description

Track one or more 2D point(s) using LibMV from the Blender open-source software.

Goal

Track one or more 2D point and use them to either make another object/image match-move their motion or to stabilize the input image.

Tracking
  • Connect a Tracker node to the image containing the item you need to track
  • Place tracking markers with CTRL+ALT+Click on the Viewer or by clicking the + button below the track table in the settings panel
  • Setup the motion model to match the motion type of the item you need to track. By default the tracker will only assume the item is underoing a translation. Other motion models can be used for complex tracks but may be slower.
  • Select in the settings panel or on the Viewer the markers you want to track and then start tracking with the player buttons on the top of the Viewer.
  • If a track is getting lost or fails at some point, you may refine it by moving the marker at its correct position, this will force a new keyframe on the pattern which will be visible in the Viewer and on the timeline.
Using the tracks data

You can either use the Tracker node itself to use the track data or you may export it to another node.

Using the Transform within the Tracker node

Go to the Transform tab in the settings panel, and set the Transform Type to the operation you want to achieve. During tracking, the Transform Type should always been set to None if you want to correctly see the tracks on the Viewer.

You will notice that the transform parameters will be set automatically when the tracking is finished. Depending on the Transform Type, the values will be computed either to match-move the motion of the tracked points or to stabilize the image.

Exporting the tracking data

You may export the tracking data either to a CornerPin node or to a Transform node. The CornerPin node performs a warp that may be more stable than a Transform node when using 4 or more tracks: it retains more information than the Transform node.

Inputs
Input Description Optional
Source   No
Controls
Parameter / script name Type Default Function
Motion Type / motionType Choice None
The type of motion in output of this node.
None: No transformation applied in output to the image: this node is a pass-through. Set it to this mode when tracking to correctly see the input image on the viewer
Stabilize: Transforms the image so that the tracked points do not move
Match-Move: Transforms a different image so that it moves to match the tracked points
Remove Jitter: Transforms the image so that the tracked points move smoothly with high frequencies removed
Add Jitter: Transforms the image by the high frequencies of the animation of the tracks to increase the shake or apply it on another image
Transform Type / transformType Choice CornerPin
The type of transform used to produce the results.
Transform: The tracks motion will be used to compute the translation, scale and rotation parameter of a Transform node. At least 1 track is required to compute the translation and 2 for scale and rotation. The more tracks you use, the more stable and precise the resulting transform will be.
CornerPin: The tracks motion will be used to compute a CornerPin. A CornerPin is useful if you are tracking an image portion that has a perspective distortion. At least 1 track is required to compute the homography transforming the “From” points to the “To” points, and 4 required to track a perspective transformation.The more points you add, the more stable and precise the resulting CornerPin will be.
Reference Frame / referenceFrame Integer 1 When exporting tracks to a CornerPin or Transform, this will be the frame number at which the transform will be an identity.
Set to Current Frame / setReferenceButton Button   Set the reference frame to the timeline’s current frame
Jitter Period / jitterPeriod Integer 10 Number of frames to average together to remove high frequencies for the add/remove jitter transform type
Smooth / smooth Integer t: 0 r: 0 s: 0 Smooth the translation/rotation/scale by averaging this number of frames together
Smooth / smoothCornerPin Integer 0 Smooth the CornerPin by averaging this number of frames together
Compute Transform Automatically / autoComputeransform Boolean On When checked, whenever changing a parameter controlling the Transform Generation (such as Motion Type, Transform Type, Reference Frame, etc…) or changing the Enabled parameter of a track, the transform parameters will be re-computed automatically. When unchecked, you must press the Compute button to compute it.
Compute / computeTransform Button   Click to compute the parameters of the Transform Controls or CornerPin Controls (depending on the Transform Type) from the data acquired on the tracks during the tracking. This should be done after the tracking is finished and when you feel the results are satisfying. For each frame, the resulting parameter is computed from the tracks that are enabled at this frame and that have a keyframe on the center point (e.g: are valid).
Robust Model / robustModel Boolean On When checked, the solver will assume that the model generated (i.e: the Transform or the CornerPin) is possible given the motion of the video and will eliminate points that do not match the model to compute the resulting parameters. When unchecked, the solver assumes that all points that are enabled and have a keyframe are valid and fit the model: this may in some situations work better if you are trying to find a model that is just not correct for the given motion of the video.
Fitting Error (px) / fittingError Double 0 This parameter indicates the error for each frame of the fitting of the model (i.e: Transform / CornerPin) to the tracks data. This value is in pixels and represents the rooted weighted sum of squared errors for each track. The error is essentially the difference between the point position computed from the original point onto which is applied the fitted model and the original tracked point.
Warn If Error Is Above / fittingErrorWarnAbove Double 1 A warning will appear if the model fitting error reaches this value (or higher). The warning indicates that the calculated model is probably poorly suited for the stabilization/match-move you want to achieve and you should either refine your tracking data or pick another model
Disable Transform / disableProcess Boolean Off When checked, the CornerPin/Transform applied by the parameters is disabled temporarily. This is useful if you are using a CornerPin and you need to edit the From or To points. For example, in match-move mode to replace a portion of the image by another one. To achieve such effect, you would need to place the From points of the CornerPin controls to the desired 4 corners in the image. Similarly, you may want to stabilize the image onto a moving vehicle, in which case you would want to set the CornerPin points to enclose the vehicle.
Set to Input Rod / setToInputRod Button   Set the 4 from points to the image rectangle in input of the tracker node
Export / export Button   Creates a node referencing the tracked data. The node type depends on the node selected by the Transform Type parameter. The type of transformation applied by the created node depends on the Motion Type parameter. To activate this button you must select set the Motion Type to something other than None
Mag. Window Size / magWindowSize Integer 200 The size of the selected track magnification winow in pixels

DiskCache node

This documentation is for version 1.0 of DiskCache (fr.inria.built-in.DiskCache).

Description

This node caches all images of the connected input node onto the disk with full 32bit floating point raw data. When an image is found in the cache, Natron will then not request the input branch to render out that image. The DiskCache node only caches full images and does not split up the images in chunks. The DiskCache node is useful if working with a large and complex node tree: this allows to break the tree into smaller branches and cache any branch that you’re no longer working on. The cached images are saved by default in the same directory that is used for the viewer cache but you can set its location and size in the preferences. A solid state drive disk is recommended for efficiency of this node. By default all images that pass into the node are cached but they depend on the zoom-level of the viewer. For convenience you can cache a specific frame range at scale 100% much like a writer node would do.

WARNING: The DiskCache node must be part of the tree when you want to read cached data from it.

Skewness quantifies how symmetrical the distribution is.
• A symmetrical distribution has a skewness of zero.
• An asymmetrical distribution with a long tail to the right (higher values) has a positive skew.
• An asymmetrical distribution with a long tail to the left (lower values) has a negative skew.
• The skewness is unitless.
• Any threshold or rule of thumb is arbitrary, but here is one: If the skewness is greater than 1.0 (or less than -1.0), the skewness is substantial and the distribution is far from symmetrical.
Kurtosis / statKurtosis Color r: 0 g: 0 b: 0 a: 0
Kurtosis quantifies whether the shape of the data distribution matches the Gaussian distribution.
•A Gaussian distribution has a kurtosis of 0.
•A flatter distribution has a negative kurtosis,
•A distribution more peaked than a Gaussian distribution has a positive kurtosis.
•Kurtosis has no units.
•The value that this plugin reports is sometimes called the excess kurtosis since the expected kurtosis for a Gaussian distribution is 0.0.
•An alternative definition of kurtosis is computed by adding 3 to the value reported by this plugin. With this definition, a Gaussian distribution is expected to have a kurtosis of 3.0.

Output node

This documentation is for version 1.0 of Output (fr.inria.built-in.Output).

Description

This node can only be used within a Group. There can only be 1 Output node in the group. It defines the output of the group.

Inputs
Input Description Optional
Source   No
Controls
Parameter / script name Type Default Function
       

Precomp node

This documentation is for version 1.0 of Precomp (fr.inria.built-in.Precomp).

Description

The Precomp node is like a Group node, but references an external Natron project (.ntp) instead.

This allows you to save a subset of the node tree as a separate project. A Precomp node can be useful in at least two ways:

It can be used to reduce portions of the node tree to pre-rendered image inputs. This speeds up render time: Natron only has to process the single image input instead of all the nodes within the project. Since this is a separate project, you also maintain access to the internal tree and can edit it any time.

It enables a collaborative project: while one user works on the main project, others can work on other parts referenced by the Precomp node.

Inputs
Input Description Optional
     
Controls
Parameter / script name Type Default Function
Project Filename (.ntp) / projectFilename N/A   The absolute file path of the project to use as a pre-comp.
Edit Project… / editProject Button   Opens the specified project in a new Natron instance
Pre-Render / preRender Boolean On
When checked the output of this node will be the images read directly from what is rendered by the node indicated by “Write Node”. If no Write is selected, or if the rendered images do not exist this node will have the behavior determined by the “On Error” parameter. To pre-render images, select a write node, a frame-range and hit “Render”.

When unchecked, this node will output the image rendered by the node indicated in the “Output Node” parameter by rendering the full-tree of the sub-project. In that case no writing on disk will occur and the images will be cached with the same policy as if the nodes were used in the active project in the first place.
Write Node / writeNode Choice   Choose here the Write node in the pre-comp from which to render images then specify a frame-range and hit the “Render” button.
First-Frame / first Integer 0 The first-frame to render
Last-Frame / last Integer 0 The last-frame to render
On Error / onError Choice Error
Indicates the behavior when an image is missing from the render of the pre-comp project
Load previous: Loads the previous frame in the sequence.
Load next: Loads the next frame in the sequence.
Load nearest: Loads the nearest frame in the sequence.
Error: Fails to render.
Black: Black Image.

Download External Data

This filter will download all external data files used by some filters of the G’MIC plug-in (Color Grading, Light Leaks, Grain, etc…), and will install them as persistent files on your hard drive. After this operation, you won’t need a permanent internet connection anymore in order to use some of the G’MIC filters.

Warning: A lot of data will be downloaded by this filter. This can take a long time !

Alternative (manual) method:

If, for any reasons, your plug-in is unable to retrieve data from the Internet, you can download all those data files manually (as a single .zip file) at this address :

https://gmic.eu/gmic_all_data.zip

You must then decompress all files contained in this archive at the following location:

  • for Unix-like systems : $HOME/.cache/gmic/
  • for Windows systems : %APPDATA/gmic/

Author: David Tschumperle. Latest Update: 2014/16/04.

Filter Design

G’MIC is an open image processing framework. Thus, including user-defined filters into this plug-in is possible.

To do so, you need to create a .gmic file in your $HOME/ folder (or %APPDATA%/user.gmic on Windows). It will be read each time the plug-in is launched, or when the Refresh button (under the central pane) is pressed. It must be a regular ascii file, containing the declarations and implementations of the filters (written in the G’MIC language) that will be added to the list of available ones.

Existing filters are already defined this way. Writing a filter from scratch in G’MIC requires some skills, but can be generally done in very few lines.

Example of a valid .gmic entry :

#@gmic_plugin My effect : my_effect, my_effect

Sigma = float(2,0,10)

my_effect :

\+blur $1 n 0,255 xor

Look at the reference documentation and the tutorial whose links are given below, to learn more. By the way, you are encouraged to share your nice custom filters with us on our forums, for inclusion into next releases of G’MIC.

Gmicky - Roddy

Gmicky is the name of the G’MIC mascot. He is a small and cute tiger who knows how to do magic. Gmicky is a tiger, i.e. fast, agile and elegant, just as the G’MIC code is :). As many magicians, Gmicky knows lot of gimmicks, and he is a direct and friendly companion of the ImageMagick’s wizard, or the GraphicMagick’s frog.

Roddy is another mascot designed specifically for the Artistic / Rodilius filter of G’MIC.

Gmicky and Roddy have been both created and drawn by

Mahvelous Mahvin: http://www.mahvin.com/

and

G’MIC CLUT from After Before Layers node

This documentation is for version 1.0 of G’MIC CLUT from After Before Layers (eu.gmic.CLUTfromAfterBeforeLayers).

Description

What is this filter for?

This filter requires at least two input layers to work properly.

It assumes you have an input top layer A and a base layer B such that A and B both represent the same image but with only color variations (typically A has been obtained from B using the color curves tool).

This filter is then able to estimate and outputs a color HaldCLUT H so that applying H on the base layer B gives back A.

This is useful when you have a color transformation between two images, that you want to recover and re-apply on a bunch of other images.

G’MIC Colorize Lineart Propagation node

This documentation is for version 1.0 of G’MIC Colorize Lineart Propagation (eu.gmic.ColorizeLineartPropagation).

Description

Layers ordering:

Note: You probably need to select All for the Input layers option on the left.

Color Spots = your layer with color indications.

Lineart = your layer with line-art (b&w or transparent).

Extrapolated Colors = the G’MIC generated layer with flat colors.

Warnings:

  • Do not rely too much on the preview, it is probably not accurate !

G’MIC Montage node

This documentation is for version 1.0 of G’MIC Montage (eu.gmic.Montage).

Description

Instructions:

  • Don’t forget to set the Input layers… option on the left if you have multiple input layers for your montage.
  • The Custom layout parameter is only active when Montage type is set to Custom layout. This is basically a string containing expressions such as:
\. H\(a,b\) or V\(a,b\) stand respectively for an horizontal and vertical merge of two blocks a and b\.

\. R\(a\), stands for a 90\-deg\. rotated version of a block a\. Use RR\(a\) and RRR\(a\) for resp\. 180\-deg and 270\-deg\. rotations\.

\. M\(a\), stands for a X\-mirrored version of a block a\. Use MRR\(a\) for a Y\-mirrored version of a\.
  • A block a can be a layer index or a nested montage expression itself.
  • Layer indices start from 0 (top layer) and are treated periodically.

NatronEngine

Detailed Description

Here are listed all classes being part of NatronEngine module. This module is always loaded by Natron natively, meaning access is granted to these classes in your scripts without importing anything.

AnimatedParam

Inherits Param

Inherited by: StringParamBase, PathParam, OutputFileParam, FileParam, StringParam, BooleanParam, ChoiceParam, ColorParam, DoubleParam, Double2DParam, Double3DParam, IntParam, Int2DParam, Int3DParam

Synopsis

This is the base class for all parameters which have the property canAnimate set to True. See the detailed description below

Functions
Detailed Description

Animating parameters have values that may change throughout the time. To enable animation the parameter should have at least 1 keyframe. Keyframes can be added in the derived class (since function signature is type specific) with the setValueAtTime function. Once 2 keyframes are active on the parameter, the value of the parameter will be interpolated automatically by Natron for a given time. You can control keyframes by adding,removing, changing their values and their KeyFrameTypeEnum type.

Note that by default new keyframes are always with a Smooth interpolation.

Moreover parameters can have Python expressions set on them to control their value. In that case, the expression takes precedence over any animation that the parameter may have, meaning that the value of the parameter would be computed using the expression provided.

Most of the functions to modify the value of the parameter take in parameter a view parameter. See this section for more informations.

Example:

# We assume the project has 2 views: the first named "Left" and the other named "Right"

# X and Y of the size parameter of the blur have now the value 3
Blur1.size.set(3,3)

# We split-off the "Right" view
Blur1.size.splitView("Right")

Blur1.size.set(5,5,"Right")

# The left view still has (3,3) but the right view now has (5,5)

Blur1.size.unSplitView("Right")

# Imagine now the project has 3 views: "Left" "Right" "Center"
# Only the "Right" view is split-off

# Setting the "Main" view will set "Left" + "Center"
Blur1.size.set(2,2, "Main")

# Note that this is the same as calling the following
# since by default all views that are not split off
# have the same value as the first view
Blur1.size.set(2,2, "Left")

# Calling the following will print an error
# because the view is not split
Blur1.size.set(2,2, "Center")

# The following call will set all views at once
Blur1.size.set(10,10, "All")

App

Inherits Group

Inherited by: GuiApp

Synopsis

The App object represents one instance of a project. See detailed description…

Functions
Detailed Description

An App object is created automatically every times a new project is opened. For each instance of Natron opened, there’s a new instance of App. You never create an App object by yourself, instead you can access them with variables that Natron pre-declared for you: The first instance will be named app1, the second app2,etc… See this section for an explanation of auto-declared variables.

When in background mode, (interpreter or render mode) there will always ever be a single App instance, so Natron will make the following assignment before running any other script:

app = app1

So you don’t have to bother on which instance you’re in. For Group Python plug-ins exported from Natron, they have a function with the following signature:

def createInstance(app,group):

So you don’t have to bother again on which App instance your script is run. You should only ever need to refer to the app1, app2… variables when using the Script Editor.

Finally, you can always access the App object of any instance by calling the following function when your script is for command line (background mode):

natron.getInstance(index)

Or the following function when you want to use GUI functionalities:

natron.getGuiInstance(index)

Warning

Note that in both cases, index is a 0-based number. So to retrieve app1 you would need to call the function with index = 0.

Creating nodes

The App object is responsible for creating new nodes. To create a node, you need to specify which plug-in you want to instantiate and optionally specify which major version should your node instantiate if the plug-in has multiple versions. For instance we could create a new Reader node this way:

reader = app.createNode("fr.inria.openfx.ReadOIIO")

You can also specify the group into which the node should be created, None being the project’s top level:

group = app.createNode("fr.inria.built-in.Group")
reader = app.createNode("fr.inria.openfx.ReadOIIO", -1, group)

For convenience, small wrapper functions have been made to directly create a Reader or Writer given a filename:

reader = app.createReader("/Users/me/Pictures/mySequence###.exr")
writer = app.createWriter("/Users/me/Pictures/myVideo.mov")

In case 2 plug-ins can decode/encode the same format, e.g. ReadPSD and ReadOIIO can both read .psd files, internally Natron picks the “best” OpenFX plug-in to decode/encode the image sequence/video according to the settings in the Preferences of Natron. If however you need a specific decoder/encoder to decode/encode the file format, you can use the getSettings() function with the exact plug-in ID.

In Natron you can call the following function to get a sequence with all plug-in IDs currently available:

natron.getPluginIDs()

You can also get a sub-set of those plug-ins with the getPluginIDs(filter) which returns only plug-in IDs containing the given filter (compared without case sensitivity).

Accessing the settings of Natron

To modify the parameters in the Preferences of Natron, you can call the getSettings() function to get an object containing all the parameters of the preferences.

Accessing the project settings

You can get a specific parameter of the project settings with the getProjectParam(name) function.

Member functions description
NatronEngine.App.addProjectLayer(layer)
Parameters:layerImageLayer

Appends a new project-wide layer. It will be available to all layer menus of all nodes. Each layer menu must be refreshed individually with either a right click on the menu or by changing nodes connections to get access to the new layer. Layer names are unique: even if you add duplicates to the layers list, only the first one in the list with that name will be available in the menus.

NatronEngine.App.addFormat(formatSpec)
Parameters:formatSpecstr

Attempts to add a new format to the project’s formats list. The formatSpec parameter must follow this spec: First the name of the format, without any spaces and without any non Python compliant characters; followed by a space and then the size of the format, in the form width*x*height; followed by a space and then the pixel aspect ratio of the format. For instance:

HD 1920x1080 1

Wrongly formatted format will be omitted and a warning will be printed in the ScriptEditor.

NatronEngine.App.createNode(pluginID[, majorVersion=-1[, group=None] [, properties=None]])
Parameters:
  • pluginIDstr
  • majorVersionint
  • groupGroup
  • propertiesDict
Return type:

Effect

Creates a new node instantiating the plug-in specified with the given pluginID at the given majorVersion. If majorVersion is -1, the highest version of the plug-in will be instantiated. The optional group parameter can be used to specify into which group the node should be created, None meaning the project’s top level.

In Natron you can call the following function to get a sequence with all plug-in IDs currently available:

natron.getPluginIDs()

The optional parameter properties is a dictionary containing properties that may modify the creation of the node, such as hiding the node GUI, disabling auto-connection in the NodeGraph, etc…

The properties are values of type Bool, Int, Float or String and are mapped against a unique key identifying them.

Most properties have a default value and don’t need to be specified, except the pluginID property.

Below is a list of all the properties available that are recognized by Natron. If you specify an unknown property, Natron will print a warning in the Script Editor.

All properties type have been wrapped to Natron types:

  • A boolean property is represented by the BoolNodeCreationProperty class
  • An int property is represented by the IntNodeCreationProperty class
  • A float property is represented by the FloatNodeCreationProperty class
  • A string property is represented by the StringNodeCreationProperty class

Here is an example on how to pass properties to the createNode function:

app.createNode("net.sf.cimg.CImgBlur", -1, app, dict([ ("CreateNodeArgsPropSettingsOpened", NatronEngine.BoolNodeCreationProperty(True)), ("CreateNodeArgsPropNodeInitialParamValues", NatronEngine.StringNodeCreationProperty("size")) ,("CreateNodeArgsPropParamValue_size",NatronEngine.FloatNodeCreationProperty([2.3,5.1])) ]))

NatronEngine.App.createReader(filename[, group=None] [, properties=None])
Parameters:
  • filenamestr
  • groupGroup
Return type:

Effect

Creates a reader to decode the given filename. The optional group parameter can be used to specify into which group the node should be created, None meaning the project’s top level.

In case 2 plug-ins can decode the same format, e.g. ReadPSD and ReadOIIO can both read .psd files, internally Natron picks the “best” OpenFX plug-in to decode the image sequence/video according to the settings in the Preferences of Natron. If however you need a specific decoder to decode the file format, you can use the getSettings() function with the exact plug-in ID.

NatronEngine.App.createWriter(filename[, group=None] [, properties=None])
Parameters:
  • filenamestr
  • groupGroup
Return type:

Effect

Creates a reader to decode the given filename. The optional group parameter can be used to specify into which group the node should be created, None meaning the project’s top level.

In case 2 plug-ins can encode the same format, e.g. WritePFM and WriteOIIO can both write .pfm files, internally Natron picks the “best” OpenFX plug-in to encode the image sequence/video according to the settings in the Preferences of Natron. If however you need a specific decoder to encode the file format, you can use the getSettings() function with the exact plug-in ID.

NatronEngine.App.getAppID()
Return type:int

Returns the zero-based ID of the App instance. app1 would have the AppID 0, app2 would have the AppID 1, and so on…

NatronEngine.App.getProjectParam(name)
Parameters:namestr
Return type:Param

Returns a project Param given its name (script-name). See this section for an explanation of script-name vs. label.

NatronEngine.App.getViewNames()
Return type:Sequence

Parameters:viewIndexint
Return type:str

Return the name of the view in the project settings corresponding to the view at the given viewIndex. Returns an empty view name if a corresponding view could not be found.

NatronEngine.App.render(effect, firstFrame, lastFrame[, frameStep])
Parameters:
  • effectEffect
  • firstFrameint
  • lastFrameint
  • frameStepint

Starts rendering the given effect on the frame-range defined by [firstFrame,*lastFrame*]. The frameStep parameter indicates how many frames the timeline should step after rendering each frame. The value must be greater or equal to 1. The frameStep parameter is optional and if not given will default to the value of the Frame Increment parameter in the Write node.

For instance:

render(effect,1,10,2)

Would render the frames 1,3,5,7,9

This is a blocking function only in background mode. A blocking render means that this function returns only when the render finishes (from failure or success).

This function should only be used to render with a Write node or DiskCache node.

NatronEngine.App.render(tasks)
Parameters:taskssequence

This function takes a sequence of tuples of the form (effect,firstFrame,lastFrame[,frameStep]) The frameStep is optional in the tuple and if not set will default to the value of the Frame Increment parameter in the Write node.

This is an overloaded function. Same as render(effect,firstFrame,lastFrame,frameStep) but all tasks will be rendered concurrently.

This function is called when rendering a script in background mode with multiple writers.

This is a blocking call only in background mode.

NatronEngine.App.redrawViewer(viewerNode)
Parameters:vieweNodeEffect

Just redraws the OpenGL viewer associated to the given viewerNode. The internal texture displayed will not be re-evaluated. If the node passed in parameter is not a viewer, this function has no effect.

NatronEngine.App.refreshViewer(viewerNode[, useCache])
Parameters:
  • vieweNodeEffect
  • useCachebool

Refresh the viewer texture. This causes a re-evaluation of the node-graph. If useCache is set to True, the render will not attempt to retrieve a texture from the cache if there is any. If the node passed in parameter is not a viewer, this function has no effect.

NatronEngine.App.timelineGetLeftBound()
Return type:int

Returns the left bound of the timeline, that is, the first member of the project’s frame-range parameter

NatronEngine.App.timelineGetRightBound()
Return type:int

Returns the right bound of the timeline, that is, the second member of the project’s frame-range parameter

NatronEngine.App.timelineGetTime()
Return type:int

Parameters:messagestr

Writes the given message to the Script Editor panel of Natron. This can be useful to inform the user of various information, warnings or errors.

NatronEngine.App.saveProject(filename)
Parameters:filenamestr
Return type:bool

This function returns True if it saved successfully, False otherwise.

NatronEngine.App.saveProjectAs(filename)
Parameters:filenamestr
Return type:bool

Save the project under the given filename. In GUI mode, if filename is empty, it prompts the user where to save the project.

This function returns True if it saved successfully, False otherwise.

NatronEngine.App.saveTempProject(filename)
Parameters:filenamestr
Return type:bool

Saves a copy of the project to the given filename without updating project properties such as the project path, last save time etc… This function returns True if it saved successfully, False otherwise.

NatronEngine.App.loadProject(filename)
Parameters:filenamestr
Return type:App

Loads the project indicated by filename. In GUI mode, this will open a new window only if the current window has modifications. In background mode this will close the current project of this App and open the project indicated by filename in it. This function returns the App object upon success, None otherwise.

NatronEngine.App.resetProject()
Return type:bool

Attempts to close the current project, without wiping the window. In GUI mode, the user is first prompted to saved his/her changes and can abort the reset, in which case this function will return False. In background mode this function always succeeds, hence always returns True. this always succeed.

NatronEngine.App.closeProject()
Return type:bool

Same as resetProject() except that the window will close in GUI mode. Also, if this is the last App alive, Natron will close.

NatronEngine.App.newProject()

BezierCurve

Inherits ItemBase

Synopsis

A BezierCurve is the class used for Beziers, ellipses and rectangles. See detailed description….

Functions
Detailed Description

A Bezier initially is in an opened state, meaning it doesn’t produce a shape yet. At this stage you can then add control points using the addControlPoint(x,y) function. Once you are done adding control points, call the function setCurveFinished(finished) to close the shape by connecting the last control point with the first.

Once finished, you can refine the Bezier curve by adding control points with the addControlPointOnSegment(index,t) function. You can then move and remove control points of the Bezier.

To get the position of the control points of the Bezier as well as the position of the feather points, use the functions getControlPointPosition and getFeatherPointPosition. The index passed to the function must be between 0 and getNumControlPoints -1.

If it lands on a keyframe of the Bezier shape, then the position at that keyframe is returned, otherwise the position is sampled between the surrounding keyframes.

To get a list of all keyframes time for a Bezier call the function getUserKeyframes().

Each property of a Bezier is a regular Param. All parameters can be retrieved with their script-name with the function getParam(scriptName).

Member functions description
NatronEngine.BezierCurve.addControlPoint(x, y[, view = "All"])
Parameters:
  • xfloat
  • yfloat
  • viewview

Adds a new control point to an opened shape (see isCurveFinished()) at coordinates (x,y). By default the feather point attached to this point will be equivalent to the control point. If the auto-keying is enabled in the user interface, then this function will set a keyframe at the timeline’s current time for this shape.

NatronEngine.BezierCurve.addControlPointOnSegment(index, t[, view = "All"])
Parameters:
  • indexPySide.QtCore.int
  • tPySide.QtCore.double
  • viewview

Adds a new control point to a closed shape (see isCurveFinished()). The index is the index of the Bezier segment linking the control points at index and index + 1. t is a value between [0,1] indicating the distance from the control point index the new control point should be. The closer to 1 t is, the closer the new control point will be to the control point at index +1. By default the feather point attached to this point will be equivalent to the control point.

If the auto-keying is enabled in the user interface, then this function will set a keyframe at the timeline’s current time for this shape.

NatronEngine.BezierCurve.getControlPointPosition(index, time[, view = "Main"])
Parameters:
  • indexint
  • timefloat
  • viewview
Return type:

PyTuple

Returns a tuple with the position of the control point at the given index as well as the position of its left and right tangents.

The tuple is encoded as such:

(x,y, leftTangentX, leftTangentY, rightTangentX, rightTangentY)

The position of the left and right tangents is absolute and not relative to (x,y).

The index passed to the function must be between 0 and getNumControlPoints -1. The time passed to the function corresponds to a time on the timeline’s in frames. If it lands on a keyframe of the Bezier shape, then the position at that keyframe is returned, otherwise the position is sampled between the surrounding keyframes.

To get a list of all keyframes time for a Bezier call the function getKeyframes().

NatronEngine.BezierCurve.getFeatherPointPosition(index, time[, view = "Main"])
Parameters:
  • indexint
  • timefloat
  • viewview
Return type:

PyTuple

Returns a tuple with the position of the feather point at the given index as well as the position of its left and right tangents.

The tuple is encoded as such:

(x,y, leftTangentX, leftTangentY, rightTangentX, rightTangentY)

The position of the left and right tangents is absolute and not relative to (x,y).

The index passed to the function must be between 0 and getNumControlPoints -1. The time passed to the function corresponds to a time on the timeline’s in frames. If it lands on a keyframe of the Bezier shape, then the position at that keyframe is returned, otherwise the position is sampled between the surrounding keyframes.

To get a list of all keyframes time for a Bezier call the function getKeyframes().

NatronEngine.BezierCurve.isActivated(time[, view="Main"])
Parameters:
  • timeint
  • viewstr

Effect

Inherits: Group , UserParamHolder

Synopsis

This object represents a single node in Natron, that is: an instance of a plug-in. See Detailed Description

Functions
Detailed Description

The Effect object can be used to operate with a single node in Natron. To create a new Effect, use the app.createNode(pluginID) function.

Natron automatically declares a variable to Python when a new Effect is created. This variable will have a script-name determined by Natron as explained in the Python Auto-declared variables section.

Once an Effect is instantiated, it declares all its Param and inputs. See how to manage user parameters below

To get a specific Param by script-name, call the getParam(name) function

Input effects are mapped against a zero-based index. To retrieve an input Effect given an index, you can use the getInput(inputNumber) function.

To manage inputs, you can connect them and disconnect them with respect to their input index with the connectInput(inputNumber,input) and then disconnectInput(inputNumber) functions.

If you need to destroy permanently the Effect, just call destroy().

For convenience some GUI functionalities have been made accessible via the Effect class to control the GUI of the node (on the node graph):

Creating user parameters

See this section

Member functions description
NatronEngine.Effect.addUserPlane(planeName, channels)
Parameters:
  • planeNamestr
  • channelssequence
Return type:

bool

Adds a new plane to the Channels selector of the node in its settings panel. When selected, the end-user can choose to output the result of the node to this new custom plane. The planeName will identify the plane uniquely and must not contain spaces or non python compliant characters. The channels are a sequence of channel names, e.g.:

addUserPlane(“MyLayer”,[“R”, “G”, “B”, “A”])

Note

A plane cannot contain more than 4 channels and must at least have 1 channel.

This function returns True if the layer was added successfully, False otherwise.

NatronEngine.Effect.beginChanges()

Starts a begin/End bracket, blocking all evaluation (=renders and callback onParamChanged) that would be issued due to a call to setValue on any parameter of the Effect.

Similarly all input changes will not be evaluated until endChanges() is called.

Typically to change several values at once we bracket the changes like this:

node.beginChanges()
param1.setValue(...)
param2.setValue(...)
param3.setValue(...)
param4.setValue(...)
node.endChanges()  # This triggers a new render

A more complex call:

node.beginChanges() node.connectInput(0,otherNode) node.connectInput(1,thirdNode) param1.setValue(…) node.endChanges() # This triggers a new render
NatronEngine.Effect.endChanges()

Ends a begin/end bracket. If the begin/end bracket recursion reaches 0 and there were calls made to setValue this function will effectively compresss all evaluations into a single one. See beginChanges()

NatronEngine.Effect.beginParametersUndoCommand(commandName)
Parameters:commandNamestr

Same as beginChanges() except that all parameter changes are gathered under the same undo/redo command and the user will be able to undo them all at once from the Edit menu. The commandName parameter is the text that will be displayed in the Edit menu.

NatronEngine.Effect.endParametersUndoCommand()

Close a undo/redo command that was previously opened with beginParametersUndoCommand().

NatronEngine.Effect.canConnectInput(inputNumber, node)
Parameters:
  • inputNumberint
  • nodeEffect
Return type:

bool

Returns whether the given node can be connected at the given inputNumber of this Effect. This function could return False for one of the following reasons:

  • The Effect already has an input at the given inputNumber
  • The node is None

Parameters:
  • timefloat
  • viewint
Return type:

RectD

NatronEngine.Effect.setColor(r, g, b)
Parameters:
  • rfloat
  • gfloat
  • bfloat

Set the color of the node as it appears on the node graph. Note that calling this function will in background mode will do nothing and should not be used.

NatronEngine.Effect.setLabel(name)

Warning

Using this function will remove any previous variable declared using the old script-name and will create a new variable with the new script name if valid.

If your script was using for instance a node named:

app1.Blur1

and you renamed it BlurOne, it should now be available to Python this way:

app1.BlurOne

but using app1.Blur1 would report the following error:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'Blur1' is not defined
NatronEngine.Effect.setSize(w, h)
Parameters:
  • wfloat
  • hfloat

Set the size of the node as it appears on the node graph. Note that calling this function will in background mode will do nothing and should not be used.

NatronEngine.Effect.setSubGraphEditable(editable)
Parameters:editablebool

Can be called to disable editing of the group via Natron’s graphical user interface. This is handy to prevent users from accidentally breaking the sub-graph. This can always be reverted by editing the python script associated. The user will still be able to see the internal node graph but will not be able to unlock it.

NatronEngine.Effect.setPagesOrder(pages)
Parameters:pagessequence

Given the string list pages try to find the corresponding pages by their-script name and order them in the given order.

NatronEngine.Effect.registerOverlay(overlay, params)
Parameters:
  • overlayPyOverlayInteract
  • paramsPyDict

This function takes in parameter a PyOverlayInteract and registers it as an overlay that will be drawn on the viewer when this node settings panel is opened.

The key of the params dict must match a key in the overlay’s parameters description returned by the function getDescription() of the PyOverlayInteract. The value associated to the key is the script-name of a parameter on this effect that should fill the role description returned by getDescription() on the overlay.

Note that overlays for a node will be drawn in the order they were registered by this function. To re-order them, you may call removeOverlay() and this function again.

If a non-optional parameter returned by the getDescription() is not filled with one of the parameter provided by the params or their type/dimension do not match, this function will report an error.

For instance, to register a point parameter interact:

# Let's create a group node
group = app.createNode("fr.inria.built-in.Group")

# Create a Double2D parameter that serve as a 2D point
param = group.createDouble2DParam("point","Point")
group.refreshUserParamsGUI()

# Create a point interact for the parameter
interact = PyPointOverlayInteract()

# The PyPointOverlayInteract descriptor requires at least a single Double2DParam
# that serve as a "position" role. Map it against the parameter we just created
# Note that we reference the "point" parameter by its script-name
interactParams = {"position": "point"}

# Register the overlay on the group, it will now be displayed on the viewer
group.registerOverlay(interact, interactParams)
NatronEngine.Effect.removeOverlay(overlay)
Parameters:overlayPyOverlayInteract

Remove an overlay previously registered with registerOverlay

FileParam

Inherits StringParamBase

Synopsis

This parameter is used to specify an input file (i.e: a file that already exist).

Functions
Member functions description
NatronEngine.FileParam.openFile()

When called in GUI mode, this will open a file dialog for the user. Does nothing in background mode.

NatronEngine.FileParam.reloadFile()

Force a refresh of the data read from the file. Any cached data associated to the file will be discarded.

NatronEngine.FileParam.setSequenceEnabled(enabled)
Parameters:enabledbool

This method is deprecated. Use setDialogType instead. Determines whether the file dialog opened by openFile() should have support for file sequences or not.

NatronEngine.FileParam.setDialogType(existingFiles, useSequences, fileTypes)
Parameters:
  • existingFilesbool
  • useSequencesbool
  • fileTypesSequence

Set the kind of file selector this parameter should be. If existingFiles is set to True then the dialog will only be able to select existing files, otherwise the user will be able to specify non-existing files. The later case is useful when asking the user for a location where to save a file.

If useSequences is True then the file dialog will be able to gather files by sequences. This is mostly useful when you need to retrieve images from the user.

fileTypes indicates a list of file types accepted by the dialog.

Group

Inherited by: Effect, App, GuiApp

Synopsis

Base class for Effect and App. See detailed description below.

Functions
Detailed Description

This is an abstract class, it is derived by 2 different classes:

  • App which represents an instance of Natron, or more specifically the current project.
  • Effect which represents a node in the node graph.

The getNode(fullyQualifiedName) can be used to retrieve a node in the project, although all nodes already have an auto-declared variable by Natron.

Member functions description
NatronEngine.Group.getChildren()
Return type:sequence

Returns a sequence with all nodes in the group. Note that this function is not recursive and you’d have to call getChildren() on all sub-groups to retrieve their children, etc…

NatronEngine.Group.getNode(fullyQualifiedName)
Parameters:fullySpecifiedNamestr
Return type:Effect

Retrieves a node in the group with its fully qualified name. The fully qualified name of a node is the script-name of the node prefixed by all the group hierarchy into which it is, e.g.:

Blur1 # the node is a top level node

Group1.Group2.Blur1 # the node is inside Group2 which is inside Group1

Basically you should never call this function because Natron already pre-declares a variable for each node upon its creation. If you were to create a new node named “Blur1” , you could the access it in the Script Editor the following way:

app1.Blur1
GroupParam

Inherits Param

Synopsis

A group param is a container for other parameters. See detailed description.

Functions
Detailed Description

A group param does not hold any relevant value. Rather this is a purely graphical element that is used to gather multiple parameters under a group. On the graphical interface a GroupParam looks like this:

_images/groupParam.png

When a Param is under a group, the getParent() will return the group as parent.

Member functions description
NatronEngine.GroupParam.addParam(param)
Parameters:paramParam

Adds param into the group.

Warning

Note that this function cannot be called on groups that are not user parameters (i.e: created either by script or by the “Manage user parameters” user interface)

Warning

Once called, you should call refreshUserParamsGUI() to update the user interface.

NatronEngine.GroupParam.getIsOpened()
Return type:bool

Returns whether the group is currently expanded (True) or folded (False).

NatronEngine.GroupParam.setAsTab()

Set this group as a tab. When set as a tab, it will be inserted into a special TabWidget of the Effect. For instance, on the following screenshot, to and from are 2 groups on which setAsTab() has been called.

_images/groupAsTab.png
NatronEngine.GroupParam.setOpened(opened)
Parameters:openedbool

Set this group to be expanded (opened = True) or folded (opened = False)

ImageLayer
Synopsis

A small object representing a layer of an image. For example, the base image layer is the color layer, or sometimes called “RGBA”. Some other default layers include ForwardMotion, BackwardMotion, DisparityLeft,DisparityRight, etc… .

See detailed description…

Detailed Description

A Layer is constituted of a layer name and a set of channel names (also called components). You can get a sequence with all the channels in the layer with the function getComponentsNames(). For some default layers, the components may be represented by a prettier name for the end-user, such as DisparityLeft instead of XY. When the ImageLayer does not have a pretty name, its pretty name will just be a concatenation of all channel names in order.

There is one special layer in Natron: the color layer. It be represented as 3 different types: RGBA, RGB or Alpha. If the ImageLayer is a color layer, the method isColorPlane() will return True

ItemsTable

Inherited by: Roto, Tracker

Synopsis

A class representing a table or tree in which each row is an instance of a ItemBase. For instance, the RotoPaint and Tracker nodes use this class to represent their view in the settings panel.

See detailed description below.

Functions
  • def getItemByFullyQualifiedScriptName (fullyQualifiedName)
  • def getTopLevelItems ()
  • def getSelectedItems ()
  • def :meth:`insertItem<NatronEngine.ItemsTable.insertItem>`(index,item,parent)
  • def :meth:`removeItem<NatronEngine.ItemsTable.removeItem>`(item)
  • def :meth:`getAttributeName<NatronEngine.ItemsTable.getAttributeName>`()
  • def :meth:`getTableName<NatronEngine.ItemsTable.getTableName>`()
  • def :meth:`isModelParentingEnabled<NatronEngine.ItemsTable.isModelParentingEnabled>`()
Detailed Description

The ItemsTable class is a generic class representing either a table or tree view such as the Tracker node tracks table or the RotoPaint node items tree.

Each item in the table represents a full row and is an instance of the ItemBase class.

In the model, items may be either top-level (no parent) or child of another item.

Some models may disable the ability to have parent items, in which case all items are considered top-level. This is the case for example of the Tracker class. You can find out if parenting is enabled by calling isModelParentingEnabled().

Items in the table are part of the attributes automatically defined by Natron as explained in this section.

The ItemsTable object itself is an attribute of the effect holding it. To find out the name of the Python attribute that represents the object you can call getAttributeName().

For instance, for the RotoPaint node, the model is defined under the roto attribute, so the function getAttributeName would return roto.

The model may also be accessed on the effect with the getItemsTable()
function.

Each item in the table has a script-name that is unique with respect to its siblings: A top-level item cannot have the same script-name as another top-level item but may have the same script-name as a child of a top-level item.

An item is always an attribute of its parent item (if it has one) or of the ItemsTable directly. For example on the RotoPaint node, if we have one top-level layer named Layer1 with an item named Bezier1 inside of this layer, in Python it would be accessible as such:

app.RotoPaint1.Layer1.Bezier1
Member functions description
NatronEngine.ItemsTable.getItemByFullyQualifiedScriptName(fullyQualifiedScriptName)
Parameters:fullyQualifiedScriptNamestr
Return type:ItemBase

Given an item fully qualified script-name (relative to the ItemsTable itself), returns the corresponding item if it exists.

E.g:

If we have a table as such:

Layer1
    Layer2
        Bezier1

The fully qualified script-name of Bezier1 is *Layer1.Layer2.Bezier1*
NatronEngine.ItemsTable.getTopLevelItems()
Return type:Sequence

Return a list of items in the table that do not have a parent.

NatronEngine.ItemsTable.getSelectedItems()
Return type:Sequence

Return a list of selected items in the table.

NatronEngine.ItemsTable.insertItem(index, item, parent)
Parameters:
  • indexint
  • item – :class:`ItemBase<NatronEngine.ItemBase>
  • parent – :class:`ItemBase<NatronEngine.ItemBase>

Inserts the given item in the table. If the model supports parenting and parent is not None, the item will be added as a child of parent. If there is a parent, index is the index at which to insert the item in the children list. If there is no parent, index is the index at which to insert the item in the table top-level items list. If index is out of range, the item will be added to the end of the list.

NatronEngine.ItemsTable.removeItem(item)
Parameters:item – :class:`ItemBase<NatronEngine.ItemBase>

Removes the given item from the model.

NatronEngine.ItemsTable.getAttributeName()
Return type:str

Returns the name of the Python attribute automatically declared by Natron under which table items are automatically defined. For example, for the RotoPaint node,

items are declared under the roto attribute.
NatronEngine.ItemsTable.getTableName()
Return type:str

Returns the name of the table: this is used to identify uniquely the kind of objects a table may handle. Since a node may have multiple tables, each table must have a different name.

NatronEngine.ItemsTable.isModelParentingEnabled()
Return type:bool

Returns whether items may have a parent or not in this table.

NatronEngine.Natron.PixmapEnum

See here for potential values of this enumeration.

PageParam

Inherits Param

Synopsis

A page param is a container for other parameters. See detailed description.

Functions
Detailed Description

A page param does not hold any relevant value. Rather this is a purely graphical element that is used to gather parameters under a tab. On the graphical interface a PageParam looks like this (e.g. the Controls tab of the panel)

_images/pageParam.png

Warning

All parameters MUST be in a container, being a group or a page. If a Param is not added into any container, Natron will add it by default to the User page.

NatronEngine.PageParam.addParam(param)
param param:Param

Adds param into the page.

Warning

Note that this function cannot be called on pages that are not user parameters (i.e: created either by script or by the “Manage user parameters” user interface)

Warning

Once called, you should call refreshUserParamsGUI() to update the user interface.

Param

Inherited by: ParametricParam, PageParam, GroupParam, ButtonParam, AnimatedParam, StringParamBase, PathParam, OutputFileParam, FileParam, StringParam, BooleanParam, ChoiceParam, ColorParam, DoubleParam, Double2DParam, Double3DParam, IntParam, Int2DParam, Int3DParam

Synopsis

This is the base class for all parameters. Parameters are the controls found in the settings panel of a node. See details here.

Functions
Detailed Description

The Param object can be used to control a specific parameter of a node. There are different types of parameters, ranging from the single checkbox (boolean) to parametric curves. Each type of parameter has specific functions to control the parameter according to its internal value type. In this base class, all common functionalities for parameters have been gathered.

Warning

Note that since each child class has a different value type, all the functions to set/get values, and set/get keyframes are specific for each class.

Note that most of the functions in the API of Params take a dimension parameter. This is a 0-based index of the dimension on which to operate. For instance the dimension 0 of a RGB color parameter is the red value.

Various properties controls the parameter regarding its animation or its layout or other things. Some properties are listed here, but the list is not complete. Refer to the reference on each parameter type for all accessible properties.

  • addNewLine: When True, the next parameter declared will be on the same line as this parameter
  • canAnimate: This is a static property that you cannot control which tells whether animation can be enabled for a specific type of parameter
  • animationEnabled: For all parameters that have canAnimate=True, this property controls whether this parameter should be able to animate (= have keyframes) or not
  • evaluateOnChange: This property controls whether a new render should be issued when the value of this parameter changes
  • help: This is the tooltip visible when hovering the parameter with the mouse
  • enabled: Should this parameter be editable by the user or not. Generally, disabled parameters have their text drawn in black.
  • visible: Should this parameter be visible in the user interface or not
  • persistent: If true then the parameter value will be saved in the project otherwise it will be forgotten between 2 runs

Note that most of the properties are not dynamic and only work for user created parameters. If calling any setter/getter associated to these properties, nothing will change right away. A call to refreshUserParamsGUI() is needed to refresh the GUI for these parameters.

For non user-parameters (i.e: parameters that were defined by the underlying OpenFX plug-in), only their dynamic properties can be changed since refreshUserParamsGUI() will only refresh user parameters.

The following dynamic properties can be set on all parameters (non user and user):

Name: Type: Dynamic: Setter: Getter: Default:
visible bool yes setVisible getIsVisible True
enabled bool yes setEnabled getIsEnabled True

Note

animates is set to True by default only if it is one of the following parameters:

IntParam Int2DParam Int3DParam DoubleParam Double2DParam Double3DParam ColorParam

Note that ParametricParam , GroupParam, PageParam, ButtonParam, FileParam, OutputFileParam, PathParam cannot animate at all.

Parameter in-viewer interface

In Natron, each Effect may have an interface in the Viewer, like the Roto or Tracker nodes have.

You may add parameters on the viewer UI for any Effect as well as edit it. This also apply to the Viewer node UI as well, so one can completely customize the Viewer toolbars. The user

guide covers in detail how to customize the Viewer UI for an Effect.

To add a parameter to the Viewer UI of an Effect, use the function insertParamInViewerUI(parameter, index). You may then control its layout, using the setViewerUILayoutType(type) function and the spacing between parameters in pixels with setViewerUIItemSpacing(spacingPx). You may set the text label or icon of the parameter specifically in the viewer UI by calling setViewerUIIconFilePath(filePath,checked) and setViewerUILabel(label).

Member functions description
NatronEngine.Param.beginChanges()

This can be called before making heavy changes to a parameter, such as setting thousands of keyframes. This call prevent the parameter from doing the following: - Trigger a new render when changed - Call the paramChanged callback when changed - Adjusting the folded/expanded state automatically for multi-dimensional parameters.

Make sure to call the corresponding endChanges() function when done

NatronEngine.Param.copy(other[, dimension=-1])
Parameters:
  • otherParam
  • dimensionint
Return type:

bool

Copies the other parameter values, animation and expressions at the given dimension. If dimension is -1, all dimensions in min(getNumDimensions(), other.getNumDimensions()) will be copied.

Note

Note that types must be convertible:

IntParam,DoubleParam, ChoiceParam, ColorParam and BooleanParam can convert between types but StringParam cannot.

Warning

When copying a parameter, only values are copied, not properties, hence if copying a choice parameter, make sure that the value you copy has a meaning to the receiver otherwise you might end-up with an undefined behaviour, e.g.:

If ChoiceParam1 has 3 entries and the current index is 2 and ChoiceParam2 has 15 entries and current index is 10, copying ChoiceParam2 to ChoiceParam1 will end-up in undefined behaviour.

This function returns True upon success and False otherwise.

NatronEngine.Param.curve(time[, dimension=-1, view="Main"])
Parameters:
  • timefloat
  • dimensionint
  • viewstr
Return type:

float

If this parameter has an animation curve on the given dimension, then the value of that curve at the given time is returned. If the parameter has an expression on top of the animation curve, the expression will be ignored, ie.g: the value of the animation curve will still be returned. This is useful to write custom expressions for motion design such as looping, reversing, etc…

NatronEngine.Param.endChanges()

To be called when finished making heavy changes to a parameter, such as setting thousands of keyframes.

A call to endChanges should always match a corresponding previous call to beginChanges() Note that they can be nested.

NatronEngine.Param.getAddNewLine()
Return type:bool

Returns whether the parameter is on a new line or not.

NatronEngine.Param.getCanAnimate()
Return type:bool

Returns whether this class can have any animation or not. This cannot be changed. calling setAnimationEnabled(True) will not enable animation for parameters that cannot animate.

NatronEngine.Param.getEvaluateOnChange()

NatronEngine.Param.getHelp()
Return type:str

Returns the help tooltip visible when hovering the parameter with the mouse on the GUI;

NatronEngine.Param.getIsAnimationEnabled()

Returns the number of dimensions. For exampel a Double3DParam has 3 dimensions. A ParametricParam has as many dimensions as there are curves.

NatronEngine.Param.getParent()
Return type:NatronEngine.Param

If this param is within a group, then the parent will be the group. Otherwise the param’s parent will be the:doc:page<PageParam> onto which the param appears in the settings panel.

NatronEngine.Param.getParentEffect()
Return type:NatronEngine.Effect

If the holder of this parameter is an effect, this is the effect. If the holder of this parameter is a table item, this will return the effect holding the item itself.

NatronEngine.Param.getParentItemBase()
rtype:

NatronEngine.ItemBase

If the holder of this parameter is a table item, this is the table item.

getApp()
Return type:NatronEngine.App

If the holder of this parameter is the app itself (so it is a project setting), this is the app object.

Parameters:
  • minfloat
  • maxfloat
Return type:

float

Returns a pseudo-random value in the interval [min, max[. The value is produced such that for a given parameter it will always be the same for a given time on the timeline, so that the value can be reproduced exactly.

Note

Note that if you are calling multiple times random() in the same parameter expression, each call would return a different value, but they would all return the same value again if the expressions is interpreted at the same time, e.g.:

# Would always return the same value at a given timeline’s time. random() - random()

Note that you can ensure that random() returns a given value by calling the overloaded function random(min,max,time,seed) instead.

NatronEngine.Param.random(min, max, time[, seed=0])
Parameters:
  • minfloat
  • maxfloat
  • timefloat
  • seedunsigned int
Return type:

float

# ret == 0 always
NatronEngine.Param.randomInt(min, max)
Parameters:
  • minint
  • maxint
Return type:

int

Same as random(min,max) but returns an integer in the range [min,*max*[

NatronEngine.Param.randomInt(min, max, time[, seed=0])
Parameters:
  • minint
  • maxint
  • timefloat
  • seedunsigned int
Return type:

Parameters:persistentbool

Set whether this parameter should be persistent or not. Non persistent parameter will not be saved in the project. See getIsPersistent

NatronEngine.Param.setVisible(visible)
Parameters:visiblebool

Set whether this parameter should be visible or not to the user. See getIsVisible()

NatronEngine.Param.setViewerUILayoutType(type)
Parameters:typeNatronEngine.Natron.ViewerContextLayoutTypeEnum

Set the layout type of this parameter if it is present in the viewer interface of the Effect holding it.

NatronEngine.Param.setViewerUIItemSpacing(spacing)
Parameters:spacingint

Set the item spacing after this parameter if it is present in the viewer interface of the Effect holding it.

NatronEngine.Param.setViewerUIIconFilePath(filePath[, checked=False])
Parameters:
  • filePathstr
  • checkedbool

Set the icon file path of this parameter if it is present in the viewer interface of the Effect holding it. For buttons, if checked it false, the icon will be used when the button is unchecked, if checked it will be used when the button is checked. This function only has an effect on user created parameters.

NatronEngine.Param.setViewerUILabel(label)
Parameters:labelstr

Set the label of this parameter if it is present in the viewer interface of the Effect holding it. This function only has an effect on user created parameters.

NatronEngine.Param.setViewerUIVisible(visible)
Parameters:visiblebool

Set this parameter visible or not in the Viewer UI. Only valid for parameters for which the function getHasViewerUI() returns True.

NatronEngine.Param.setExpressionCacheEnabled(enabled)
Parameters:enabledbool

Set whether caching of expression results is enabled. By default this is True. This can be turned off if an expression is set on a parameter but the expression depends on external data (other than parameter values, such as a file on disk). These external data would be unknown from Natron hence the expression cache would never invalidate.

NatronEngine.Param.linkTo(otherParam[, thisDimension=-1, otherDimension=-1, thisView="All", otherView="All"])
Parameters:
  • otherParamParam
  • thisDimensionint
  • otherDimensionint
  • thisViewstr
  • otherViewstr
Return type:

bool

This parameter will share the value of otherParam. They need to be both of the same type but may vary in dimension, as long as thisDimension is valid according to the number of dimensions of this parameter and otherDimension is valid according to the number of dimensions of otherParam. If thisDimension is -1 then it is expected that otherDimension is also -1 indicating that all dimensions should respectively be slaved.

If this parameter has split views, then only view(s) specified by thisView will be slaved to the otherView of the other parameter. If thisView is “All” then it is expected that otherView is also “All” indicating that all views should be respectively slaved. If not set to “All” then the view parameters should name valid views in the project settings.

This parameter thisDimension will be controlled entirely by the otherDimension of otherParam until a call to unlink(thisDimension) is made

Parameters:
  • dimensionint
  • viewstr

If the given dimension of this parameter was previously linked, then this function will remove the link and the value will no longer be shared with any other parameters. If dimension equals -1 then all dimensions will be unlinked. If view is set to “All” then all views will be unlinked, otherwise it should name valid views in the project settings.

Note

The animation and values that were present before the link will remain.

ParametricParam

Inherits Param

Synopsis

A parametric param represents one or more parametric functions as curves. See detailed explanation below.

Functions
Detailed Description
_images/parametricParam.png

A parametric parameter has as many dimensions as there are curves. Currently the number of curves is static and you may only specify the number of curves via the nbCurves argument of the createParametricParam(name,label,nbCurves) function.

Parametric curves work almost the same way that animation curves do: you can add control points and remove them.

You can peak the value of the curve at a special parametric position with the getValue(dimension,parametricPosition) function. The parametric position is represented by the X axis on the graphical user interface.

Functions
Detailed Description

By default the user can select a single directory as path, unless setAsMultiPathTable() is called in which case a table is presented to the user to specify multiple directories like this:

_images/multiPathParam.png

When using multiple paths, internally they are separated by a ; and the following characters are escaped as per the XML specification:

  • < becomes &lt;
  • > becomes &gt;
  • & becomes &amp;
  • becomes &quot;
  • becomes &apos;

Some more characters are escaped, you can see the full function in the source code of Natron here

PyCoreApplication

Inherited by: PyGuiApplication

Synopsis

This object represents a background instance of Natron. See detailed description

Functions
Detailed Description

When running Natron there’s a unique instance of the PyCoreApplication object. It holds general information about the process.

Generally, throughout your scripts, you can access this object with the variable natron that Natron pre-declared for you, e.g.:

natron.getPluginIDs()

Warning

The variable natron belongs to the module NatronEngine, hence make sure to make the following import:

from NatronEngine import*

Otherwise with a regular import you can still access natron by prepending the module:

NatronEngine.natron

Warning

The variable stored in the module NatronEngine contains a reference to a PyCoreApplication. If you need to have the GUI functionalities provided by PyGuiApplication, you must then use the variable natron belonging to the module NatronGui. Hence make sure to make the following import to have access to natron:

from NatronGui import*

With a regular import you can access it using NatronGui.natron.

Warning

Make sure to not make the 2 following imports, otherwise the natron variable will not point to something expected:

#This you should not do!
from NatronEngine import *
from NatronGui import *

#This is OK
import NatronEngine
import NatronGui

#This can also be done for convenience
from NatronEngine import NatronEngine.natron as NE
from NatronGui import NatronGui.natron as NG

This class is used only for background (command-line) runs of Natron, that is when you launch Natron in the following ways:

Natron -b ...
Natron -t
NatronRenderer

For interactive runs of Natron (with the user interface displayed), the derived class PyGuiApplication is used instead, which gives access to more GUI specific functionalities.

You should never need to make a new instance of this object yourself. Note that even if you did, internally the same object will be used and they will all refer to the same Natron application.

In GUI mode, a :doc`PyGuiApplication` can have several projects opened. For each project you can refer to them with pre-declared variables app1 , app2, etc…

In background mode, there would be only 1 project opened, so Natron does the following assignment for you before calling any scripts:

app = app1

See App to access different opened projects.

Member functions description
class NatronEngine.PyCoreApplication

Defines a new variable pointing to the same underlying application that the natron variable points to. This is equivalent to calling:

myVar = natron

Return type:App

Returns the App instance corresponding to the last project the user interacted with.

NatronEngine.PyCoreApplication.getNatronDevelopmentStatus()
Return type:str

NatronEngine.settings.afterProjectCreated.set(pythonFunctionName)

Note

Clever use of this function can be made in the init.py script to do generic stuff for all projects (whether they are new projects or loaded projects). For instance one might want to add a list of Formats to the project. See the example here

NatronEngine.PyCoreApplication.setOnProjectLoadedCallback(pythonFunctionName)
Param:str

Convenience function to set the Default After Project Loaded callback. Note that this will override any callback set in the Preferences–>Python–>Default After Project Loaded. This is exactly the same as calling:

NatronEngine.settings.defOnProjectLoaded.set(pythonFunctionName)
PyOverlayInteract
Synopsis

An overlay interact is an object used to draw and interact with on the viewer of Natron. An overlay interact object is associated to an effect. Usually an overlay interact is associated to a set of Parameters for which this object provides an easier interaction. For instance, the Transform node has an overlay interact to help the user control the transformation directly in the viewer.

See detailed description below.

Functions
Detailed Description

This class allows to directly provide a custom overlay interact for any existing node. To do so you need to inherit this class and provide an implementation for all the event handlers that you need. The minimum to implement would be the draw() function to provide the drawing.

The drawing itself is handled with OpenGL. You need to import the PyOpenGL package. Read the documentation of each function to better understand the context in which each event handler is called on its parameters.

To actually use an interact with an effect you need to call the registerOverlay(overlay, params) function on an Effect.

The interact will most likely interact with parameters of the node, these will be fetched in the fetchParameters(params) function. Note that this function may throw an error if a required parameter does not exist on the effect. In case of such failure, the interact will not be added to the node.

To determine the kind of parameters needed by an interact in order to work (e.g: a Point interact requires at least a Double2DParam to represent the position), the getDescription() function must be implemented. This function returns a dictionary of role names mapped against a description for a parameter. Then the fetchParameters(params) function takes a dictionary of role names mapped against actual parameter script-names that exist on the effect we are calling registerOverlay(overlay, params) on. This description scheme allows to restrain the usage of an overlay to ensure it has a defined behaviour.

Pixel scale vs. Render scale:

Most event handlers take a renderScale parameter. The render scale should be multiplied to the value of any spatial parameter, e.g: the position of a 2D point parameter.

The getPixelScale() function returns an additional scale that maps the coordinates of the viewport to the coordinates of the OpenGL orthographic projection.

To convert a point in OpenGL ortho coordinates to viewport coordinates you divide by the pixel scale, and to convert from viewport coordinates to OpenGL ortho you would multiply by the pixel scale.

Member functions description
NatronEngine.PyOverlayInteract.PyOverlayInteract()

Make a new overlay interact instance. This interact will only become valid when adding it to an Effect with the registerOverlay(overlay, params)

function.

NatronEngine.PyOverlayInteract.describeParameters()
Return type:PyDict

Returns a dictionary describing all parameters requirement for this interact in order to function properly. The key of each item is a string indicating the role name of a parameter. The same key is used in the fetchParameters(params) function. The value of each item is a tuple describing a parameter. The tuple contains 3 elements:

  • A string indicating the type of the parameter that must be provided.

This string corresponds to the value returned by the getTypeName() function of the Param class.

  • An integer indicating the number of dimensions of the paremeter, (e.g: 2 for a Double2DParam)
  • A boolean indicating whether this parameter is optional or not. When optional the parameter

does not have to be provided in order for the overlay to function properly

PyOverlayInteract.isColorPickerValid()
Return type:bool

Returns whether the color returned by getColorPicker() is valid or not. When invalid you may not assume that the value corresponds to what is currently picked by the cursor in the viewer.

Returns the effect currently holding this interact. This function may return None if the interact was not yet registered (or removed from) on an effect.

NatronEngine.PyOverlayInteract.getColorPicker()
Return type:ColorTuple

Returns the color of the pixel under the mouse on the viewer. Note that this is only valid if the function isColorPickerValid() returns True.

Return type:Double2DTuple

Returns the pixel scale of the current orthographic projection. See this section for more informations

NatronEngine.PyOverlayInteract.getViewportSize()
Return type:Int2DTuple

Returns the viewport width and height in pixel coordinates.

NatronEngine.PyOverlayInteract.getSuggestedColor()
Return type:PyTuple

Returns a tuple with the color suggested by the user in the settings panel of the node to draw the overlay. This may be ignored but should be preferred to using a hard coded color. The first element of the tuple is a boolean indicating whether the suggested color is valid or not. If invalid, you should not attempt to use it. The 4 next elements are the RGBA values in [0., 1.] range of the suggested color.

NatronEngine.PyOverlayInteract.setColorPickerEnabled(enabled)
Parameters:enabledbool

Enable color picking: whenever the user hovers the mouse on the viewer, this interact will be able to retrieve the color under the mouse with the getColorPicker() function.

This must correspond exactly to a value returned by the function getTypeName() of a sub-class of Param. nDims is the number of dimensions expected on the parameter (e.g: 2 for a Double2DParam) optional indicates whether this parameter is expected to be optional or not. If optional, this function will not fail if the parameter cannot be found.

This function returns the parameter matching the given role and name if it could be found.

NatronEngine.PyOverlayInteract.fetchParameters(params)
Parameters:paramsPyDict
Return type:bool

Inherits ItemBase

Synopsis

A small item sub-class that handles strokes painted by the user

See detailed description…

Functions
Detailed Description

A stroke is internally a list of 2D points with a timestamp and a pressure for each sample. Each sample is of type StrokePoint.

You can get a list of all samples with the func:getPoints()<NatronEngine.StrokeItem.getPoints> function. You can set the entire stroke points at once with the func:setPoints(strokes)<NatronEngine.StrokeItem.setPoints> function.

A stroke item consists of multiple disconnected sub-strokes. For example if the user starts drawing, releases the pen and then draws again without changing settings, it is likely the same item will be re-used instead of creating a new one.

Track

Inherits: ItemBase

Synopsis

This class represents one track marker as visible in the tracker node or on the viewer.

See detailed description below.

Functions
Detailed Description

The track is internally represented by multiple parameters which holds animation curve for various data, such as: the track center, the pattern 4 corners, the error score, the search-window, etc… Each of them can be retrieved with the getParam(scriptName) function.

Here is a small example showing how to retrieve the tracking data for a track:

myTrack = app.Tracker1.tracker.track1

keyframes = []

# get the number of keys for the X dimension only and try match the Y keyframes
nKeys = myTrack.centerPoint.getNumKeys(0)
for k in range(0,nKeys):

    # getKeyTime returns a tuple with a boolean value indicating if it succeeded and
    # the keyframe time

    gotXKeyTuple = myTrack.centerPoint.getKeyTime(k, 0)
    frame = gotXKeyTuple[1]

    # Only consider keyframes which have an X and Y value
    # If Y does not have a keyframe at this frame, ignore the keyframe
    # getKeyIndex returns a value >=0 if there is a keyframe
    yKeyIndex = myTrack.centerPoint.getKeyIndex(frame, 1)

    if yKeyIndex == -1:
        continue

    # Note that even if the x curve or y curve didn't have a keyframe we
    # could still call getValueAtTime but the value would be interpolated by
    # Natron with surrounding keyframes, which is not what we want.

    x = myTrack.centerPoint.getValueAtTime(frame, 0)
    y = myTrack.centerPoint.getValueAtTime(frame, 1)

    keyframes.append((x,y))

print keyframes

After calling this function you should call refreshUserParamsGUI() to refresh the user interface. The refreshing is done in a separate function because it may be expensive and thus allows you to make multiple changes to user parameters at once while keeping the user interface responsive.

NatronEngine.UserParamHolder.refreshUserParamsGUI()

This function must be called after new user parameter were created or removed. This will re-create the user interface for the parameters and can be expensive.

NatronGui

Detailed Description

Here are listed all classes being part of NatronEngine module. This module is loaded by Natron natively in GUI mode only. In that case, access is granted to these classes in your scripts without importing anything. Scripts that want to operate both in command line background mode and in GUI mode should poll the isBackground() function on the natron object before calling functions dependent on the module NatronGui. E.g:

if not NatronEngine.natron.isBackground():
    # do GUI only stuff here
GuiApp

Inherits App

Synopsis

This class is used for GUI application instances. See detailed description…

Functions
Detailed Description

See App for the documentation of base functionalities of this class.

To create a new modal dialog , use the createModalDialog() function.

Several functions are made available to pop dialogs to ask the user for filename(s) or colors. See getFilenameDialog(filters,location) and getRGBColorDialog().

To create a new custom python panel, there are several ways to do it:

  • Sub-class the PyPanel class and make your own PySide widget
  • Create a PyPanel object and add controls using user parameters (as done for modal dialogs)

Once created, you can register the panel in the project so that it gets saved into the layout by calling registerPythonPanel(panel,pythonFunction)

Member functions description
NatronGui.GuiApp.createModalDialog()
Return type:PyModalDialog

Creates a modal dialog : the control will not be returned to the user until the dialog is not closed. Once the dialog is created, you can enrich it with parameters or even raw PySide Qt widgets. To show the dialog call the function exec() on the dialog.

NatronGui.GuiApp.getFilenameDialog(filters[, location=None])
Parameters:
  • filterssequence
  • locationstr
Return type:

str

Opens-up a file dialog to ask the user for a single filename which already exists.

filters is a list of file extensions that should be displayed in the file dialog.

location is the initial location the dialog should display, unless it is empty in which case the dialog will display the last location that was opened previously by a dialog.

NatronGui.GuiApp.getSequenceDialog(filters[, location=None])
Parameters:
  • filterssequence
  • locationstr
Return type:

str

Same as getFilenameDialog(filters,location) but the dialog will accept sequence of files.

NatronGui.GuiApp.getDirectoryDialog([location=None])
Parameters:locationstr
Return type:str

Same as getFilenameDialog(filters,location) but the dialog will only accept directories as a result.

NatronGui.GuiApp.saveFilenameDialog(filters[, location=None])
Parameters:
  • filterssequence
  • locationstr
Return type:

str

Opens-up a file dialog to ask the user for a single filename. If the file already exists, the user will be warned about potential overriding of the file.

filters is a list of file extensions that should be displayed in the file dialog.

location is the initial location the dialog should display, unless it is empty in which case the dialog will display the last location that was opened previously by a dialog.

NatronGui.GuiApp.saveSequenceDialog(filters[, location=None])
Parameters:
  • filterssequence
  • locationstr
Return type:

str

Same as saveFilenameDialog(filters,location) but the dialog will accept sequence of files.

Opens-up a color dialog to ask the user for an RGB color.

NatronGui.GuiApp.getTabWidget(scriptName)
Parameters:scriptNamestr
Return type:PyTabWidget

Returns the tab-widget with the given scriptName. The scriptName of a tab-widget can be found in the user interface when hovering with the mouse the “Manage layout” button (in the top left-hand corner of the pane)

_images/paneScriptName.png
NatronGui.GuiApp.moveTab(tabScriptName, pane)
Parameters:
  • tabScriptNamestr
  • panePyTabWidget
Return type:

bool

Attempts to move the tab with the given tabScriptName into the given pane and make it current in the pane. This function returns True upon success or False otherwise.

Warning

Moving tabs that are not registered to the application via registerPythonPanel(panel,pythonFunction) will not work.

NatronGui.GuiApp.registerPythonPanel(panel, pythonFunction)
Parameters:
  • panelPyPanel
  • scriptNamestr

Registers the given panel into the project. When registered, the panel will be saved into the layout for the current project and a new entry in the “Panes” sub-menu of the “Manage layouts” button (in the top left-hand corner of each tab widget) will appear for this panel. pythonFunction is the name of a python-defined function that takes no argument that should be used to re-create the panel.

NatronGui.GuiApp.unregisterPythonPanel(panel)
Parameters:panelPyPanel

Unregisters a previously registered panel.

NatronGui.GuiApp.getSelectedNodes([group = None])
Return type:sequence

Returns a sequence of nodes currently selected in the given group. You can pass the app object to get the top-level NodeGraph. If passing None, the last user-selected NodeGraph will be used:

topLevelSelection = app.getSelectedNodes()

group = app.createNode("fr.inria.built-in.Group")

groupSelection = app.getSelectedNodes(group)
NatronGui.GuiApp.getViewer(scriptName)
Parameters:scriptNamestr

Returns the viewer with the given scriptName if one can be found.

NatronGui.GuiApp.getUserPanel(scriptName)
Parameters:scriptNamestr

Returns a user panel matching the given scriptName if there is any.

NatronGui.GuiApp.selectNode(node, clearPreviousSelection)
Parameters:
  • nodeEffect
  • clearPreviousSelectionbool

NatronGui.GuiApp.deselectNode(node)
Parameters:nodeEffect

Deselect the given node in its containing nodegraph. If the node is not selected, this function does nothing.

NatronGui.GuiApp.setSelection(nodes)
Parameters:nodessequence

Set all the given nodes selected in the nodegraph containing them and wipe any current selection.

Note

All nodes must be part of the same nodegraph (group), otherwise this function will fail.

NatronGui.GuiApp.selectAllNodes([group=None])
Parameters:groupGroup

Select all nodes in the given group. You can pass the app object to get the top-level NodeGraph. If passing None, the last user-selected NodeGraph will be used.

NatronGui.GuiApp.clearSelection([group=None])

Wipe any current selection in the given group. You can pass the app object to get the top-level NodeGraph. If passing None, the last user-selected NodeGraph will be used.

NatronGui.GuiApp.renderBlocking(effect, firstFrame, lastFrame, frameStep)
Parameters:
  • effectEffect
  • firstFrameint
  • lastFrameint
  • frameStepint

Starts rendering the given effect on the frame-range defined by [firstFrame,*lastFrame*]. The frameStep parameter indicates how many frames the timeline should step after rendering each frame. The value must be greater or equal to 1. The frameStep parameter is optional and if not given will default to the value of the Frame Increment parameter in the Write node.

For instance:

render(effect,1,10,2)

Would render the frames 1,3,5,7,9

This is a blocking function. A blocking render means that this function returns only when the render finishes (from failure or success).

This function should only be used to render with a Write node or DiskCache node.

NatronGui.GuiApp.renderBlocking(tasks)
Parameters:taskssequence

This function takes a sequence of tuples of the form (effect,firstFrame,lastFrame[,frameStep]) The frameStep is optional in the tuple and if not set will default to the value of the Frame Increment parameter in the Write node.

This is an overloaded function. Same as render(effect,firstFrame,lastFrame,frameStep) but all tasks will be rendered concurrently.

This function is called when rendering a script in background mode with multiple writers.

This is a blocking call.

PyGuiApplication

Inherits PyCoreApplication

Synopsis

See PyCoreApplication for a detailed explanation of the purpose of this object. This class is only used when Natron is run in GUI mode (with user interface). It gives you access to more GUI functionalities via the GuiApp class.

Functions
Member functions description
class NatronGui.PyGuiApplication

See PyCoreApplication()

NatronGui.PyGuiApplication.addMenuCommand(grouping, function)
Parameters:
  • groupingstr
  • functionstr

Adds a new menu entry in the menubar of Natron. This should be used exclusively in the initGui.py initialisation script.

The grouping is a string indicating a specific menu entry where each submenu is separated from its parent menu with a /:

File/Do something special

MyStudio/Scripts/Our special trick

The function is the name of a python defined function.

Warning

If called anywhere but from the initGui.py script, this function will fail to dynamically add a new menu entry.

Example:

def printLala():
    print("Lala")

natron.addMenuCommand("Inria/Scripts/Print lala script","printLala")

This registers in the menu Inria–>Scripts an entry named Print lala script which will print Lala to the Script Editor when triggered.

NatronGui.PyGuiApplication.addMenuCommand(grouping, function, key, modifiers)
Parameters:
  • groupingstr
  • functionstr
  • keyPySide.QtCore.Qt.Key
  • modifiersPySide.QtCore.Qt.KeyboardModifiers

Same as addMenuCommand(grouping,function) excepts that it accepts a default shortcut for the action. See PySide documentation for possible keys and modifiers.

The user will always be able to modify the shortcut from the built-in shortcut editor of Natron anyway.

NatronGui.PyGuiApplication.getGuiInstance(idx)
Parameters:idxint
Return type:GuiApp

Same as getInstance(idx) but returns instead an instance of a GUI project.

Basically you should never call this function as Natron pre-declares all opened projects with the following variables: app1 for the first opened project, app2 for the second, and so on…

NatronGui.PyGuiApplication.informationDialog(title, message)
Parameters:
  • titlestr
  • messagestr

Shows a modal information dialog to the user with the given window title and containing the given message.

NatronGui.PyGuiApplication.warningDialog(title, message)
Parameters:
  • titlestr
  • messagestr

Shows a modal warning dialog to the user with the given window title and containing the given message.

NatronGui.PyGuiApplication.errorDialog(title, message)
Parameters:
  • titlestr
  • messagestr

Shows a modal error dialog to the user with the given window title and containing the given message.

NatronGui.PyGuiApplication.questionDialog(title, message)
Parameters:
  • titlestr
  • messagestr
Return type:

NatronEngine.StandardButtonEnum

Shows a modal question dialog to the user with the given window title and containing the given message. The dialog will be a “Yes” “No” dialog, and you can compare the result to the NatronEngine.StandardButtonEnum members.

PyModalDialog

Inherits QDialog UserParamHolder

Synopsis

A modal dialog to ask information to the user or to warn about something. See detailed description…

Functions
Detailed Description

The modal dialog is a way to ask the user for data or to inform him/her about something going on. A modal window means that control will not be returned to the user (i.e. no event will be processed) until the user closed the dialog.

If you are looking for a simple way to just ask a question or report an error, warning or even just a miscenalleous information, use the informationDialog(title,message) function.

To create a new PyModalDialog, just use the createModalDialog() function, e.g.:

# In the Script Editor

dialog = app1.createModalDialog()

To show the dialog to the user, use the exec_() function inherited from QDialog

dialog.exec_()

Note that once exec_() is called, no instruction will be executed until the user closed the dialog.

The modal dialog always has OK and Cancel buttons. To query which button the user pressed, inspect the return value of the exec_() call:

if dialog.exec_():
    #The user pressed OK
    ...
else:
    #The user pressed Cancel or Escape
Adding user parameters:

You can start adding user parameters using all the createXParam functions inherited from the NatronEngine.UserParamHolder class.

Once all your parameters are created, create the GUI for them using the refreshUserParamsGUI() function:

myInteger = dialog.createIntParam("myInt","This is an integer very important")
myInteger.setAnimationEnabled(False)
myInteger.setAddNewLine(False)

#Create a boolean on the same line
myBoolean = dialog.createBooleanParam("myBool","Yet another important boolean")

dialog.refreshUserParamsGUI()

dialog.exec_()

You can then retrieve the value of a parameter once the dialog is finished using the getParam(scriptName) function:

if dialog.exec_():
    intValue = dialog.getParam("myInt").get()
    boolValue = dialog.getParam("myBool").get()

Warning

Unlike the Effect class, parameters on modal dialogs are not automatically declared by Natron, which means you cannot do stuff like dialog.intValue

Member functions description
NatronGui.PyModalDialog.addWidget(widget)
Parameters:widgetQWidget

Append a QWidget inherited widget at the bottom of the dialog. This allows to add custom GUI created directly using PySide that will be inserted after any custom parameter.

NatronGui.PyModalDialog.getParam(scriptName)
Parameters:scriptNamestr
Return type:Param

Returns the user parameter with the given scriptName if it exists or None otherwise.

NatronGui.PyModalDialog.insertWidget(index, widget)
Parameters:
  • indexint
  • widgetPySide.QtGui.QWidget

Inserts a QWidget inherited widget at the given index of the layout in the dialog. This allows to add custom GUI created directly using PySide. The widget will always be inserted after any user parameter.

NatronGui.PyModalDialog.setParamChangedCallback(callback)
Parameters:callbackstr

Registers the given Python callback to be called whenever a user parameter changed. The parameter callback is a string that should contain the name of a Python function.

The signature of the callback used on PyModalDialog is:

callback(paramName, app, userEdited)
  • paramName indicating the script-name of the parameter which just had its value changed.
  • app : This variable will be set so it points to the correct application instance.
  • userEdited : This indicates whether or not the parameter change is due to user interaction (i.e: because the user changed the value by theirself) or due to another parameter changing the value of the parameter via a derivative of the setValue(value) function.

Example:

def myParamChangedCallback(paramName, app, userEdited):
    if paramName == "myInt":
        intValue = thisParam.get()
        if intValue > 0:
            myBoolean.setVisible(False)

dialog.setParamChangedCallback("myParamChangedCallback")
PyPanel

Inherits :QWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html> UserParamHolder

Synopsis

A custom PySide pane that can be docked into PyTabWidget. See detailed description…

Functions
Detailed Description

The PyPanel class can be used to implement custom PySide widgets that can then be inserted as tabs into tab-widgets .

There are 2 possible usage of this class:

Sub-classing:

When sub-classing the PyPanel class, you should specify when calling the base class constructor that you do not want to use user parameters, as this might conflict with the layout that you will use:

class MyPanel(NatronGui.PyPanel):
    def __init__(scriptName,label,app):
        NatronGui.PyPanel.__init__(scriptName,label,False,app)
        ...

You’re then free to use all features proposed by PySide in your class, including signal/slots See the following example.

Using the PyPanel API:

You can start adding user parameters using all the createXParam functions inherited from the UserParamHolder class.

Once all your parameters are created, create the GUI for them using the refreshUserParamsGUI() function:

panel = NatronGui.PyPanel("fr.inria.mypanel","My Panel",True,app)
myInteger = panel.createIntParam("myInt","This is an integer very important")
myInteger.setAnimationEnabled(False)
myInteger.setAddNewLine(False)

#Create a boolean on the same line
myBoolean = panel.createBooleanParam("myBool","Yet another important boolean")

panel.refreshUserParamsGUI()

You can then retrieve the value of a parameter at any time using the getParam(scriptName) function:

intValue = panel.getParam("myInt").get()
boolValue = panel.getParam("myBool").get()

Warning

Unlike the Effect class, parameters on panels are not automatically declared by Natron, which means you cannot do stuff like panel.intValue

You can get notified when a parameter’s value changed, by setting a callback using the setParamChangedCallback(callback) function that takes the name of a Python-defined function in parameters. The variable thisParam will be declared prior to calling the callback, referencing the parameter which just had its value changed.

Managing the panel:

Once created, you must add your panel to a PyTabWidget so it can be visible. Use the getTabWidget(scriptName) function to get a particular pane and then use the appendTab(tab) function to add this panel to the pane.

Warning

Note that the lifetime of the widget will be by default the same as the project’s GUI because PyPanel is auto-declared by Natron.

panel = NatronGui.PyPanel("fr.inria.mypanel","My Panel",True,app)
...
...
pane = app.getTabWidget("pane1")
pane.appendTab(panel)
app.mypanel = panel

If you want the panel to persist in the project so that it gets recreated and placed at its original position when the user loads the project, you must use the registerPythonPanel(panel,function) function.

Note that the function parameter is the name of a Python-defined function that takes no parameter used to create the widget, e.g.:

def createMyPanel():
panel = NatronGui.PyPanel(“MyPanel”,True,app) … #Make it live after the scope of the function app.mypanel = panel

app.registerPythonPanel(app.mypanel,”createMyPanel”)

This function will also add a custom menu entry to the “Manage layout” button (located in the top-left hand corner of every pane) which the user can trigger to move the custom pane on the selected pane.

_images/customPaneEntry.png
Saving and restoring state:

When the panel is registered in the project using the registerPythonPanel(panel,function) function, you may want to also save the state of your widgets and/or special values.

To do so, you must sub-class PyPanel and implement the save() and restore(data) functions.

Note

User parameters, if used, will be automatically saved and restored, you don’t have to save it yourself. Hence if the panel is only composed of user parameters that you want to save, you do not need to sub-class PyPanel as it will be done automatically for you.

The function save() should return a string containing the serialization of your custom data.

The function restore(data) will be called upon loading of a project containing an instance of your panel. You should then restore the state of the panel from your custom serialized data.

Note that the auto-save of Natron occurs in a separate thread and for this reason it cannot call directly your save() function because it might create a race condition if the user is actively modifying the user interface using the main-thread.

To overcome this, Natron has an hidden thread-safe way to recover the data you have serialized using the save() function. The downside is that you have to call the onUserDataChanged() function whenever a value that you want to be persistent has changed (unless this is a user parameter in which case you do not need to call it).

Warning

If you do not call onUserDataChanged(), the save() function will never be called, and the data never serialized.

Member functions description
NatronGui.PyPanel.PyPanel(label, useUserParameters, app)
Parameters:
  • labelstr
  • useUserParametersbool
  • appGuiApp

Make a new PyPanel with the given label that will be used to display in the tab header. If useUserParameters is True then user parameters support will be activated, attempting to modify the underlying layout in these circumstances will result in undefined behaviour.

NatronGui.PyPanel.addWidget(widget)
Parameters:widgetQWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html>

Append a QWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html> inherited widget at the bottom of the dialog. This allows to add custom GUI created directly using PySide that will be inserted after any custom parameter.

Warning

This function should be used exclusively when the widget was created using useUserParameters = True

NatronGui.PyPanel.getParam(scriptName)
Parameters:scriptNamestr
Return type:Param

Returns the user parameter with the given scriptName if it exists or None otherwise.

Warning

This function should be used exclusively when the widget was created using useUserParameters = True

NatronGui.PyPanel.getParams()
Return type:sequence

Returns all the user parameters used by the panel.

Warning

This function should be used exclusively when the widget was created using useUserParameters = True

NatronGui.PyPanel.insertWidget(index, widget)
Parameters:
  • indexint
  • widgetQWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html>

Inserts a QWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html> inherited widget at the given index of the layout in the dialog. This allows to add custom GUI created directly using PySide. The widget will always be inserted after any user parameter.

Warning

This function should be used exclusively when the widget was created using useUserParameters = True

NatronGui.PyPanel.setParamChangedCallback(callback)
Parameters:callbackstr

Registers the given Python callback to be called whenever a user parameter changed. The parameter callback is a string that should contain the name of a Python function.

The signature of the callback used on PyModalDialog is:

callback(paramName, app, userEdited)
  • paramName indicating the script-name of the parameter which just had its value changed.
  • app : This variable will be set so it points to the correct application instance.
  • userEdited : This indicates whether or not the parameter change is due to user interaction (i.e: because the user changed the value by theirself) or due to another parameter changing the value of the parameter via a derivative of the setValue(value) function.

Example:

def myParamChangedCallback(paramName, app, userEdited):
    if paramName == "myInt":
        intValue = thisParam.get()
        if intValue > 0:
            myBoolean.setVisible(False)

panel.setParamChangedCallback("myParamChangedCallback")

Warning

This function should be used exclusively when the widget was created using useUserParameters = True

NatronGui.PyPanel.setPanelLabel(label)
Parameters:callbackstr

Set the label of the panel as it will be displayed on the tab header of the PyTabWidget. This name should be unique.

NatronGui.PyPanel.getPanelLabel()
Return type:str

Get the label of the panel as displayed on the tab header of the PyTabWidget.

NatronGui.PyPanel.getPanelScriptName()
Return type:str

Get the script-name of the panel as used internally. This is a unique string identifying the tab in Natron.

NatronGui.PyPanel.onUserDataChanged()

Callback to be called whenever a parameter/value (that is not a user parameter) that you want to be saved has changed.

Warning

If you do not call onUserDataChanged(), the save()NatronGui.PyPanel.save() function will never be called, and the data never serialized.

Warning

This function should be used exclusively when the widget was created using useUserParameters = True

NatronGui.PyPanel.save()
Return type:str

Warning

You should overload this function in a derived class. The base version does nothing.

Note

User parameters, if used, will be automatically saved and restored, you don’t have to save it yourself. Hence if the panel is only composed of user parameters that you want to save, you do not need to sub-class PyPanel as it will be done automatically for you.

Returns a string with the serialization of your custom data you need to be persistent.

NatronGui.PyPanel.restore(data)
Parameters:datastr

Warning

You should overload this function in a derived class. The base version does nothing.

This function should restore the state of your custom PyPanel using the custom data that you serialized. The data are exactly the return value that was returned from the save() function.

PyTabWidget
Synopsis

A PyTabWidget is one of the GUI pane onto which the user can dock tabs such as the NodeGraph, CurveEditor… See detailed description…

Functions
Detailed Description

The PyTabWidget class is used to represent panes visible in the user interface:

_images/tabwidgets.png

On the screenshot above, each PyTabWidget is surrounded by a red box.

You cannot construct tab widgets on your own, you must call one of the splitVertically() or splitHorizontally() functions to make a new one based on another existing ones.

By default the GUI of Natron cannot have less than 1 tab widget active, hence you can always split it to make new panes.

To retrieve an existing PyTabWidget you can call the getTabWidget(scriptName) function of GuiApp.

pane1 = app.getTabWidget(“Pane1”)

Note that the script-name of a pane can be seen on the graphical user interface by hovering the mouse over the “Manage layout” button (in the top left hand corner of a pane).

_images/paneScriptName.png
Managing tabs

To insert tabs in the TabWidget you can call either appendTab(tab) or insertTab(index,tab).

Warning

Note that to insert a tab, it must be first removed from the tab into which it was.

To remove a tab, use the function removeTab(tab) on the parent PyTabWidget

For convenience to move tabs around, there is a moveTab(tab,pane) function in GuiApp.

The function closeTab(index) can be used to close permanently a tab, effectively destroying it.

To change the current tab, you can use one of the following functions:

  • setCurrentIndex(index)<NatronGui.PyTabWidget.setCurrentIndex>
  • setNextTabCurrent()<NatronGui.PyTabWidget.setNextTabCurrent>

To float the current tab into a new floating window, use the floatCurrentTab()<NatronGui.PyTabWidget.floatCurrentTab> function.

Managing the pane

To close the pane permanently, use the closePane()<NatronGui.PyTabWidget.closePane> function. To float the pane into a new floating window with all its tabs, use the floatPane() function.

Member functions description
NatronGui.PyTabWidget.appendTab(tab)
Parameters:tabQWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html>

Appends a new tab to the tab widget and makes it current.

NatronGui.PyTabWidget.closeCurrentTab()

Closes the current tab, effectively destroying it.

NatronGui.PyTabWidget.closeTab(index)

Closes the tab at the given index, effectively destroying it.

NatronGui.PyTabWidget.closePane()

Closes this pane, effectively destroying it. Note that all tabs will not be destroyed but instead moved to another existing pane.

Warning

If this pane is the last one on the GUI, this function does nothing.

NatronGui.PyTabWidget.count()
Return type:int

Returns the number of tabs in this pane.

NatronGui.PyTabWidget.currentWidget()
Return type:QWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html>

Make a new floating window with a single pane and moves the current tab of this pane to the new pane of the floating window.

NatronGui.PyTabWidget.floatPane()

Make a new floating window and moves this pane to the new window (including all tabs).

NatronGui.PyTabWidget.getCurrentIndex()
Return type:int

Returns the index of the current tab. This is 0-based (starting from the left).

NatronGui.PyTabWidget.getScriptName()
Return type:str

Returns the script-name of the pane, as used by the getTabWidget(scriptName) function.

NatronGui.PyTabWidget.getTabLabel(index)

NatronGui.PyTabWidget.removeTab(tab)
Parameters:tabQWidget <https://pyside.github.io/docs/pyside/PySide/QtGui/QWidget.html>

Removes the given tab from this pane if it is found. Note that this function does not destroy the tab, unlike closeTab(index).

This is used internally by moveTab(tab,pane).

NatronGui.PyTabWidget.removeTab(index)
Parameters:indexint

Same as removeTab(tab) but the index of a tab is given instead.

NatronGui.PyTabWidget.setCurrentIndex(index)
Parameters:indexint

Makes the tab at the given index (0-based) the current one (if the index is valid).

NatronGui.PyTabWidget.setNextTabCurrent()

Set the tab at getCurrentIndex() + 1 the current one. This functions cycles back to the first tab once the last tab is reached.

NatronGui.PyTabWidget.splitHorizontally()
Return type:PyTabWidget

Splits this pane into 2 horizontally-separated panes. The new pane will be returned.

NatronGui.PyTabWidget.splitVertically()
Return type:PyTabWidget

Splits this pane into 2 vertically-separated panes. The new pane will be returned.

Introduction

This section covers the basic principles for scripting in Python in Natron.

Natron plug-in paths

When looking for startup scripts or Python group plug-ins, Natron will look into the following search paths in order:

  • The bundled plug-ins path. There are 2 kinds of plug-ins: PyPlugs and OpenFX plug-ins. The bundled OpenFX plug-ins are located in Plugins/OFX/Natron in your Natron installation and the bundled PyPlugs in the directory Plugins/PyPlugs.

  • The standard user location for non OpenFX plug-ins (i.e. PyPlugs): that is the directory .Natron in the home directory, e.g.:

    On Windows that would be:

    C:\Documents and Settings\<username>\NatronUserData
    

    On OS X & Linux that would be:

    /home/<username>/NatronUserData
    

    Warning

    Note that the old ~/.Natron directory is no longer looked up by Natron.

  • The standard system location for non OpenFX plug-ins (i.e. PyPlugs):

    Windows:

    C:\Program Files\Common Files\Natron\Plugins
    

    OS X:

    /Library/Application Support/Natron/Plugins
    

    Linux:

    /usr/share/Natron/Plugins
    
  • All the paths indicated by the NATRON_PLUGIN_PATH environment variable. This environment variable should contain a separator between each path. On Windows the separator is the character ;, on Linux/macOS the separator is the character : , such as:

    # Windows: C:MyDataNatronPlugins;C:Users<username>DocumentsNatronPlugins

    # On Linux: /home/<username>/NatronPluginsA:/home/<username>/NatronPluginsB

    # On macOS: /Users/<username>/NatronPluginsA:/Users/<username>/NatronPluginsB

  • The user extra search paths in the Plug-ins tab of the Preferences of Natron.

If the setting “Prefer bundled plug-ins over system-wide plug-ins” is checked in the preferences then Natron will first look into the bundled plug-ins before checking the standard location. Otherwise, Natron will check bundled plug-ins as the last location.

Note that if the “User bundled plug-ins” setting in the preferences is unchecked, Natron will not attempt to load any bundled plug-ins.

Python Auto-declared variables

A lot of Python variables are pre-declared by Natron upon the creation of specific objects. This applies currently to the following objects:

The idea is that it is simpler to access a simple variable like this:

node = app1.Blur1

rather than call a bunch of functions such as:

node = app1.getNode("app1.Blur1")

To achieve this, auto-declared objects must be named with a correct syntax in a python script. For instance, the following variable would not work in Python:

>>> my variable = 2
File "<stdin>", line 1
my variable = 2
          ^
SyntaxError: invalid syntax

But the following would work:

>>> myVariable = 2

To overcome this issue, all auto-declared variables in Natron have 2 names:

1. A script-name: The name that will be used to auto-declare the variable to Python. This name cannot be changed and is set once by Natron the first time the object is created. This name contains only alpha-numeric characters and does not start with a digit.

2. A label: The label is what is displayed on the graphical user interface. For example the node label is visible in the node graph. This label can contain any character without any restriction.

Basically there can only ever be one instance of an object with a script-name (so it is identified uniquely) but several instances of this object could have the same label.

Generally when calling a function which takes an object name in parameter, you pass it always the script-name of the object. See for example getParam(name).

Knowing the script-name of a node:

The script-name of a node is visible in the graphical-user interface in the tool-tip of the widget to edit the label of the node:

_images/nodeScriptName.png

For children nodes (like tracks) you can access their script-name from the table of the Tracker node:

_images/trackScriptName.png

In command-line mode or via the Script Editor, you can also get the script-name of the node with the getScriptName() function of the Effect class.

Knowing the script-name of a parameter:

In the settings panel of a node, the script-name of a parameter is visible in bold in the tooltip displayed when hovering a parameter with the mouse:

_images/paramScriptName.png

In command-line mode or via the Script Editor you can also get the script-name of the parameter with the getScriptName() function of the Param class.

Knowing the script-name of an item of a Roto node:

In the settings panel of a roto node, the script-name of an item is visible in the tooltip when hovering the mouse on the label of the item

_images/rotoScriptName.png

In command-line mode or via the Script Editor you can also get the script-name of an item with the getScriptName() function of the ItemBase class.

Knowing the script-name of a track in a Tracker node:

In the settings panel of a tracker node, the script-name of an item is visible in the tooltip when hovering the mouse on the label column.

_images/trackerScriptName.png

In command-line mode or via the Script Editor you can also get the script-name of an item with the getScriptName() function of the ItemBase class.

Knowing the script-name of a tab-widget:

The script-name of a pane can be seen on the graphical user interface by hovering the mouse over the “Manage layout” button (in the top left hand corner of a pane).

_images/paneScriptName1.png
Knowing the script-name of a viewer:

The script-name of a viewer is the script-name of the node associated to it, e.g.:

app1.pane1.Viewer1
Knowing the script-name of a PyPanel:

The script-name of a PyPanel can be retrieved with the getPanelScriptName() function of the class.

Start-up scripts

On start-up Natron will run different start-up scripts to let you setup anything like callbacks, menus, etc…

There are 2 different initialization scripts that Natron will look for in the search paths.

  • init.py

    This script is always run and should only initialize non-GUI stuff. You may not use it to initialize e.g. new menus or windows. Generally this is a good place to initialize all the callbacks that you may want to use in your projects.

  • initGui.py

    This script is only run in GUI mode (that is with the user interface). It should initialize all gui-specific stuff like new menus or windows.

All the scripts with the above name found in the search paths will be run in the order of the search paths.

Warning

This is important that the 2 scripts above are named init.py and initGui.py otherwise they will not be loaded.

Warning

These scripts are run well before any application instance (i.e: project) is created. You should therefore not run any function directly that might rely on the app variable (or app1, etc…). However you’re free to define classes and functions that may rely on these variable being declared, but that will be called only later on, when a project will actually be created.

Examples

Natron in command-line

Natron has 3 different execution modes:

  • The execution of Natron projects (.ntp)
  • The execution of Python scripts that contain commands for Natron
  • An interpreter mode where commands can be given directly to the Python interpreter
General options:
[–background] or [-b] enables background mode rendering.
No graphical interface will be shown. When using NatronRenderer or the -t option this argument is implicit and you don’t need to use it. If using Natron and this option is not specified then it will load the project as if opened from the file menu.

[–interpreter] or [-t] [optional] <python script file path> enables Python interpreter mode. Python commands can be given to the interpreter and executed on the fly. An optional Python script filename can be specified to source a script before the interpreter is made accessible. Note that Natron will not start rendering any Write node of the sourced script, you must explicitly start it. NatronRenderer and Natron will do the same thing in this mode, only the init.py script will be loaded.

[–clear-cache] will clear the image cache on startup

[–clear-plugins-cache] will clear the plug-ins load cache on start-up, forcing them to reaload

Options for the execution of Natron projects:
Natron <project file path>

``–writer`` or ``-w`` <Writer node script name> [optional] <filename> [optional] <frameRange> specifies a Write node to render. When in background mode, the renderer will only try to render with the node script name following this argument. If no such node exists in the project file, the process will abort. Note that if you don’t pass the –writer argument, it will try to start rendering with all the writers in the project.

After the writer node script name you can pass an optional output filename and pass an optional frame range in the format firstFrame-lastFrame (e.g. 10-40).

Warning

You may only specify absolute file paths with the -i option, things like:

NatronRenderer -i MyReader ~/pictures.png -w MyWriter rendered###.exr

would not work. This would work on the other hand:

NatronRenderer -i MyReader /Users/me/Images/pictures.png -w MyWriter /Users/me/Images/rendered###.exr

Note that several ``-w`` options can be set to specify multiple Write nodes to render.

Warning

Note that if specified, then the frame range will be the same for all Write nodes that will render.

``–reader``* or **``-i`` <reader node script name> <filename> : Specify the input file/sequence/video to load for the given Reader node. If the specified reader node cannot be found, the process will abort.

Warning

You may only specify absolute file paths with the -i option, things like:

NatronRenderer -i MyReader ~/pictures.png -w MyWriter rendered###.exr

would not work. This would work on the other hand:

NatronRenderer -i MyReader /Users/me/Images/pictures.png -w MyWriter /Users/me/Images/rendered###.exr

``–onload`` or ``-l`` <python script file path> specifies a Python script to be executed after a project is created or loaded. Note that this will be executed in GUI mode or with NatronRenderer and it will be executed after any Python function set to the callback onProjectLoaded or onProjectCreated. The same rules apply to this script as the rules below on the execution of Python scripts.

``–render-stats`` or ``-s`` Enables render statistics that will be produced for each frame in form of a file located next to the image produced by the Writer node, with the same name and a -stats.txt extension. The breakdown contains information about each nodes, render times, etc. This option is useful for debugging purposes or to control that a render is working correctly. Please note that it does not work when writing video files.

Some examples of usage of the tool:

Natron /Users/Me/MyNatronProjects/MyProject.ntp

Natron -b -w MyWriter /Users/Me/MyNatronProjects/MyProject.ntp

NatronRenderer -w MyWriter /Users/Me/MyNatronProjects/MyProject.ntp

NatronRenderer -w MyWriter /FastDisk/Pictures/sequence###.exr 1-100 /Users/Me/MyNatronProjects/MyProject.ntp

NatronRenderer -w MyWriter -w MySecondWriter 1-10 /Users/Me/MyNatronProjects/MyProject.ntp

NatronRenderer -w MyWriter 1-10 -l /Users/Me/Scripts/onProjectLoaded.py /Users/Me/MyNatronProjects/MyProject.ntp

Example of a script passed to –onload:

import NatronEngine

#Create a writer when loading/creating a project
writer = app.createNode("fr.inria.openfx.WriteOIIO")
Options for the execution of Python scripts:
Natron <Python script path>

Note that the following does not apply if the -t option was given.

The script argument can either be the script of a Group that was exported from the graphical user interface or an exported project or even a script written by hand.

When executing a script, Natron first looks for a function with the following signature:

def createInstance(app,group):

If this function is found, the script will be imported as a module and it will be executed.

Warning

Note that when imported, the script will not have access to any external variable declared by Natron except the variable passed to the createInstance function.

If this function is not found the whole content of the script will be interpreted as though it were given to Python natively.

Note

In this case the script can have access to the external variables declared by Natron.

Either cases, the “app” variable will always be defined and pointing to the correct application instance. Note that if you are using Natron in GUI mode, it will source the script before creating the graphical user interface and will not start rendering. When in command-line mode (-b option or NatronRenderer) you must specify the nodes to render. If nothing is specified, all Write nodes that were created in the Python script will be rendered.

You can render specific Write nodes either with the -w option as described above or with the following option:

[–output] or [-o] <filename> <frameRange> specifies an Output node in the script that should be replaced with a Write node.

The option looks for a node named Output1 in the script and will replace it by a Write node much like when creating a Write node in the user interface.

A filename must be specified, it is the filename of the output files to render. Also a frame range must be specified if it was not specified earlier.

This option can also be used to render out multiple Output nodes, in which case it has to be used like this:

[–output1] or [-o1] looks for a node named Output1 [–output2] or [-o2] looks for a node named Output2

etc…

-c or [ –cmd ] “PythonCommand” : Execute custom Python code passed as a script prior to executing the Python script passed in parameter. This option may be used multiple times and each python command will be executed in the order they were given to the command-line.

Some examples of usage of the tool:

Natron /Users/Me/MyNatronScripts/MyScript.py

Natron -b -w MyWriter /Users/Me/MyNatronScripts/MyScript.py

NatronRenderer -w MyWriter /Users/Me/MyNatronScripts/MyScript.py

NatronRenderer -o /FastDisk/Pictures/sequence###.exr 1-100 /Users/Me/MyNatronScripts/MyScript.py

NatronRenderer -o1 /FastDisk/Pictures/sequence###.exr -o2 /FastDisk/Pictures/test###.exr 1-100 /Users/Me/MyNatronScripts/MyScript.py

NatronRenderer -w MyWriter -o /FastDisk/Pictures/sequence###.exr 1-100 /Users/Me/MyNatronScripts/MyScript.py

NatronRenderer -w MyWriter /FastDisk/Pictures/sequence.mov 1-100 /Users/Me/MyNatronScripts/MyScript.py -e "print \"Now executing MyScript.py...\""
Options for the execution of the interpreter mode:
Natron -t [optional] <Python script path>

Natron will first source the script passed in argument, if any and then return control to the user. In this mode, the user can freely input Python commands that will be interpreted by the Python interpreter shipped with Natron.

Some examples of usage of the tool:

Natron -t

NatronRenderer -t

NatronRenderer -t /Users/Me/MyNatronScripts/MyScript.py

Example

A typical example would be to convert an input image sequence to another format. There are multiple ways to do it from the command-line in Natron and we are going to show them all:

  • Passing a .ntp file to the command line and passing the correct arguments
  • Passing a Python script file to the command-line to setup the graph and render
With a Natron project (.ntp) file
With a Python script file

We would write a customized Python script that we pass to the command-line:

#This is the content of myStartupScript.py

reader = app.createReader("/Users/Toto/Sequences/Sequence__####.exr")
writer = app.createWriter("/Users/Toto/Sequences/Sequence.mov")

#The node will be accessible via app.MyWriter after this call
#We do this so that we can reference it from the command-line arguments
writer.setScriptName("MyWriter")

#The node will be accessible via app.MyReader after this call
reader.setScriptName("MyReader")


#Set the format type parameter of the Write node to Input Stream Format so that the video
#is written to the size of the input images and not to the size of the project
formatType =  writer.getParam("formatType")
formatType.setValue(0)

#Connect the Writer to the Reader
writer.connectInput(0,reader)

#When using Natron (Gui) then the render must explicitly be requested.
#Otherwise if using NatronRenderer or Natron -b the render will be automatically started
#using the command-line arguments

#To use with Natron (Gui) to start render
#app.render(writer, 10, 20)

To launch this script in the background, you can do it like this:

NatronRenderer /path/to/myStartupScript.py -w MyWriter 10-20

For now the output filename and the input sequence are static and would need to be changed by hand to execute this script on another sequence.

We can customize the Reader filename and Writer filename parameters using the command-line arguments:

NatronRenderer /path/to/myStartupScript.py -i MyReader /Users/Toto/Sequences/AnotherSequence__####.exr -w MyWriter /Users/Toto/Sequences/mySequence.mov 10-20

Let’s imagine that now we would need to also set the frame-rate of the video in output and we would need it to vary for each different sequence we are going to transcode. This is for the sake of this example, you could also need to modify other parameters in a real use-case.

Since the fps cannot be specified from the command-line arguments, we could do it in Python with:

MyWriter.getParam("fps").set(48)

And change the value in the Python script for each call to the command-line, but that would require manual intervention.

That’s where another option from the command-line comes into play: the ``-c`` option (or --cmd): It allows to pass custom Python code in form of a string that will be executed before the actual script.

To set the fps from the command-line we could do as such now:

NatronRenderer /path/to/myStartupScript.py -c "fpsValue=60" -w MyWriter 10-20

Which would require the following modifications to the Python script:

MyWriter.getParam("fps").set(fpsValue)

We could also set the same way the Reader and Writer file names:

NatronRenderer /path/to/myStartupScript.py -c "fpsValue=60; readFileName=\"/Users/Toto/Sequences/AnotherSequence__####.exr\"; writeFileName=\"/Users/Toto/Sequences/mySequence.mov\""

And modify the Python script to take into account the new readFileName and writeFileName parameters:

...
reader = app.createReader(readFileName)
writer = app.createNode(writeFileName)
...

The ``-c`` option can be given multiple times to the command-line and each command passed will be executed once, in the order they were given.

With a Natron project file:

Let’s suppose the user already setup the project via the GUI as such:

MyReader—>MyWriter

We can then launch the render from the command-line this way:

NatronRenderer /path/to/myProject.ntp -w MyWriter 10-20

We can customize the Reader filename and Writer filename parameters using the command-line arguments:

NatronRenderer  /path/to/myProject.ntp -i MyReader /Users/Toto/Sequences/AnotherSequence__####.exr -w MyWriter /Users/Toto/Sequences/mySequence.mov 10-20

Objects hierarchy Overview

When running Natron, several important objects are created automatically and interact at different levels of the application.

Natron is separated in 2 internal modules:

NatronEngine and NatronGui.

The latest is only available in GUI mode. You may access globally to the Natron process with either NatronEngine.natron or NatronGui.natron

NatronEngine.natron is of type PyCoreApplication and NatronGui.natron is of type PyGuiApplication. This is a singleton and there is only a single instance of that variable living throughout the execution of the Natron process.

When using with NatronGui.natron you get access to GUI functionalities in addition to the internal functionalities exposed by PyCoreApplication

Basically if using Natron in command-line you may only use NatronEngine.natron.

Note

You may want to use natron directly to avoid prefixing everything with NatronEngine. or NatronGui. by using a from NatronEngine import * statement. Be careful though as it then makes it more confusing for people reading the code as to which version of the natron variable you are using.

It handles all application-wide information about plug-ins, environment, application settings… but also can hold one or multiple application instance which are made available to the global variables via the following variables:

app1 # References the first instance of the application (the first opened project)
app2 # The second project
...

Note that in background command-line mode, there would always be a single opened project so Natron does the following assignment for you:

app = app1

Warning

Note that when running scripts in the Script Editor, the application is running in GUI mode hence the app variable is not declared.

The App object is responsible for managing all information relative to a project. This includes all the nodes, project settings and render controls. See this section to create and control nodes.

Each node can have parameters which are the controls found in the settings panel of the node.

The same Param class is also used for the project settings and the application settings (preferences).

Getting started

This section covers basic functionalities a Python script can do in Natron.

Creating and controlling nodes

Creating a new node:

To create a node in Natron, you would do so using the app instance via the function createNode(pluginId,majorVersion,group) like this:

app1.createNode("fr.inria.openfx.ReadOIIO")

In this line we specify that we want the first opened project to create a node instantiating the plug-in ReadOIIO. Note that if we were in background mode we could just write the following which would be equivalent:

app.createNode("fr.inria.openfx.ReadOIIO")

Since in command-line there is only a single project opened, Natron does the following assignment:

app = app1

If we were to create the node into a specific group, we would do so like this:

group = app.createNode("fr.inria.built-in.Group")

reader = app.createNode("fr.inria.openfx.ReadOIIO", -1, group)

Note that when passed the number -1, it specifies that we want to load the highest version of the plug-in found. This version parameter can be useful to load for example a specific version of a plug-in.

The pluginID passed to this function is a unique ID for each plug-in. If 2 plug-ins were to have the same ID, then Natron will create separate entries for each version.

You can query all plug-ins available in Natron this way:

allPlugins = natron.getPluginIDs()

You can also filter out plug-ins that contain only a given filter name:

# Returns only plugin IDs containing ".inria" in it

filteredPlugins = natron.getPluginIDs(".inria.")

In the user interface, the plug-in ID can be found when pressing the ? button located in the top right-hand corner of the settings panel:

_images/helpButton.png
_images/pluginID.png
Connecting a node to other nodes:

To connect a node to the input of another node you can use the connectInput(inputNumber,input) function.

The inputNumber is a 0-based index specifying the input on which the function should connect the given input Effect.

You can query the input name at a specific index with the following function:

print(node.getInputLabel(i))

Here is a small example where we would create 3 nodes and connect them together:

#Create a write node
writer = app.createNode("fr.inria.openfx.WriteOIIO")

#Create a blur
blur = app.createNode("net.sf.cimg.CImgBlur")

#Create a read node
reader = app.createNode("fr.inria.openfx.ReadOIIO")

#Connect the write node to the blur
writer.connectInput(0,blur)

#Connect the blur to the read node
blur.connectInput(0,reader)

Note that the following script would do the same since nodes are auto-declared variables

node = app.createNode("fr.inria.openfx.WriteOIIO")
print(node.getScriptName()) # prints WriteOIIO1

#The write node is now available via its script name app.WriteOIIO1

node = app.createNode("net.sf.cimg.CImgBlur")
print(node.getScriptName()) # prints CImgBlur1

#The blur node is now available via its script name app.BlurCImg1

node = app.createNode("fr.inria.openfx.ReadOIIO")
print(node.getScriptName()) # prints ReadOIIO1

#The ReadOIIO node is now available via its script name app.ReadOIIO1

app.WriteOIIO1.connectInput(0,app.BlurCImg1)
app.BlurCImg1.connectInput(0,app.ReadOIIO1)

Note that not all connections are possible, and sometimes it may fail for some reasons explained in the documentation of the connectInput(inputNumber,input) function.

You should then check for errors this way:

if not app.WriteOIIO1.connectInput(0,app.BlurCImg1):
    # Handle errors

You can check beforehand whether a subsequent connectInput call would succeed or not by calling the canConnectInput(inputNumber,input) which basically checks whether is is okay to do the connection or not. You can then safely write the following instructions:

if app.WriteOIIO1.canConnectInput(0,app.BlurCImg1):
    app.WriteOIIO1.connectInput(0,app.BlurCImg1)
else:
    # Handle errors

Note that internally connectInput calls canConnectInput to validate whether the connection is possible.

To disconnect an existing connection, you can use the disconnectInput(inputNumber) function.

Controlling parameters

Accessing a node’s parameters:

As for nodes, parameters are auto-declared objects. You can access an existing parameter of a node by its script-name:

app.BlurCImg1.size

Note that you can also access a parameter with the getParam(scriptName) function:

param = app.BlurCImg1.getParam("size")

but you should not ever need it because Natron pre-declared all variables for you.

The script-name of a parameter is visible in the user interface when hovering the parameter in the settings panel with the mouse. This is the name in bold:

_images/paramScriptName.png
Parameters type:

Each parameter has a type to represent internally different data-types, here is a list of all existing parameters:

Retrieving a parameter’s value:

Since each underlying type is different for parameters, each sub-class has its own version of the functions.

To get the value of the parameter at the timeline’s current time, call the get() or getValue() function.

If the parameter is animated and you want to retrieve its value at a specific time on the timeline, you would use the get(frame) or getValueAtTime(frame,dimension) function.

Note that when animated and the given frame time is not a time at which a keyframe exists, Natron will interpolate the value of the parameter between surrounding keyframes with the interpolation filter selected (by default it is smooth).

Modifying a parameter’s value:

You would set the parameter value by calling the set(value) or setValue(value) function. If the parameter is animated (= has 1 or more keyframe) then calling this function would create (or modify) a keyframe at the timeline’s current time.

To add a new keyframe the set(value,frame) or setValueAtTime(value,frame,dimension) function can be used.

To remove a keyframe you can use the deleteValueAtTime(frame,dimension) function. If you want to remove all the animation on the parameter at a given dimension, use the removeAnimation(dimension) function.

Warning

Note that the dimension is a 0-based index referring to the dimension on which to operate. For instance a Double2DParam has 2 dimensions x and y. To set a value on x you would use dimension = 0, to set a value on y you would use dimension = 1.

More information on parameter animation, multi-view and expressions can be found in the documentation of the AnimatedParam class.

Controlling other properties of parameters:

See the documentation for the Param class for a detailed explanation of other properties and how they affect the parameter.

Multi-view parameters

In a project setup to have multiple views (such as a stereo project), parameters may have different values and animation per view. Typically you may not want to apply the same strength of an effect on the left view and on the right view.

By default a parameter is not multi-view and all its views have the same value and animation curve.

You can split-off specific views by calling splitView(view) in which case the given view will be split from the other views and can be assigned different values.

By default the main view controlling all views that are not split yet is called Main. Any function that return a value will by default return the value for the Main view. Any function that change the state of the parameter will by default be applied on all views , even those that are split-off should receive the change. This is done with the keyword All.

Function that return values may not take the special All keyword and will error if an invalid parameter is supplied.

To unsplit a given view and re-group it under the Main view you can call the unSplitView(view) function.

Creating new parameters:

In Natron, the user has the possibility to add new parameters, called User parameters. They are pretty much the same than the parameters defined by the underlying OpenFX plug-in itself.

In the Python API, to create a new user parameter, you would need to call one of the createXParam(name,label,...) of the Effect class.

These parameters can have their default values and properties changed as explained in the documentation page of the Param class.

To remove a user created parameter you would need to call the removeParam(param) function of the Effect class.

Warning

Only user parameters can be removed. Removing parameters defined by the OpenFX plug-in will not work.

Parameters expressions

The value of a parameter can be set by Python expressions. An expression is a line of code that can either reference the value of other parameters or apply mathematical functions to the current value.

The expression will be executed every times the value of the parameter is fetched from a call to getValue(dimension) or get().

Warning

Note that when an expression is active, all animation is ignored and only the result of the expression will be used to return the value of the parameter.

When executing an expression, the expression itself has a scope. The scope of the expression defines all nodes and parameters that are possible to use in the expression in order to produce the output value.

Any node in the scope can has a variable declared corresponding to its script-name:

Blur1

You would then access a parameter of Blur1 also by its script-name:

Blur1.size

Group1.Blur1.size

Warning

Referencing the value of the same parameter which expression is being edited can lead to an infinite recursion which Python should warn you about

In fact this is exactly like referencing auto-declared nodes via the Script Editor except that the app prefix was removed for nodes in the scope.

See this section to learn how to determine the script-name of a node.

See this section to learn how to determine the script-name of a parameter.

By default a parameter’s expression can only refer to parameters of nodes belonging to the same Group, or to parameters belonging to the parent Group node.

Parameters of a Group node are also granted in the scope the parameters contained within that group.

For instance if your graph hierarchy looks like this:

Read1
Blur1
Group1/
    Input1
    Blur1
    Convolve1
    Roto1
    Output1
Viewer1

A parameter of Read1 would be able to reference any parameter of Read1, Blur1, Group1, Viewer1 but could not reference any parameter of the nodes within Group1.

Similarly, a parameter of Group1.Blur1 would be able to reference any parameter of Group1, Group1.Input1 , Group1.Blur1 , Group1.Convolve1 , Group1.Roto1 , Group1.Output1 but would not be able to reference any top-level node (Read1, Blur1, Viewer1) except the Group1 node.

A parameter of Group1 would on the other hand be able to reference any parameter in top-level nodes and in the nodes of Group1.

The scope was introduced to deal with problems where the user would write expressions referencing parameters that would probably no longer be referable when loading the script again in another project.

Warning

Note that you would still be able to reach any node or parameter in the project using the app1 (or app prefix in command-line mode) but is not recommended to do so:

app1.Blur1.size

All functions available in the Python API are made available to expressions. Also for convenience the math Python module has been made available by default to expressions.

Setting an expression:

To create an expression from the user interface, right click a parameter and choose Set Expression…

_images/setExprRightClick.png

Note that for multi-dimensional parameters such as ColorParam, the Set Expression… entry will only set an expression for the right-clicked dimension.

The Set Expression (all dimensions) entry will on the other hand set the same expression on all dimensions of the parameter at once.

_images/multiDimSetExprMenu.png

A dialog will open where you can write the expression:

_images/setExprDialog.png

By default you do not have to assign any variable as the result of the expression, Natron will do it by itself:

#Expression for Blur1.size

Transform1.translate.get[0]

#Will be expanded automatically by Natron to

ret = Transform1.translate.get[0]

However if you were to write an expression that spans over multiple lines you would need to specifically set the ret variable yourself and toggle-on the multi-line button:

a = acos(Transform1.translate.get[0])
b = sin(Transform1.rotate.get())
ret = (tan(a * b) / pi) + Group1.customParam.get()

You can also set an expression from a script using the setExpression(expr,hasRetVariable,dimension) function of AnimatedParam.

Writing an expression:

For convenience the following variables have been declared to Python when executing the expression:

  • thisNode: It references the node holding the parameter being edited
  • thisGroup: It references the group containing thisNode
  • thisParam: It references the param being edited
  • dimension: Defined only for multi-dimensional parameters, it indicates the dimension (0-based index) of the parameter on which the expression has effect.
  • frame: It references the current time on the timeline
  • The app variable will be set so it points to the correct application instance.

To reference the value of another parameter use the get() function which retrieves the value of the parameter at the current timeline’s time. If the parameter is multi-dimensional, you need to use the subscript operator to retrieve the value of a particular dimension.

The getValue(dimension) does the same thing but takes a dimension parameter to retrieve the value of the parameter at a specific dimension. The following is equivalent:

ColorCorrect1.MasterSaturation.get()[dimension]

ColorCorrect1.MasterSaturation.getValue(dimension)

Note that for 1-dimensional parameter, the get() function cannot be used with subscript, e.g.:

Blur1.size.get()

To retrieve the value of the parameter at a specific frame because the parameter is animated, you can use the get(frame) function.

Again the getValueAtTime(frame,dimension) does the same thing but takes a dimension parameter to retrieve the value of the parameter at a specific dimension. The following lines are equivalent to the 2 lines above:

ColorCorrect1.MasterSaturation.get(frame)[dimension]

ColorCorrect1.MasterSaturation.getValueAtTime(frame,dimension)

We ask for the value of the MasterSaturation parameter of the ColorCorrect1 node its value at the current frame and at the current dimension, which is the same as calling the get() function without a frame in parameter.

Copying another parameter through expressions:

If we want the value of the parameter size of the node BlurCImg1 to copy the parameter mix of the node DilateCImg1, we would set the following expression on the size parameter of the node BlurCImg1 (see setting an expression):

DilateCImg1.mix.get()

If mix has an animation and we wanted to get the value of the mix at the previous frame, the following code would work:

DilateCImg1.mix.get(frame - 1)

Note that when choosing the Link to… option when right-clicking a parameter, Natron writes automatically an expression to copy the parameter to link to for you.

Using random in expressions:

Sometimes it might be useful to add a random generator to produce noise on a value. However the noise produced must be reproducible such that when rendering multiple times the same frame or when loading the project again it would use the same value.

We had to add a specific random function in Natron that takes into account the state of a parameter and the current time on the timeline as a seed function to random.

Warning

We advise against using the functions provided by the module random.py of the Python standard library, as the values produced by these functions will not be reproducible between 2 runs of Natron for the same project.

The Natron specific random functions are exposed in the Param class.

When executing an expression, Natron pre-declares the random() function so that you do not have to do stuff like:

thisParam.random()

Instead you can just type the following in your expression:

myOtherNode.myOtherNodeParam.get() * random()

The random(min = 0.,max = 1.) function also takes 2 optional arguments indicating the range into which the return value should fall in. The range is defined by [min,max[.

#Returns a random floating point value in the range [1., 10.[ random(1.,10.)

For integers, use the randomInt(min,max) function instead:

#Returns a random integer in the range [1,100[
randomInt(1,100)

#Using the randomInt function with a given seed
seed = 5
randomInt(1,100,frame,seed)
Advanced expressions:

To write more advanced expressions based on fractal noise or perlin noise you may use the functions available in the ExprUtils class.

Expressions persistence

If you were to write a group plug-in and then want to have your expressions persist when your group will be instantiated, it is important to prefix the name of the nodes you reference in your expression by the thisGroup. prefix. Without it, Natron thinks you’re referencing a top-level node, i.e: a node which belongs to the main node-graph, however, since you’re using a group, all your nodes are no longer top-level and the expression will fail.

Examples
Setting the label of a Node so it displays the value of a parameter on the node-graph:

For instance, we may want to have on the shuffle node, the values of the output RGBA channels so we don’t have to open the settings panel to understand what the node is doing.

To do so, we set an expression on the “Label” parameter located in the “Node” tab of the settings panel.

_images/shuffleSubLabel.png
_images/shuffleLabelExpression.png

Set the following expression on the parameter

thisNode.outputR.getOption(thisNode.outputR.get()) + "\n" + thisNode.outputG.getOption(thisNode.outputG.get()) + "\n" + thisNode.outputB.getOption(thisNode.outputB.get()) + "\n" + thisNode.outputA.getOption(thisNode.outputA.get())
Generating custom animation for motion editing:

In this example we will demonstrate how to perform Loop,Negate and Reverse effects on an animation even though this is already available as a preset in Natron.

To do be able to do this we make use of the curve(frame,dimension) function of the Param class. This function returns the value of the animation curve (of the given dimension) at the given time.

If we were to write the following expression:

curve(frame)

The result would be exactly the animation curve of the parameter.

On the other hand if we write:

curve(-frame)
_images/CE_reverse.png

We have just reversed the curve, meaning that the actual result at the frame F will be in fact the value of the curve at the frame -F.

In the same way we can apply a negate effect:

-curve(frame)
_images/CE_negate.png

The loop effect is a bit more complicated and needs to have a frame-range in parameter:

firstFrame = 0
lastFrame = 10
curve(((frame - firstFrame) % (lastFrame - firstFrame + 1)) + firstFrame)
_images/CE_loop.png

Working with groups

Groups in Natron are a complete sub-nodegraph into which the user can manage nodes exactly like in the main nodegraph, but everything in that sub-group will be referenced as 1 node in the hierarchy above, e.g.:

_images/subGroups.png

A group can be created like any other node in Natron and by default embeds already 2 nodes: The Output node and one Input node.

The Output node is used to reference what would be the output of the internal graph of the group. In Natron, a node has necessarily a single output, hence if you add several Output nodes to a group, only the first Output node will be taken into account.

Note that you can also add Output nodes to the top-level graph of Natron (the main Node Graph). They are useful if you need to export your project as a group.

When used in the top-level graph, there can be multiple Output nodes, which can then be used when launching Natron from the command-line to render the script, e.g.:

NatronRenderer -o1 /FastDisk/Pictures/sequence###.exr -o2 /FastDisk/Pictures/test###.exr 1-100 /Users/Me/MyNatronScripts/MyScript.py

Where each argument o1, o2 expand respectively the nodes Output1 and Output2.

Warning

You should never attempt to change the script name of output nodes, otherwise Natron has no way to match the given command line arguments to the output nodes. In fact Natron will completely ignore your request if you explicitly try to set the script name of an Output node.

The Input node is not necessarily unique and represents 1 input arrow of the group node. You can also specify in the settings panel of the Input node whether this input should be considered as a mask or whether it should be optional.

Note

Note that the OpenFX standard specifies that Mask inputs must be optionals so when checking the mask parameter, this will automatically check the optional parameter.

You can freely rename an Input node, effectively changing the label attached to the arrow on the group node.

_images/inputLabels.png
Parameters expressions and groups

A common task is to add parameters to the group node itself which directly interact to nodes parameters used internally by this group.

You can add a new parameter to the group node by clicking the “Settings and presets” button and clicking “Manage user parameters…”:

_images/manageUserParams.png

A dialog will popup on which you can manage all the parameters that you added. By default a page is added automatically that will contain user parameters.

_images/addUserParams.png

To create a new parameter, click the add button, this brings up a new dialog:

_images/addNewParamDialog.png

In this dialog you can configure all the properties of the parameter exactly like you would do using the Python API.

Once created, the new parameter can be found in the “User” page of the settings panel:

_images/userPage.png

We can then set for instance an expression on the internal blur size parameter to copy the value of the blur size parameter we just added to the group node:

_images/blurExpression.png

The expression is now visible in a green-ish color on the parameter in the settings panel and the node on the node-graph has a green “E” indicator.

_images/settingsPanelExpression.png
_images/exprIndicator.png
Exporting a group

Once your group is setup correctly, you can export it as a Python script that Natron will generate automatically. We call them PyPlugs.

To do so, click the Export as Python plug-in button in the “Node” page of the settings panel of the Group node.

_images/exportButton.png

Exporting a group as a plug-in, means that it will create a Python script that will be able to re-create the group entirely and that will be loaded on startup like any other plug-in. That means that the group will also appear in the left toolbar of Natron and can potentially have an icon too.

_images/exportWindow.png

The Label is the name of the plug-in as it will appear in the user interface. It should not contain spaces or non Python friendly characters as it is going to be used as variable names in several places.

The Grouping is the tool-button under which the plug-in should appear. It accepts sub-menus notation like this: “Inria/StereoGroups”

The Icon relative path is the filepath to an image which should be used as icon for the plug-in. Note that it is a relative path to the location of the python script.

The directory is the location where the script should be written to. For the plug-in to be loaded by Natron, it should be in its search-paths hence if you select a directory that is not yet in the search-paths, it will prompt you to add it.

Note

A re-launch of Natron is required to re-scan the plug-ins and build the tool menus

Once restarted, the plug-in should now appear in the user interface

_images/toolbuttonGroup.png

and even in the tab menu of the node-graph:

_images/tabMenuGroup.png

Note

The plug-in ID of the group will be exactly the same as the Label you picked when exporting it, hence when creating a node using the group from a Python script, you would do so:

app.createNode(“MyBlurGroup”)

If several plug-ins have the same pluginID, Natron will then sort plug-ins by version.

The version of a plug-in by default when exporting it via Natron is 1.

Warning

If 2 plug-ins happen to have the same pluginID and version, Natron will then load the first one found in the search paths.

To change the pluginID and version of your group plug-in, you must implement the 2 following functions in the python script of the group:

# This function should return an int specifying the version of the plug-in
# If not implemented, Natron will use 1 by default
def getVersion():
    return VERSION

# This function should return a string specifying the ID of the plug-in, for example
# "fr.inria.groups.customBlur"
# If not implemented, Natron will use the label as a pluginID
def getPluginID():
    return UNIQUE_ID
Exporting a project as group

Similarly, Natron allows you to export the top-level node-graph as a Python group plug-in. From the “File” menu, select “Export project as group”.

Warning

To be exportable, your project should at least contain 1 output node.

Note

While this functionality is made for convenience, you should be cautious, as exporting a project containing Readers will probably not work very well in another project or computer because of file-paths no longer pointing to a valid location.

Warning

If you were to write a group plug-in and then want to have your expressions persist when your group will be instantiated, it is important to prefix the name of the nodes you reference in your expression by the thisGroup. prefix. Without it, Natron thinks you’re referencing a top-level node, i.e: a node which belongs to the main node-graph, however, since you’re using a group, all your nodes are no longer top-level and the expression will fail.

Moving nodes between groups

You can create a group from the selection in Natron by holding CTRL+SHIFT+G. This will effectively move all nodes selected into a new sub-group

You can also copy/cut/paste in-between groups and projects.

Creating a group by hand

You can also write a group plug-in by hand using the Python API of Natron.

Natron detects a Python file within the plug-in path as a PyPlug if it contains the following line [1]:

# Natron PyPlug

There may be Python files which are neither PyPlugs or Toolsets within these directories, for example python modules.

To work as a plug-in, your script should implemented the following functions:

# This function is mandatory and should return the label of the plug-in as
# visible on the user interface
def getLabel():
    return LABEL

# This function should return an int specifying the version of the plug-in
# If not implemented, Natron will use 1 by default
def getVersion():
    return VERSION

# This function should return a string specifying the ID of the plug-in, for example
# "fr.inria.groups.customBlur"
# If not implemented, Natron will use the label as a pluginID
def getPluginID():
    return UNIQUE_ID

# This function should return a string specifying the relative file path of an image
# file relative to the location of this Python script.
# This function is optional.
def getIconPath():
    return ICON_PATH

# This function is mandatory and should return the plug-in grouping, e.g.:
# "Other/Groups"
def getGrouping():
    return GROUPING

# This function is optional and should return a string describing the plug-in to the user.
# This is the text that will show up when the user press the "?" button on the settings panel.
def getDescription():
    return DESCRIPTION

# This function is mandatory and should re-create all the nodes and parameters state
# of the group.
# The group parameter is a group node that has been created by Natron and that  will host all
# the internal nodes created by this function.
# The app parameter is for convenience to have access in a generic way to the app object,
# no matter in which project instance your script is invoked in.
def createInstance(app, group):
    ...

The Python group plug-ins generated automatically by Natron are a good start to figure out how to write scripts yourself.

Warning

Python group plug-ins should avoid using any functionality provided by the NatronGui module because it would then break their compatibility when working in command-line background mode. The reason behind this is that the Python module NatronGui is not imported in command-line mode because internally it relies on the QtGui library, which may not be present on some render-farms. Attempts to load PyPlugs relaying on the NatronGui module would then fail and the rendering would abort.

Warning

Note that PyPlugs are imported by Natron which means that the script will not have access to any external variable declared by Natron except the variables passed to the createInstance function or the attributes of the modules imported.

Adding hand-written code (callbacks, etc…)

It is common to add hand-written code to a PyPlug. When making changes to the PyPlug from the GUI of Natron, exporting it again will overwrite any change made to the python script of the PyPlug. In order to help development, all hand-written code can be written in a separate script with the same name of the original Python script but ending with Ext.py, e.g.:

MyPyPlugExt.py

This extension script can contain for example the definition of all callbacks used in the PyPlug. When calling the createInstance(app,group) function, the PyPlug will call right at the end of the function the createInstanceExt(app,group) function. You can define it in your extension script if you want to apply extra steps to the creation of the group. For example you might want to actually set the callbacks on the group:

#This is in MyPyPlugExt.py

def paramChangedCallback(thisParam, thisNode, thisGroup, app, userEdited):
    print thisParam.getScriptName()

def createInstanceExt(app,group):
    # Note that the callback belongs to the PyPlug to so we use it as prefix
    group.onParamChanged.set("MyPyPlug.paramChangedCallback")

Note

Note that callbacks don’t have to be registered with the extension module prefix but just with the PyPlug’s name prefix since the “from … import *” statement is made to import the extensions script.

Starting Natron with a script in command line

Natron can be started with a Python script as argument.

When used in background mode (i.e: using NatronRenderer or Natron with the option -b) Natron will do the following steps:

  • Source the script
  • If found, run a function with the following signature createInstance(app,group)
  • Start rendering the specified writer nodes (with the -w option) and/or the Output nodes (with the -o option)

This allows to pass a group plug-in to Natron and render it easily if needed. Also, it can take arbitrary scripts which are not necessarily group plug-ins.

When Natron is launched in GUI mode but with a Python script in argument, it will do the following steps:

  • Source the script
  • If found, run a function with the following signature createInstance(app,group)
Toolsets

Toolsets in Natron are a predefined set of actions that will be applied to the node-graph. They work exactly like PyPlugs except that no actual group node will be created, only the content of the createInstance(app,group) function will be executed.

This useful to create pre-defined graphs, for example like the Split and Join plug-in in the Views menu.

To be recognized as a toolset, your PyPlug must implement the following function:

def getIsToolset():
    return True

Also the group parameter passed to the createInstance(app,group) function will be None because no group node is actually involved.

As with regular PyPlugs, the file must also contrain the line [1]:

# Natron PyPlug
[1](1, 2)

There was a bug in Natron versions 2.1.0 through 2.3.14 which prevented loading PyPlugs and Toolsets if they did not have a line that started with:

# This file was automatically generated by Natron PyPlug exporter

Using Callbacks

Callbacks are functions that are executed after or before a certain event in Natron. They are Python-defined methods that you declare yourself and then register to Natron in a different manner for each callback.

This document describes the signature that your different callbacks must have in order to work for each event. The parameters of your declaration must match exactly the same signature otherwise the function call will not work.

Warning

Note that callbacks will be called in background and GUI modes, hence you should wrap all GUI code by the following condition:

if not NatronEngine.natron.isBackground():
    #...do gui stuff
Callback persistence

If you want your callback to persist 2 runs of Natron; it is necessary that you define it in a script that is loaded by Natron, that is, either the init.py script (or initGui.py if you want it only available in GUI mode) or the script of a Python group plug-in (or its extension script, see here). See this section for more infos.

Here is the list of the different callbacks:

The param changed callback

This function is called every times the value of a parameter changes. This callback is available for all objects that can hold parameters,namely:

The signature of the callback used on the Effect is:

callback(thisParam, thisNode, thisGroup, app, userEdited)
  • thisParam : This is a Param pointing to the parameter which just had its value changed.
  • thisNode : This is a Effect pointing to the effect holding thisParam
  • thisGroup : This is a Effect pointing to the group holding thisNode or app otherwise if the node is in the main node-graph.
  • app : This variable will be set so it points to the correct application instance.
  • userEdited : This indicates whether or not the parameter change is due to user interaction (i.e: because the user changed the value by theirself) or due to another parameter changing the value of the parameter via a derivative of the setValue(value) function.

To get the node object containing this parameter, use the getParentEffect() function.

If this is a parameter of a table item (such as a Track in the tracker node or a Bezier in a Roto node), you may retrieve the item itself using the getParentItemBase() function. In this case the getParentEffect() function would return the effect containing the table item itself.

To retrieve the app instance into which the callback was called, you may call the getApp() function on the parameter.

For the parameter changed callback of PyPanel and PyModalDialog, the signature of the callback function is:

callback(paramName, app, userEdited)
  • paramName indicating the script-name of the parameter which just had its value changed.
  • app : This variable will be set so it points to the correct application instance.
  • userEdited : This indicates whether or not the parameter change is due to user interaction (i.e: because the user changed the value by theirself) or due to another parameter changing the value of the parameter via a derivative of the setValue(value) function.

Note

The difference between the callbacks on PyPanel and PyModalDialog and Effect is due to technical reasons: mainly because the parameters of the PyPanel class and PyModalDialog are not declared as attributes of the object.

Registering the param changed callback

To register the param changed callback of an Effect, you can do so in the settings panel of the node, in the “Node” tab, by entering the name of your Python function:

_images/settingsPanelParamChangedCB.png

You can also set the callback directly from the script: The callback is just another parameter of the node, on which you can call setValue(value) to set the name of the callback

def myBlurCallback(thisParam, thisNode, thisGroup, app, userEdited):
    ...

app.BlurCImg1.onParamChanged.set("myBlurCallback")

Note

If the callback is defined in a separate python file, such as the python script of a python group plug-in, then do not forget the module prefix, e.g.:

app.MyPlugin1.BlurCImg1.onParamChanged.set(“MyPlugin.myBlurCallback”)
Example
# This simple callback just prints a string when the "size" parameter of the BlurCImg
# node changes
def myBlurCallback(thisParam, thisNode, thisGroup, app, userEdited):
    if thisParam == thisNode.size:
        print("The size of the blur just changed!")

app.BlurCImg1.onParamChanged.set("myBlurCallback")
Using the param changed callback for PyModalDialog and PyPanel

To register the callback to the object, use the setParamChangedCallback(pythonFunctionName) function.

The following example is taken from the initGui.py script provided as example in this section.

Example
#Callback called when a parameter of the player changes
#The variable paramName is declared by Natron; indicating the name of the parameter which just had its value changed
def myPlayerParamChangedCallback(paramName, app, userEdited):

    viewer = app.getViewer("Viewer1")
    if viewer == None:
        return
    if paramName == "previous":
        viewer.seek(viewer.getCurrentFrame() - 1)
    elif paramName == "backward":
        viewer.startBackward()
    elif paramName == "forward":
        viewer.startForward()
    elif paramName == "next":
        viewer.seek(viewer.getCurrentFrame() + 1)
    elif paramName == "stop":
        viewer.pause()


def createMyPlayer():
    app.player = NatronGui.PyPanel("fr.inria.myplayer","My Player",True,app)
    #...
    app.player.setParamChangedCallback("myPlayerParamChangedCallback")
The After input changed callback

Similarly to the param changed callback, this function is called whenever an input connection of the node is changed. The signature is:

callback(inputIndex, thisNode, thisGroup, app)

Note

This function will be called even when loading a project

  • inputIndex : This is the input which just got connected/disconnected. You can fetch the input at the given index with the getInput(index) function of the Effect class.
  • thisNode : This is a Effect holding the input which just changed
  • thisGroup : This is a Effect pointing to the group holding thisNode. Note that it will be declared only if thisNode is part of a group.
  • app : points to the correct application instance.
Registering the input changed callback

To register the input changed callback of an Effect, you can do so in the settings panel of the node, in the “Node” tab, by entering the name of your Python function:

_images/inputChangedPanel.png

You can also set the callback directly from the script: The callback is just another parameter of the node, on which you can call setValue(value) to set the name of the callback

def inputChangedCallback(inputIndex, thisNode, thisGroup, app):
    ...

app.Merge1.onInputChanged.set("inputChangedCallback")
Example
# This simple callback just prints the input node name if connected or "None" otherwise
# node changes
def inputChangedCallback(inputIndex, thisNode, thisGroup, app):
    inp = thisNode.getInput(inputIndex)
    if not inp is None:
        print("Input ",inputIndex," is ",inp.getScriptName())
    else:
        print("Input ",inputIndex," is None")

app.Merge1.onInputChanged.set("inputChangedCallback")
The After project created callback

This function is called whenever a new project is created, that is either when launching Natron without loading a project, or when clicking “Create a new project” or “Close project”.

Note

Note that this function is never called when a project is loaded either via an auto-save or from user interaction.

The app variable will be set so it points to the correct application instance being created.

You can set the callback via the afterProjectCreated parameter of the settings of Natron.

_images/preferencesCallback.png

This is a good place to create custom panels and/or setup the node-graph with node presets.

Example, taken from the initGui.py script provided as example in this section:

def onProjectCreated():

    #Always create our icon viewer on project creation
    createIconViewer()


natron.settings.afterProjectCreated.set("onProjectCreated")
The After project loaded callback

This function is very similar to the After project created callback but is a per-project callback, called only when a project is loaded from an auto-save or from user interaction. The signature is:

callback(app)

You can set this callback in the project settings:

_images/projectCallbacks.png

This is a good place to do some checks to opened projects or to setup something:

def onProjectLoaded(app):

    if not natron.isBackground():
        if app.getUserPanel("fr.inria.iconviewer") is None:
            createIconViewer()

app.afterProjectLoad.set("onProjectLoaded")

Note

You can set a default After project loaded callback for all new projects in the Preferences–>Python tab.

The Before project save callback

This function will be called prior to saving a project either via an auto-save or from user interaction. The signature is:

callback(filename, app, autoSave)
  • filename : This is the file-path where the project is initially going to be saved.
  • app : points to the correct application instance being created.
  • autoSave : This indicates whether the save was originated from an auto-save or from user interaction.

Warning

This function should return the filename under which the project should really be saved.

You can set the callback from the project settings:

_images/projectCallbacks.png
def beforeProjectSave(filename, app, autoSave):
    print("Saving project under: ",filename)
    return filename

app.beforeProjectSave.set("beforeProjectSave")

Note

You can set a default Before project save callback for all new projects in the Preferences–>Python tab.

The Before project close callback

This function is called prior to closing a project either because the application is about to quit or because the user closed the project. The signature is:

callback(app)

This function can be used to synchronize any other device or piece of software communicating with Natron.

You can set the callback from the project settings:

_images/projectCallbacks.png
def beforeProjectClose(app):
    print("Closing project)

app.beforeProjectClose.set("beforeProjectClose")

Note

You can set a default Before project close callback for all new projects in the Preferences–>Python tab.

The After node created callback

This function is called after creating a node in Natron. The signature is:

callback(thisNode, app, userEdited)
  • thisNode points to the node that has been created.
  • app points to the correct application instance.
  • userEdited will be True if the node was created by the user (or by a script using the createNode(pluginID,version,group) function) or False if the node was created by actions such as pasting a node or when the project is loaded.

This is a good place to change default parameters values.

You can set the callback from the project settings:

_images/projectCallbacks.png
def onNodeCreated(thisNode, app, userEdited):
    print(thisNode.getScriptName()," was just created")
    if userEdited:
        print(" due to user interaction")
    else:
        print(" due to project load or node pasting")

app.afterNodeCreated.set("onNodeCreated")

Note

You can set a default After node created callback for all new projects in the Preferences–>Python tab.

This callback can also be set in the Node tab of any Group node (or PyPlug). If set on the Group, the callback will be invoked for the Group node and all its direct children (not recursively).

The Before node removal callback:

This function is called prior to deleting a node in Natron. The signature is:

callback(thisNode, app)

Warning

This function will NOT be called when the project is closing

You can set the callback from the project settings:

_images/projectCallbacks.png
def beforeNodeDeleted(thisNode, app):
    print(thisNode.getScriptName()," is going to be destroyed")


app.beforeNodeRemoval.set("beforeNodeDeleted")

Note

You can set a default Before node removal callback for all new projects in the Preferences–>Python tab.

This callback can also be set in the Node tab of any Group node (or PyPlug). If set on the Group, the callback will be invoked for the Group node and all its direct children (not recursively).

The Before frame render callback:

This function is called prior to rendering any frame with a Write node. The signature is:

callback(frame, thisNode, app)

To execute code specific when in background render mode or in GUI mode, use the following condition

if natron.isBackground():
    #We are in background mode

You can set the callback from the Write node settings panel in the “Python” tab.

_images/writePython.png

This function can be used to communicate with external programs for example.

Warning

Any exception thrown in this callback will abort the render

The After frame rendered callback:
This function is called after each frame is finished rendering with a Write node.

The signature is:

callback(frame, thisNode, app)

To execute code specific when in background render mode or in GUI mode, use the following condition

if natron.isBackground():
    #We are in background mode

You can set the callback from the Write node settings panel in the “Python” tab.

_images/writePython.png

This function can be used to communicate with external programs for example.

Warning

Any exception thrown in this callback will abort the render

The Before render callback:

This function is called once before starting rendering the first frame of a sequence with the Write node. The signature is:

callback(frame, thisNode, app)

To execute code specific when in background render mode or in GUI mode, use the following condition

if natron.isBackground():
    #We are in background mode

You can set the callback from the Write node settings panel in the “Python” tab.

_images/writePython.png

This function can be used to communicate with external programs for example.

Warning

Any exception thrown in this callback will abort the render

The After render callback:

This function is called once after the rendering of the last frame is finished with the Write node or if the render was aborted. The signature is:

callback(aborted, thisNode, app)
  • aborted : True if the rendering was aborted or False otherwise.
  • thisNode : points to the write node.
  • app : points to the correct application instance.

To execute code specific when in background render mode or in GUI mode, use the following condition

if natron.isBackground():
    #We are in background mode

You can set the callback from the Write node settings panel in the “Python” tab.

_images/writePython.png

This function can be used to communicate with external programs for example.

The After items selection changed:

For nodes that have an items table, such as RotoPaint or Tracker, this function is called when the item selection changed.

callback(thisNode,app, deselected, selected, reason)
  • thisNode: the node holding the items table
  • app: points to the current application instance
  • deselected: a sequence of items that were removed from the selection
  • selected: a sequence of items that were added to the selection
  • reason: a value of type NatronEngine.Natron.TableChangeReasonEnum

The variable reason will be set to a value of type NatronEngine.Natron.TableChangeReasonEnum depending on where the selection was made from. If reason is NatronEngine.Natron.TableChangeReasonEnum.eTableChangeReasonViewer then the selection was made from the viewer. If reason is NatronEngine.Natron.TableChangeReasonEnum.eTableChangeReasonPanel then the selection was made from the settings panel. Otherwise the selection was not changed by the user directly and results from an internal A.P.I call.

You can set the callback from the settings panel in the Node tab.

Rendering

To start rendering in Natron you need to use the render(effect,firstFrame,lastFrame,frameStep) or render(tasks) functions of the App class. The parameters passed are:

  • The writeNode: This should point to the node you want to start rendering with
  • The firstFrame: This is the first frame to render in the sequence
  • The lastFrame: This is the last frame to render in the sequence
  • The frameStep: This is the number of frames the timeline should step before rendering a new frame, e.g. To render frames 1,3,5,7,9, you can use a frameStep of 2

Natron always renders from the firstFrame to the lastFrame. Generally Natron uses multiple threads to render concurrently several frames, you can control this behaviour with the parameters in the settings.

Let’s imagine there’s a node called Write1 in your project and that you want to render frames 20 to 50 included, you would call it the following way:

app.render(app.Write1,20,50)

Note

Note that when the render is launched from a GuiApp, it is not blocking, i.e: this function will return immediately even though the render is not finished.

On the other hand, if called from a background application, this call will be blocking and return once the render is finished.

If you need to have a blocking render whilst using Natron Gui, you can use the renderBlocking() function but bear in mind that it will freeze the user interface until the render is finished.

This function can take an optional frameStep parameter:

#This will render frames 1,4,7,10,13,16,19
app.render(app.Write1, 1,20, 3)

You can use the after render callback to call code to be run once the render is finished.

For convenience, the App class also have a render(tasks) function taking a sequence of tuples (Effect,int,int) ( or (Effect,int,int,int) to specify a frameStep).

Let’s imagine we were to render 2 write nodes concurrently, we could do the following call:

app.render([ (app.Write1,1,10),
             (app.WriteFFmpeg1,1,50,2) ])

Note

The same restrictions apply to this variant of the render function: it is blocking in background mode and not blocking in GUI mode.

When executing multiple renders with the same call, each render is called concurrently from the others.

Using the DiskCache node

All the above can be applied to the DiskCache node to pre-render a sequence. Just pass the DiskCache node instead of the Write node to the render function.

Using the rotoscoping functionalities

All rotoscoping functionalities are gathered in the Roto class. For now, only the roto node can have a Roto object. The Roto object is auto-declared by Natron and can be accessed as an attribute of the roto node:

app.Roto1.roto

Beziers and layers can be accessed via their script-name directly:

app.Roto1.roto.Layer1.Bezier1

The script-name of the roto items can be found in the settings panel of the Roto node.

Moving items within layers

In Natron, all the items in a layer are rendered from top to bottom, meaning the bottom-most items will always appear on top of the others.

You can re-organize the tree using the functions available in the Layer class.

Warning

Removing an item from a layer or inserting it in a layer will change the auto-declared variable, e.g.:

fromLayer = app.Roto1.roto.Layer1 toLayer = app.Roto1.roto.Layer2 item = app.Roto1.roto.Layer1.Bezier1 toLayer.addItem(item)

#Now item is referenced from app.Roto1.roto.Layer2.Bezier1

Creating layers

To create a new BezierCurve, use the createLayer() function made available by the Roto class.

Creating shapes

To create a new BezierCurve, use one of the following functions made available by the Roto class:

  • createBezier(x,y,time)
  • createEllipse(x,y,diameter,fromCenter,time)
  • createRectangle(x,y,size,time)

Once created, the Bezier will have at least 1 control point (4 for ellipses and rectangles) and one keyframe at the time specified in parameter.

A Bezier initially is in an opened state, meaning it doesn’t produce a shape yet (unless it is a rectangle or ellipse). At this stage you can then add control points using the :func`addControlPoint(x,y)<NatronEngine.BezierCurve.addControlPoint>` function. Once you’re one adding control points, call the function setCurveFinished(finished) to close the shape by connecting the last control point with the first.

Once finished, you can refine the Bezier curve by adding control points with the addControlPointOnSegment(index,t) function. You can then move and remove control points of the Bezier.

You can also slave a control point to a track using the slavePointToTrack(index,trackTime,trackCenter) function.

A Bezier curve has several properties that the API allows you to modify:

  • opacity
  • color
  • feather distance
  • feather fall-off
  • enable state
  • overlay color
  • compositing operator

Most of them are available via a parameter, e.g.:

colorParam = bezier.getColorParam() bezierColor = colorParam.get(time)

Using the tracker functionalities

All tracking functionalities are gathered in the Tracker class. For now, only the tracker node can have a Tracker object. The Tracker object is auto-declared by Natron and can be accessed as an attribute of the tracker node:

app.Tracker1.tracker

The tracker object itself is a container for tracks. The Track class represent one marker as visible by the user on the viewer.

Tracks can be accessed via their script-name directly:

app.Tracker1.tracker.track1

The script-name of the tracks can be found in the settings panel of the Tracker node.

Getting data out of the tracks:

In Natron, a track contains internally just parameters which can hold animated data just like regular parameters of the effect class

You can access the parameters directly with their script-name:

app.Tracker1.tracker.track1.centerPoint

Or you can use the getParam(paramScriptName) function:

app.Tracker1.tracker.track1.getParam("centerPoint")

Here is an example that retrieves all keyframes available on the center point for a given track:

myTrack = app.Tracker1.tracker.track1

keyframes = []

# get the number of keys for the X dimension only and try match the Y keyframes
nKeys = myTrack.centerPoint.getNumKeys(0)
for k in range(0,nKeys):

    # getKeyTime returns a tuple with a boolean value indicating if it succeeded and
    # the keyframe time

    gotXKeyTuple = myTrack.centerPoint.getKeyTime(k, 0)
    frame = gotXKeyTuple[1]

    # Only consider keyframes which have an X and Y value
    # If Y does not have a keyframe at this frame, ignore the keyframe
    # getKeyIndex returns a value >=0 if there is a keyframe
    yKeyIndex = myTrack.centerPoint.getKeyIndex(frame, 1)

    if yKeyIndex == -1:
        continue

    # Note that even if the x curve or y curve didn't have a keyframe we
    # could still call getValueAtTime but the value would be interpolated by
    # Natron with surrounding keyframes, which is not what we want.

    x = myTrack.centerPoint.getValueAtTime(frame, 0)
    y = myTrack.centerPoint.getValueAtTime(frame, 1)

    keyframes.append((x,y))

print keyframes
Creating Tracks

To create a new track, use the createTrack() function made available by the Tracker class. You can then set values on parameters much like everything else in Natron.

User menu commands

In Natron you can add multiple menu commands that will then be available to the user via the menu. You can also assign it a shortcut and the user will be able to modify it via the shortcuts editor.

Project-wide menu commands:
_images/menuCommand.png

To add a project-wipe menu command to the application’s menu-bar, you need to use the addMenuCommand(grouping,function,key,modifiers) of the PyGuiApplication class to register it:

def createIconViewer():
    ...

#Add a custom menu entry with a shortcut to create our icon viewer
NatronGui.natron.addMenuCommand("Inria/Scripts/IconViewer","createIconViewer",QtCore.Qt.Key.Key_L,QtCore.Qt.KeyboardModifier.ShiftModifier)

Note that this function is to be called on the whole application via the natron variable and is not per-project unlike most functions that are generally called on the app object.

Warning

This function can only be called in the startup script init.py and will have no effect otherwise. This is not a dynamic function and will not create menu entries on the fly.

PySide panels

To create a non-modal panel that can be saved in the project’s layout and docked into the application’s tab-widgets, there is 2 possible way of doing it:

Generally you should define your panels in the initGui.py script (see startup-scripts). You can also define the panel in the Script Editor at run-time of Natron, though this will not persist when Natron is closed.

To make your panel be created upon new project created, register a Python callback in the Preferences–>Python tab in the parameter After project created. This callback will not be called for project being loaded either via an auto-save or via a user action.

#This goes in initGui.py

def createMyPanel():
    #Create panel
    ...

def onProjectCreatedCallback():
    createMyPanel()

Warning

When the initGui.py script is executed, the app variable (or any derivative such as app1 app2 etc…) does not exist since no project is instantiated yet. The purpose of the script is not to instantiate the GUI per-say but to define classes and functions that will be used later on by application instances.

Python panels can be re-created for existing projects using serialization functionalities explained here See the example below (the whole script is available attached below)

# We override the save() function and save the filename
def save(self):
    return self.locationEdit.text()

# We override the restore(data) function and restore the current image
def restore(self,data):

    self.locationEdit.setText(data)
    self.label.setPixmap(QPixmap(data))

The sole requirement to save a panel in the layout is to call the registerPythonPanel(panel,function) function of GuiApp:

app.registerPythonPanel(app.mypanel,"createIconViewer")

See the details of the PyPanel class for more explanation on how to sub-class it.

Also check-out the complete example source code below.

Using user parameters:

Let’s assume we have no use to make our own widgets and want quick parameters fresh and ready, we just have to use the PyPanel class without sub-classing it:

#Callback called when a parameter of the player changes
#The variable paramName is declared by Natron; indicating the name of the parameter which just had its value changed
def myPlayerParamChangedCallback():

    viewer = app.getViewer("Viewer1")
    if viewer == None:
        return
    if paramName == "previous":
        viewer.seek(viewer.getCurrentFrame() - 1)



def createMyPlayer():

    #Create a panel named "My Panel" that will use user parameters
    app.player = NatronGui.PyPanel("fr.inria.myplayer","My Player",True,app)

    #Add a push-button parameter named "Previous"
    app.player.previousFrameButton = app.player.createButtonParam("previous","Previous")

    #Refresh user parameters GUI, necessary after changes to static properties of parameters.
    #See the Param class documentation
    app.player.refreshUserParamsGUI()

    #Set a callback that will be called upon parameter change
    app.player.setParamChangedCallback("myPlayerParamChangedCallback")

Note

For convenience, there is a way to also add custom widgets to python panels that are using user parameters with the addWidget(widget) and insertWidget(index,widget) functions. However the widgets will be appended after any user parameter defined.

Managing panels and panes

Panels in Natron all have an underlying script-name, that is the one you gave as first parameter to the constructor of PyPanel.

You can then move the PyPanel between the application’s panes by calling the function moveTab(scriptName,pane) of GuiApp.

Note

All application’s panes are auto-declared by Natron and can be referenced directly by a variable, such as:

app.pane2

Panels also have a script-name but only viewers and user panels are auto-declared by Natron:

app.pane2.Viewer1
app.pane1.myPySidePanelScriptName

Controlling the viewer

The viewer in Natron Python API can be controlled much like any other nodes:

app1.Viewer1

Parameters in the Viewer interface inherit the Param class and can be retrieved by their script-name

app1.Viewer1.gain.set(2)

You can then control the player, the displayed channels, the current view, the current compositing operator, which are the input A and B, the frame-range, the proxy level and various other stuff with the parameters.

In GUI mode only, you can access the last viewer that was interacted with by the user:

viewerNode = app1.getActiveViewer()

You can redraw a viewer or re-render the viewer texture by calling the following functions:

# Refresh the viewer texture. This causes a re-evaluation of the node-graph.
# If the second boolean parameter is set to True, the render will not attempt
# to retrieve a texture from the cache if there is any.
app1.refreshViewer(viewerNode, False)

# Just redraws the OpenGL viewer. The internal texture displayed will not be
# re-evaluated.
app1.redrawViewer(viewerNode)

Natron Python FAQ

Here are a few frequently asked questions.

There may be more answers in the Natron forum, especially in the All About Natron Python Scripting topic.

Q: How can I get the location of the current Natron executable?

import sys
print(sys.executable)

Q: How can I get all widgets from a modal dialog?

PyModalDialog inherits from Qdialog, which inherits from QObject, which has a QObject::children() method.

Tutorials

This section provides basic and advanced tutorials on how to exploit Natron features using python.

Nodes

This section provides basic and advanced tutorials on manipulating nodes in Natron using python.

Get selected nodes label
import os
import NatronEngine
from NatronGui import *

def getSelectedNodesLabel():

  # get current Natron instance running in memory
  app = natron.getGuiInstance(0)

  # get selected nodes
  selectedNodes = app.getSelectedNodes()

  # cycle through every selected node
  for currentNode in selectedNodes:

    # get current node label
    currentLabel = currentNode.getLabel()

    # write node label in console
    os.write(1,'\n' + str(currentLabel) + '\n')

This script can now be saved in a .py file and added to Natron using the addMenuCommand(grouping,function) function in the initGuy.py file.

It can also be can executed directly in Natron’s script editor by adding:

getSelectedNodesLabel()

at the end of the script.

Get selected nodes class
import os
import NatronEngine
from NatronGui import *

def getSelectedNodesClass():

    # get current Natron instance running in memory
    app = natron.getGuiInstance(0)

    # get selected nodes
    selectedNodes = app.getSelectedNodes()

    # cycle through every selected node
    for currentNode in selectedNodes:

        # get current node class
        currentID = currentNode.getPluginID()

        # write node class in console
        os.write(1,'\n' + str(currentID) + '\n')

This script can now be saved in a .py file and added to Natron using the addMenuCommand(grouping,function) function in the initGuy.py file.

It can also be can executed directly in Natron’s script editor by adding:

getSelectedNodesClass()

at the end of the script.

Roto/RotoPaint

This section provides basic and advanced tutorials on manipulating the Roto/RotoPaint node using python.

Get items label in a Roto node
import os
import NatronEngine
from NatronGui import *

def getRotoItemsLabel():

  # get current Natron instance running in memory
  app = natron.getGuiInstance(0)

  # get selected nodes
  selectedNodes = app.getSelectedNodes()

  # cycle every selected node #
  for currentNode in selectedNodes:

    # get node class
    currentID = currentNode.getPluginID()

    # check if selected node(s) are of 'Roto' class
    if currentID == "fr.inria.built-in.Roto" or nodeID == "fr.inria.built-in.RotoPaint" :

      # get 'Roto' context
      rotoContext = currentNode.getRotoContext()

      # get 'Base layer' (root layer) in 'Roto' context
      baseLayer = rotoContext.getBaseLayer()

      # get all items in 'Base layer'
      allBaseLayerItems = baseLayer.getChildren()

      # cycle every item in 'Base layer'
      for item in allBaseLayerItems:

        # get current item label
        itemName = item.getLabel()

        os.write(1, '\n' + str(itemName) + '\n')

This script can now be saved in a .py file and added to Natron using the addMenuCommand(grouping,function) function in the initGuy.py file.

It can also be can executed directly in Natron’s script editor by adding:

getRotoItemsLabel()

at the end of the script.
