Natron is an open-source, cross-platform nodal compositing software.

    32 bits floating point linear colour processing pipeline.
    Colorspace management handled by the famous open-source OpenColorIO library.
    Dozens of file formats supported: EXR, DPX,TIFF, JPG, PNG…thanks to OpenImageIO.
    Support for many free and open-source OpenFX plugins:

            TuttleOFX : A suite of about 80 plug-ins made by a french studio named Mikros image.
            OpenFX-IO to read anything else than standard 8-bits images (bundled with pre-compiled

versions of Natron.

            OpenFX-Misc : A set of basic nodes, such as Transform, chroma keyer, etc… (bundled with

the pre-compiled versions of Natron.

            OpenFX-Yadif deinterlacer : An open-source efficient de-interlacer.
            OpenFX-Vegas SDK samples
            OpenFX samples (in the Support and Examples directories)


    Support for commercial OpenFX plugins: (these are proprietary software and not free)

            Furnace by The Foundry
            KeyLight by The Foundry
            GenArts Sapphire
            Other GenArts products
            And probably many more.
            Please tell us if you successfully tested other commercial plugins.

    OpenFX v1.3 supported : almost all features of v1.3 are supported (see Documentation/ofxActionsSupported.rtf and Documentation/ofxPropSupported.rtf in the source distribution)

    Intuitive user interface: Natron aims not to break habits by providing an intuitive and familiar user

interface.  It is possible to separate on any number of screens the graphical user interface.

    Performances:  Never wait for anything to be rendered, in Natron anything you do produces

real-time feedback thanks to its optimised multi-threaded rendering pipeline and its support

for proxy rendering (i.e: the render pipeline can be computed at lower res to speed-up rendering).

    Multi-task: Natron can render multiple graphs at the same time, it can also be used

as a background process in command-line mode without any display support (e.g: for render farm purpose).

    Recover easily from bugs: Natron sometimes crashes. Fear not, an  auto-save system

detects inactivity and saves your work for yourself. Also Natron provides the option to render

a graph in a separate process, meaning that any crash in the main application

would not crash the ongoing render (and the other way around).

     Project format written in XML and easily editable by human.
    Fast & interactive Viewer – Smooth & accurate  zooming/panning even for very large image sizes (

tested on 27k x 30k images).

    Real-time playback: Natron offers  a real-time playback with best performances thanks to its

RAM/Disk cache technology. Once a frame is rendered, it can be reproduced instantly afterwards, even

for large image sizes.

    Low hardware requirements: All you need is an x86 64 bits or 32 bits processor, at least

3 GB of RAM and a graphic card that supports OpenGL 2.0 or OpenGL 1.5 with some extensions.

    Animate your visual effects: Natron offers a simple and efficient way to deal with keyframes

with a very accurate and intuitive curve editor.

    Command line tool for execution of project files. The command line version is executable from ssh on a computer without any display. Hence it is possible to use a render farm to render Natron’s projects.

In the near future we will implement python bindings so that Natron can be scriptable and used only

from the command line.

Multi-view workflow: Natron saves time by keeping all the views in the same stream. You can separate

the views at any time with the SplitViews node. Note that currently Natron does not allow to split the

nodes settings for each view, this will be implemented in the future.

     Rotoscoping: Edit your masks and animate them to work with complex shots


Features for the next version:


    Tracker node: A new tracker will be embedded in Natron to track multiple points with different

algorithms available.

Features for future versions:

    Python scripting: Natron will be entirely scriptable, to operate with the node graph faster and

also to allow Natron to be used as a command-line tool only.

    Dope sheet: Well this is time we implement this, it can be very tedious to organise image sequences

without this very useful tool.

    Presets: As the scripting will be implemented, it will be easy for us to add Node presets that you can

share with others.

    Templates: Template nodes are an aggregation of several nodes put together as a graph that act

like a simple node. Share your templates and save time re-using them as part of other graphs.

    Deep data: Support for deep data (multiple samples per pixel)

System requirements:

Your system should have one of the following operating systems:

    Microsoft Windows ( Vista – 7 or 8 ).
    Apple MacOSX 10.6 or greater
    Any distribution of Linux with the following packages: Qt4/5 ,boost, OpenImageIO, OpenColorIO, FFmpeg, glew.

     A 32-bits x86 or 64-bits x86-64 processor.

      3 GB of RAM ( 8 GB recommended)
     5 GB (10 GB recommended) of disk space for caching and temporary files.
    Display with at least 1280 x 1024 pixel resolution and 24-bit color
     OpenGL 2.0 or OpenGL 1.5 with the following extensions





You can query the OpenGL version of your system in the about window of Natron (in the libraries tab).

     Platforms that do not support the GLSL would still run Natron but the Viewer would not support

the GPU acceleration.
