Cross-platform open-source compositing software.


It offers robust and efficient tools for compositors to get their job done fast with high quality results.

  • 32 bits floating point linear color processing pipeline.
  • Colorspace management handled by OpenColorIO.
  • Dozens of file formats supported: EXR, DPX, TIFF, PSD, SVG, RAW, JPG, PNG … and more.
  • Support for OpenFX v1.4
  • Support for many free and open-source OpenFX plugins:
  • 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-Arena : A set of extra nodes (bundled with the pre-compiled versions of Natron).
  • OpenFX-OpenCV : A set of plugins based on OpenCV.
  • OpenFX-Yadif deinterlacer : An open-source efficient de-interlacer.
  • OpenFX-Vegas SDK samples
  • OpenFX samples (in the Support and Examples directories)


  • 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. It supports Retina screens on MacOSX.
  • 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 and make use of 100% of the compute power of your CPU.
  • Network rendering: Natron can be used as a command-line tool and can be integrated on a render farm manager such as Afanasy.
  • NatronRenderer: A command line tool for execution of project files and python scripts. The command line version is executable from ssh on a computer without any display.
  • 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 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 1.5+ with some extensions.
  • Motion editing: Natron offers a simple and efficient way to deal with keyframes with a very accurate and intuitive curve editor. You can set expressions on animation curves to create easy and believable motion for objects. Natron also incorporates a fully featured dope-sheet to quickly edit clips and keyframes in time-space.
  • 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 OneView node.
  • Rotoscoping/Rotopainting: Edit your masks and animate them to work with complex shots
  • Tracker node: A point tracker is  embedded in Natron to track multiple points. Version 2.1 of Natron will incorporate the Tracker from Blender.
  • Presets: Nodes presets can be imported/exported easily with an XML file format
  • Python scripting: Natron has made available via its Python API most of its functionnalities.
    Natron embeds a Python 2.7 interpreter that can be used to customize the application. .
  • Multi-plane: In Natron all layers read from EXR’s, TIFF’s or PSD’s are available as planes that each node can access. You can also freely create your own custom planes. This allows for cleaner graphs and more efficient work.


Next version: (2.1)

  • Nodegraph enhancement: The node graph will be re-written to use OpenGL instead of the current Qt QGraphicsView framework. This will fix most of the interaction bugs that currently exist with the node graph implementation.
  • Blender’s tracker (LibMV) integration: New tracker node based on Blender’s one. The user interface will remain close to what the user interface of the current tracker is.
  • Read/Write meta-nodes: All Reader nodes and Writers will now be part of the single Read/Write node so it is easier for users to import and export images. If 2 Readers can read the same file type, for instance ReadPSD and ReadOIIO can both read .psd files, then a Decoder drop-down will allow the user to pick which one he/she wishes to use.

Future versions:

  • Optical Flow nodes: VectorGenerator, Motion Blur, Retimer, RollingShutter
  • Natural matting: Extract a foreground of an image without necessarily a green/blue-screen background.
  • Deep data: Support for deep data (multiple samples per pixel)
  • 3D workspace: The 3D workspace will first be in fact only 2.5D: That is support for Cards onto which are projected textures. Then it will also support 3D projection of textures through a camera as well as UV editing for 3D match-moving.
