Natron Nodal compositing software to produce visual effects added to Video directory.

Natron is a free open-source, cross-platform compositing software. It aims to produce visual effects.

  • 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. and FFmpeg.
  • 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
  • OpenFX v1.3 supported : all features are supported
  • 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. You can set expressions on animation curves to create easy and believable motion for objects.
  • 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.
  • 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. 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
  • Tracker node: A tracker is embedded in Natron to track multiple points with different algorithms available.
  • 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 3.4 interpreter that can be used to customize thoroughly the application. Read the documentation at natron.rtfd.org.

  • Multi-plane: In Natron all layers read from EXR’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.
