![]() Full support of the OpenFX 1.4 API, enabling use of open source or commercial plug-ins.Support for reading and writing video files through the FFmpeg library, including digital intermediate formats such as DNxHD and Apple ProRes.Additional image layers can be used to store several color layers, or for non-color information such as depth, optical flow, binocular disparity, or masks. Support for many image formats, using OpenImageIO, including multi-layer OpenEXR.Color management is handled by the OpenColorIO library, including support for the ACES color encoding system proposed by the Academy of Motion Picture Arts and Sciences.Support for multi-core architectures: all processing is multithreaded using a thread pool pattern.32 bit floating point linear color processing pipeline : all frames are represented as floating-point RGBA samples with premultiplied alpha, permitting the use of alpha compositing operators defined by Thomas Porter and Tom Duff.A graphic card that supports OpenGL 2.0 or OpenGL 1.5 with a few commonly available extensions ( ARB_texture_non_power_of_two, ARB_shader_objects, ARB_vertex_buffer_object, ARB_pixel_buffer_object). ![]() Low hardware requirements: a 64 bit processor, at least 3GB of RAM (8GB recommended).Closed-source plug-ins, including commercial ones, can still be used with Natron, although the GPL according to the FSF does not allow loading and linking closed-source plug-ins, or plug-ins that are not distributed under a GPL compatible license, but they have to be distributed separately.ĭata produced by Natron, or any software distributed under the GPL, is not covered by the GPL: the copyright on the output of a program belongs to the user of that program. All plugins that are distributed with binaries of Natron 2.0 or later have thus to be compatible with the GPLv2. Since version 2.0, the software was relicensed under the GNU General Public License version 2 or later to allow better commercialization. Licensing īefore version 2.0, Natron was licensed under the Mozilla Public License version 2.0, which allowed redistributing it with closed-source plug-ins. In January 2015, the Art and Technology of Image (ATI) department in Paris 8 University announced that they would switch to professional-quality free and open-source software for teaching computer graphics to students and artists, including Blender, Krita and Natron. Version 1.0 was released on December 22nd, 2014, together with a large sample project by François "CoyHot" Grassard, a professional computer graphics artist and teacher, demonstrating that Natron could execute interactively graphs with more than 100 nodes. Subsequent beta releases brought additional features such as motion blur, color management through OpenColorIO, and video tracking. The first widely available public release was 0.92 (June 6th, 2014), which brought rotoscoping and chroma keying functionalities. The prize was a 12-month employment contract to develop Natron as a free and open-source software within the institute. The project was the winner of the 2013 Boost Your Code contest by Inria. Natron was started by Alexandre Gauthier in June of 2012 as a personal project. Natron is named after Lake Natron in Tanzania which, according to Natron lead programmer Alexandre Gauthier, provides "natural visual effects" by preserving its dead animals. Most open-source and commercial OpenFX plug-ins are supported. Natron supports plugins following the OpenFX 1.4 API. ![]() It has been influenced by digital compositing software such as Avid Media Illusion, Apple Shake, Blackmagic Fusion, Autodesk Flame and Nuke, from which its user interface and many of its concepts are derived. Natron is a free and open-source node-based compositing application. ![]()
