About OpenColorIO
OpenColorIO (OCIO) is a color management solution for motion picture production, with a focus on visual effects and computer animation. It is designed to keep color consistent across different software and stages of a production pipeline.
Artists can use OCIO inside supported applications, which include tools for 2D, 3D, animation, compositing, editing, lighting, and rendering such as Blender, Nuke, Maya, Houdini, After Effects, and Unreal Engine. Studios can use the Python API to integrate OCIO into a pipeline or edit configuration files. Developers can use the Software Developer Guide to learn the framework or upgrade to OCIO v2. Version 2.5.0 adds Vulkan GPU renderer support, ACES 2.0 Built-In configs with Output Transforms as views, new color space attributes, and a preview of config merging.
It suits artists, studio pipeline teams, and developers working in film, animation, and effects. Support is available through Slack, mailing lists, and GitHub issues.
