OpenColorIO

Introduction

OpenColorIO (OCIO) is a complete color management solution geared towards motion picture production with an emphasis on visual effects and computer animation. OCIO provides a straightforward and consistent user experience across all supporting applications while allowing for sophisticated back-end configuration options suitable for high-end production usage. OCIO is compatible with the Academy Color Encoding Specification (ACES) and is LUT-format agnostic, supporting many popular formats.

OpenColorIO is released as version 2.0 and has been in development since 2003. OCIO represents the culmination of years of production experience earned on such films as SpiderMan 2 (2004), Surf's Up (2007), Cloudy with a Chance of Meatballs (2009), Alice in Wonderland (2010), and many more. OpenColorIO is natively supported in commercial applications like Katana, Mari, Nuke, Maya, Houdini, Silhouette FX, and others.

OpenColorIO is free and open source software (LICENSE), and one of several projects actively sponsored by the ASWF (Academy Software Foundation).

OpenColorIO Project Mission

The OpenColorIO project is committed to providing an industry standard solution for highly precise, performant, and consistent color management across digital content creation applications and pipelines.

OpenColorIO aims to:

• be stable, secure, and thoroughly tested on Linux, macOS, and Windows
• be performant on modern CPUs and GPUs
• be simple, scalable, and well documented
• be compatible with critical color and imaging standards
• provide lossless color processing wherever possible
• maintain config backwards compatibility across major versions
• have every new feature carefully reviewed by leaders from the motion picture, VFX, animation, and video game industries
• have a healthy and active community
• receive wide industry adoption

Acknowledgements

OpenColorIO represents the generous contributions of many organizations and individuals. The "Contributors to the OpenColorIO Project" copyright statement used throughout the project reflects that the OCIO source is a collaborative effort, often with multiple copyright holders within a single file. Copyright for specific portions of code can be traced to an originating contributor using git commit history.

OpenColorIO was originally developed and made open source by Sony Pictures Imageworks. The core design, and the majority of OCIO 1.0 code was authored by Imageworks, who continue to support and contribute to OCIO 2.0 development.

The design and development of OpenColorIO 2.0 is being led by Autodesk. Autodesk submitted a proposal to revitalize the project in 2017, and have authored the majority of OCIO 2.0 code in the years since.

Significant contributions have also been made by Industrial Light & Magic, DNEG, and many individuals. See Contributors for a complete list.
