OpenTimelineIO Editorial Interchange format and associated projects.

OpenTimelineIO

OpenTimelineIO Logo

OpenTimelineIO is an interchange format and API for editorial cut information. OTIO contains information about the order and length of cuts and references to external media. It is not however, a container format for media.

The OpenTimelineIO github organization is a federation of repos relating to the OpenTimelineIO core project.

Repositories stored in this organization include adapters, language bindings (except python, which is part of the core), examples, and more.

Support

These subprojects are part of the OpenTimelineIO project but may be supported differently than the OpenTimelineIO core.

This may include:

  • Repos primarily maintained by community members with OpenTimelineIO core team members only providing guidance
  • Repos provided for informational or archival purposes that aren't actively maintained

Please consult READMEs in individual subproject repos to learn more about their maintainance and support.
