OpenTimelineIO (OTIO) is an API and interchange format for editorial cut information. You can think of it as a modern Edit Decision List (EDL). Existing interchange formats are either too limited or too complex. OTIO aims to be a “just right” level of complexity tailored to animation & visual effects pipelines. OTIO supports clips, timing, tracks, transitions, markers, metadata, etc. but not embedded video or audio. Video and audio media are referenced externally, not embedded. We encourage 3rd party vendors, animation studios and visual effects studios to work together as a community to provide adaptors for each video editing tool and pipeline.
