Overview

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

OTIO includes both a file format and an API for manipulating that format. It also includes a plugin architecture for writing adapters to convert from/to existing editorial timeline formats. It also implements a dependency- less library for dealing strictly with time, opentime.

You can provide adapters for your video editing tool or pipeline as needed. Each adapter allows for import/export between that proprietary tool and the OpenTimelineIO format.

Use Cases

• I have a timeline in Adobe Premiere, and I want to bring that cut into my in-house animation system.
• I have a timeline in Avid Media Composer, and my Producer wants to know a full list of the media I'm using.
• I am about to render a bunch of shots & I want to make sure my frame ranges match what Editorial is asking for (not too long or too short).
• The Editor just added some cross dissolves and I need to know how many more frames (at head or tail) of which shots need to be rendered.
• Legal needs a list of all the audio we're using (music, effects, dialogue) in the current cut.
• TDs/Animators want to get a cut from Editorial for reference, and then splice their updated renders/recordings into that cut.
• Editorial is working with proxy media (QuickTime, MXF, etc.) and I want to gather all the EXRs that correspond with that & bring those into Nuke.
