Adapters

While OpenTimelineIO favors the .otio JSON format, Python OpenTimelineIO supports many file formats via adapter plugins.

Built-In Adapters

The OpenTimelineIO native file format adapters that are present in the opentimelineio python package are:

• otio_json - OpenTimelineIO’s native file format.

• otiod - a directory bundle of a .otio file along with referenced media.

• otioz - a zip file bundle of a .otio file along with referenced media.

Batteries-Included Adapters

To also install a curated list of additional useful adapters, use the OpenTimelineIO-Plugins python package. In addition to the OpenTimelineIO native adapters, you’ll get aditional useful adapters including:

• AAF

• ale

• burnins

• cmx_3600

• fcp_xml

• fcpx_xml

• hls_playlist

• maya_sequencer

• svg

• xges

These adapters are supported by the broader OpenTimelineIO community. While the OTIO core team consults and sometimes contribute to their development, they may be maintained and supported at varying levels.

Additional Adapters

Below are some other adapters that may be useful to some users:

• kdenlive

Custom Adapters

Adapters are implemented as plugins for OpenTimelineIO and can either be registered via an environment variable or by packaging in a Python module with a particular entrypoint defined. For more detail, see the Writing an OTIO Adapter tutorial.
