Cut Marks to Smil Workflow Operation

ID: cut-marks-to-smil

Description

This operation parses a JSON containing cut marks into a SMIL that can be used by the Video Editor. It does this by attributing the given times to the specified tracks.

Tracks are assumed to start at 0. Likewise, cut marks are assumed to be specified relative to the beginning of the tracks.

The cut marks must be a media package attachment. For compatibility to early versions, the code falls back to looking for catalogs if no attachment was found.
