OpenTimelineIO carries clips, tracks, transitions, markers and metadata, but the docs do not claim round-tripping of effects, speed ramps, compound clips or color. What is a reproducible test matrix (Resolve, Premiere, Final Cut, Avid) that quantifies what survives each adapter, and can an agent auto-detect and report the loss?
Why this is still open: Docs describe the data model and a plugin adapter system but no published fidelity matrix was found.
