Video Timeline Assembly and OpenTimelineIO Interoperability

Managing multi-cam video edits, cuts, and sequences across disparate NLE software requires standardized timeline exchange formats. Marquee structures video production logs and cut assemblies around OpenTimelineIO (OTIO) specifications.

Timeline Invariants

  1. Open Standard Interoperability: Cut lists and track sequences serialize into OTIO JSON format, avoiding proprietary vendor lock-in.
  2. Timecode-Accurate Frontmatter: In and out timecode points, frame rates (23.976, 24, 60fps), and resolution flags anchor directly in YAML frontmatter.
  3. Content-Addressed Media Links: Video clips reference immutable SHA-256 source files to ensure project reproducibility across machines.

OpenTimelineIO-backed markdown manifests guarantee lifelong edit portability across editing platforms.
