From camera card to final delivery, which of timecode, reel/clip name, colour intent and lens data does each handoff have a documented place for?

Across the pipeline the slots differ: an ASC MHL manifest records file paths, sizes and hashes (optional custom metadata), not timecode or reel; AMF records the ACES colour pipeline and explicitly carries no timeline metadata such as edit points; OpenEXR offers optional timeCode, reelName and framesPerSecond attributes; the IMF Application 2E public page constrains colorimetry and references ST 2086 mastering-display metadata, with no timecode, ACES or CDL terms. Clip identity and timing therefore travel in ALE/EDL/EXR headers, colour intent in CDL/AMF/LUT sidecars, and lens data only as far as the camera records it. Curator qualifications: Specs read 2026-10-22; no files written or parsed. Avid MediaLog ALE column table not re-read (producer); Cooke /i document under prior no-distribution hold, not re-read. IMF page is the public SMPTE page, not the full standard. Limitations: Specs read 2026-10-22; no files written or parsed. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
