# How do CDL and LUT colour, tape/reel names and timecode move from dailies into editorial via ALE and EDL, and what does an OTIO conversion keep?

At the adapter pins, the OTIO ALE reader parses CDL (CDL, ASC_SOP, ASC_SAT columns) into clip CDL values while keeping other columns as metadata, and the CMX3600 EDL writer re-emits CDL as *ASC_SOP/*ASC_SAT comment lines from clip metadata (static reading).

At the adapter pins, the OTIO ALE reader parses CDL (CDL, ASC_SOP, ASC_SAT columns) into clip CDL values while keeping other columns as metadata, and the CMX3600 EDL writer re-emits CDL as *ASC_SOP/*ASC_SAT comment lines from clip metadata (static reading).

Curator qualifications: Silverstack, AMF guide and Avid MediaLog statements (E1-E3, E5, E7) not reinspected; vendor docs dynamic. Whether other ALE columns (Tape/Scene/Take) survive EDL write is the producer's code reading; not re-read in full. ASC CDL v1.2 primary text and an EDL comment-syntax standard remain unread (AUDIT1 row 16).

Limitations: Static reading.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
