An EXR plate header can carry optional editorial attributes (timeCode, reelName, framesPerSecond - assume 24 fps if absent - keyCode, imageCounter), an ASC framing decision list, camera identity and state, and acesImageContainerFlag (ST 2065-4 layout); renderingTransform and lookModTransform are deprecated. AMF is the ACES document for colour intent: it can travel with plates to describe how to view each one, but carries no timeline data (EDL/ALE may reference it), no demosaic settings, and an optional clipId link to material.
