When Regenerate is used to replace audio in a scene, Descript detaches the original video segment and inserts it as a standalone overlay layer to preserve video sync with the new audio. This is a reasonable mechanism, but it creates a downstream problem: these preserved video overlay layers are not treated as part of the scene's multicam/sequence layout logic. As a result, when a user subsequently applies a layout change to "all scenes," the preserved overlay layers do not update— they retain the layout state they had at the time Regenerate was run. Observed behavior: Playing through a composition that contains Regenerated clips causes the layout to visually revert to an older state mid-playback, creating jarring layout inconsistencies across scenes. Expected behavior: Video layers preserved by Regenerate should either (a) be enrolled in the same layout propagation logic as other scene layers, so that "apply to all scenes" updates them consistently, or (b) be re-linked to the sequence/multicam layer they originated from so they inherit layout changes automatically. Impact: This affects any user working with multicam or layout packs who also uses Regenerate to fix or refine audio — a common combination for polished podcast and interview-style productions. The workaround (manually updating each affected overlay layer) is tedious and error-prone, especially in longer compositions with many Regenerated clips. Suggested fix: When propagating a layout change across scenes, include detached video overlay layers that were created by regenerated audio in the update pass, treating them as equivalent to their source sequence layers for layout purposes.
