When producing multi-video-track shows using sequences and custom layouts, we regularly use the Regenerate (voice cloning) tool to fix small mistakes and mispronunciations in our recordings. This works well in the original composition. However, when we duplicate the composition to create social media clips — which requires changing the aspect ratio (e.g., landscape to portrait/square) or swapping to different layouts — the video in sections where Regenerate was used becomes broken or visually corrupted. The non-regenerated portions of the video survive the layout/aspect ratio change without issue. Steps to reproduce: Create a composition with a multi-video-track sequence and custom layouts Use Regenerate to fix a mispronunciation or small mistake in one or more sections Confirm the regenerated sections look and sound correct in the original composition Duplicate the composition Change the aspect ratio (e.g., from landscape to portrait) or apply a different layout pack Observe that the video in the regenerated sections is now broken/corrupted, while surrounding sections are fine Expected behavior: Regenerated audio segments and their associated video should gracefully survive aspect ratio changes and layout swaps, just like non-regenerated content does. Current workaround: Re-apply Regenerate on the affected sections after making the layout/aspect ratio change. This is time-consuming and impractical when a project has many regenerated sections across a long-form show. Impact: This significantly slows down our social media repurposing workflow. We produce shows with 500+ scenes and regularly use Regenerate throughout. Having to manually identify and redo every regenerated section each time we create a clip in a different format is not scalable. Requested improvement: Please ensure that Regenerate/Overdub segments are preserved and re-rendered correctly when compositions undergo aspect ratio or layout changes, so that content repurposing across formats works seamlessly without requiring re-regeneration.
