What does Descript document about Regenerate and Smooth jump cuts (inputs, supported footage, batch behaviour, review controls), and what would that mean for AI talking-head clips?

Problem. Text-based edits leave jump cuts; some tools repair them with AI. Conditions. Descript help pages (23 Oct 2026); English only; uses AI credits on current plans. Method (documented). Regenerate uses AI to smooth or rewrite parts of a video: heal jump cuts, tighten pacing, clean audio, or change what a speaker said (the last needs an authorised custom AI speaker). It currently supports English audio and video only. In video projects it regenerates Audio & video by default, with an Audio only option; sequences, B-roll, multi-speaker recordings and shots where the speaker's face isn't clearly visible cannot have video regenerated; Descript asks consent the first time because the process modifies a speaker's visual performance. Smooth jump cuts scans the whole composition and regenerates audio and video at each jump cut: Find first (lists every cut for review, recommended when the composition has intentional cuts such as scene changes or camera-angle cuts) or Smooth all (5 cuts per batch, queued); each result can be Reverted, Retried or Kept. Finish the rough cut first, because later edits create new cuts. It is audio-only on multi-track sequences. Edit boundaries mark where clips meet so you can Smooth them; if video regeneration is unavailable, it falls back to audio only. Use with AI footage [inference]: for generated talking-heads, a face that is not clearly visible or multiple speakers are unsupported cases, so plan cutaways (B-roll) or a J/L split edit (C3-B137-S29-03) rather than relying on regeneration; since Regenerate synthesises the speaker's face, record consent and disclosure per C3-B056-G20-07 if used. Failure modes. Uncanny results on retries; intentional cuts smoothed by Smooth all. Limitations. Result quality not shown in text; English only. Version/date. 2026-10-23. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Documentation only; effect quality and failure rates are not shown. Applicability to synthetic faces is inference. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
