Transcription

Use browse_assets to identify the video/audio asset and its transcription state.
For newly imported local media, complete the asset-import workflow first.
Check track_progress with target transcription. It returns current status; follow the returned check-back guidance and do not busy-loop.
Use find_transcript for timestamped text lookup.
Use the current caption tools to enable, inspect, translate, or style captions only after transcription is ready.

Do not call a transcription stuck from one pending status. Treat an explicit failed terminal state immediately; otherwise allow at least max(5 minutes, min(60 minutes, 2 x asset duration)), or at least 10 minutes across multiple checks when duration is unknown.

no_audio / no-speech is a successful terminal analysis result: the media is usable, but there is no transcript to read or caption. Do not report it as a transcription failure or retry it unless the user says the media contains speech that should have been detected.

Use trigger_transcript when the user explicitly wants transcription started or restarted. It is idempotent: only idle and error start work; ready, no-audio, and in-progress assets are left unchanged. If prepared transcription audio exists it is reused; otherwise the open Web/Desktop editor is asked to prepare and upload audio through its native pipeline. Then inspect readiness with track_progress.

For an idle or explicitly failed (error) run, call trigger_transcript with the asset id, then check transcription progress again. If an in-progress run has genuinely exceeded the stuck threshold, use manage_transcript action retry_transcription because trigger_transcript intentionally leaves in-progress work unchanged. The manage tool also remains available for low-level recovery where an external MCP host must supply prepared audioBase64. Repair source words with the transcript-fix action instead of rewriting visible captions when the source transcript itself is wrong.

For semantic speech edits, load talking-head-guide and use the Script workflow. Use mechanical cleanup only for fixed fillers and pauses; do not replace transcript-aware editing with destructive physical timeline cuts.
