Subtitle export options

Available exports depend on the editor and project type. Burn-in requires a video; a subtitle document alone does not contain a media track.

In Studio, media projects and timed subtitle documents can also be exported as DOCX, JSON, CSV and HTML transcripts, without Ultimate. TXT drafts require confirmation of the suggested timings first.
