FAQ

What subtitle formats can I get?

Jobs produce timed subtitle artifacts (typically SRT/VTT-ready). Download links appear when the job completes.

Speech-to-text vs subtitle generator?

Speech-to-text focuses on readable text; this page focuses on timed caption files for publishing.

Can I translate the subtitles?

Yes — continue with the video translator or full workbench dub mode after transcription.
