SRT Subtitle Generator, answered.

How do I generate an SRT file from a video? +

Upload audio or video above and choose subtitles. Vocce transcribes the speech and emits SRT and VTT files with accurate timestamps, plus the full transcript.

What's the difference between SRT and VTT? +

SRT is the classic format most editors and players accept; VTT is the web-native flavor used by HTML5 video. Vocce exports both from the same job.

Are the subtitle timestamps accurate? +

Yes — timestamps come straight from the recognition engine, and long files are stitched without drift. Low-confidence lines are flagged so you can review just those.

Can I translate the subtitles afterwards? +

Yes — pair this with the Subtitle Translator tool to localize SRT/VTT files while keeping the original timeline intact.
