VTT Subtitle Generator, answered.

How do I generate a VTT file? +

Upload audio or video above and choose VTT. Vocce transcribes with accurate timestamps and emits WebVTT — the SRT version comes along in the same job for free.

What's a VTT file vs SRT? +

WebVTT is the web-native caption format used by HTML5 video and most embedded players; SRT is the older universal format editors prefer. Same content, different headers and timestamp syntax.

Can I style VTT captions? +

VTT supports positioning and styling cues; we generate clean standard cues that all players accept, which you can then style with CSS where supported.

Are timestamps reliable on long videos? +

Yes — long files are chunked and stitched without drift, and low-confidence lines are flagged for quick review.
