About this Viewer
The WebVTT Viewer reveals how captions will appear in HTML5 video players, making it easy to verify cue timing, ordering, and text.
Quickly inspect cues exported from authoring tools or generated from transcription services before embedding them on the web.
Use it to confirm speaker changes, cue lengths, and timing alignment for an accessible viewing experience.
Best Practices
- Ensure the file starts with the WEBVTT header on the first line.
- Use hh:mm:ss.mmm timestamps with periods separating milliseconds.
- Keep cue identifiers unique to avoid confusion in players.
- Include blank lines between cues for browser compatibility.
- Verify long captions are split into multiple cues for readability.
