How to Translate VTT Subtitles Without Breaking WebVTT Timing

Translate VTT subtitles while preserving WebVTT headers, cue timestamps, cue settings, speaker labels, and caption order.

Step-by-step workflow

  1. 01Keep the WEBVTT header and metadata lines unchanged.
  2. 02Preserve cue timestamps, cue identifiers, and cue settings.
  3. 03Translate caption text while checking reading speed and line length.
  4. 04Compare source and target cue counts before export.
  5. 05Preview the translated VTT file in the target video player.

What to protect during translation

  • The WEBVTT header, NOTE blocks, cue identifiers, timestamps, and cue settings.
  • Speaker labels and meaningful inline tags.
  • Cue order and blank lines between cues.

Pre-export checks

  • Load the VTT file in the target video player.
  • Compare cue counts and timestamp formats.
  • Check caption readability on desktop and mobile player sizes.

Common mistakes to avoid

  • AvoidEditing cue timing syntax or cue settings during translation.
  • AvoidRemoving notes or metadata that the video workflow expects.
  • AvoidTranslating captions without previewing readability in the video player.
