SRT vs WebVTT

SRT (SubRip) is the older, simpler format with sequential numbers and comma decimal separators (00:00:01,000). WebVTT (Web Video Text Tracks) is the W3C standard for HTML5 video, uses period decimals (00:00:01.000), starts with WEBVTT header, and supports cue settings like position, alignment, and styling.

Format differences

  • SRT uses comma decimals (00:00:01,000) and sequential cue numbers.
  • WebVTT uses period decimals (00:00:01.000) and a WEBVTT header.

Common uses

  • HTML5 video — convert legacy SRT to WebVTT for the <track> tag.
  • YouTube downloads — turn YouTube VTT back into SRT.
  • Editing — view and clean up timing in either format.
  • Workflow conversion — switch between authoring tools.
