VTT (WebVTT)
A subtitle format built for the web: similar to SRT, with a “WEBVTT” header and options for position and styling.
WebVTT (.vtt files) is the web’s standard subtitle format: the one the HTML5 video element uses to show text tracks. Inside it looks very like SRT, but it starts with the line “WEBVTT” and the milliseconds come after a full stop (“00:00:01.000”).
- SRT: the most compatible with editing software and video platforms.
- VTT: the natural choice for web players; supports position, alignment and notes.
- Most platforms accept both.
If you’re putting the video on your own website, VTT is the direct option. If you’re taking it into a video editor, SRT usually causes fewer problems.
Echo downloads subtitles as SRT and VTT from the same editor, with the same timings. More on the subtitles page and in how to add subtitles to a video.
