How It Works

Generate a VTT in Three Steps

Turn the speech in your video into a valid WebVTT file, with nothing to time or format by hand.

Upload Your Video

Drop in an MP4, MOV, MKV, or WebM file. The spoken language is detected automatically, or you can set it yourself.

Generate the Subtitles

The speech is transcribed into timed lines with word-level timestamps. Translate the result if you need a localized track, and fix any line.

Export VTT

Download a standard .vtt file, correctly timed and formatted for web players and HTML5 video.

Capabilities

A Clean WebVTT, Generated for You

Valid WebVTT formatting for the web, accurate timing, and translation, without hand-writing a single cue.

WebVTT Format

A valid .vtt file for the HTML5 track element, web players, and streaming, formatted to the WebVTT spec.

Accurate Timing

Word-level timestamps keep every cue in sync with the speech, so captions land on the right moment.

Styling Cues

WebVTT supports positioning and styling, so web captions can sit where you want and match your player.

Translate the VTT

Turn the captions into any of 21 languages and export a separate VTT track for each region.

Edit Before Export

Fix the wording of a line or regenerate one that came through wrong before you download the file.

SRT and More

Need a different format? Export SRT, an After Effects project, a transparent overlay, or a burned-in video from the same project.

On the Web

Add a VTT File to an HTML5 Video

WebVTT is the caption format the browser understands natively. Reference the .vtt file from a track element inside your video, and the built-in player shows the captions with a toggle.

Drop the generated .vtt file into a standard HTML5 video

<video controls>
  <source src="video.mp4" type="video/mp4" />
  <track
    kind="captions"
    src="captions.vtt"
    srclang="en"
    label="English"
    default
  />
</video>
