WebVTT, or Web Video Text Tracks, is a file format used to create text tracks for video content on the web. These tracks can include subtitles, captions, descriptions, chapters, and metadata. The format is designed to be simple and easy to use, making it accessible for both developers and content creators.

A WebVTT file is a plain text file with a .vtt extension. It consists of cues, which are time-stamped segments of text that are displayed at specific points in the video. Each cue includes a start time, an end time, and the text to be displayed. The file also includes a header, which specifies the format and encoding of the file.

WebVTT files are used in conjunction with HTML5 video and audio elements. They are referenced in the video or audio tag using the "track" element, which specifies the source of the text track and its kind (e.g., subtitles, captions). When the video or audio is played, the browser automatically displays the appropriate text track based on the current time.

WebVTT is supported by all major web browsers, making it a widely used format for adding text tracks to web-based video content. It is also supported by many video players and platforms, including YouTube, Vimeo, and HTML5-based players.
