notes

• Definition (en): WebVTT files are used for captioning or subtitling video content. It is a standard created by the World Wide Web Consortium (W3C) for displaying timed text, and is linked to the HTML5 element. The primary purpose of WebVTT files is to add text overlays to a video. Each time interval is specified in the format (HH:)mm:ss.xxx --> (HH:)mm:ss:xxx e.g. 00:00.000 --> 00:02.310 or 01:00:05.000 --> 01:00:07.000. The (HH:) is optional, but if included must have a minimum of 2 digits representing the hour (more than 2 digits may be used), and where both the minute (mm) and second (ss) parts must be between 00 and 59 inclusive.
