Creating WebVTT files for captions or chapters


WebVTT files are small text files that contain metadata synchronized with audio or video content. For example, the files contain information about which subtitles should be displayed in a given time period when the video is playing, or where a new chapter begins.

WebVTT files can easily be created in a text editor (e.g. Windows: Notepad, Mac: TextEdit). The file extension must be set manually to .vtt when saving. If you want to create WebVTT files for Camtasia screencast videos, see the instruction Share Camtasia videos with chapter track.
