Creating WebVTT files for captions or chapters

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.

Information on barrier-free subtitle design and free software for creating subtitles can be found on the website of the project "BIK for All".

A finished file looks like this as an example:

Make sure you format your timestamps correctly and use the correct separators: hours:minutes:seconds.milliseconds. Also important are the blank lines between the elements and an additional blank line at the end of the file.
