Adding VTT files to videos¶
In the filelist edit the metadata of a local video file. Add one or more vtt file and choose the appropriate track type
Track label A user-readable title of the text track which is used by the browser when listing available text tracks.
Track language Language of the track text data. It must be a valid BCP 47 language tag. (e.g. de, en, etc.)
Track type How the text track is meant to be used. (subtitles, captions, chapters, etc.)
Default attribute When active, adds the ‘default’ attribute to the rendered track.
Adding the default track is useful, for example if you wish to enable subtitle by default.
When adding multiple tracks, keep in mind that the default attribute should be set only for one track.
For YouTube, Vimeo and local videos you can set certain attributes which are added to the video tag in the frontend.
On mobile devices, videos typically need to be muted when autoplay is activated.
