Add chapter markers

A chapter marker provides a way to convey viewing milestones within the timeline of a player. It allows the segmentation of long videos into discrete segments.

Example of channel markers

A viewer can quickly hover over the cue point and can see the title of the chapter or section. Clicking on the cue point navigates you directly to that point of the video. These markers are rendered by the JWP when a standard WebVTT text track is provided in the player embed code.

Create a .VTT file

Use the following steps to create a .vtt file.

  1. In a text editor, create a new file.
  2. Add information for cue timings and chapter titles. Cue identifiers are optional.
  3. Save the file.


A .vtt file should always be saved in UTF8 encoding to prevent character issues.

A .vtt file is subject to cross-domain security restrictions and therefore won't automatically load from another domain than the player. See Crossdomain File Loading for more info.
