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.

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 player when a standard WebVTT text track is provided in the player embed code.

JWP provides the following approaches to adding chapter markers to the videos in your media library.

.VTT file upload

If your content is uploaded or registered with the JWP dashboard, you can also host your VTT file on the JWP platform.

🚧

A .vtt file is subject to cross-domain security restrictions and therefore will not automatically load from another domain than the player.

Use the following steps to upload chapter markers:

1. Create a .vtt file for your chapter markers.
2. From your Media Library, click the name of the video to which to add chapter markers. The video details page appears.
3. On right side of the page beneath the preview player, click the Tracks tab.
4. In the Chapters section, click Manage. The Chapters Tracks panel appears.
5. Click Upload.
6. Select a single .vtt file or multiple .vtt files to open from your computer. The selected file or files are uploaded and associated with the video. Once uploaded, the track appears on the Chapters Tracks panel.
