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.

Chapter marker in a video
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.
Approach | Description |

Asset Editor | Enables creating chapters from your JWP dashboard |
.VTT file upload | Enables manually creating and uploading a Web Video Text Track file that defines each chapter in a video |

Use the following steps to create a .vtt file.
