Bookmark adds named time points (chapters) to a video. A viewer can select a chapter to jump to that moment, and a shared URL can start at the selected time.

1. Sign in and open Video Manager/My Videos.
2. Find a video you can edit and select Add Bookmark.

3. Play or seek to the desired time.
4. Enter the time and a short chapter title.
5. Select Add and repeat for the remaining chapters.

Open the chapters/bookmarks control in the player or select a timestamp listed on the video page. The player seeks to that moment and the URL can include a t= time value.

Why is Add Bookmark missing? Confirm the plugin is enabled and that the account can edit the video.

Why does a chapter start slightly early or late? Check the saved time and the source video's seeking/keyframe behavior.

Can I share one chapter? Open the chapter and copy the updated video URL. The recipient must still have permission to watch the video.
