Bookmarks allow you to create a quick access list of videos, so you can easily get back to video sections that you need to reference again. Click on the title of the video you wish to bookmark, then click on Bookmarks in the left-hand navigation menu (1). You can label your bookmarks (2) and see their timestamps (3). There’s a direct link to all your bookmarks when you click on See all your bookmarks (4).
You can find your “Bookmarked” tab in the video library of your Panopto account. This will show all videos with one or more bookmarks. Click a bookmark to open a video right to bookmarked time (you can also simply open the video itself). If you have more than one bookmark per video, they will be listed in chronological order.
