On the content homepage for the video, click the ellipsis and select Edit.
The Edit content screen appears.
On the Edit content screen, select Display "Jump to" tab.
(Optional) If necessary, in the Rename "Jump to" tab to... field, edit the default name of the "Jump to" tab. By default, the "Jump to" tab is named Key Points.
In the Jump to points section, create one or more "Jump to” points. These are markers that users can click on, to quickly skip ahead to designated points in the video. For example, if your video is divided up into multiple sections, each focusing on a different topic, you might create a marker at beginning of each section, so that users can skip ahead to it.
Under Jump to points do the following:Using the MM:SS time format, enter the timestamp for the marker. For example, if you want users to be able to skip ahead to 00:10, enter 00:10.
[Optional] Enter a label for the marker. For example, if the marker allows users to skip ahead to the video’s introduction, you might enter Introduction. These labels help give users context for each marker.
If you want to create more “jump to” points, click +.
Click Save.
A tab containing displaying the “Jump to“ points you have specified, appears on the right-hand side of the video. Clicking on each of these points skips ahead and also reveals the video ahead. When a “jump to” point is clicked on, the transcript for that particular point is shown in the videotab.
