Progress flags
If you want to keep even better track of what part of the video people watch (or skip), you can add progress flags.
These behind-the-scenes markers divide your video into small segments. The viewer doesn't see or notice this setting. You set the progress markers to extract more info from the video statistics. You can see very precisely which points (flags) in the video have been viewed. Of course, also this feature is available per view session.
How to set up the progress flags
Go to the Video settings
Go to the tab Collect viewer data
Click on Add markers to track video progress
