We provide second by second reports on a particular viewing session. Based on this data, we pull together engagement and duration estimations showing how many of your viewers got to certain points in your video. (Note: These reports are available for Pro, Business, and Premium members only.)
On the engagement graph, each play is tracked from the point of the video when the user starts watching (usually 0:00, but sometimes later) to the maximum timestamp we’re able to detect (within a single browser session).
The duration graph calculates the percentage of viewers who got to a certain point in your video by assuming that all plays started at 0:00 and looking at the maximum timestamp that we’re able to detect.
We can account for parts skipped in a viewing session which means some graphs may slope downward and then upward again towards the end. Viewers scrubbing back on the video will not change the shape of the graph.
