What Is Video Average Play Time in Meta Ads?

Video average play time tells you, on average, how long each play of your video lasted. Meta adds up all the time the video spent playing, counts replays inside the same impression, and divides by how many plays started. Meta points to it as the metric to use when you want duration including replay time. That makes it a useful check on attention, as long as you remember it measures time spent, not how far through the video people got.

How does Meta calculate it?

Meta defines it as the amount of time spent playing your video, including replays for a single impression, divided by the total number of video plays.

The denominator, video plays, counts each time the video starts playing after an impression is counted, whether it autoplays or someone taps play. Meta doesn’t count a replay, such as pausing and starting again, as a new video play.

Why is my average play time longer than my video?

Because replays are in the numerator. If people loop or rewind a short video within one impression, all of that time is added, but the number of plays stays the same. Meta notes this directly: the reported average watch time can be longer than the length of the video.

How is it different from ThruPlays and 3-second plays?

Meta splits video metrics into duration metrics and milestone metrics, and calculates the duration ones in two different ways:

Metric	Type	Counts replayed seconds?
Video average play time	Duration	Yes, within a single impression
ThruPlays	Duration	No, unique seconds only
3-second video plays	Duration	No, unique seconds only
2-second continuous video plays	Duration	No, unique seconds only
Video plays at 25%, 50%, 75%, 100%	Milestone	Counts plays that reached the point, including skips

Meta says duration metrics are a proxy for how much of a video people consume, not just how much time they spend playing it. Video average play time is the exception Meta points to when you want duration including replay time.

How do you add it to your report?

1. In Ads Manager, open the Columns dropdown.
2. Choose Video engagement, or open Customize columns.
3. Add video average play time next to video plays and ThruPlays.
4. Click Apply, and save it as a column preset if you want to reuse it.

How should you read it next to other metrics?

Read it with a milestone metric. Average play time mixes first watches and replays into one figure, while the milestones show how many plays reached each point. Meta’s milestone metrics, such as video plays at 25%, also include people who skipped ahead to that point, so neither number alone tells the whole story.

FAQ

Does video average play time include people who scrolled past?

It divides by video plays, which Meta counts when a video starts to play after an impression, automatically or on tap. An impression without a play isn’t in the denominator. So the average describes plays that started, not every person who saw the ad in their feed.

Is average play time the same as average watch percentage?

No. Meta reports average play time in time, and it includes replays, so it can exceed the video length. To see how far people got through the video, use the milestone metrics: video plays at 25%, 50%, 75%, 95% and 100% of its length.

How are video metrics counted for a carousel ad?

Meta says that when you view video metrics for a carousel ad, they sum the total values for the videos in the ad. Video plays are counted separately for each video shown. You can view other performance metrics for each carousel card individually.
