What Are 3-Second Video Plays in Meta Ads?

3-second video plays is the Ads Manager metric for the opening of a video ad: it counts how often 3 seconds of your video played, or nearly all of a shorter clip. Meta also reports a cost per 3-second video play, and groups the metric with 2-second continuous video plays and ThruPlays as duration metrics.

How does Meta count a 3-second video play?

Meta counts a play when your video played for 3 seconds, or for 97% of its total length if the video is shorter than 3 seconds. Two details matter:

• It measures how much of the video played, not how much time passed while it was playing.
• Time spent replaying the video within a single impression is not included.

What do Meta’s examples show?

What happened	Counts as a 3-second play?
A 2-second video played for 1.94 seconds	Yes, that is at least 97% of its length
A 3-second video played for 2.91 seconds	Yes, that is 97% of its length
A 3-second video played for 2 seconds, rewound, and the first 2 seconds watched again	No, replays are not included

How is it different from 2-second continuous video plays?

The 2-second continuous video plays metric counts plays of 2 or more continuous seconds, and Meta says it only increments after 2 seconds have passed on the video player in real time. The 3-second definition instead talks about how much of the video played. Meta groups both, with ThruPlays, as duration metrics that sum unique seconds played, so time spent replaying the same segments in a single impression is not counted. Compare ads on one metric at a time.

What is cost per 3-second video play?

Meta calculates it as amount spent divided by 3-second video plays. For example, $150 spent for 30,000 three-second plays is $150 ÷ 30,000 = $0.005 per play.

What is hook rate?

Hook rate is an industry term, not a Meta metric. Advertisers usually calculate it as 3-second video plays divided by impressions, to see what share of impressions made it past the opening. Meta does not define it, so calculate it yourself from the two columns and label it clearly in your reports. Separately, Meta’s Instagram video best practices say to feature your brand and key message within the first 3 seconds and to hook viewers with motion or a compelling first frame.

FAQ

Does a 3-second play mean someone watched with sound?

No. Meta’s definition is about how much of the video played, and says nothing about sound. Meta’s Instagram best practices note that most people watch with the sound off, so design the first seconds to make sense visually, with on-screen text or subtitles.

Why are my 3-second plays higher than my ThruPlays?

They measure different depths. Meta counts a 15-second ThruPlay when someone watches at least 15 seconds, or 97% of a shorter video, so anyone who leaves between second 3 and second 15 adds a 3-second play but no ThruPlay. The gap is the plays that passed 3 seconds but not 15.

Can 3-second video plays include people who replayed the ad?

A replay does not add a second count within the same impression. Meta’s example: if someone plays a 3-second video for 2 seconds, rewinds and watches those 2 seconds again, it does not count as a 3-second video play, because replayed time is not included.
