The curve is read by its shape, not its average. A cliff in the first seconds is a hook problem and nothing later in the video can fix it. A steady, gentle slope means the pacing is holding. A flat section followed by a drop points at one specific beat — usually the moment the video stops delivering and starts explaining. On looping formats the line can rise, which is the signature of people watching twice rather than of anything new happening.
It is the metric that most reliably separates a video that was watched from a video that was served. Impressions are bought or given; retention is earned per second, which is why distribution systems weight it so heavily and why lengthening a video almost always costs more than it gains.
Versely reports at the post level rather than per second — an analytics overview across your connected accounts, plus a breakdown by platform and by format that says which shapes of post are actually working for you. The second-by-second curve lives in each platform's own studio; what you bring back here is the decision it implies: a shorter cut, a different opening, a beat removed.
In practice
- Cut to the length the material supports rather than to the length the format allows.
- Every beat should change something on screen — a new shot, a new claim, a new number — or it is where the curve bends.
- Compare curves between two cuts of the same script; comparing across different videos mostly measures the topic.
The mistake to avoid
Chasing average view duration by making videos shorter and shorter. A short video with nothing in it retains percentage points and loses the audience anyway, because the number that pays is attention, not the ratio.
Where you will run into it
- Trim a Video — Keep the part you want. Drop the rest.
- Cut a Section Out of a Video — Skip the bad take. Keep everything else.
- Convert a Video to Shorts — Find the best 30 seconds. Reformat it. Post it.
- AI Reel Maker — Hook, beats, captions, posted.
- AI Social Media Video Generator — Made for the feed it posts to, then posted to it.

Hook rate
Hook rate is the share of people shown a video who are still watching a few seconds in — the number that grades the opening, not the edit behind it.
Duration
Duration is how long a generated clip runs, chosen before generation from whatever lengths the model supports rather than trimmed afterwards.
Content repurposing
Repurposing is turning one finished piece into the several format-native cuts each platform expects, rather than posting the same file to all of them.
Burned-in captions
Burned-in captions are subtitles rendered into the video's pixels, so they cannot be switched off, restyled by the player, or lost when the file is re-uploaded somewhere else.
Creative fatigue
Creative fatigue is performance decaying because the audience has seen the same piece too many times, rather than because anything about the piece changed.
