Retention curve
Also called: Audience retention graph, Audience retention
Definition
A retention curve is a graph showing what share of viewers is still watching at each moment of a video, used to see where people drop off and what keeps them watching.
What “retention curve” means
The horizontal axis is the video’s timeline; the vertical axis is the percentage of viewers still watching. Every curve goes down over time, since people leave and few come back, but the shape tells a story. A steep drop in the first seconds means the opening didn’t hold; a gradual slope means steady interest; a sudden cliff in the middle points to a specific moment; a bump means people rewatched or skipped back to a part.
YouTube Studio shows audience retention for Shorts and long videos, and other platforms provide similar watch-time analytics with varying detail. Exact metrics and their names change over time, so check each platform’s analytics help for its current definitions.
Why it matters for short explainer videos
For short explainers, the retention curve is the most direct feedback on the script. A drop at second 2 is about the hook. A drop at a specific sentence usually means that line was confusing, too slow or didn’t have a strong visual. A rise at the end of a looping short can mean people watched it again.
It’s more useful than total views for improving your craft, because it points to exact seconds you can rewrite next time.
Example
A creator notices that their 90-second explainers lose a large share of viewers around second 20. Rewatching, they see that each video spends those seconds on a definition before showing why it matters. In the next videos, they move the “why it matters” line before the definition, and compare the new curves with the old ones.

How Motiongist handles it
Motiongist doesn’t show retention curves; those come from the platform where you publish. What it gives you is a way to act on them: edit the scene where viewers dropped, in the script or the storyboard, and re-run. A revision costs half the base price because only what changed is rebuilt.
Keeping scenes short and visual, which the engine does by design, helps, but no tool can promise a given retention.
