A duet or stitch-style clip: the creator reacting to something else on screen, with their response as the content.
When to use it
For responding to a trend, a competitor, a review or a piece of news quickly. Its value is speed — a reaction is only worth running while the thing being reacted to is still live.
The thing to get right
Only three beats, deliberately. Reactions are short because the source material is doing half the work, and stretching one to a full ad length drains it.
The format at a glance
- Output — a video ad.
- Structure — 3 beats, each one a separately planned shot.
- Family — Creator & UGC video.
- Recipe id — reaction, which is what you name when you ask for it by hand or from an agent.
Why is it only three beats?
Because the source material is doing half the work. Stretching a reaction to full ad length drains it, so the cap is the format rather than a limitation of it. If you need longer, the thing being reacted to is not strong enough.
