Scroll stopper - the craft term for whatever wins the first frame

A scroll stopper is the device in an ad's opening frames whose only job is to interrupt a scroll: a motion, a texture, an unexpected object, a line of text that reads as a statement, not a sale. Most teams use "scroll stopper" and "hook" interchangeably, and hook rate is named for the stop. We separate the two here, as an editorial convention rather than settled vocabulary, because the jobs fail separately: the scroll stopper is the interrupt, the hook is the promise that makes the interrupt worth having, and an ad can stop the scroll and still lose the viewer at second two. Stopping and holding are two different jobs, and the second one is where openings usually fail.

The Devices That Recur

• Pattern interrupt: motion or framing that does not belong in a feed: an object entering frame, a hard zoom, an unfinished action.
• Texture shock: a close-up of something tactile or messy at a scale the viewer is not used to seeing.
• Problem callout: naming the viewer's situation in the first line, so the ad reads as being about them.
• Curiosity gap: showing the result before the method, so leaving costs the viewer the answer.
• Bold claim: a specific, checkable number instead of a superlative.

Those five are not a shortlist drawn up for this page. They are five of the eight opening types the current analysis contract classifies an opening against; question and social proof are the other two, and anything that fits none of them is filed as other instead of being given a new name.

Worked Example

Two openings for the same cleaning product. The first: a clean bottle on a counter with the brand name on screen. The second: a phone-shot close-up of a stained sink filling the whole frame, no text for the first second. The second stops scrolls because it is a texture the feed does not usually serve, and because nothing in the first second looks like advertising. It buys the hook the extra second it needs to make its promise.

Recording an Opening So It Can Be Reused

The reason "scroll stopper" stays vague in most teams is that openings get described instead of recorded. Admetra treats the opening as a reusable part: it carries a declared job, a device drawn from a fixed vocabulary, and the pacing signature - cut density and motion energy - recorded alongside it. That is what makes it possible to say a device works, instead of saying that a video worked.
