The first second names an action: comment your sign, guess the price, stitch this with your version, drop a yes or no. That is a first-second hook whose payoff is participation rather than a product beat. Hook rate still grades whether anyone stayed. Pattern interrupt is the muscle — a question on screen is a change from the talking head the thumb just saw. It is not a growth hack. It is an open, and it can be empty.
A prompt that only works if the viewer already cares ('what should I post next') is a following-tab line wearing a home-feed costume. A prompt that is the content ('which of these two packs is the real SKU') can stop a stranger. Burn the question into the frame. Mute autoplay will not wait for the voice to ask it. The comments you get are then a second object: a stitching-comment pass can turn one of them into the next hook.
Platforms have spent years demoting obvious engagement bait. A file whose only idea is 'comment for part two' trains a skip. If the body never pays the question off, the comments are a tax on people who stayed. Use the prompt as frame one of a brief that still has proof, a pack shot, or a claim — then measure hook rate, not comment count, when you decide whether the open worked.
In practice
- Put the question on screen in second one. Do not ask it only in the caption field.
- Pay the question off in the body. A prompt with no answer is a skip wearing a CTA.
- Judge the open on hook rate. Comment count is a downstream pile, and it is easy to farm.
The mistake to avoid
Shipping 'comment yes for the link' as the entire hook and calling the comment count a creative win. The ranker has seen that line.
