What fits in a 15-second video
For a social teaser, a bumper ad or the hook of a Reel or Short, plan a 3-second hook, one visible result for about 8 seconds and a 4-second call to action. At about 15 words per spoken sentence, 36 words is roughly 2 sentences. Leave about a tenth of the time silent so each screen lands: aim for about 32 words rather than 36.
