What the format rewards
Reels are ranked largely on how people respond to each video, not on how many followers the account has: whether they watch to the end, watch again and send it to someone. That rewards a strong first second, a single clear idea and endings that loop back to the start. Reels can run up to three minutes, but length is not a goal in itself. A product reveal usually lands in under twenty seconds; a tutorial can earn a minute. Decide the idea for the format first, then the length.
Safe zones and the interface
The Reels interface covers the bottom of the frame with the caption and audio line, and the right-hand edge with the like, comment and share buttons. Keep logos, prices and legal lines in the central area, clear of roughly the bottom 35 per cent (40 for legal lines, in Meta's ad guidance) and the right-hand strip. Generated compositions should be framed for this from the start, because moving text after the fact is where most adapted assets break: a price ends up under a button, or a disclaimer under the caption.
From a campaign master to Reels
Most brands do not need Reels invented from nothing; they need their campaign turned into Reels that feel native. The studio takes the master film and stills, re-frames them for 9:16 with the product kept exact, rewrites on-screen text and captions per market, and produces genuinely different openings to test. Approvals run on the whole set, so the fifteenth variant carries the same approved claims as the first, in every language.
What to keep human
Trends, sounds and cultural references move weekly, and they are where AI-made content most often looks late or tone-deaf. Keep a person deciding which trends the brand joins and which it ignores, and use generation for the production underneath: formats, versions and languages. Music is the other trap. Brand accounts should use commercially cleared audio rather than whatever is trending, which may not be licensed for business use.
