One thing worth adding for anyone running these as actual ads: AI UGC tends to fail on the first two seconds rather than the visuals. Real UGC opens mid-thought, slightly off-centre, imperfect audio - and that's what buys the scroll stop. Generated clips come out too composed and the polish reads as an ad instantly. I'd deliberately degrade the opening shot and keep the hook spoken rather than captioned. Also worth testing them against one real filmed control so you know what the AI version is actually costing you in hook rate, because the production saving isn't a saving if it halves your CTR.
