Static ads: let the visual carry it
The workhorse formats are the product hero — dramatic light, dark reflective surface, one product — and the promo banner with bold color blocking and clean copy space. Prompt the copy space explicitly ('clear empty space on left third') so your headline has somewhere to live.
When you want type baked in, Recraft v4.1 is the typography specialist: prompt the actual headline text in quotes, keep it short, and treat it as display type for a title card. Nano Banana Pro is the pick when fine text and 4K detail both matter.
Video hooks, honestly sized
Generated clips run a few seconds each — the length of a hook, not a film, and the length that feeds actually reward. Structure for the first second: a CRASH ZOOM product reveal, a ZOOM PUNCH on a reacting face, or a hand lifting the product to camera in vertical UGC style on Seedance Pro.
For a talking-head ad, the pipeline is real and three steps long: generate the presenter still, generate the voiceover line with a preset TTS voice on the audio page, then drive the face with InfiniTalk in the lipsync studio. For sequences beyond one beat, use multi-shot on Kling 3 or stitch clips in your editor.
Iterate like a media buyer
Volume testing is the point of generating creative. Hold the product constant and vary one axis per batch — backdrop color, hook framing, lighting mood — so when a variant wins you know why. Draft the batch on a cheap fast model like FLUX Schnell, then re-render the winners on FLUX Pro or Seedream v4.5 for finals.
The /apps library ships ad-shaped workflows if you'd rather start from a template: Six-Second Ad, Ad Reel, Flash Sale Banner, Product Hero, Sale Hype Reel. Each is a tuned prompt you can run as-is or fork.
