Keep do/don't to a dozen lines: no other brands in frame, no music you do not own, no medical claims, no children if you did not arrange it, wardrobe colors that contrast the product, location you approved. Then state usage in plain language: organic, paid social, which platforms, how long, whether whitelisting or Spark is included, and what happens if you want to extend.
Vague 'usage for ads' is how you get a surprise invoice or a takedown when you boost the post. Name paid usage, paid duration, paid territories, and whether you need the raw files. If you plan to run the video from the brand account, Spark Ads, or creator whitelisting, that is a separate permission — put it in the brief and the contract, not in a follow-up after the footage is good. If you need to edit captions, crop ratios, or recut hooks, say you are buying an edit license, not only a posted video that cannot be touched.
Do not hide exclusivity in a footnote. If they cannot film a competitor for thirty days, write the window and the category. If they can, say that too so they do not over-quote you. Likeness for AI training or voice cloning is not implied by a UGC buy — if you even think you might need it, it is a separate yes. Keep the tone adult. A threatening don't-list makes people stiff on camera; a clear one makes them faster. Put the same usage paragraph in the invoice so finance and legal are not reading two different deals.
