Notes for cleaner ad outputs

Keep the dialogue line short. One line works better than a full sentence in 5 seconds.
If the model invents overlay text, repeat: “no on-screen text” and avoid mentioning brands.
For more product focus, add: “close-up on sunscreen bottle” or “logo-free plain packaging”.
For less motion blur, change the camera move to: “slow dolly-in” or set “fix camera” on.
