Start from the output requirements of the campaign, then check the model, duration, aspect ratio, resolution, audio, and export settings available in your account. Prepare clear product images and references you are authorized to use. Prompts should state the subject, action, scene, camera movement, and details that must remain consistent.
Generate a short draft first. Review product proportions, color, logos, text, motion, transitions, and audio. If the interface offers editing or continuation, make a targeted change and inspect the full result again.

Higher pixel resolution does not guarantee that labels, fabric, skin, or movement are accurate. Compare close-ups with the real product, proofread every visible word, and confirm rights for reference media and audio. Check the destination platform's current ad and format requirements before publishing.
