3×3 storyboard grid → Seedance for 2× better video output

Before firing a 15s Seedance prompt, draft a 3×3 grid in Figma or any canvas app. Nine frames representing the 9 beats of your clip (shots 1-9, one per second-ish). Attach that grid as image_input to Seedance alongside your text prompt. Seedance follows the visual beat map way more tightly than it follows pure prose. Hit rate jumps roughly 2× on first-take quality — it's the single biggest improvement you can make to video generation without changing models.
