Upload your base image plus all storyboard frames into Seedance 2.0 as visual references before generating to guide shot-by-shot continuity.
Use a “Production Sheet” style master prompt that explicitly mandates consistent visual language, lighting, camera behavior, editing rhythm, and proportions across every shot to prevent random changes.
Instruct Seedance to generate one continuous commercial (not isolated clips) and require each new shot to naturally evolve from the previous shot for seamless continuity.
List allowed camera techniques in the prompt (e.g., hero shot, extreme macro, push in/pull out, tracking, orbit/360 orbit, slider, FPV, whip pan, crash zoom) and add “avoid random camera motion” to keep movement motivated.
Add strict “never change” constraints for character identity (face, age, hair, body, skin tone, wardrobe, accessories, expressions, eye direction, proportions) to reduce identity drift across scenes.
Add strict “never change” constraints for product identity (shape, dimensions, color, logo, packaging, material/texture, reflections/gloss, scale) and explicitly “avoid logo distortion/packaging deformation” for brand consistency.
Specify premium ad lighting terms (studio lighting, soft key, hard rim, backlight, volumetric light, specular reflections, cinematic contrast) and require lighting consistency throughout the commercial.
Include a physics realism section (gravity, momentum, inertia; believable splashes/condensation/steam/particles; slow-motion/high-speed debris) to make interactions feel cinematic rather than exaggerated.
Define an editing rhythm in the prompt (rhythmic/momentum editing, invisible cuts, motion/graphic match, object wipes, whip pan transitions, speed ramps, smash cuts) and require each cut to increase engagement.
Add negative constraints like “never introduce random objects,” “avoid inconsistent shadows/reflections,” “avoid unrealistic proportions,” and “prioritize continuity over variety” to reduce artifacts and inconsistencies.
