Prompt library, prompt generator, guides and model breakdowns for ByteDance's Seedance — the model that generates 30-second cinematic video with native audio in a single pass.
Film noir style. A detective in a trench coat runs through a rain-soaked alley at night, hard shadows from neon signs, low-angle tracking shot following his footsteps, wet asphalt reflections, heavy rain, 35mm film grain, high contrast black and white with a single red neon accent, tense orchestral score building. 30 seconds, ends on a close-up of his face as he stops abruptly.

ASMR unboxing loop
Vertical 9:16 social video. Overhead shot of hands unboxing a minimalist product: knife slices tape in one satisfying stroke, tissue paper unfolds crisply, the product lifts out with a soft glow reveal, every sound crisp ASMR quality — tape rip, paper crinkle, gentle thud, loopable ending that matches the opening frame, clean pastel background, no music, sound design only.
