Seedance 2.5：如何编写提示词，附带已运行的素材库

LOOK: music video, photoreal, anamorphic widescreen 21:9, fine 35mm film grain, deep crushed blacks, hard contrast, a green-yellow sodium-vapor night grade. SUBJECT: a young man with messy dark curls, a dancer, in a worn brown leather bomber jacket open over a black hoodie, very wide raw denim jeans, a silver chain and clean white trainers. PLACE: an empty underground car park, wet concrete floor, concrete pillars receding into darkness, lit only by a row of sodium-vapor lamps overhead that throw green-yellow pools of light, one flickering fluorescent tube on the far wall, thin haze. FIRST FRAME: he stands center frame in profile under one pool of light, weight on his back foot, head down, the haze drifting past him. ACTION: [0-2s] he snaps his head up to the lens and drops into a low slide to the left, [2-4s] a fast spin that flares the open bomber, [4-5s] he lands in a wide stance facing the lens and holds. CAMERA: low, at knee height, a slow push in through the haze, no cuts. PHYSICS: the leather creases and swings with every move, the hoodie strings fly on the spin, water on the floor splashes under the trainers, the haze rolls where he moves. SOUND: a dry kick drum and a deep sub pulse, trainers squeaking on wet concrete, the low hum of the lamps, no vocals, no melody. No on-screen text, no logos.

ACTION: he explodes out of the pose. [0-2s] a sharp arm whip and a quarter turn toward the lens, [2-4s] a low slide that skims the wet floor, [4-5s] he lands square to camera and holds. CAMERA: low and locked off, no cuts, no new people. PHYSICS: the haze keeps drifting through the green-yellow sodium light, the floor mirrors the lamps, the open bomber flares on the turn. SOUND: trainers squeaking on wet concrete, one deep sub hit on the landing, no music, no vocals. No on-screen text, no logos.

@Video1 is the take. Keep the dancer, his moves, his timing and the camera exactly as they are in @Video1, and keep the soundtrack of @Video1. Recast the place: the same dance now happens on a rooftop helipad at night in light rain, one hard white spotlight from above, the city lights soft in the distance, the wet ground mirroring the light. Vertical 9:16 frame with the dancer centered and room above his head. No cuts, no new people, no on-screen text, no logos.
