Seedance 2.0 剪影人物旋转系绳光源成光涡 电影写实提示词

Scene & Mood: A lone silhouetted figure stands on a dark volcanic rock shelf at the ocean's edge under a dense field of stars, spinning a tethered light source in continuous wide circles to hand paint a glowing amber vortex into the night air primal, meditative, hypnotic.\n\nFrame Map: Wide static composition, 16:9. The figure holds center frame at x=50%, standing on the rock foreground occupying the bottom third. The forming light-circle builds directly around and above the figure through the middle frame. The star field fills the upper two-thirds. The dark ocean stretches as a flat horizontal band across the base, faint white foam catching starlight in the near foreground corners.\n\nSubject Lock: One human figure seen entirely in silhouette against the night sky no visible facial detail, no identifiable features, dark clothing reading as a solid black shape. Feet planted shoulder width apart on the flattest section of the rock shelf, weight low and balanced. One arm extended, rotating in a continuous wide circular motion at the shoulder, swinging a small tethered point-light source around the body in a widening orbit. Head tilted slightly down, tracking the spinning light. Feet stay anchored to the same rock mark for the full runtime only the spinning arm, wrist, and swinging cord move.\n\nCross-Frame Rules: Single subject in frame throughout no other figures, boats, or people enter or cross the shot. Screen position (center, x=50%) and rock contact point never shift.\n\nMovement: The arm completes slow continuous rotations at roughly one revolution every 1.5–2 seconds (0–15s continuous), the tethered light tracing a widening ring of amber-gold trail with each pass, building from a single faint arc at the start to a dense, near-solid glowing halo by the final seconds. Small sparks flick loose from the light source at the outer edge of each rotation, drifting and fading within a second. Fabric shifts subtly with the rotational torque of the swing; loose hair and hems move on a light onshore breeze. Gentle wave-wash rolls in in the near-foreground, small ripples of white foam catching faint ambient light and receding. The star field holds fixed and still throughout no drift on the stars only the light ring intensifies pass over pass.\n\nLast Frame: The full glowing amber circle hangs complete around the figure's silhouette, dense and continuous, stars sharp and undisturbed above, dark rock and faint foam below. No on-screen text, no captions, no signage typography, no rendered text in the frame.\n\nWorld Plate: A remote rocky headland on a tropical island coastline at night, ocean lapping the base of dark volcanic rock, zero light pollution, dense unobstructed star field with the soft band of the Milky Way visible overhead, warm humid air, calm sea state, no artificial light beyond the practical source in the figure's hand.\n\nSound Bed: Steady rhythmic whoosh of the light s
