Seedance 2.0 龙卷风摧毁微缩城市 电影写实提示词

Create a photorealistic 15 second cinematic video in 16:9 as one continuous handheld shot inside a vast professional special effects soundstage. Use a natural 24 millimeter wide angle lens at eye level, 24 fps, deep focus, slight operator sway, mild rolling shutter, realistic exposure breathing, and accurate motion blur. The camera begins at the corner of a large rectangular water tank. Blue water fills the lower frame, bordered by concrete, safety cones, and loose production papers. A small red and white model rescue boat floats near center. Above it hangs an enormous ribbed gray fabric funnel suspended from a circular ceiling rig. Green screen walls with tracking markers, black ceiling trusses, bright rectangular studio lamps, yellow wind machines, and a detailed miniature coastal city fill the background. From 0 to 2 seconds, hold the wide composition as the fabric tightens, wrinkles crawl upward, and its narrow tip begins rotating. The movement feels driven by real wind and tension, while reflections tremble across the water. From 2 to 4 seconds, the fabric collapses inward and becomes a dense rotating column of gray mist, dust, and atomized water. The funnel narrows toward the pool and descends with believable turbulent airflow. Drift slightly right while keeping it centered. From 4 to 6 seconds, the vortex strikes the water with a violent white eruption. Concentric waves race outward, the boat pitches and rolls, and heavy spray obscures the far edge. React with a quick controlled pan toward the miniature city. From 6 to 9 seconds, track the tornado across the shoreline. Water surges between buildings, a red vehicle is lifted, windows burst, rooftop objects spin away, and apartment blocks buckle in stages. Every fragment shows weight, collision, drag, gravity, and changing rotational speed. From 9 to 12 seconds, continue panning as miniature towers fold, shear, and fall into the street. A special effects technician appears naturally in the right foreground, wearing a plain black crew shirt and orange hearing protection, bracing against a railing. A tall glass skyscraper remains standing in the left background to provide scale. Keep the tornado dark and volumetric, with layered dust, mist, paper, roof panels, and vehicle parts orbiting at different depths. From 12 to 15 seconds, arc back toward the pool. The vortex returns to the center of the widescreen frame while a broad foamy wave curves around the tank and rushes toward camera. Fine droplets hit the lens, creating soft circular highlights without hiding the action. End with the tornado still spinning over violently churning water. Use harsh overhead studio lighting, cool cyan water reflections, mild green spill, realistic shadows, humid haze, and no stylized color filter. Preserve tiny imperfections, uneven water motion, slight camera shake, lens moisture, and natural debris randomness.
