Seedance 2.0 微缩泰坦尼克号沉没 纪录片提示词

Behind-the-scenes phone footage from inside a large practical-effects soundstage, shot vertically on a handheld modern smartphone. >> Scene context: a film crew is shooting the sinking of a miniature RMS Titanic. A gigantic practical ocean tank set, dressed as the North Atlantic, contains a 1:24 scale Titanic complete with illuminated portholes, four funnels, lifeboats, deck railings, rigging, cargo cranes, and miniature passengers. Above the tank, a scaffold gantry carries a row of huge dump tanks loaded with practical seawater; two techs stand on the gantry at the release levers. >> First frame: already loaded and ready — the ship and ocean tank fill mid-ground screen-right, dump tanks looming above the set; in the foreground screen-left, within 1 meter of the phone, three crew in black EFFECTS CREW t-shirts stand behind a low containment wall, one on a cinema camera on rails, another on a headset with a hand raised. A huge blue chroma-key wall with orange cross markers rises behind the horizon. A technocrane hangs above the set. >> Action and physics: a shout of “Action!” — the dump tank gates bang open in sequence and a massive surge of real water crashes across the ocean set with real weight and turbulence, the first wave breaking over the bow before racing along the decks, tearing away lifeboats, snapping miniature railings flat, then slamming into the ship: lower decks disappear beneath the waterline, the bow plunging under the surface, the stern rising higher under the hydraulic gimbal, funnels collapsing one after another as the rigging whips, the hull splitting apart at midships before the stern slides beneath the churn; the water bursts over the containment lip and a fine spray cloud rolls across the stage floor, whiting out the frame as the crew shield their faces and stumble back. >> Camera: operator standing then backing away, phone in one hand at chest height, fast handheld pan following the action from bow to stern, framing loose and reactive, hard jolt as the spray cloud hits, autofocus hunting through the whiteout, water droplets clinging to the lens in the final beat, 84° wide diagonal FOV, camera about 2 meters from the containment wall. >> Lighting: overhead LED soft panel grid as primary source, top-front on the camera side, bright daylight-balanced, exposure locked for the reflective water so foreground crew read darker; the spray cloud glows backlit under the panels. >> Audio: on-set ambient — a loud “Action!”, the metallic clang of dump tank gates, the dense roar of cascading water, snapping miniature steel, the groan of the hull breaking apart, crew shouting off-camera: “Hold your marks! Keep rolling! Camera two, stay on the stern!” >> Realistic amateur smartphone capture, natural handheld shake and rolling shutter, real practical effects, documentary behind-the-scenes footage, no cinematic composition, no film grain, no artificial mot
