Miniature Miami Tsunami BTS

SEEDANCE 2.5 DIRECTOR PROMPT Duration: 15 seconds Aspect ratio: 9:16 Reference: Special effects team = several men wearing black short-sleeved T-shirts (with white "EFFECTS CREW" printed on the back), dark work cargo shorts; consistent styling throughout the entire film            Miniature Miami = hand-built high-precision miniature coastal city model, including wooden amusement pier, white Ferris wheel, artificial beach, miniature palm trees, colorful Art Deco low-rise buildings, and multiple glass-curtain-wall skyscrapers            Wave-making pool = 40-foot giant studio wave pool with deep gray concrete retaining walls, background is a full blue screen with white cross tracking markers            The following body text uniformly uses Chinese names to refer to things, no longer featuring

 numbers. Audio: On-site English shooting instructions and cheers/shouts (lines as per beats within), on-site synchronous sound recording; roaring surge of massive waves, splintering/tearing sounds of wooden structures, violent water impact and overflow sounds, subtle hum of jib motor; no voiceover, no background music, no subtitles Overall style: Hollywood blockbuster behind-the-scenes practical effects documentary (BTS Practical Effects), 9:16 vertical screen, 8K ultra-clear realistic cinematic photography, industrial high-top flood lighting, authentic fluid physics collisions and miniature structure collapses, on-site synchronous shouting, reject CGI feel and game-like plastic sense GLOBAL CONTINUITY Setting: Industrial film special effects giant studio. Center is a 40-foot large rectangular deep concrete wave-making pool with crystal-clear water; behind the pool hangs a full flat blue screen with evenly spaced white cross tracking points; overhead are multiple high-power rectangular soft light banks; foreground concrete platform lays dual-rail camera dolly tracks and heavy-duty camera. Main subject: Miniature Miami in the pool and surging advancing real-physics massive waves as the core destruction subject. Supporting: Special effects team operating multiple heavy film cameras tracking along pool wall rails, cantilever heavy mechanical arm slanting across above the pool. Props: Dolly camera, portable monitor screen, wooden boardwalk debris, snapped-and-fallen miniature palm trees, toppled model skyscrapers smashing into water. Blocking: Foreground bottom is concrete pool edge and camera rails, special effects team with backs to lens or side-standing operating, tight against pool wall; midground is artificial beach, pier, and low-rise street blocks; background is cluster of skyscrapers lined along the pool's rear edge. Lighting: Top high-position industrial soft lights vertically illuminating water surface, forming intense reflective highlights on wave surfaces; blue screen evenly lit without dark corners; no dramatized color filters. Color: 60:30:10 — pool clear blue-green and blue screen deep blue 60% / studio concrete gray and deep dark areas 30% / miniature buildings pink-orange-yellow and white wave spray 10% CAMERA CONTINUITY Entire sequence single lens one-take (One-take High-Angle Tracking). Camera fixed at side-upper high position with wide overhead angle, smoothly advancing forward with slight dive following wave crest push, no cuts, no instant jumps, no jump cuts, no zoom shifts throughout, locked on deep-focus deep-scene focal plane. ACTION ENGINE Action loop must be fixed: Director shouts "Action!" to start waves → azure wave crests build into massive waves → crash shattering wooden pier and Ferris wheel accompanied by on-site shouts → surging white foam sweeps over beach flushing street blocks → water flows over pool edge and director calls tracking commands → massive waves violently slam background skyscraper bases → skyscrapers snap and topple smashing into white waves → special effects team erupts in excited cheers and celebration 0.0–4.0 seconds | Startup wave surge Opening high-position wide overhead. Pool surface calm, foreground cinematographer squats by track checking monitor. Far-end wave-making system activates, pool rear instantly swells into a perfect arc-shaped azure massive wave several feet high, wave crest top curling into white breakers, advancing toward foreground at extreme speed. Lines: Director off-screen in high-volume gravelly shout: "Action!" (opening at 0.5 seconds, sharp abrupt with walkie-talkie static undertone) 4.0–8.0 seconds | Pier destruction Massive wave like a tsunami slams into midground miniature coast. Enormous water wall directly impacts wooden amusement pier, boardwalk instantly smashed into flying debris by water flow, white Ferris wheel twists and topples sinking into torrent under lateral water push, several meters of white foam erupting skyward. Lines: Pool-edge cinematographer staring into viewfinder urgently shouts: "Here comes the swell! Let's go!" (bursts at 5.2 seconds, voice excited and tense) 8.0–11.0 seconds | Flooding street blocks Unstoppable white turbulence sweeps over beach, entire row of miniature palm trees instantly flushed down by torrent; flood peak violently charges into pink and yellow Art Deco street blocks, massive white foam racing through streets at high speed, some water spilling over concrete pool walls toward tracks, cinematographer sidesteps to evade but lens stays locked on pool interior. Lines: On-site supervisor piercing water noise loudly issues commands: "Keep rolling! Camera three, stay on the tower!" (at 8.8 seconds, quick and forceful, hoarse with effort) 11.0–15.0 seconds | Building collapse Climax destruction moment. Surging flood peak directly frontal-impacts rear row of several dozen-story glass-curtain-wall skyscraper models. Under torrent impact, left-side two high-rises' bases snap, entire structures with real physical weight slowly and heavily tilting collapsing sideways forward, directly smashing into white waves kicking up massive water sheet, churning splashes and fine mist instantly enveloping the whole district. Lines: Entire staff erupts in frenzied cheers: "It's going down! Oh my god, it fell! That was perfect!" (from 12.0 seconds to end, with whistles and applause) Environment: Mechanical jib arm above blue screen sweeps uniform arc from left to right, water mist clearly visible under strong lights, pool wall overflow continuously draining. Camera: 0.0–4.0 seconds 24mm high overhead full establishing shot → 4.0–8.0 seconds maintain 24mm slow forward downward push → 8.0–11.0 seconds lens smoothly pans horizontally tracking random position capturing flood → 11.0–15.0 seconds lock on full building collapse view maintaining steady breathing rhythm Constraints:
Water flow physics must be authentic large-scale fluid behavior under real gravity, strictly forbid jelly-like feel or CGI water smooth interpolation; building collapses must show real physical model fracturing, toppling, and water-smash feedback; English on-site lines must strictly sync with action timestamps, with natural reverb and wave-noise masking effects.
Negative: Anime rendering, game CG, cheap green-screen compositing, plastic water bodies, jelly water flows Cartoon lightning, surreal light effects, overdone particle effects, frame distortion Mid-sequence cuts, position instant jumps, third-person aerial shots, violent lens shakes, zoom shifts Buildings vanishing into thin air, models anti-gravity floating, skyscrapers fluttering down like paper Limb distortions, personnel vanishing into thin air, duplicated extra cinematographers Subtitles, screen text, watermarks, brand logos, background music, extra voiceover
