Promotion vidéo VFX de désastre de tsunami urbain cinématographique

15-second ultra-realistic cinematic urban flood disaster scene, extreme photoreal VFX, giant tsunami wave invading a dense city street, with every visual detail focused on scale, water pressure, structural destruction, weather violence, and catastrophic impact. The tsunami must feel powerful enough to physically break the city apart. Buildings near the wave are not just background - they are struck, damaged, destabilized, and in some cases collapse under the force of the water. 0-3s: The street is already heavily flooded. The camera stays low near the water surface, with dark floodwater surging toward the lens. Floating debris, broken pieces, and dirty foam drift and collide in the foreground. Wind is funneled hard between the skyscrapers, and rain slants sideways through the avenue. In the distance, between the buildings, an enormous tsunami wall begins to rise - a moving ocean cliff, dark blue-gray, with its crest shredded into white spray by the wind. 3-6s: The wave pushes closer and grows even larger in scale. A half-submerged city bus in the midground begins to drift and yaw under the water force. Nearby cars rock, shift, and collide lightly in the flood. Street signs, trash, and loose debris tumble through the current. Human figures in the water look tiny and nearly helpless against the approaching wall of water. Reflections of storm clouds and the wave itself ripple across the glass facades of the skyscrapers, making the entire city feel swallowed by fluid catastrophe. 6-9s: The wave now dominates the whole avenue. Its internal structure must be visible: heavy dark rolling mass, collapsing water pockets, layered white foam belts, torn spray at the crest, and turbulent cross-currents inside the body of the wave. The pressure front of the tsunami begins to alter the floodwater in the street before impact, accelerating the foreground current into chaotic surges, reversals, and colliding surface ripples. The bus is shoved farther sideways by a cross-force of water, while floating objects are pulled into faster moving channels. Lower glass panels and street-level facades begin to crack and burst under the incoming pressure. 9-12s: The giant wave slams fully into the city corridor. The lower sections of nearby buildings are hit directly by the water mass. Glass curtain walls shatter outward in huge sheets, storefront facades are ripped open, concrete cladding tears away, and exposed structural elements appear beneath the skin of the buildings. The tsunami explodes into secondary bursts of white water, dense foam, mist, atomized spray, and shattered water sheets. Lower floors are swallowed by the surge, and some street-facing structures begin to tilt as their bases are undermined. 12-15s: The destruction reaches maximum intensity. One or more buildings near the wave path begin to fail visibly: lower structural sections are smashed through, upper sections lean, fracture, and collapse sideways into the flood corridor. Huge chunks of facade, glass, steel, and concrete crash down into the water and are immediately engulfed by the surge. The leading edge of the tsunami breaks, crashes, and reforms into multiple stacked moving walls of water while the city physically comes apart around it. Foreground floodwater, collapsing buildings, spray bursts, rain, wind, and debris all merge into one overwhelming disaster image. End on the feeling that the tsunami has enough force to erase the street, destroy the architecture, and reduce the city to fragments. VFX priorities: towering tsunami wall, shredded wave crest, exploding white foam, atomized mist, turbulent floodwater, pressure-front acceleration, bus drifting and turning, cars rocking and shifting, glass curtain wall shattering, facade tear-off, exposed structural steel, lower-floor washout, building tilt, progressive collapse, concrete and steel debris falling into floodwater, secondary impact splash walls, compressed urban ocean corridor. Audio: roaring floodwater, deep wave impact, violent wind between buildings, heavy slanting rain, glass exploding, steel groaning, concrete cracking, bus metal strain, cars scraping and knocking in water, debris impacts, foam crash, spray hiss, distant human panic. No music. No subtitles. Negative: no slow motion, no fantasy glow, no cartoon water, no clean dry street, no calm sky, no static buildings, no intact facades after direct wave impact, no empty city, no subtitles.
