Vertical 9:16 handheld smartphone video, 15 seconds, one continuous unbroken take, no cuts.
Use the provided image as the exact first frame and visual reference. Preserve the entire film studio, the miniature city, all landmarks, buildings, waterways, boats, camera equipment, crane arm, crew members, blue VFX tracking wall, studio lights, dolly rails, tank walls and camera perspective exactly as shown.
The location is a large indoor film soundstage containing a highly detailed practical miniature of [CITY NAME] inside a large water tank. The miniature must remain recognizably [CITY NAME] throughout the shot. No tropical environment, no beach, no palm trees.
The camera is held from an elevated position behind the crew, looking down toward the miniature city. Authentic behind-the-scenes smartphone footage, slightly imperfect framing, subtle natural handheld movement, realistic phone autofocus and exposure response.
0-2 seconds:
The miniature city and water remain completely still. Crew members quietly wait in position. Reflections from the practical studio lights shimmer slightly on the calm water. An off-screen assistant director calls through the large soundstage with natural room echo:
"And... ACTION!"
2-4 seconds:
A hidden mechanical wave system activates at the far rear side of the water tank behind the miniature city. A heavy pneumatic clunk, metal latch release and deep hydraulic groan are heard. A broad, physically believable swell begins forming across the rear water surface and travels toward the city.
The water must originate from the far side of the tank. It must not appear from the sky, from underneath the buildings or from inside the city.
4-9 seconds:
The wave reaches the outer waterfront and breaks against the miniature quays. Dense miniature-scale whitewater rushes through the canals, streets and harbor basins.
Small boats are pushed from their moorings. Lightweight miniature street props, railings and a few loose facade elements break away naturally. Water flows around [LANDMARK 1] and between the surrounding buildings.
The buildings remain miniature-scale and structurally consistent. No melting architecture, no morphing buildings, no changing city layout and no full-size debris.
Over the rushing water, an off-screen crew member shouts:
"Camera two - stay on [LANDMARK 1]!"
9-13 seconds:
The surge reaches the front edge of the practical water tank and pours over the black tank wall onto the wet studio floor. Water splashes across cables and near the dolly rails.
Crew members react naturally and take several quick steps backward. An off-screen voice shouts:
"Back up! Back up!"
The phone camera drifts slightly to the right and tilts downward just enough to follow the overflowing water, while the miniature city remains visible in the upper part of the frame.
13-15 seconds:
The main surge subsides. Water drains from the miniature streets and harbor edges. Small droplets fall from the tank wall. Loose boats drift slowly. Crew members remain alert while the room fills with draining water, dripping and distant mechanical sounds.
Water physics:
Realistic practical miniature water with small fast droplets, compact foam, visible surface tension, short wave lengths and scale-appropriate splashes. The water must behave like real water filmed around a physical miniature, not like a full-scale ocean tsunami.
Audio:
Live production sound only. Large indoor soundstage reverb. Mechanical release, rushing water, footsteps, boots splashing and distant crew voices. All voices remain off-screen. No visible speaking face, no lip-sync, no narrator, no voiceover and no music.
Camera:
Authentic handheld smartphone recording. Elevated high-angle view. Subtle human shake only. Slight autofocus breathing and natural phone exposure adjustment as the water moves. No cinematic camera orbit, no drone movement, no artificial zoom and no dramatic color grading.
Strict continuity:
Do not add or remove buildings before the wave arrives.
Do not redesign the city.
Do not move or replace [LANDMARK 1].
Do not change the studio layout.
Do not change the camera position abruptly.
Do not transform the miniature into a real full-size city.
Do not introduce tropical vegetation, mountains, beaches or unrelated landmarks.
