Prompt 2
SEEDANCE 2.0 · 9:16 · 15S · ONE CONTINUOUS HANDHELD TAKE MASTER PROMPT — "Istanbul Bosphorus Tsunami Wave Tank BTS" (15s, vertical 9:16, handheld) ACTIVE REFERENCE Reference 1 is the exact design authority for the miniature set. Recreate its two hero structures at 1:24 scale, preserving proportions, materials and colour exactly: (a) the mid-channel island tower — low white stone curtain wall with crenellations on a rocky islet, an attached red-tiled roof block, a whitewashed half-timbered upper storey with dark timber framing and small dormer windows, a grey lead-covered dome with a small lantern and a green finial, and a tall white flag mast with a red flag; a small red-and-white striped light beacon on the rocks at its left, a low wooden pier with two moored white passenger ferries alongside. (b) the background suspension bridge — twin tall grey steel portal towers, sweeping main cables with vertical hangers, a slim road deck crossing the strait high above the shoreline. Also from Reference 1: the far shore — a domed waterside mosque with two slender minarets sitting under the bridge foot, dense cream, ochre and pale-yellow apartment blocks with red-tiled roofs climbing a green wooded hillside, a long low coastal viaduct running along the waterline, tiny ferries on the water. Use Reference 1 for architecture, colour and layout only — the footage itself is behind-the-scenes studio footage, not a location shot. GLOBAL LOOK Hyper-realistic behind-the-scenes smartphone footage, vertical 9:16, handheld with natural micro-shake, slight rolling-shutter wobble, phone autoexposure — must look like real leaked set footage, no cinematic grade. A colossal film soundstage: an Olympic-sized indoor wave tank filled with deep blue-green water standing in for the strait. The island tower sits on its rock islet in the centre of the tank, close to the near edge; the suspension bridge spans the far half; the mosque, viaduct and hillside townscape line the far bank. Background: enormous bluescreen wall with a grid of red tracking markers; overhead truss with panel lights; a large techno-crane with a stabilized camera head reaching over the tank. In the foreground, effects crew in black "EFFECTS CREW" t-shirts kneel along the concrete tank edge with cinema cameras on dolly track; monitors, tripods and cable runs on the studio floor. SHOT 1 (00:00–00:03) — Calm strait, tower reveal EFFECT: handheld observational hold + slow drift Elevated operator's POV over the crew's shoulders: flat calm water, the island tower and its red flag mirrored in it, the moored ferries idle at the pier, the bridge and minarets small behind, dolly rails in foreground, crew silhouettes against the bluescreen Phone exposure balancing bright water vs dark rigging Continuous take — the entire video is ONE unbroken handheld shot SHOT 2 (00:03–00:05) — Wave generation EFFECT: practical swell formation + slow camera tilt A massive smooth swell rises across the full width of the tank at the far end and rolls down the strait toward the bridge, glassy face catching the studio lights, already taller than the bridge deck The far-shore mosque disappears behind the rising face; crew lean into their eyepieces; handheld drift follows the swell SHOT 3 (00:05–00:08) — The bridge goes EFFECT: miniature-scale breaking wave + span collapse The wave breaks against the bridge: whitewater climbs both grey towers, the deck is buried, main cables snap on the near tower with a whipping recoil, and a whole deck section tears free and folds into the churn in slow heavy miniature physics, tiny cars spilling off it The surge shears the coastal viaduct off its piers and rips the mosque's near minaret away at its base Camera pans down-frame tracking the front as it closes on the tower SHOT 4 (00:08–00:12) — The tower falls, crew scramble EFFECT: hero miniature collapse + water breaching the tank wall The wall of foam slams the islet: the moored ferries are lifted and thrown over the pier, the light beacon snaps off its rock, water bursts through the crenellated stone wall and the red-tiled block is stripped away The half-timbered storey shudders, the lead dome tips, and the whole upper structure leans and topples sideways into the churn, the flag mast whipping down last — heavy, slow miniature physics Water crests the concrete tank edge and cascades onto the studio floor; crew grab gear and stumble backward off the dolly track. Handheld shake intensifies, quick reframes between the drowning tower and the fleeing crew. This is the SIGNATURE VISUAL EFFECT: the icon coming down practically, in-camera, in a studio tank SHOT 5 (00:12–00:15) — Overflow aftermath EFFECT: waterfall over tank edge + wide destruction tableau Sheets of water pour over the tank wall; in the foam float the lead dome with its green finial, the red flag still on its snapped mast, capsized white ferries, roof tiles and the twisted bridge deck; the bare stone islet wall stands broken above the churn, the crane arm silhouetted above Crew stand ankle-deep on the flooded floor, still filming; spray droplets visible on the phone lens Ends on this wide hold — no fade, hard stop MASTER EFFECTS INVENTORY Continuous handheld one-take (whole video) — micro-shake, imperfect reframes Practical wave-tank swell and break (shots 2–3) Suspension bridge collapse (shot 3) — cable snap, deck tear and fold Viaduct shear + minaret snap (shot 3) — background destruction layer Island tower collapse (shot 4) — wall breach, dome tip, sideways topple, flag mast last Ferry toss + beacon snap (shot 4) — small-scale impact beats Water breaching containment (shots 4–5) — cascades onto real studio floor Floating debris tableau (shot 5) — dome, flag, ferries, twisted deck Lens droplets + exposure shifts (shots 1, 5) — realism cues EFFECTS DENSITY MAP 00:00–00:05 = LOW (calm hold, swell rise — 2 effects) 00:05–00:12 = HIGH (wave break, bridge collapse, viaduct and minaret, tower fall, wall breach, crew scramble — 6 stacked) 00:12–00:15 = MEDIUM (overflow waterfall, debris tableau — 2 effects) ENERGY ARC Act 1 (0–5s): mirrored calm — tower, flag, ferries on still water; sells the "real shoot" premise Act 2 (5–12s): the wave takes the bridge, then the tower, then breaks the fourth wall by breaching the tank Act 3 (12–15s): flooded-floor aftermath, the red flag drifting past — hard stop AUDIO: raw on-set production audio only, no music — a loud "Action!", the hydraulic thump of the dump tank, a building roar of moving water, snapping scale cables, groaning steel, cracking timber miniatures, water slapping the stage floor, crew shouting off camera "Hold on! Keep rolling! Camera two, stay on the tower!" Negative prompt: no CGI-looking water, no color grading, no lens flares, no smooth gimbal motion, no cuts, no text overlays, no watermarks, no logos, no distorted hands or faces, no ocean horizon, no drone or aerial angle — the bluescreen and studio must stay visible; do not change the tower's proportions, dome shape or flag.

Prompt 1
GPT IMAGE 2 · VERTICAL 9:16 · TEXT-TO-IMAGE, NO REFERENCES Photorealistic behind-the-scenes still from inside a vast practical-effects soundstage, shot on a handheld modern smartphone, vertical 9:16, natural ungraded phone colour, sharp modern sensor detail. A colossal indoor water tank fills the frame, dark blue-green water at rest. Built into it is a hyper-detailed 1:24 scale miniature of the Istanbul Bosphorus: the strait running diagonally into the background between two miniature shorelines. On the near European shore, dense rows of tiny pastel and timber waterfront mansions with red tile roofs step up a steep miniature hillside packed with apartment blocks; a domed Ottoman mosque with two slender minarets sits at the water's edge beside a small stone quay. A miniature stone fortress with round towers and crenellated walls climbs the hill behind it. Spanning the strait in the mid-ground, a suspension bridge with two tall steel towers and fine cable arrays crosses to the far Asian shore, where more miniature rooftops, minarets and a small ferry terminal run into the background. Half a dozen tiny passenger ferries and fishing boats sit on the water on hidden underwater rails. Studio reality stays fully visible: an enormous blue chroma-key wall with orange cross tracking markers rises behind the whole set, an overhead truss grid with large LED soft panels, a technocrane arm reaching over the tank, a cinema camera on dolly track along the near tank edge, cable runs, monitors, flight cases, and three crew in black EFFECTS CREW t-shirts and rubber boots standing at the concrete tank lip in the near foreground, dwarfing the miniature city. Lighting: overhead LED soft panel grid as primary source, bright daylight-balanced, top-front on the camera side, exposure locked for the water so the foreground crew read slightly darker; soft speculars across the still surface, clean reflections of the miniature skyline in the water. 84 degree wide phone lens character, camera 2 metres from the tank edge at chest height, straight architectural lines rectilinear, no fisheye curve, deep focus so tiny windows and roof tiles stay readable. No captions, no on-screen text, no watermarks, no logos, no CGI look, no colour grading, no lens flares, no real ocean horizon — the bluescreen and studio must stay visible.

The Miniature Apocalypse
Faking a leaked wave-tank disaster shoot — GPT Image 2 builds a 1:24 scale Bosphorus inside a soundstage, then Seedance 2.0 sends the wave through it.
A TUTORIAL BY DENIZ AKKABAK · @DENIZ.AKKABAK
PIPELINE GPT IMAGE 2 → SEEDANCE 2.0 FORMAT 9:16 · 15S · ONE TAKE GENRE FAKE BTS DISASTER
This video lies twice, beautifully. It pretends to be leaked behind-the-scenes footage from a practical-effects shoot — and the shoot itself is pretend: a miniature Istanbul in an Olympic-sized wave tank, bluescreen and tracking markers in plain view, a crew scrambling when the water breaches the tank. The realism comes from embracing the studio instead of hiding it. The pipeline is two generations: a single still image that acts as the world bible, then one master prompt that floods it.
THE PIPELINE AT A GLANCE
- 01
Build the set
GPT Image 2 generates the BTS still from text alone — the miniature Bosphorus, the tank, the bluescreen, the crew. This image becomes the design authority for everything that follows.
- 02
Roll the wave
Seedance 2.0 takes that still as Reference 1 and executes a shot-by-shot master prompt: swell, bridge collapse, tower fall, tank breach, flooded-floor aftermath — one unbroken handheld take.
STEP 01
GPT Image 2 — Building the World Bible
No reference image goes in here — the entire set is written. The prompt reads like a production designer's brief: the 1:24 miniature city and its landmarks, the studio machinery around it (bluescreen, truss grid, technocrane, dolly track), the lighting plan, and even the phone-lens optics. Generate in vertical 9:16 so the still matches the video frame it will later govern. Every detail you lock here — roof colours, the mosque, the bridge, the crew shirts — is a detail Seedance will be ordered to preserve.

Seedance 2.0 — Flooding It in One Take
Switch to Seedance 2.0, set 9:16 and 15 seconds, and attach the Step 01 still as the only reference. The master prompt below is built like a real VFX breakdown document — an active-reference clause that appoints the still as design authority, a global look, five timed shots each carrying its own EFFECT line, then an effects inventory, a density map, an energy arc, raw production audio, and a negative prompt. It is long on purpose: this is a production document the model executes, not a wish.
REFERENCE INPUT
Prompt 2
SEEDANCE 2.0 · 9:16 · 15S · ONE CONTINUOUS HANDHELD TAKE MASTER PROMPT — "Istanbul Bosphorus Tsunami Wave Tank BTS" (15s, vertical 9:16, handheld) ACTIVE REFERENCE Reference 1 is the exact design authority for the miniature set. Recreate its two hero structures at 1:24 scale, preserving proportions, materials and colour exactly: (a) the mid-channel island tower — low white stone curtain wall with crenellations on a rocky islet, an attached red-tiled roof block, a whitewashed half-timbered upper storey with dark timber framing and small dormer windows, a grey lead-covered dome with a small lantern and a green finial, and a tall white flag mast with a red flag; a small red-and-white striped light beacon on the rocks at its left, a low wooden pier with two moored white passenger ferries alongside. (b) the background suspension bridge — twin tall grey steel portal towers, sweeping main cables with vertical hangers, a slim road deck crossing the strait high above the shoreline. Also from Reference 1: the far shore — a domed waterside mosque with two slender minarets sitting under the bridge foot, dense cream, ochre and pale-yellow apartment blocks with red-tiled roofs climbing a green wooded hillside, a long low coastal viaduct running along the waterline, tiny ferries on the water. Use Reference 1 for architecture, colour and layout only — the footage itself is behind-the-scenes studio footage, not a location shot. GLOBAL LOOK Hyper-realistic behind-the-scenes smartphone footage, vertical 9:16, handheld with natural micro-shake, slight rolling-shutter wobble, phone autoexposure — must look like real leaked set footage, no cinematic grade. A colossal film soundstage: an Olympic-sized indoor wave tank filled with deep blue-green water standing in for the strait. The island tower sits on its rock islet in the centre of the tank, close to the near edge; the suspension bridge spans the far half; the mosque, viaduct and hillside townscape line the far bank. Background: enormous bluescreen wall with a grid of red tracking markers; overhead truss with panel lights; a large techno-crane with a stabilized camera head reaching over the tank. In the foreground, effects crew in black "EFFECTS CREW" t-shirts kneel along the concrete tank edge with cinema cameras on dolly track; monitors, tripods and cable runs on the studio floor. SHOT 1 (00:00–00:03) — Calm strait, tower reveal
handheld observational hold + slow drift Elevated operator's POV over the crew's shoulders: flat calm water, the island tower and its red flag mirrored in it, the moored ferries idle at the pier, the bridge and minarets small behind, dolly rails in foreground, crew silhouettes against the bluescreen Phone exposure balancing bright water vs dark rigging Continuous take — the entire video is ONE unbroken handheld shot SHOT 2 (00:03–00:05) — Wave generation
practical swell formation + slow camera tilt A massive smooth swell rises across the full width of the tank at the far end and rolls down the strait toward the bridge, glassy face catching the studio lights, already taller than the bridge deck The far-shore mosque disappears behind the rising face; crew lean into their eyepieces; handheld drift follows the swell SHOT 3 (00:05–00:08) — The bridge goes
miniature-scale breaking wave + span collapse The wave breaks against the bridge: whitewater climbs both grey towers, the deck is buried, main cables snap on the near tower with a whipping recoil, and a whole deck section tears free and folds into the churn in slow heavy miniature physics, tiny cars spilling off it The surge shears the coastal viaduct off its piers and rips the mosque's near minaret away at its base Camera pans down-frame tracking the front as it closes on the tower SHOT 4 (00:08–00:12) — The tower falls, crew scramble
hero miniature collapse + water breaching the tank wall The wall of foam slams the islet: the moored ferries are lifted and thrown over the pier, the light beacon snaps off its rock, water bursts through the crenellated stone wall and the red-tiled block is stripped away The half-timbered storey shudders, the lead dome tips, and the whole upper structure leans and topples sideways into the churn, the flag mast whipping down last — heavy, slow miniature physics Water crests the concrete tank edge and cascades onto the studio floor; crew grab gear and stumble backward off the dolly track. Handheld shake intensifies, quick reframes between the drowning tower and the fleeing crew. This is the SIGNATURE VISUAL EFFECT: the icon coming down practically, in-camera, in a studio tank SHOT 5 (00:12–00:15) — Overflow aftermath
waterfall over tank edge + wide destruction tableau Sheets of water pour over the tank wall; in the foam float the lead dome with its green finial, the red flag still on its snapped mast, capsized white ferries, roof tiles and the twisted bridge deck; the bare stone islet wall stands broken above the churn, the crane arm silhouetted above Crew stand ankle-deep on the flooded floor, still filming; spray droplets visible on the phone lens Ends on this wide hold — no fade, hard stop MASTER EFFECTS INVENTORY Continuous handheld one-take (whole video) — micro-shake, imperfect reframes Practical wave-tank swell and break (shots 2–3) Suspension bridge collapse (shot 3) — cable snap, deck tear and fold Viaduct shear + minaret snap (shot 3) — background destruction layer Island tower collapse (shot 4) — wall breach, dome tip, sideways topple, flag mast last Ferry toss + beacon snap (shot 4) — small-scale impact beats Water breaching containment (shots 4–5) — cascades onto real studio floor Floating debris tableau (shot 5) — dome, flag, ferries, twisted deck Lens droplets + exposure shifts (shots 1, 5) — realism cues EFFECTS DENSITY MAP 00:00–00:05 = LOW (calm hold, swell rise — 2 effects) 00:05–00:12 = HIGH (wave break, bridge collapse, viaduct and minaret, tower fall, wall breach, crew scramble — 6 stacked) 00:12–00:15 = MEDIUM (overflow waterfall, debris tableau — 2 effects) ENERGY ARC Act 1 (0–5s): mirrored calm — tower, flag, ferries on still water; sells the "real shoot" premise Act 2 (5–12s): the wave takes the bridge, then the tower, then breaks the fourth wall by breaching the tank Act 3 (12–15s): flooded-floor aftermath, the red flag drifting past — hard stop
raw on-set production audio only, no music — a loud "Action!", the hydraulic thump of the dump tank, a building roar of moving water, snapping scale cables, groaning steel, cracking timber miniatures, water slapping the stage floor, crew shouting off camera "Hold on! Keep rolling! Camera two, stay on the tower!" Negative prompt: no CGI-looking water, no color grading, no lens flares, no smooth gimbal motion, no cuts, no text overlays, no watermarks, no logos, no distorted hands or faces, no ocean horizon, no drone or aerial angle — the bluescreen and studio must stay visible; do not change the tower's proportions, dome shape or flag.
STEP 03
Anatomy — Why the Master Prompt Works
- 1
Design authority
The ACTIVE REFERENCE block doesn't just say “use this image” — it appoints the still as the exact authority for two hero structures, itemising walls, dome, finial and flag so the model cannot redesign the landmark mid-collapse.
- 2
Leaked, not graded
GLOBAL LOOK bans everything cinematic — no grade, no gimbal, phone autoexposure, rolling-shutter wobble. Imperfection is the realism engine; the bluescreen staying visible is what sells the “real shoot” lie.
- 3
Shots with EFFECT lines
Each of the five shots names its practical effect like a VFX breakdown sheet. Seedance choreographs far better when every window of time owns one clearly named mechanical event.
- 4
The fourth-wall beat
Shot 4 is the signature: the wave doesn't just destroy the miniature, it breaches the tank and attacks the studio itself. Escalating from diegetic destruction to set destruction is the share-trigger.
- 5
Inventory + density map
The MASTER EFFECTS INVENTORY and DENSITY MAP restate every effect and pace them LOW → HIGH → MEDIUM. Redundancy is deliberate — rules stated twice are rules obeyed.
- 6
Sound as proof
The audio is all production reality: “Action!”, the dump-tank thump, snapping scale cables, crew shouting to keep rolling. No music means no fiction — the ear believes before the eye does.
- 7
The insurance
The negative prompt kills the failure modes one by one: CGI-looking water, smooth motion, ocean horizons, aerial angles — and freezes the tower's proportions, dome and flag so the hero miniature survives until the script says otherwise.
THE RESULT
Output — One Take, One Drowned Miniature
Measure it against the density map: two quiet effects before 00:05, six stacked between 00:05 and 00:12, and the overflow tableau to close — with the red flag drifting past the lens exactly as scripted. When a prompt is written like a production document, the model shoots the production.
BUILD THE WORLD. THEN DROWN IT.
The best fake footage is a documentary of a fake shoot.
Swap the Bosphorus for any skyline you can describe: still-image world bible first, master-prompt shoot second. The two-step pipeline — and the leaked-BTS framing — carries any miniature disaster you can dream up.
