Sora 2 Amateur behind-the-scenes phone video using the EXACT same tiny weathered coastal megacity model, in-floor ~30m water tank, full-size crew, hazard-striped tank lip, colossal five-storey blue chroma-key wall with dense orange tracking crosses, crane/jib and steel dolly-track, and wide framing with the model in the LOWER THIRD. 0–2s ESTABLISH — the huge quiet set holds; tiny model calm, crew waiting, the cavernous room + towering screen dwarfing it. 2–4s TRIGGER — a director calls "Action!" off-camera; practical water-tank machinery and RC boats fire the tsunami. 4–6.5s IMPACT (hero) — the real wave tears across the model, smashing through the miniature coastal structures and erupting many storeys up the towering screen; crew flinch/step back, crane swoops, real spray flies. 6.5–8s AFTERMATH — the surge settles, mist hangs, water sheets off the rim, handheld re-settles, loop-ready. Sound (diegetic only): water-tank machinery hum + RC boats + rising water roar + crew shouts + the director's "Action!" at the trigger + massive water crash arriving WITH the impact + pumps/fans + spray and wind, no music, no narrator. Amateur behind-the-scenes phone photo inside an ENORMOUS cavernous film soundstage the size of an aircraft hangar. A tiny handbuilt MODEL of [THE PLACE — generic, never a real name] sits at model-railway scale on a raised shoreline inside a MASSIVE in-floor water tank sunk flush into the concrete floor (no table, no legs), ~30m across, grey hazard-striped coping and coiled cables round the rim. Towering behind and above: a COLOSSAL BLUE chroma-key wall rising ~5 storeys and running off the top of the frame, covered in many small orange "+" tracking crosses in a dense grid. A massive practical tsunami tears across the model and erupts MANY STOREYS HIGH, spray/dust/ash cresting far up the screen with empty air still above. Full-size crew in black "EFFECTS CREW" and grey "SPECIAL EFFECTS" tees at the tank lip stand as TALL as the model towers, a distant row tiny against the far wall; camera crane/jib + steel dolly-track in shot. Wide phone framing — model in the LOWER THIRD, towering screen + air filling the top two-thirds, nothing fully contained. Flat cool LED wash, sensor grain, mild handheld, auto-exposure clipping the spray — a real phone clip, NOT a render. [DISASTER TAG] Negatives: NOT a tabletop diorama / desk model / model on a table with legs; NOT a cramped small room or low ceiling; NOT the model filling the frame or close tight framing; NOT a short blue screen with its top/side edges in frame; NOT a few large sparse crosses; NOT the whole room contained; no CGI/3D render/game-engine/videogame, no cartoon/anime/illustration, no glossy Octane sheen, no plastic/waxy, no HDR overcook, no fantasy glow, no clean studio-photo look; stays a small MODEL in a huge studio, never the real full-size city; no captions/subtitles/on-screen text, no watermark, no logos, no aspect ratio, no AI tool names.
