ZEPHYR — SEEDANCE 2.0 PROMPT
SCENE: "Cliffhang — a hint of the bridge cracking" — UNDER THE BRIDGE, lens UP, a bit further + mild edge distortion (pebbles fall + dust settles on lens) · NO robot · 1 shot · ~8s · 4K
BRIEF: camera literally on the ground under the bridge, aimed straight UP; the bridge lightly cracks and a few pebbles / crumbs drift down — just a HINT of collapse, NOT grandiose destruction. (No mech in this version.)

Reference binding (load in this order):
<<<image_1>>> → @bridge_from_below (hanging_location_ref_4_2 — low from the riverbed looking UP at the broken span; THE composition/vantage) · <<<image_2>>> → @broken_bridge (the broken span / torn edge detail — Broken_Bridge_2 / anchor)
CAMERA — UNDER THE BRIDGE, LENS UP, A BIT FURTHER (locked — IMPORTANT): the camera is on the ground under the broken span, lens pointing UP, but pulled back a bit — NOT jammed against the underside. Medium distance: the underside + the torn break read clearly overhead, filling much of the frame but with some pale foggy sky around the edges (breathing room). Still directly under, looking up — NOT a far / wide / general establishing shot, NO horizon, NO skyline band, NO side view of the whole bridge.
LENS (locked): wide-angle with a MILD BARREL DISTORTION at the edges — straight lines (beams, girders) gently bow outward near the frame edges, an immersive slightly-distorted under-the-bridge look. NOT extreme fisheye, no heavy warp — just a soft edge curve.
HINT ONLY — NOT GRANDIOSE (locked): only a subtle hint of failure — hairline cracks, dust/grit, a steady sprinkle of small pebbles. NO big collapse, NO large sections tearing, NO heavy debris, NO total destruction — restrained, small.
PEBBLES + DUST ON LENS (locked — key beat): a steady sprinkle of crumbs and small pebbles falls DOWN from the underside toward the camera (enough of them — a real trickle), real gravity + motion blur, some passing / tapping the lens. Then fine DUST drifts down and SETTLES ON THE LENS — a light dusty veil + speckles accumulating on the glass, softening + dimming the image toward the end.
GRADE / COLOR UNIFY + INTEGRATION (locked): references are intentionally desaturated — balance ALL into ONE cohesive grade (matched WB, exposure, contrast, saturation, grain): cold desaturated blue-grey base + earthy rust accents. Debris filmed in the same fog/light — not pasted/composited.
ONE BRIDGE ONLY (locked): exactly ONE bridge — the same @bridge_from_below/@broken_bridge; never spawn a new/second/different bridge.
NO MECH (this version): no robot / no mech / no cable in frame — just the bridge and the falling debris.
NO UI / NO TEXT (locked): no HUD, screen/visor frame, gauges, on-screen text/numbers/Chinese or Korean characters, logos, watermarks.

STYLE PREFIX
Style: 4K, photorealistic, real film grain + halation, large-format/IMAX-grade. NOT 3D render, NOT game engine, NOT cartoon.
Operating style — HOYTE VAN HOYTEMA: in-camera realism, atmospheric fog + volumetric light, tactile dust, vertiginous up-angle, photochemical, quiet dread (restrained).
Lighting: flat overcast daylight through heavy fog, soft sky key from above, cold desaturated earthy colour, gentle roll-off.
Color — ACCENT DOCTRINE: ~75% cold blue-grey (fog, concrete, sky) + ~25% rust-red (corroded steel) counter-note. (See GRADE-UNIFY.)
Texture: corroded steel, spalled concrete, exposed rebar, fine falling dust + small grit/pebbles, fog moisture; 65mm grain, no digital sheen.
Camera/Lens: large-format 65mm spherical prime, 180° shutter natural motion blur, creamy falloff, natural halation; subtle lens breathing. No anamorphic streaks, no flares.
Physics: real gravity + mass — concrete hairline-cracks, a little dust lets go, small pebbles fall toward the low camera with real acceleration + motion blur; nothing floats; fog drifts. Restrained scale.
Continuity: ONE bridge; structure, fog, light + colour temp consistent the whole take.
Technical: 4K, real-time 24fps (no slow-motion), no flicker/warp/morph.
Audio: environmental SFX only. No music, no subtitles, no on-screen text, no watermarks.

ASSETS
<<<image_1>>> = @bridge_from_below — low from the dried riverbed looking UP at the underside of the broken span; debris field + fogged ruined city; the from-below vantage.
<<<image_2>>> = @broken_bridge — the torn collapsed span / broken edge, corroded rust-red steel + spalled concrete + bent rebar; cold foggy daylight.

SHOT — FROM DIRECTLY UNDER THE BRIDGE, lens straight UP (~8s): underside overhead, pebbles sprinkle down, dust settles on the lens
SCENE CONTEXT The camera is on the ground under the broken span, lens pointing UP, pulled back a bit (medium distance — not jammed against it) (<<<image_1>>>/<<<image_2>>>). The underside — beams, girders, spalled concrete, the torn break — reads clearly overhead, filling much of the frame with some pale foggy sky around the edges; straight lines gently bow at the edges (mild barrel distortion). The structure gives a quiet groan; hairline cracks spider and a steady sprinkle of crumbs + small pebbles falls DOWN toward the lens (enough of them), some tapping the glass. Then fine dust drifts down and SETTLES ON THE LENS — a dusty veil building on the glass, softening + dimming the frame. Just a hint — no big collapse. NO words.
ACTIVE REFERENCES <<<image_1>>> (under / up vantage) 100%; <<<image_2>>> (broken underside) 100%.
LOCATION MAP Camera on the ground under the span, aimed UP, a bit back; the broken underside + break fill much of the frame overhead with pale sky around the edges; mild barrel bow at the edges; a steady sprinkle of falling pebbles + dust toward the lens. NO horizon, NO skyline band, NO wide side view, NOT jammed against the bridge.
OPTICS / CAMERA Under, looking up, medium distance (pulled back a bit, not jammed). Wide-angle lens with MILD BARREL DISTORTION at the edges (gentle outward bow of the beams near the frame edges; not fisheye). Near-static with a faint tremor; falling pebbles in the foreground with real motion blur; dust progressively settling on the lens (soft dusty layer + speckles by the end). Subtle lens breathing. SAME bridge stays consistent.
ACTION TIMING 0–2s: under the span, lens up, the broken underside overhead, a quiet groan, hairline cracks appear. 2–5s: a steady sprinkle of pebbles + grit falls down toward the lens (enough of them), some tapping the glass; faint tremor. 5–8s: the pebbles ease and fine DUST drifts down and SETTLES on the lens — a dusty veil + speckles build on the glass, the image softening + dimming; end on the dust-covered lens. (No large collapse.)
PHYSICS Concrete hairline-cracks + sheds dust; a steady sprinkle of small pebbles falls toward the low camera with real gravity + motion blur; then fine dust drifts and accumulates on the lens glass (settling, not floating); heavy mass, nothing floats unnaturally; fog drifts.
LIGHTING Flat overcast through heavy fog, soft pale light in the gaps overhead; cold ambient; dust catching the light; faint rust glints on the underside steel. Haze, grain. Dust + debris integrated in the same fog (not pasted); the settling dust slightly diffuses the image at the end.
COLOUR ~75% cold blue-grey (concrete underside + sky slivers); ~25% rust-red (steel). GRADE-UNIFY to one look.
AUDIO A quiet structural groan, soft concrete crackle, a steady trickle of grit, pebbles ticking down + tapping the lens, a soft dusty hiss as it settles, distant city echo. NO words. SFX only. No music.
LOCKS UNDER THE BRIDGE, lens UP, a bit further (medium distance, NOT jammed against the underside); underside + break read clearly with some sky at the edges; wide-angle MILD BARREL distortion at the edges (gentle bow, not fisheye); NOT a wide / general / distant / side shot, NO horizon/skyline; HINT only — hairline cracks + a steady sprinkle of pebbles toward the lens (enough), NO big collapse / large debris; then fine DUST SETTLES on the lens (dusty veil + speckles, softening/dimming); faint tremor, near-static; NO mech / no cable; ONE bridge (no new structure); GRADE-UNIFY + integration; real gravity on debris; NO UI/HUD/text; non-verbal; 4K 24fps; SFX only; no music; markers never generated.
