第一人称过山车直坠地狱

CINEMATIC SETUP: first-person POV | extreme roller coaster | infernal underworld | photoreal horror. Vertical 9:16. One continuous shot, the camera does not cut on its own.

RIDER: Only the rider's hands are seen — worn matte-black leather gloves, the left one torn at a knuckle, gripping a padded steel lap bar with scratched red paint, anchored in the lower third. The front of a black coaster car with dented edges sits just below the hands.

TRACK: A twin-rail steel coaster track with rust-stained cross ties, always visible and centered on the vertical axis, running from the car's nose into the distance in every moment of the shot. It rises, drops, twists and banks, but never leaves the frame.

CAMERA: Chest-mounted POV, FOV 107°, locked to the car. Hard vibration from the rails, sharp jolts at every transition, horizon rolling up to 90° in banked turns and fully inverting in the loop. Speed changes constantly between 15 and 140 km/h. Ends on a colossal creature's face filling the frame.

TIMELINE:
Stage 1: The car crawls at 15 km/h up the last meters of a steep lift hill, chain clanking, the track ahead pointing at an ash-filled sky above a canyon of molten lava. It stops at the crest for one breath: the track below drops vertically into the lava glow. The gloves tighten on the bar. The car tips over and plunges at 140 km/h, the track rushing straight down, snapping level 3 meters above a river of lava. It rockets over three airtime hills in a row, the car lifting off the seat at each crest while pale translucent souls in tattered grey cloth rise from the lava beside the rails, arms reaching up. The track sweeps into a vertical loop: the canyon turns upside down, lava overhead, then the car drops out of the loop into a steep climb. End state: the car crests into a dark tunnel in the canyon wall.
Stage 2: The car shoots out of the tunnel into a cavern of black ice lit cold cyan and drops down a curving slope onto a track running low over the cracked ice floor, figures frozen beneath the surface with hands pressed against the ice flashing under the rails. Massive icicles break from the ceiling and shatter on the rails just ahead; the car blasts through the falling ice shards. The track twists into a corkscrew, the cavern spinning a full 360° around the rails. End state: the car exits the corkscrew through a narrow ice arch.
Stage 3: The car bursts into a forest of giant bone columns arching overhead like ribs and dives into a banked helix, spiraling down at 90° bank. Across the curve of the helix, the track already passed collapses section by section into the darkness below. The track snaps out of the helix into a slalom between the columns. A towering horned skeletal creature, as tall as six humans stacked, swings its long clawed arm down across the track; the car passes beneath the claw and the claw slams into the rails just behind it, sparks flying. End state: the forest opens out onto a plain.
Stage 4: The track races straight across a plain of cracked black rock split by glowing lava seams, then climbs a final hill. At the top, the track ahead is broken by a gap over a glowing lava crack: the car launches over the gap, a full second of airtime above the lava, and slams down onto the rails on the far side with a hard jolt. The ground ahead bursts open and a colossal horned creature of volcanic rock with glowing orange seams, as tall as a twenty-story building, pushes up out of the earth, slams one clawed hand onto the ground beside the rails and leans its face toward the camera, ember eyes glowing. The rail ends right before it and the image fades to black.

PHYSICS: Car mass 600 kg, real centrifugal tilt in every turn, negative g lifting the car at each airtime crest, the gloves tightening at every drop. Heat haze visible at 10 meters over lava. Ash density 30%, ash and embers streaking across the lens. Rock slabs slide off the colossal creature's shoulders as it rises. The creatures never touch the car.

LIGHTING: Lava canyon, bone forest and plain in 2200K orange underlight from molten rock and fire; ice cavern in cold 8500K cyan with no orange light; final moment lit by the creature's glowing seams against dark smoke.

Sound: No score. Production audio only — chain clanking on the lift, a beat of near-silence at the crest, steel wheels screaming on rails, wind roar, lava bubbling, ice shattering, bone striking steel, rails collapsing, ground splitting, deep sub-bass rumble.

QUALITY ANCHOR: Photoreal action-camera footage, slight wide-lens distortion at the edges, fine sensor grain, motion blur on the passing scenery while the track ahead stays sharp. Gloved hands anatomically natural with five fingers, gloves and lap bar consistent throughout. Track continuous and always visible, except for the single gap in stage 4. Consistent lighting per zone, no flicker. One unbroken shot from first frame to fade.
