上班族躺在床上进地铁 · 闭着眼刷卡过闸
15 秒荒诞写实短片，怎么做出来的？

PROMPT HEADER:
Generate a 15-second horizontal 16:9 photorealistic live-action comedy video at 30 fps. Use Reference Video only as a broad motion, camera, pacing, and live-action realism reference. Create one flowing, uninterrupted low-camera tracking shot with no cuts. The comedy should read immediately: an exhausted office worker has brought his entire bed on his morning commute, yet he still pays the subway fare in the ordinary way.
LOCATION AND WORLD:
Use one spacious, plausible New York-style subway concourse and one wide automatic accessible fare lane. The station has off-white glazed tile walls, gray floor tiles with visible seams, brushed stainless-steel gate housings, a few dark-red structural columns, overhead fluorescent panels, yellow tactile paving, and restrained overhead route signs written in English. Keep the station practical and believable, with natural morning crowd movement and no readable branding.
The electronic reader is integrated into the right-hand steel gate housing at the entering end of the lane. It has a small green-lit contactless surface above the man's mattress level, a visible metal body continuing down to the floor, and an automatic gate panel connected to the housing. The reader must look physically mounted to the gate, not like a floating screen.
PROTAGONIST AND WARDROBE:
Show exactly one American male office worker, about forty years old, with short dark-brown hair, a natural slightly tired face, and faint morning stubble. He wears a white button-down work shirt with a loosened navy tie, visible at the neck and shoulders above the duvet.
He lies on his left side throughout the entire shot, with his head on a white pillow, torso and legs beneath a thick rumpled cool-gray duvet. His expression begins with heavy eyelids and a weary crease between his brows. His cheek compresses the pillow. He never needs to lift his head to complete the commute. He carries one small contactless fare card beside his pillow, flat in the fingers of the hand nearest the gate.
BED AND PROPS:
The bed is one compact American single bed with a simple pale-oak rectangular frame, a low slatted headboard at the pillow end, four small swiveling caster wheels, a fitted gray sheet, one gray mattress supported completely by the wood frame, one white pillow, and one gray duvet. The wheels touch the tiles and rotate as the bed rolls at a gentle walking pace.
A closed black leather work briefcase with a short handle lies flat on the upper surface of the duvet near the foot. In the opening side composition, the foot and briefcase appear screen-left, while the man's face, pillow, and approaching fare reader appear screen-right.
COMMUTERS:
The crowd comprises adult American commuters of varied backgrounds wearing contemporary Western work clothes: navy and charcoal suits, office shirts, business-casual jackets, practical coats, leather shoes, backpacks, shoulder bags, and occasional briefcases. They walk at an ordinary brisk morning pace through adjacent fare lanes and across the distant concourse. A few closer passersby may briefly cross the edges of the shot and partially mask the bed without becoming subjects. Do not introduce a second version of the protagonist.
CONTINUOUS SHOT PLAN:
0.0-2.7 seconds — Opening side track:
Start already moving at low mattress height on the visible side of the bed, roughly a three-quarter side angle. Keep the whole wooden bed in frame, from its near foot and front caster at screen-left to the pillow and the man's face at screen-right. Office workers stride toward the fare gates beneath English wayfinding signs in the background. The camera tracks alongside at almost the same pace as the bed, so the bed holds a fairly stable place in frame while the tiled floor, commuters, and station equipment slide past. The man's face is half visible, his eyes heavy and his mouth relaxed, with his cheek still on the pillow.
2.7-5.5 seconds — Advance toward the reader:
Continue the same tracking move and gradually advance the camera toward the head of the moving bed. Change organically from the complete bed in a low wide side view to a tighter side medium shot of the man's upper body, white pillow, near edge of the gray mattress, and approaching gate. The green reader, a restrained orange or dark accent on the metal housing, and the gate panel grow larger at screen-right as the pillow comes alongside them. Keep enough of the steel housing visible to show that the reader is part of the station gate and firmly planted on the floor.
The man gives a faint squint and a tiny sleepy frown as he senses the reader beside him. Near 5.2 seconds, his hand rests beside the pillow holding the card, ready to move.
5.5-6.7 seconds — Prepare the tap:
Settle into a close side composition that keeps four elements together: the man's face, the white pillow, his card hand, and the green reader set into the upright steel gate. His eyelids crack open just enough to aim; his eyebrows draw together slightly, then relax. He extends the hand resting near the pillow, keeping his elbow and forearm low over the mattress. His wrist lifts only a little, bringing the small card toward the reader at screen-right. His cheek remains on the pillow and his body stays curled beneath the duvet. The camera matches the bed's forward movement and inches closer to the card and reader without losing the face or the vertical metal post.
6.7-7.4 seconds — Single decisive payment:
Show one clear fare payment. The card touches the green-lit contactless surface on the gate housing and holds there for a short beat. The reader brightens in confirmation, and the gate panel opens to give the approaching bed a clear passage. Keep the close framing wide enough to read the entire causal chain in one view: card in hand, contact with a mounted reader, reader response, gate opening, and the man's face still pressed into the pillow.
7.4-8.7 seconds — Return to sleep:
Continue past the reader in the same flowing shot. The man bends his elbow, brings the card back to the mattress near his pillow, and relaxes his hand under the gray duvet. His eyelids settle shut, the small crease in his brow smooths out, and his mouth returns to a slack sleepy expression. The camera glides with the bed, allowing the reader to leave the close composition while the metal gate body remains briefly visible beside and behind him.
8.7-10.5 seconds — Reveal the bed again:
Widen gradually as the camera shifts backward alongside the rolling bed. Show more of the gray duvet, pale-oak side rail, front and rear casters, and the black briefcase reentering the frame toward the foot. The steel gate reader is now behind the pillow end; its changed position clearly shows that the bed has passed the payment point. The bed keeps a steady heading through the open passage while commuters continue through their own lanes at faster speed.
10.5-12.8 seconds — Arc around the foot:
Let the moving camera arc gently around the foot of the bed while still following its travel. Change from the side-rear angle into a low, nearly centered view directly behind the footboard. Frame the two fixed steel gate housings as vertical borders to the lane, one on each side of the bed. The head and front casters lead through first, followed visibly by the side rails, the footboard, the briefcase above it, and finally the rear casters. Follow far enough to show the entire wooden frame and all wheels clearing the passage.
12.8-15.0 seconds — Final trailing view:
Settle behind the bed in a more symmetrical, slightly wider trailing view. The gate housings slide behind the camera's field of view as the complete bed rolls out into the station hall. Center the bed and let it gradually appear smaller as it travels farther ahead, with the black briefcase still lying on the duvet. Follow gently at a slower pace than the bed, opening up the space around it for the final image.
VISUAL AND MOTION RULES:
Photorealistic live-action subway comedy, natural overhead station lighting, restrained gray-blue morning colors, subtle reflections on brushed metal, realistic tile and wood materials, and clean detail on the man's face and card during payment. Use realistic motion blur only on passing commuters. Maintain one continuous physical space and one uninterrupted camera move. The bed must remain a single coherent object, all four wheels must stay attached, and the man's body, wardrobe, pillow, duvet, briefcase, and card must remain consistent.
No cuts, hidden transitions, sudden camera jumps, teleportation, impossible bed movement, floating reader, detached gate parts, or unexplained changes in the station layout. The bed should move through the gate in the same direction established at the beginning, and the payment must happen before the bed passes the reader.
AUDIO:
Generate authentic synchronized subway ambience only: shoe steps, faint rolling casters, distant station hum, subtle fabric and mattress movement, the automatic gate mechanism, and one single soft contactless confirmation beep. No spoken lines, no narration, no subtitles, no lyrics, and no music bed.
NEGATIVE PROMPT:
Cuts, montage editing, hidden cuts, camera teleportation, discontinuous tracking shot, impossible camera path, floating fare reader, detached gate housing, missing gate panel, extra fare readers, broken gate geometry, bed levitating, bed sliding without wheel rotation, missing caster, extra caster, warped wood frame, changing mattress, changing duvet, duplicate briefcase, missing briefcase, extra beds, extra protagonist, duplicate man, face drift, changed hair, changed shirt, tightened tie, standing man, sitting man, man lifting his head, man changing sides, card disappearing, card failing to touch reader, gate opening before payment, payment without mounted reader, hand deformation, extra fingers, extra limbs, broken pillow, duplicated commuters, cloned commuters, crowd blocking the payment, empty station, unreadable or nonsensical route signs, logos, branded clothing, captions, subtitles, watermarks, neon lighting, sci-fi gate, futuristic scanner, game-rendered look, harsh horror lighting, excessive motion blur, shaky footage, low resolution, blurry face, distorted anatomy, unrealistic reflections, loud beep, dialogue, narration, music, BGM, singing, sound mismatch.
Final Summary
Create one complete 15-second horizontal 16:9 photorealistic live-action comedy video at 30 fps. Use Reference Video only for natural low-camera tracking, motion continuity, and comic timing. The written prompt controls the single New York-style subway concourse, the exhausted American office worker, the pale-oak wheeled bed, the mounted green contactless reader, the one decisive card tap, the opening gate, and the final trailing shot.
The finished video should make the joke legible without dialogue: the man is too tired to leave his bed, but still follows the normal fare-payment ritual. Preserve the causal order, stable props, continuous camera path, realistic station materials, ordinary commuter behavior, one soft confirmation beep, and a clean final image of the bed rolling away into the concourse.
