12 秒手机实拍短片，怎么做出来的？

PROMPT HEADER:
Create a 12-second vertical 9:16, 24 fps, ultra-realistic live-action viral smartphone video, filmed as ONE CONTINUOUS HANDHELD SHOT. Use @Reference Image as the exact protagonist reference and use @Reference Video only as a broad reference for authentic handheld smartphone movement, chase pacing, natural camera response, and the final physical-comedy payoff. The reference sheet shows three views of ONE young woman, not three different people. Preserve her same face, fair skin, shoulder-length wavy auburn hair, natural proportions, and outfit throughout: a loose black-and-white horizontally striped long-sleeve top, matching striped pants, and black slip-on shoes. She cradles an oversized open paper carton against her chest, overflowing with a comically tall mound of golden French fries. One separate fry sticks out from between her lips. The carton, the mound of fries and the fry in her mouth remain recognizable throughout. No identity, hairstyle or wardrobe changes.
SCENE: a quiet outdoor urban pedestrian passage in natural daylight. Reddish brick pavement beside one very tall, completely flat beige concrete/stone wall with soft tree shadows. Painted directly onto this single flat wall is one trompe-l’oeil mural consisting of BOTH a diagonal concrete staircase AND a single brown wooden door at the top.
Make the painted staircase longer and more clearly inclined across the wall: around 12–14 visible painted steps stretching a substantial horizontal distance from the lower-right near ground level to the single upper-left door. The woman’s climb travels sideways as well as upward, rather than almost vertically beneath the door. Keep the full diagonal staircase and door natural within the vertical composition.
CRITICAL CONCEPT: BOTH THE STAIRCASE AND THE CLOSED DOOR ARE FLAT 2D PAINTINGS. At the beginning there is NO real staircase and NO real architectural door. The gray stair treads, risers, shadows, door frame, wooden panels, upper glass panes, handle and all apparent depth are painted directly onto the same smooth vertical wall. From the camera angle they look highly three-dimensional, but physically the wall is perfectly flat. No protruding steps, no real ledges, no landing, no recessed doorway, no existing black opening.
The surreal joke is that only the woman can physically use these painted elements as if they were real.
[0.0–2.0s] Start immediately on a handheld upper-body close shot of the woman in the outdoor passage, filmed from slightly in front of her at natural phone-camera height. Her face is clearly visible and matches the front view of @Reference Image. The close shot also shows the towering pile of fries in her arms and the single fry between her lips. She is moving past the camera when approaching police footsteps and a distant English shout are heard from off-screen behind her. Her eyes flick sharply toward the sound; her expression shifts from alertness to startled fear as she realizes they are closing in. She hugs the carton tighter, glances toward the painted staircase, makes a split-second decision and pivots into a run, still holding the fry in her mouth. The camera operator reacts with her, stepping back and swinging the phone in the direction she runs. This movement naturally opens the frame into the following wide view without a cut. The officers remain off-screen during this opening reaction.
[2.0–2.5s] The same continuous handheld movement settles into a wide smartphone shot showing the tall beige wall, brick pavement, the full longer diagonal painted staircase and the single painted closed door at the top. The mural looks astonishingly real from this angle.
[2.5–5.0s] The woman from @Reference Image runs in from the lower right. Without stopping, she turns toward the wall and sprints upward along the PAINTED staircase. She keeps the overflowing carton braced against her body; the tall pile of fries wobbles slightly with her movement while the fry remains between her lips. Her black shoes land exactly on the painted tread positions as though invisible solid steps exist there. She climbs quickly across all 12–14 painted steps, moving diagonally upward with believable running mechanics and natural body movement.
CRITICAL: nothing appears beneath her feet. The staircase mural never extrudes, grows, unfolds or becomes real. The wall stays flat. She alone mysteriously behaves as if the painted stairs are solid. The handheld camera pans and tilts upward to follow her while staying far enough away to preserve the optical illusion.
[5.0–5.9s] She reaches the final painted step directly in front of the PAINTED DOOR. Until this moment, the door is still only a completely flat painting: no thickness, no recessed doorway and no dark interior.
Holding the carton against her body with one arm, she reaches for the PAINTED handle with her free hand and pushes it. The exact flat painted door suddenly functions like a real hinged door and swings INWARD, away from her and into the space behind the wall. Do not show any magical transformation. The same single painted brown door leaf simply begins rotating inward while preserving the same wooden-panel and upper-glass-pane design.
Only as that one door swings inward does a dark rectangular doorway appear behind it for the first time. The woman crosses the very thin threshold with the carton of fries and disappears inside. Keep the same single door visibly OPEN inward after she enters. No second door appears beside the opening. No platform or balcony appears beneath it.
[5.9–6.7s] Two white Western male police officers in realistic dark navy uniforms, utility belts and caps rush into the lower frame chasing her. They stop abruptly and stare upward at the impossible staircase and still-open elevated door, confused. Their brief reactions are spoken naturally in English.
[6.7–8.8s] One officer approaches the apparent staircase while the handheld camera moves closer. He reaches toward what looks like thick concrete steps and places both palms directly on them.
REVEAL: his palms press completely flat against one smooth vertical wall. There is zero depth. He pats and slides his hands across several painted stair edges. His fingers move continuously over the fake boundaries and cannot grip anything.
[8.8–9.5s] The camera backs away slightly. One officer keeps staring toward the open doorway and decides to imitate the woman. He backs several steps away on the brick pavement and prepares for a short run. The second officer remains near the wall.
[9.5–10.8s] He sprints toward the painted staircase and jumps. Both palms slap against the flat wall and he tries to plant one shoe on a painted tread exactly as the woman did. Nothing supports him. His shoes scrape downward across the smooth painted surface and he awkwardly scrambles for a moment before losing support. The mural NEVER becomes physical for him.
[10.8–12.0s] He slides and falls awkwardly back onto the brick pavement near the camera. The phone operator reacts naturally, quickly dipping and tilting downward with the fall. End on a close handheld view of the fallen officer reacting in frustrated disbelief while the second officer remains nearby.
CAMERA STYLE: authentic casual viral smartphone recording, subtle handheld shake, imperfect human framing, realistic autofocus breathing and normal phone-camera motion blur. Camera movement only through walking, panning and tilting. No drone, orbit, crane or impossible floating camera.
LIGHTING AND REALISM: ordinary bright daytime exterior, neutral exposure, natural tree shadows, realistic skin, auburn hair, black-and-white striped fabric, golden fries, paper carton, painted wall and brick textures. It should feel like an impossible real event unexpectedly captured on a phone.
AUDIO: natural outdoor ambience, a distant English shout from an officer, running footsteps, breathing, shoe contact, door-handle movement, wooden door creak, police footsteps and brief natural English reactions of confusion, palms hitting the wall, shoe soles scraping the flat wall and believable body impact. No narrator or dramatic soundtrack.
STRICT NEGATIVES: no real staircase at the beginning, no real door at the beginning, no recessed doorway before opening, no permanent black doorway, no deep door tunnel, no balcony, no landing, no protruding stairs, no staircase extrusion or materialization, no second door, no outward-swinging door, no door changing design, no magical glow, no portal effect, no wall melting, no teleportation, no hidden cuts, no jump cuts, no slow motion, no replay, no duplicated characters, no identity drift, no wardrobe changes, no cartoon physics, no gore, no text, no subtitles, no logos, no watermark. @Reference Image
Final Summary
Create one complete 12-second vertical 9:16 photorealistic live-action smartphone comedy at 24 fps. Use Reference Image as the fixed identity and wardrobe source for exactly one auburn-haired woman in a black-and-white striped outfit, and use Reference Video only for broad handheld movement, pursuit rhythm, and the final failed-climb gag.
The finished video must make the central visual rule immediately understandable: the long staircase and closed door begin as flat 2D paint on one smooth beige wall. Only the woman carrying the tall carton of fries can run across the 12 to 14 painted steps, open the painted door inward, and disappear through it. The two officers reveal the wall is flat, fail to imitate her, and end with one natural fall. Preserve the protagonist's identity, carton, fry in her mouth, diagonal mural geometry, one inward-swinging door, continuous handheld camera path, short natural English reactions, real-time pacing, and no watermark.
