Daytime. An adult man, carrying a visibly heavy black travel bag in his left hand, sprints at near-full effort through a busy but tidy modern city street. The camera is positioned diagonally across the street, moving roughly parallel to the man, continuously tracking him laterally with a handheld telephoto lens that carries a strong street-documentary feel. The man is already being chased; the opening has almost no setup — the very first second drops straight into a high-speed run. As he runs, he senses the pursuers behind him rapidly closing the distance; he glances back only once, very briefly, then immediately locks his focus back onto the route ahead. Two male pursuers quickly emerge from among the crowd, vehicles, café outdoor seating, and building entrances, continuously closing the gap. In the final seconds, the man suddenly changes course, using pedestrians and the street corner as cover to cut into a narrow, crowded pedestrian street; the camera rapidly adjusts direction to chase after him, but is ultimately blocked briefly by the dense crowd and roadside fixtures. Overall presentation: a real, fast-paced, urgent street-chase experience with a slight voyeuristic quality and a sense of on-the-scene loss of control. The pacing is noticeably faster than an ordinary chase scene, with almost no pauses or empty shots, but every movement still strictly obeys the laws of real human motion. Prohibited: slow motion; superhero-style superspeed; parkour-style leaps; exaggerated falls; teleportation; unreasonable camera acceleration; bullet time; props with no sense of weight; exaggerated special effects; deliberately posed movie-trailer-style shots. [Character Setup] The Running Man An adult male, approximately 28-35 years old. Medium-to-tall build, lean and fit, not an exaggeratedly muscular athlete type. Short-to-medium length dark hair, slightly disheveled from running and sweating, with some strands sticking to his forehead. Realistic skin texture. Retain: skin pores; sweat on the forehead; sweat sheen on the sides of the nose and temples; facial flushing from intense exertion; changes in the muscles of the mouth corners, jaw, and neck caused by rapid breathing. Prohibited: skin smoothing, filters, beautification, and plastic-looking skin. His expression remains in a state of heightened alertness throughout. His brow is slightly furrowed, his jaw tense, his lips continuously parted for breathing. Not panicked screaming, but a man rapidly calculating his escape route. Clothing: a white or light-gray fitted ribbed tank top; an open, lightweight dark-gray or beige-gray cardigan worn over it; dark straight-leg jeans with a high or normal waistline; understated, lightweight footwear suited to running in the city. The cardigan must be continuously affected by airflow and the twisting of his body. While running, its hem flares back, twists, and slaps against his body; when turning, it shows a clear inertial lag. [The Black Travel Bag] The man carries a soft black leather travel bag in his left hand. The bag has a very distinct sense of weight. It must never flutter in the wind like an empty bag. The man's left shoulder stays slightly lower throughout, his left arm continuously pulled downward by the bag. During high-speed running: the bag lags half a beat behind his body's motion; when his body accelerates forward, the bag temporarily falls behind; after each footfall, the bag swings forward again; the bottom of the bag repeatedly strikes his left thigh; when turning, inertia makes the bag briefly continue swinging in its original direction of travel. The leather surface shows realistic creasing, denting, and rebound as it is struck and compressed. Because the bag is so heavy, the man occasionally shortens the swing of his left arm and grips the handle even tighter. [The Two Pursuers] Initially about twelve to fifteen meters behind the man. The two chase him staggered front-to-back, rapidly closing the distance within 15 seconds. First Pursuer: Lean build, agile movements. Fast running rhythm. Skilled at slipping sideways through gaps in the crowd. Barely slows down amid pedestrians and street furniture, adjusting his line quickly just by rotating his shoulders and shifting his footwork. Second Pursuer: A heavier, more solid build. Slightly slower in absolute speed, but with a more pronounced sense of power. In crowded areas he must actively raise his arm, turn his body sideways, or change his stride to avoid colliding with: café tables; chairs; pedestrians; railings; street-side planters. His breathing is noticeably heavier. His clothing heaves visibly with each stride. [Setting and Space] A modern city-center street. Daytime. Natural daylight. The street is clean and busy, but not extremely congested. The environment includes: gray-white stone buildings; dark glass doors and windows; café outdoor seating; large spherical or square planters; metal railings; building steps; parked cars along the curb; slow-moving vehicles; pedestrians in suits, business-casual attire, and everyday clothing; in the distance, the entrance to a narrower, denser pedestrian street is visible. The main street is relatively open. The pedestrian street at the end is noticeably narrower and more crowded, containing: awnings; hanging signs; small roadside shops; dense crowds; tables and chairs; narrow passageways. The two spaces form a clear visual contrast with each other. [Camera and Cinematography] The entire piece is 15 seconds. A single continuous take. No editing cuts. No hidden jump cuts. No teleportation. No sudden changes in focal length. No unreasonable rapid push-ins. The camera remains diagonally across the street throughout, staying roughly parallel to the man. It uses the texture of telephoto street-documentary photography. The lens has a pronounced spatial-compression effect, making the subject, vehicles, pedestrians, and pursuers appear to occupy visually closer planes. The cameraman himself is also moving quickly. As a result the shot continuously shows: slight vertical bobbing; lateral inertia; small left-right sway; framing errors caused by running; brief loss of focus; refocusing; a faint sense of breathing. But it must not show violent handheld shake. It must not look like an action camera. It must not look like a drone. Overall it should look like a professional cinematographer, carrying a cine camera with a telephoto lens, desperately chasing and filming a real, suddenly unfolding pursuit from the other side of the street. [Core Camera-Movement Logic] Sequence of camera movement: quickly catches the man → tracks laterally close beside him → the man briefly looks back → foreground occlusion → focus shifts to the pursuers → the chase relationship rapidly compresses → the camera looks past the pursuers again to find the man → the man suddenly cuts into the pedestrian street → the camera chases urgently → ends when blocked from view. All changes in composition and focus must occur within continuous, realistic camera movement. They must not be achieved through editing cuts. [Detailed 15-Second Timeline] 0-2.5s | High-Speed Intrusion There is no establishing shot at the opening. The image is already in the midst of a busy city street. The foreground shows a roadside café, pedestrians walking by, and parked cars. At around the 0.3-second mark, the man suddenly bursts in at high speed from the left side of the frame. His speed is noticeably faster than every pedestrian around him. The camera immediately performs a fast but realistic pan, catching his face and upper body within about 0.5 seconds. At this moment the framing briefly overshoots, then is corrected right away. His body is clearly leaning forward. His right arm swings widely and quickly. His left hand grips the black travel bag tightly. On his first accelerating stride, the heavy bag noticeably lags behind his body due to inertia. Then, as the man's foot lands, the bag swings heavily into his left thigh. The cardigan is fully blown open by the high-speed airflow. Its hem flips backward, continuously twisting and slapping against his body. The man's lips are parted, his breathing already very rapid. His brow is furrowed. His gaze continuously scans the pedestrians, vehicles, and passable spaces ahead. A nearby pedestrian's shoulder and the edge of a car briefly blur past in front of the lens. The entire opening must plunge straight into chase mode. 2.5-5s | High-Speed Glance Back to Confirm The camera keeps moving laterally at high speed, parallel to the man. The shot gradually tightens from a medium shot (above the thighs) to a medium close-up (above the waist). The man suddenly hears footsteps behind him growing denser and closer. His reaction must be extremely fast. Not a pause followed by a look back. Sequence of motion: his eyes first dart quickly to the rear-left; then his chin lifts slightly; his right shoulder keeps driving forward; his left shoulder rotates backward; his neck follows quickly; his head turns back for only about half a second. The entire glance-back is very brief. In the instant he looks back: his upper eyelids rise; his pupils quickly lock onto the distant pursuers; his nostrils flare sharply; the muscles of his jaw and neck visibly tense; sweat forms a brief highlight at his temples. His hair is flung sideways by the inertia of the turn. Because his attention momentarily leaves the path ahead, his right foot lands off-target. The man nearly brushes against an oncoming pedestrian. The pedestrian instinctively turns sideways. At the same moment the man quickly raises his right hand to keep his balance. His left hand grips the bag strap even tighter. He does not stop. There is no noticeable slowdown. On the very next step his cadence immediately picks back up. 5-7.5s | An Occlusion Appears, the Pursuers Enter Frame The pace continues to accelerate. A dark SUV, the edge of a delivery van, or a large square planter suddenly enters the close foreground. It blocks most of the frame for about 0.4-0.6 seconds. The camera does not stop moving. While the occlusion occurs: the shot keeps panning right at high speed; the camera slightly reduces its panning speed; focus begins shifting quickly from the man's position at front-right toward the rear of the street. The occlusion passes. The man has now reached a position further toward the right of the frame. Only a brief, slightly out-of-focus silhouette of him running at high speed is visible. At this moment the two pursuers suddenly burst out from among a building entrance, the crowd, and the café. The camera immediately catches the two pursuers. The leaner pursuer quickly turns sideways, slipping between two oncoming pedestrians. His shoulder passes within a hair's breadth of one of them. The heavier pursuer comes rushing in from the other side. He raises his right arm to avoid the café's parasol and tables and chairs. His feet slip very briefly from the sharp turn. His upper body tilts outward. But he regains his balance immediately on the next step. He does not fall throughout. The camera continues tracking to the right. 7.5-10.5s | The Chase Distance Rapidly Compresses The telephoto lens's spatial-compression effect intensifies further. The frame now shows a three-layer chase relationship: farthest ahead is the fleeing man; in the middle is the leaner pursuer; slightly behind is the heavier pursuer. The three figures are visibly compressed together within the telephoto frame. The chase rhythm is faster than in the first half. The leaner pursuer clearly begins closing the gap. He lowers his center of gravity. His stride rate rapidly increases. His arms pump at high speed. He repeatedly threads through gaps between pedestrians to push forward. The heavier pursuer follows close behind. His chest heaves violently. His breathing grows heavier and heavier. His clothes keep slapping against his body as he runs. Ahead, the man begins rapidly changing his running line. He first cuts past the front of a car. Then weaves diagonally between two pedestrians. The heavy travel bag strikes the side of his leg twice in a row. The man suddenly glances back again, very briefly. Only his eyes and head turn slightly. It lasts less than half a second. The camera's focus briefly drifts away from the leaner pursuer's face. Passing over his shoulder. It settles momentarily on the distant man's face. Then, because the cameraman is still running at high speed, focus drifts again and is quickly recaptured. The whole process must convey the feeling of a real cameraman continuously searching for the narrative subject. 10.5-12.5s | The Camera Forces Its Way Past the Pursuers The camera suddenly speeds up its pan. It no longer lingers on the pursuers for long. The shot moves directly along the two pursuers' direction of travel, "searching" ahead for the man. Building columns, railings, glass display windows, vehicles, and roadside pedestrians begin to show more pronounced horizontal motion blur. But the main subject must not be reduced to a full motion smear. A pedestrian very close to the camera suddenly crosses the frame. His shoulder and body create a second brief, natural occlusion. The occlusion lasts about 0.3-0.5 seconds. The camera uses this occlusion to complete a shift in framing. When the occlusion ends, the man reappears slightly right of center in the frame. By now he has nearly reached the end of the main street. The pedestrian-street entrance lies just ahead. 12.5-15s | A Sudden Cut of the Line, Charging Into the Pedestrian Street The pacing hits its peak in the final 2.5 seconds. The man is now visibly exhausted. His forehead and temples are entirely glistening with sweat. His chest heaves violently. His mouth is open, gasping rapidly. The travel bag repeatedly slams hard against his left thigh. The man glances back one last time, very briefly. His gaze passes directly across the camera's direction, toward the closing pursuers. His pupils contract instantly. His expression shifts rapidly from fear to clear-headed decision-making. He spots the narrow pedestrian-street entrance ahead to his right. In the next instant he snaps his attention back forward. No pause. The man abruptly lowers his center of gravity. His right foot stamps hard onto the ground. His shoe sole produces a clear scraping friction. His right leg drives outward, pushing off the ground laterally. His left shoulder rotates first into the new direction. His waist follows closely. His body cuts diagonally around the street corner. Because the bag is so extremely heavy, even after the man has changed direction, the black travel bag continues to swing outward in his original direction of travel due to inertia. His left arm is instantly yanked straight outward. He then forcibly hauls the bag back in with his arm and shoulder. The bag slams heavily back into his thigh and hip. The camera immediately registers the man's change of direction. The shot rapidly shifts from its original horizontal pan into a diagonal chase into the pedestrian street. The cameraman's footing clearly becomes unsteady. The frame produces a more pronounced but still realistic and controlled vertical wobble. The man charges into the narrow pedestrian street. On both sides: pedestrians noticeably increase; awnings lower the visual headroom; hanging signs whip past quickly; tables, chairs, and shops form a narrow passage. The man begins weaving sideways through the crowd at speed. Just as the camera tries to keep locking onto him: a nearby pedestrian; a hanging sign; and the edge of an awning create a series of brief, partial occlusions. When the view clears again, the man has already moved deep into the pedestrian street. Only his gradually shrinking silhouette from behind and the black travel bag swinging steadily side to side are still visible. The next second, he vanishes completely into the crowd. The camera does not keep pushing forward frantically. It finally settles near the entrance of the pedestrian street. The shot still carries a slight tremor from the cameraman's rapid breathing. The distant crowd refills the frame. The man is now completely out of sight. But behind him, the footsteps and gasping breath of the two pursuers closing in at high speed grow louder and louder. The shot ends. [Pacing Requirements] The entire video must present a clearly accelerating structure: 0-2.5s: immediately enters the chase 2.5-5s: quick glance back to confirm 5-7.5s: the pursuers rapidly appear 7.5-10.5s: the distance rapidly compresses 10.5-12.5s: the camera actively overtakes the pursuers to find the protagonist 12.5-15s: the highest-speed turn into the pedestrian street No meaningless pause longer than 0.5 seconds is allowed. The character must not stop to observe his surroundings. The camera must not stop to showcase the city. All environmental information must be conveyed naturally during high-speed movement. [Sound Design] No background score throughout, or only an extremely faint low-frequency tension ambience. The focus is on emphasizing authentic environmental sound. The protagonist's footsteps are fast and dense. His shoe soles produce a clear scraping sound against the stone pavement. The black travel bag repeatedly strikes his jeans and body, producing a dull thud of leather impact. The man's breathing is already noticeably rapid from the opening, and grows even heavier as time goes on. The cardigan slaps rapidly against his body. The sound of vehicles passing by. The sound of pedestrians talking. The faint clink of café tableware. Once the pursuers appear, the footsteps behind him gradually become clearer. The heavier pursuer has noticeably heavy, labored breathing. When the man finally turns into the pedestrian street: the sharp scraping sound of his shoes turning; the violent swinging sound of the travel bag; the street crowd's noise suddenly becomes denser. After the shot ends, the protagonist has already disappeared. But the footsteps of the two pursuers, rapidly closing in, continue to approach. [Final Visual Requirements] Cinema-grade realistic photography. Real natural daylight. Real human body dynamics. Real inertia. Real fabric dynamics. Real leather weight and deformation. Real sweat. Real motion blur. Real depth of field. Real telephoto compression. Reasonable focus drift is allowed. Slight exposure variation is allowed. Brief compositional deviation is allowed. Natural foreground occlusion is allowed. It must feel like a real chase event that actually happened on a city street, one the cameraman happened to catch and desperately chased after to film.

✍️ Editor’s Notes

五千多字的巨长提示词,重点不在讲故事而在防跑偏——「禁止:慢动作;超级英雄式高速;跑酷飞跃;夸张摔倒;瞬移」这一串否定词几乎把追逐戏常见滥用套路点了个遍,还专门给旅行袋写物理设定,强调「它绝对不能像空袋子一样随风飘动」,这是在用文字硬掰模型对重量的感知。这种靠关键词密度堆写实感的打法,适合物理模拟强的模型,遇到偏卡通渲染或爱加特效的模型基本白搭,细节写得越多越容易被选择性忽略。
