Create a native 15-second, vertical 9:16 real smartphone video: one continuous take with no cuts, recorded by a phone propped on a treadmill console in an ordinary gym. It must look like a real clip a girl filmed for her running progress that accidentally caught a guy next to her wiping out. No reference image. CORE RULES Two adults in focus: MAYA, a woman of 25, and DEREK, a man of 28. One continuous shot from the first frame to the last. The camera is fixed: the framing, the angle and MAYA's size in the frame stay exactly the same from the first frame to the last; no push-in, no zoom, no pan, the camera never follows the action. Each person keeps the same face, hair, body and outfit throughout. Each has exactly two arms and two legs; each hand has five fingers; joints bend only naturally. The recording phone is never visible. Natural, understated behaviour: nobody performs for the camera. Fluid real-time motion, no freezes, no slow motion. No readable text, numbers, logos or brand marks anywhere. CHARACTER Tone: a real, clumsy gym fail caught by accident. Funny because it is real. MAYA is a pretty 25-year-old woman, naturally attractive in an effortless, everyday way, with realistic body proportions and a full, natural-looking bust. Dark-brown hair in a slightly messy high ponytail with loose flyaways. She wears a plain black sports bra under a plain teal-grey zip hoodie, zipped halfway, plain black leggings, worn white running shoes and small white wireless earbuds in both ears for the whole clip. Light everyday makeup, slightly shiny skin from sweat. No logos. DEREK is a 28-year-old ordinary gym guy: short dark hair, short stubble, fit but normal build. He wears a plain faded navy t-shirt with a darker sweat patch on the chest, plain black shorts and grey running shoes. No logos. A plain clear water bottle stands in his cup holder. FACE MAYA: oval face, warm brown eyes, natural brows, small mole above the LEFT corner of her upper lip, natural white teeth. Calm, focused, a little tired running face, breathing through slightly parted lips. DEREK: square jaw, dark eyes, stubble. Competitive but trying to look casual; after the fall, a stunned, embarrassed face. Both: eyes focus on what they look at, gaze moves before the head, natural blinking, gradual expressions, head turns under 30 degrees. Nothing ever covers either face. No cartoonish faces, no shouting, no glassy eyes, no warped teeth. VOICE Only MAYA speaks, once, at the end: breathless, low, dry and amused, half to herself, soft American accent. Recorded by the phone microphone: slightly muffled, roomy, with gym noise under it. Every word matches her lips. DEREK makes only heavy breathing and one short "whoa" as he falls. CAMERA A phone propped upright in the holder of MAYA's treadmill console, front camera, lens at her chest height, about one metre in front of her, angled slightly up, wide front-camera field of view. Locked and static for the whole clip, with only a faint constant vibration from the running belt. The frame shows MAYA in the left-centre from the top of her head to her shoes, and DEREK on the treadmill directly to her LEFT, which is the right third of the frame, slightly further back in 3/4 profile, from head to shoes. The rear end of DEREK's treadmill and the bare gym floor right behind it are clearly visible in the right third of the frame. Horizon tilted about 3 degrees. The phone is never visible. This exact framing never changes. CAMERA HAND Nobody holds the camera. It stays propped the entire time. MAYA's hands only touch her own console button, just below the bottom edge of the frame. HANDHELD No handheld movement. Only the faint vibration of the treadmill. Never gimbal-smooth. LOOK Real smartphone front-camera footage: slight wide-angle distortion near the edges, mild noise in darker areas, light compression, auto-exposure that slightly overexposes the windows, auto white balance leaning a little cool under fluorescent light. Ordinary colours, flat contrast, no colour grading, no film look, no warm tint, no shallow depth of field. Natural skin with pores, sweat shine and redness. No beauty filter, no plastic skin, no glossy commercial finish. LIGHTING Available light from the ceiling fixtures and practical lamps present in the scene. Slightly uneven illumination, believable shadows and modest colour-temperature differences between existing light sources. Preserve realistic skin tones and readable surroundings. No added studio lighting, dramatic spotlighting or artificial glow. VISUAL MATCH The image must look exactly like an ordinary phone clip from a budget chain gym on a weekday evening: flat white fluorescent ceiling panels, a worn grey speckled rubber floor, a row of ordinary black treadmills, a mostly blown-out white window wall, a wall fan. Everything is in focus. Nothing looks styled, lit or composed. SETTING A regular budget chain gym in the evening. Two identical plain black treadmills side by side about one metre apart: MAYA's in front of the camera, DEREK's to her LEFT. Each treadmill has exactly two side handrails, four handrails in total, a plain console with a round speed button on its right side and a display showing only glowing bars, no numbers. Directly behind the rear end of DEREK's treadmill there is only the bare, worn grey speckled rubber gym floor, nothing placed on it. Behind: a row of more treadmills, a dumbbell rack, a wall fan and an overexposed window wall. Far in the back, about 10 metres away, two ordinary gym-goers do their own exercises. No mirrors, no mats. BACKGROUND Readable instantly as a real gym. Three layers: the top edge of MAYA's console at the bottom of the frame; MAYA, DEREK and the bare floor behind his treadmill in the middle; the treadmill row, the dumbbell rack and the two distant gym-goers behind. Palette: black machines, grey floor, white light, the navy shirt and teal-grey hoodie. Background story: DEREK's bottle rattles more and more as his speed rises; when he falls it pops out of the holder, drops to the floor beside his treadmill and rolls to a stop. At 12.6 s one distant gym-goer turns his head toward the noise and then goes back to his exercise without coming closer. The background never warps. MOTION Real running with weight: arms swing opposite to legs, ponytail bounces, feet land on the belt under the hips and get carried back. MAYA runs light and relaxed the whole clip and never breaks her rhythm. DEREK starts relaxed, then runs with tense shoulders and shortening steps. The fall is clumsy and real, with weight and momentum, and follows one simple path. Left and right sides never mirror. No freezes, no slow or sped-up motion, no posing. DEFECT PREVENTION Hands: MAYA's hands swing in loose fists; once, at 5.0 s, her RIGHT hand reaches down out of frame to her own speed button and returns. Her hands never rise to her face. DEREK presses his speed button only with his RIGHT index finger. During the fall both his palms land flat on the belt, then flat on the floor. At 14.0 s he raises only his RIGHT hand at chest height in a thumbs-up: four fingers curled, thumb up; his LEFT palm stays flat on the floor. Five fingers per hand; fingers never merge with the belt, rails, the bottle or the body. Face: both faces stay visible the whole time. During the fall DEREK keeps his head up; his face never touches the belt or the floor. Expressions stay real; head turns under 30 degrees. Body and legs: the fall follows one path only: his feet fall behind, he drops onto both knees and both palms on the moving belt, the belt carries him backward, he slides off the rear end onto the bare floor on his knees and hands, then sits back on the floor with both legs bent in front of him. No flips, no rolling, no twisting, no airborne body. Exactly two arms and two legs each, legs keep a constant length. Objects: two treadmills with exactly four handrails, one bottle that leaves the holder once at 11.4 s, drops to the floor and stays there, MAYA's two earbuds that stay in her ears. No mats or pads anywhere. Objects never vanish, duplicate, change shape or pass through bodies. No readable text, numbers or logos. Continuity: one continuous take, no cuts, identical framing and camera distance from first to last frame, same outfits, same light, MAYA always left-centre, DEREK always in the right third. Physics and environment: belts move steadily and speed up only after a button press; DEREK's empty belt keeps running at the same high speed until the end. Windows show no reflections. Nobody else comes near. STORYBOARD (15 s, one continuous take) START POSE: The first frame already shows MAYA mid-jog, ponytail mid-bounce, eyes on her display, and DEREK jogging beside her, already glancing sideways at her display with a small frown. 00:00.0-00:03.0 - Both jog at an easy pace. MAYA breathes steadily, one blink. DEREK's eyes stay on her display, then return to his own. FACE DEREK: a tight jaw. 00:03.0-00:05.0 - DEREK presses his speed button twice with his RIGHT index finger, a short beep each time; he runs faster and lifts his chin. FACE DEREK: a small satisfied smirk. 00:05.0-00:06.5 - MAYA, without looking at him, reaches down with her RIGHT hand, presses her own button once, returns to running a bit faster. FACE MAYA: calm, unbothered. 00:06.5-00:09.0 - DEREK glances at her display again, presses his button three quick times; his belt whines faster; his bottle rattles hard. He runs hard, shoulders tense, cheeks reddening, breathing loud. 00:09.0-00:11.0 - MAYA runs evenly. DEREK's steps get short and frantic, arms pumping wide, sweat on his forehead. FACE DEREK: eyes wide, trying to look casual. 00:11.0-00:11.6 - DEREK's feet fall behind the belt; a short "whoa"; he drops clumsily onto both knees and both palms on the moving belt. At 11.4 s his bottle pops out of the holder and drops to the floor. 00:11.6-00:12.4 - The belt carries him backward on his knees and hands; he slides off the rear end onto the bare rubber floor with a heavy, awkward thud, still on his knees and hands, head up. 00:12.4-00:13.2 - He sits back on the floor, legs bent in front of him, both palms on the floor, stunned; his empty belt keeps racing in front of him; the bottle rolls to a stop. At 12.6 s a distant gym-goer glances over. 00:12.6-00:13.4 - MAYA, still running, turns her head about 25 degrees toward the noise for half a second, then her eyes come back to the lens. FACE MAYA: brows lift slightly, then a slow suppressed smile. 00:13.4-00:14.6 - MAYA (low, breathless, dry; not loud, not mocking): "He was NOT warming up." 00:14.0-00:15.0 - Behind her, DEREK, still sitting on the floor, raises his RIGHT hand at chest height in a weak thumbs-up, embarrassed half-smile. MAYA keeps running with a small smile, upper teeth, never breaking her rhythm. SOUND Real phone audio: gym hum, treadmill belt whir rising with speed, short beeps on each button press, rhythmic footsteps, the bottle rattling, DEREK's heavy breathing, a short "whoa", the slap of his palms and knees on the belt, a heavy awkward thud on the rubber floor, the plastic clatter and roll of the bottle, his empty belt racing, distant clank of weights, faint gym music with no lyrics far away, MAYA's breathing and her one line. HANDS AND FEET Five fingers on each hand, never merging with each other, the belt, the rails or the bottle. Nobody touches their face. Exactly two arms and two legs each; knees follow the toes; while running, feet land on the belt and never slide sideways. CONTINUITY AND REALISM One continuous take. Two main people, two distant gym-goers, two treadmills, four handrails, one bottle, all in the same places from start to end. No mats, no floating or disappearing objects, no transformations, no captions, logos or watermarks. Everyone is an adult. FINAL FEEL A real, unedited phone clip from an ordinary gym that accidentally caught a guy losing an ego race and getting thrown off his treadmill onto the floor while she never misses a step. Real, imperfect, phone-recorded. Not a commercial. Not a fashion shoot. Not polished influencer content.
