[Style] Photorealistic fitness training short film, high-density beat-synced rapid cuts, sports-commercial quality, real strength and equipment physical feedback, 4K resolution, natural skin, sweat, and fabric texture [Duration] 12 seconds [Aspect Ratio] 9:16 vertical [Scene] A modern commercial gym, black-and-gray strength equipment, dark rubber flooring, large wall mirrors, a black ceiling with continuous white linear light strips; only a small number of blurred gym-goers in the background, never stealing focus [Character] Solo female lead @Image1; face shape, features, and body proportions strictly follow the reference image. Dark long hair tied into a natural low bun, with a few loose strands framing the sides; wearing a charcoal-gray long-sleeved fitted short henley-collar athletic top, gray high-waisted fitted leggings, white ribbed crew socks, and off-white thick-soled sneakers [Audio] No dialogue, no subtitles; clear, rhythmic workout electronic music, with barbell-plate clangs, machine-rail sliding sounds, breathing, and treadmill footsteps all landing precisely on the beat [00:00-00:02.25] Shot 1: Barbell Deadlift - Revealing from a Detail Shot (Deadlift Reveal) The very first frame is a low-angle close-up: the female lead grips the barbell with both hands, her feet about hip-width apart, her off-white sneakers planted firmly on the black rubber floor, with identically sized black weight plates loaded on either side of the bar. The female lead keeps her back naturally flat, her feet pressed into the floor, the barbell rising close along her shins. The camera tracks vertically up along the barbell (Vertical Tracking), passing in sequence over her hands, the gray high-waisted leggings, the charcoal-gray short athletic top, and finally arriving at the female lead's face. She stands upright by driving with her legs and hips simultaneously, the barbell rising close along her shins and thighs; at the top of the movement her body is fully upright, her shoulders naturally settling down, with no exaggerated leaning back. Cut to a close-up of her face: the female lead's gaze is focused straight ahead, her lips slightly parted, exhaling a short breath; her forehead and cheeks carry a small amount of genuine workout sweat. The barbell pauses briefly at the top of the movement, the weight plates wobbling slightly, accompanied by a low, deep metallic clang. [00:02.25-00:03.33] Shot 2: Second Deadlift - Full Movement (Full Deadlift) Hard cut to a side-rear full-body medium shot, the female lead entering frame together with the complete barbell. The female lead first pushes her hips back and bends her knees, lowering her body, her hands gripping the barbell steadily; then her feet drive down, the barbell lifting off the floor, rising smoothly close along her shins and thighs. Fully depicting: pushing the hips back and lowering the body; gripping the barbell firmly with both hands; the barbell leaving the floor; the barbell rising close along the legs; the female lead standing fully upright; the barbell pausing briefly in front of the thighs. The female lead keeps her body stable throughout, her gaze forward, her head not bobbing up and down with the barbell. [00:03.33-00:04.08] Shot 3: Deadlift Power Close-up (Power Close-up) Cut to a low-angle side-rear close-up. The female lead begins her next deadlift rep. The camera focuses on the barbell rising close along her legs, the fabric of her leggings stretching slightly with the muscle exertion, and the brief tremor of the weight plates from the inertia of the movement. The moment the female lead stands fully upright lands precisely on the music's heavy beat, immediately followed by a hard cut to the next exercise. [00:04.08-00:05.29] Shot 4: Barbell Hip Thrust The female lead's upper back rests against the edge of a flat bench, her feet planted firmly on the floor, knees bent; a padded barbell rests horizontally across her hips. A low-angle side shot: the female lead starts from a lower hip position, driving downward through her feet, steadily raising her hips and the barbell. At the top of the movement, her shoulders, hips, and knees form a stable straight line. Her hips pause briefly, then she controls the barbell as it lowers slowly. She completes one clear hip thrust rep in about 1.2 seconds -- it must not bounce quickly, and there must be no excessive arching of the lower back. Both hands stay naturally resting on the barbell pad throughout. [00:05.29-00:06.70] Shot 5: Leg Press, First Angle (Leg Press) The female lead sits into an inclined leg-press machine, her back and head resting against the black padded backrest, both hands gripping the handles on either side of the seat. A side medium shot: her feet, about shoulder-width apart, are planted on the center of the footplate, her off-white thick-soled sneakers and white crew socks clearly visible. The female lead first controls the footplate as it lowers, her knees drawing in toward her body; once she reaches a comfortable depth she immediately drives back in the opposite direction, smoothly pushing the footplate away. As her legs approach full extension, she keeps a slight bend, never fully locking out her knees. She completes one full "knees bend and lower -> feet drive -> footplate rises" cycle, the machine's rail producing a realistic mechanical sound. [00:06.70-00:08.45] Shot 6: Leg Press Rhythm, Continuous Reps (Leg Press Rhythm) Cut to a lower camera angle, closer to her feet, from the side. The female lead continues with two more clearly rhythmic leg-press reps: the first at a moderate tempo, lowering and pressing out; the second speeding up with the music, lowering slightly faster and pressing out more powerfully. The camera focuses on the bending and extending of her knees, her soles pressing against the footplate, and the inclined rail sliding. The female lead's hips, back, and head stay against the backrest at all times -- she must not lift off the seat. After the final press, her legs hold for about 0.2 seconds within a safe range, the music briefly pausing, before cutting immediately to the treadmill. [00:08.45-00:09.50] Shot 7: Treadmill Footwork, Beat-Synced (Treadmill Footwork) An extreme close-up of the treadmill belt. Her off-white thick-soled sneakers land alternately on the belt as it moves rapidly backward, with her white ribbed crew socks and the hem of her gray leggings clearly visible. Her left and right feet land continuously in time with the music's beat, each sole quickly pushing off the belt right after making contact; in one instant both feet briefly leave the belt at the same time, forming the natural airborne moment of running. The camera tracks close to the belt at a low angle (Low-angle Tracking), capturing the realistic impact of her footfalls, the compression of her soles, and the movement of the belt. [00:09.50-00:10.67] Shot 8: Face Close-up While Running (Running Close-up) The camera tilts up quickly from her running shoes to her upper body and face. The female lead maintains a steady running rhythm, both arms swinging naturally back and forth at her sides, her shoulders relaxed; her short athletic top and leggings show subtle, natural creasing as she runs. Cut to a close-up of her face: a few loose strands of hair sway gently as she runs, the female lead's gaze looking straight ahead, her lips slightly parted, her breathing a bit quicker, a small amount of genuine sweat on her cheeks. Her movements stay natural and restrained -- she does not look at the camera, and there is no posing. [00:10.67-00:12.00] Shot 9: End of Workout - Mirror Selfie (Mirror Selfie) A quick hard cut to a mirror selfie in the gym. The female lead stands directly in front of the mirror, her body angled slightly toward the mirror surface, one hand holding up a phone in front of her chest to take the photo; the phone is positioned below eye level, not fully covering her face. Her other hand gives a thumbs-up toward the mirror. The female lead first presses her lips together lightly, then breaks into a restrained, satisfied smile, her shoulders relaxed, her chest rising and falling gently with her post-workout breathing. The camera slowly pulls back from her upper body down to her thighs, showing off the charcoal-gray long-sleeved short athletic top, the gray high-waisted leggings, and her natural low-bun hairstyle. In the final 0.4 seconds she holds the thumbs-up pose, the female lead looking at the phone screen through the mirror's reflection, and the frame freezes to end. [Movement and Continuity Requirements] The training sequence is fixed: barbell deadlift -> barbell hip thrust -> leg press -> treadmill -> mirror selfie. The barbell deadlift must always have the barbell rise close along the shins and thighs -- it must never turn into a squat, a barbell row, or a clean and jerk. The hip thrust must be driven by the hips moving the barbell up and down -- it must never turn into a bench press. The leg press must have the footplate move along the inclined rail, with the character's body never sliding on the machine. The treadmill belt continuously moves backward, and the female lead's body stays centered on the treadmill at all times. Every equipment change uses a hard cut on the music's heavy beat -- no smoke, particle, or body-morphing transitions. [Negative Constraints] No second main character, no trainer assisting, no duplicating the female lead. No face-swapping, no hairstyle changes, no outfit color changes, or clothing drifting between top and bottom. No extra arms, extra legs, extra fingers, feet fused together, or joints bending in reverse. No barbell clipping through the body, no change in the number of weight plates, no equipment deformation, or footplate floating. No severe rounding of the back, knees caving inward, excessive arching during the hip thrust, or fully locking the knees during the leg press. Do not let the exercise movements lose their sense of load-bearing weight; no slow, posed movements. No complicated mirror duplication of the character; no extra female lead or incorrect movements appearing in the mirror. No dialogue, subtitles, titles, fitness-data stickers, logos, watermarks, or garbled text. No anime, cartoon, plastic CG skin, excessive skin smoothing, or exaggerated sweat effects. Generated by AI
✍️ Editor’s Notes

这条的骨架是「训练顺序固定」加结尾一整段负面清单,本质是在跟Seedance 2.5的动作漂移较劲——健身房器械稍微写含糊,模型就爱把硬拉画成深蹲,所以每镜都把发力链拆成脚下发力、杠铃贴腿上升、站直这种物理顺序,而不是笼统一句做硬拉。9个分镜卡着零点几秒的时间戳走,配合「由局部推进人物」这类运镜术语,把剪辑节奏也焊死,不给模型留自由发挥空间。负面词细到不要杠铃穿过身体、不要重量片改变数量,说明写的人是被模型的物理穿模坑过不止一次才总结出来的。
