A twelve-second vertical video: a girl balancing on one leg flicks a pile of clothes and shoes into the air and changes her outfit in a single frame

Prompt

PROMPT:
【Overall Requirements】 A 12-second photorealistic short video featuring a single outfit change, vertical 9:16. Strictly recreate the action logic of the reference video “Balance Outfit Change”: the female lead balances on one leg, using the outer side of her raised foot to support “a shoe + a pile of clothes,” flicks the entire pile into the air, quickly draws her leg back to gather power, performs just one high-speed kick and hits accurately; the instant her foot overlaps the clothes, her outfit changes. The outfit change must be a one-frame hard cut, not a fade, morph, or gradual covering of the body with clothing. No dialogue, no voice-over, no subtitles, no watermark; retain the background music. 【Character Lock】 The female lead is an adult woman aged 25 or older, using @1
. Her facial features, skin tone, hairstyle, height, and body proportions remain consistent throughout; no face swap, no age change, no change in body type. Her movements should show realistic balance and center of gravity, muscle exertion, breathing, and slight swaying as she keeps her balance. 【Outfit Lock】 Before the change: black short-sleeve T-shirt, light purple flared pants, black-and-white sneakers. After the change: the female lead instantly changes into the complete look preset as #1
, strictly preserving #1’s colors, cut, materials, and styling. The outfit changes only once in the entire video; the new look remains until the end. Do not add, remove, or replace any clothing, footwear, or accessories. 【Starting Clothing Bundle】 The opening prop is not a single shoe, but the footwear corresponding to the #1 look together with a pile of folded clothes stacked into a compact bundle with realistic weight. The shoe silhouette sits on top of the pile, with folded fabric supporting it from below and some fabric edges hanging naturally. The entire bundle of shoes and clothes is supported from underneath near the outer side of the female lead’s left sneaker, the outer instep, and the ankle. The prop is not placed on the toe, is not worn on the foot, and does not float. After being flicked into the air, the shoe and clothes must fly together as one combined bundle, not scatter into separate objects. 【Setting】 Minimalist modern home interior, white walls, light gray hard flooring, with a white wardrobe, door, washing machine, and a few household items in the background. Natural window light mixed with soft indoor lighting; furniture, background, and direction of light remain unchanged throughout. Realistic smartphone-video look, with natural skin texture and clearly rendered clothing and footwear materials. 【Fixed Close Camera Position】 Fixed, tight full-body shot. Camera approximately 2.1–2.3 meters from the female lead, about 1.05 meters high, approximately 30–32mm equivalent focal length, near eye level with a slight upward angle. When standing, the female lead occupies about 80% of the frame height and is positioned slightly to the right, leaving room on the left for the raised leg and the clothing bundle’s arc. Leave about 8% headroom and about 4% ground below the feet. The woman, supporting foot, raised left leg, and airborne clothing bundle remain fully in frame throughout. Camera remains fixed throughout: no zooming, panning, tracking, or cutting to close-ups. 【Strict Timed Storyboard】 [00:00-00:00.90] The female lead stands side-on, with her right leg as the sole supporting leg and her right knee slightly bent; she raises her left leg sideways until it is nearly horizontal. She turns her left foot slightly inward so the outer side of the sneaker faces up, like a small tilted tray. The shoes and folded clothes corresponding to preset #1 are stacked into a compact bundle, firmly supported by the outer side of her left foot. She turns her head to look at the entire pile of clothes beside her foot, focusing entirely on keeping the bundle balanced. Her arms lift naturally, while her right ankle, abdomen, and shoulders make realistic small adjustments. She does not look at the camera. [00:00.90-00:01.05] Using only her left ankle and the outer side of her foot, the female lead makes one short, distinct upward flick, sending the shoes and entire pile of clothes diagonally upward together. This is only a light flicking motion, not the actual kick. The entire bundle leaves the side of her foot and rises along a short arc. The edges of the fabric flutter slightly in the air, but the footwear and main bundle of clothes stay together without scattering. Accompany with a faint “whoosh.” [00:01.05-00:01.45] The clothing bundle rises quickly and approaches its apex. The female lead immediately draws her left leg back, rapidly bending her left knee toward her chest and abdomen and bringing her heel toward her body into a compact wind-up pose. Her body leans slightly to the right, supported solely by her right leg, while both arms extend naturally in response to the shift in balance. Her head and eyes track the entire pile of clothes throughout. She does not look at the camera, and does not pause to pose. [00:01.45-00:01.65] The clothing bundle passes its apex and begins to descend, with all the shoes and clothes still traveling along the same arc. The female lead completes her leg tuck and wind-up, pausing for no more than 0.2 seconds as she accurately judges the center of the bundle’s path. [00:01.65-00:01.85] The female lead performs just one official high kick, hitting accurately on the first attempt. Her left leg explosively extends diagonally upward from the bent-knee position, the knee opening rapidly as her lower leg and toes fully extend in about 0.2 seconds. The kick is fast, clean, and sharp, with natural motion blur and fabric cutting through the air; do not use slow motion. Her left foot accurately meets the entire descending pile of shoes and clothes: no missed kick, no slowing down, no correction, no second kick. [00:01.85, instant outfit-change hard cut] On the exact frame when her left foot first overlaps the center of the clothing bundle, make a seamless match-action hard cut. The frame before contact: the female lead is still fully wearing the black T-shirt, light purple pants, and black-and-white sneakers; the shoes and clothing bundle corresponding to preset #1 are still in the air. The frame after contact: the female lead is already fully dressed in the #1 look, strictly preserving #1’s colors, cut, materials, and styling; the airborne shoes, clothes, and accessories disappear completely at the same time. There are no transition frames in between. No half old outfit, half new outfit; no clothes growing from the skin; no fabric wrapping around the body; no color spreading or transparent crossfade. The outfit change is a one-frame hard cut between two complete states. The height and extension angle of the female lead’s left leg, body tilt, arm positions, face, background, and lighting are exactly the same before and after the cut. A deep, powerful “thump” hits in sync with the musical beat. [00:01.85-00:02.80] After the outfit change, the female lead holds the peak of the high kick for about 0.1 seconds, then lowers her left leg along its original path with control. She first looks toward her newly changed left shoe, her gaze following her leg as it descends. After her left foot lands steadily, she checks her stance, then slowly raises her head to look at the camera. Her expression naturally shifts from focused to composed and confident, with a slight smile. [00:02.80-00:04.10] The female lead strikes her first siren-inspired fashion pose: her body forms a soft S-curve, one hand rests on her hip while the other slowly brushes over her hair and shoulder. She first looks to the side of the camera, then slowly turns her gaze back, lifts her chin slightly, and gives a mysterious, confident, faint smile. The preset #1 look remains stable, strictly preserving #1’s colors, cut, materials, and styling. [00:04.10-00:05.40] She shifts into a three-quarter profile pose, with her feet naturally staggered, shoulders stretched back, and waist turning slightly. She looks directly at the camera, raises an eyebrow, and tilts her head gently, then slowly blinks, conveying subtle, playful allure while maintaining an elevated fashion-show style. [00:05.40-00:06.60] She smoothly turns around, presenting her back to the camera. Her hair falls naturally over her shoulders and back; the preset #1 look does not change. Once the turn is complete, she looks back at the camera over her shoulder, lifting one corner of her mouth slightly. [00:06.60-00:09.30] With her back to the camera, the female lead walks elegantly 3–4 steps deeper into the room, using a poised fashion-runway walk. Her feet alternate naturally, shoulders remain relaxed, and her arms swing slightly with her steps, giving her body a controlled, fluid rhythm. The camera remains fixed, recording her full-body figure from behind and the entire #1 look. No tracking, zooming in, or close-ups of body parts. [00:09.30-00:10.40] She stops in front of the background, lightly taps one foot to the rear side, still facing away from the camera, then looks back over her shoulder. She raises an eyebrow slightly, gives a mysterious sideways smile, and makes one brief, playful wink. [00:10.40-00:12.00] Final climax: as the last strong beat of the music hits, she suddenly makes one clean, sharp half-turn while tossing her hair, steps toward the camera, and stops in a three-quarter frontal pose. One hand rests on her hip; the other lifts near her chin. She raises her chin slightly and gazes directly into the camera with a confident, direct look and a mysterious siren-like quality. Her hair and the edges of her outfit form a natural arc of motion on the strong beat; hold the final pose for the last 0.3 seconds. 【Audio】 00:00–01:85: ethereal female humming, high notes, and slight reverb. Retain the sound of the supporting foot rubbing against the floor, soft fabric rustling, the “whoosh” of the clothing bundle being flicked into the air, and the rush of air from the high-speed kick. At 01:85, when the foot overlaps the clothing bundle, the music instantly enters a powerful electronic drum-and-bass Drop, synchronized with a deep “thump” impact. 01:85–12:00: continuous electronic beats; retain the sounds of shoes landing, footsteps, fabric rustling, and hair cutting through the air. Add a rising closing sound at the end. No dialogue, voice-over, or subtitles. 【Mandatory Negative Constraints】 No gradual outfit changes, dissolves, crossfades, gradually appearing clothes, fabric crawling up the body, color spreading, or old clothes slowly disappearing; no intermediate outfit states. The one-frame hard cut must happen when the foot first overlaps the clothing bundle: the frame before is 100% the old outfit, and the frame after is 100% the complete preset #1 look. Do not modify #1 in any way; do not change #1’s colors

【总体要求】 12秒写实系单次换装短视频，9:16竖屏。严格复刻参考视频《平衡换装》的动作逻辑：女主单腿平衡，用抬起脚的外侧面托住“鞋履＋一堆衣服”，将整堆衣物挑向空中，迅速收腿蓄力，只出一次高速踢腿并准确命中；脚与衣物重合的同一帧瞬间换装。 变装必须是一帧硬切，不是渐变、变形或衣服逐渐覆盖身体。无台词、无旁白、无字幕、无水印，保留背景音乐。 【人物锁定】 女主为25岁以上成年女性，使用@1
。面部五官、肤色、发型、身高与身形比例全程一致，不换脸、不变年龄、不改变体型。动作具有真实重心、肌肉发力、呼吸起伏和轻微平衡晃动。 【服装锁定】 变装前：黑色短袖T恤、淡紫色微喇长裤、黑白运动鞋。 变装后：女主瞬间换上预设#1
的完整造型，严格保持#1的颜色、版型、材质和搭配。全片只变装一次，换装后的造型持续到结尾，不增加、不删除、不替换任何服装、鞋履或配饰。 【起始衣物包】 开场道具不是单只鞋，而是预设#1造型对应的鞋履与一堆折叠衣服叠在一起，形成紧凑、具有真实重量的衣物包。鞋履轮廓位于衣物堆上方，折叠衣料从下方托住鞋，部分布料边缘自然下垂。 整堆鞋履和衣服被女主左脚运动鞋的外侧面、外侧脚背和脚踝附近从下方托住。道具不放在脚尖，不穿在脚上，不悬浮。挑起后，鞋与衣服必须作为同一个组合一起飞行，不能分散成多个物体。 【场景】 简约现代住宅室内，白墙、浅灰色硬质地面，背景保留白色衣柜、房门、洗衣机和少量生活用品。自然窗光混合柔和室内光，家具、背景和光线方向全程不变。真实手机视频质感，皮肤保留自然纹理，衣物和鞋履材质清楚。 【近距离固定机位】 固定紧凑全身景，摄影机距离女主约2.1—2.3米，高度约1.05米，约30—32mm等效焦段，接近平视并带轻微仰角。 女主站立时约占画面高度80%，位置略偏右，为左侧抬腿和衣物包抛物线预留空间。头顶保留约8%空间，脚底保留约4%地面。人物、支撑脚、抬起的左腿和空中衣物包始终完整入镜。全程固定，不推拉、不摇移、不跟拍、不切换特写。 【严格时间分镜】 [00:00-00:00.90] 女主侧身站立，右腿作为唯一支撑腿，右膝微屈；左腿向侧面抬起至接近水平。左脚略微向内转，使运动鞋外侧面朝上，像一个倾斜的小托盘。 预设#1对应的鞋履和折叠衣服堆叠成紧凑组合，被左脚外侧面稳稳托住。女主侧头注视脚侧的整堆衣物，注意力完全在衣物包的平衡状态上。双臂自然抬起，右脚脚踝、腰腹和肩膀进行真实的小幅调整。她不看镜头。 [00:00.90-00:01.05] 女主只用左脚脚踝和脚外侧做一次短促、清晰的向上挑动，将鞋履与整堆衣服同时挑向斜上方。 这只是一次轻巧的挑物动作，不算正式踢腿。衣物包整体离开脚侧，沿一条短促抛物线上升。衣料边缘受到空气影响轻微展开，但鞋履和主体衣服仍聚拢在一起，不散开。伴随轻微“嗖”声。 [00:01.05-00:01.45] 衣物包快速上升并接近最高点。女主立即收回左腿，左膝迅速弯曲靠近胸腹，脚跟收向身体，形成紧凑蓄力姿态。 她的身体向右侧轻微倾斜，右腿独立支撑，双臂随重心变化自然展开。头部与眼睛始终追踪整堆衣物，不看镜头，没有停顿摆拍。 [00:01.45-00:01.65] 衣物包越过最高点并开始下降，所有鞋履和衣服仍沿同一条抛物线运动。女主完成收腿蓄力，停顿不超过0.2秒，准确判断衣物包的中心落点。 [00:01.65-00:01.85] 女主只进行一次正式高踢腿，并且第一次便准确成功。 左腿从屈膝状态爆发式向斜上方伸直，膝关节迅速打开，小腿和脚尖在约0.2秒内完成完全伸展。出腿飞快、干净、利落，带有自然运动模糊和衣料破风感，不使用慢动作。 左脚准确迎向正在下落的整堆鞋履和衣服，不踢空、不减速、不修正、不补踢。 [00:01.85，瞬间换装硬切] 左脚与衣物包中心第一次重合的这一帧，立即进行无缝动作匹配硬切。 接触前一帧：女主仍完整穿着黑色T恤、淡紫色长裤和黑白运动鞋；预设#1对应的鞋履与衣物包仍在空中。 接触后一帧：女主已经完整穿上预设#1造型，严格保持#1的颜色、版型、材质和搭配；空中的鞋履、衣服和配饰同时彻底消失。 中间不存在任何过渡帧。禁止出现半边旧装、半边新装；禁止衣服从皮肤表面生长；禁止布料缠绕身体；禁止颜色扩散或透明叠化。变装就是前后两个完整状态之间的一帧硬切。 切换前后女主的左腿高度、伸展角度、身体倾斜、手臂位置、面部、背景和光线完全一致。音乐重拍同步响起一声低沉有力的“砰”。 [00:01.85-00:02.80] 换装完成后，女主保持高踢腿顶点约0.1秒，再控制左腿沿原轨迹下降。她先看向已经换装完成的左脚，目光随腿部下降。 左脚平稳落地后，她先确认站姿，再缓慢抬头看向镜头。神情从专注自然转为从容自信，嘴角轻微上扬。 [00:02.80-00:04.10] 女主摆出第一个海妖风时尚姿态：身体形成柔和S形曲线，一只手扶腰，另一只手缓慢掠过头发和肩侧。她先看向镜头侧方，再缓慢转回目光，下巴微抬，露出神秘、自信的浅笑。 预设#1造型保持稳定，严格保持#1的颜色、版型、材质和搭配。 [00:04.10-00:05.40] 她转换成三分之二侧身姿态，前后脚自然交错，肩部向后舒展，腰部轻微转动。她直视镜头挑眉、轻轻歪头，随后缓慢眨眼，表现含蓄、调皮的挑逗感，保持高级时装展示尺度。 [00:05.40-00:06.60] 她顺势缓慢转身，将背部朝向镜头。头发沿肩背自然滑动，预设#1造型不发生变化。转身完成后，她越过肩膀回头看向镜头，一侧嘴角微微扬起。 [00:06.60-00:09.30] 女主背对镜头向房间深处优雅行走3—4步，采用从容的时装走走秀步态。双脚自然交替，肩膀放松，手臂随步伐轻微摆动，身体产生克制、流畅的节奏。 摄影机保持固定，以完整背影全身景记录她的步态和整套#1造型，不跟拍、不放大、不使用身体局部特写。 [00:09.30-00:10.40] 她在背景前停下，一只脚向侧后方轻点地面，仍保持背向镜头，随后越过肩膀回头。她轻轻挑眉，露出神秘侧笑，并做一次短促的俏皮眨眼。 [00:10.40-00:12.00] 结尾高潮：音乐最后一个强拍到来时，她突然做一次干净利落的半转身，同时甩动头发，向镜头方向迈出一步，停在三分之二正面姿态。 她一只手扶腰，另一只手抬到下巴附近，下巴微扬，以直接、自信、具有海妖神秘感的目光凝视镜头。头发和服装边缘在强拍上形成自然运动弧线，最后0.3秒定格收束。 【音频】 00:00—01:85为空灵女声哼唱、高音与轻微混响，保留支撑脚摩擦声、衣料轻响、挑起衣物包的“嗖”声和高速出腿破风声。 01:85脚与衣物包重合时，音乐瞬间进入强劲电子鼓点Drop，并同步一声低沉“砰”重击音。 01:85—12:00持续电子节拍，保留鞋底落地声、行走脚步声、衣料摩擦声和甩发破风声。结尾加入上扬收束音。无对白、无旁白、无字幕。 【强制负面约束】 禁止渐变换装、溶解、叠化、衣服逐渐生成、布料爬上身体、颜色扩散、旧装慢慢消失；禁止任何中间变装状态。必须在脚与衣物包第一次重合时完成一帧硬切：前一帧百分之百旧装，后一帧百分之百预设#1完整造型。 禁止擅自修改#1；禁止改变#1的颜色
