Studio đen trắng: xoay cầm tay và dừng dứt khoát

Prompt gốc (nguyên văn)

[SPEC] 8 秒，16:9 横屏，24fps，1280×720，高反差黑白真人舞蹈短片，一镜到底手持拍摄，不切镜，单一硬主光，细颗粒胶片质感。

[CHARACTER LOCK] 一名明确成年的 26 岁东亚女性，东亚骨相特征清晰：柔和鹅蛋脸、深棕色杏仁眼带浅双眼皮、鼻梁细直、唇形自然，妆容为克制的精致舞台妆。乌黑长直发自然披散、垂到背部中段。纯黑色长袖合体练功上衣、黑色直筒长裤、黑色软底舞鞋；无印花、无首饰。全片保持同一张脸、同一发型、同一套服装与体型比例。

[SETTING & LIGHT] 完全空旷的白色片场：白地面、白背景纸，没有家具、道具与墙面标记。单盏硬光从画面左侧高位打来，身体上有干净深黑，背景是明亮纯白，高反差黑白调色。身体与面部用高速快门，只有头发带运动模糊。

[SHOT LIST]
0–2 秒：她从画面左侧向右侧低身弓步滑出，双臂水平展开，上身接近与地面平行，长长的黑发随惯性几乎横向甩起。手持机位在胯部高度、略靠她身后。
2–5 秒：手持镜头升到肩高，跟着她起身并旋转两圈，全程贴近；头发有一次扫过镜头，形成柔和的发丝虚影并短暂遮住部分画面，白色背景随之在身后摆动。只要脸露出来就必须清晰。
5–8 秒：她在一拍之内急停，一只张开的手掌推向镜头；镜头快速推近到这只手，最后几缕发丝缓缓落定。收在这个手部紧特写上，她稳定的脸在手后虚焦处，保持到结束。

[TEXTURE] 全画面细颗粒，身体边缘锐利，只有运动中的头发带模糊；肢体不重影、脸不拖影，不使用数字变焦——所有推近都是真实的摄影机移动。

[SOUND] 干净的打击乐，两个重音对应两次旋转，5 秒处一次硬停；只保留房间自然混响。

[NEGATIVE PROMPT] 换脸、五官漂移、网红模板脸、欧美骨相、非东亚面孔、未成年观感、浅色或金发、彩色画面、道具、家具、多出的舞者、肢体扭曲、多指、手部畸形、爪状手、重影、全画面运动模糊、脸部拖影、数字变焦、三脚架固定机位、切镜、字幕、文字、Logo、水印、画面闪烁。

Nghĩa tiếng Anh

[SPEC] 8 seconds, 16:9 landscape, 24fps, 1280x720, high-contrast black-and-white live-action dance film, one continuous handheld take, no cuts, hard single key light, fine film grain.

[CHARACTER LOCK] A clearly adult 26-year-old East Asian woman with distinctly East Asian features: soft oval face, dark-brown almond eyes with subtle double eyelids, a fine straight nose bridge, naturally shaped lips, and polished understated stage makeup. Long straight jet-black hair, loose and unbound, reaching the middle of her back. She wears a plain black long-sleeved fitted dance top, black straight-leg trousers and black soft dance shoes; no print, no jewelry. Keep exactly the same face, hairstyle, outfit and body proportions for all 8 seconds.

[SETTING & LIGHT] A completely empty white studio: white floor, white cyclorama, no furniture, no props, no marks on the wall. One hard key light from camera-left high, deep clean blacks on the body, bright white background, high-contrast monochrome grade. Fast shutter on the body and face, motion blur only in the hair.

[SHOT LIST]
0-2s: she lunges low across the white floor from frame-left to frame-right, arms spread wide and level, torso close to horizontal, long black hair flung out almost horizontally with the momentum. Handheld camera at hip height, slightly behind her.
2-5s: the handheld camera orbits with her at shoulder height, staying close as she rises and spins twice; her hair whips across the lens in a soft blur of strands once, briefly veiling part of the frame, and the white background swings behind her. Keep her face sharp whenever it is visible.
5-8s: she stops dead in one beat, one open palm thrust toward the lens; the camera snaps in on that hand as the last strands of hair settle. Hold the tight hand shot, with her steady face just behind it out of focus, to the end.

[TEXTURE] Grain over the whole image, crisp body edges, blurred only the moving hair, no ghosting on limbs, no smeared face, no digital zoom: every push is a physical camera move.

[SOUND] A dry percussive track with two clear accents matching the two spins and one hard stop at 5s; room reverb only.

[NEGATIVE PROMPT] face swap, drifting features, influencer-template face, Western/Caucasian bone structure, non-Asian face, underage or teenage look, pale or blonde hair, colored image, props, furniture, extra dancers, distorted limbs, extra fingers, deformed hands, claw-like hand, ghosting, full-frame motion blur, smeared face, digital zoom, tripod-locked shot, cuts, subtitles, text, logo, watermark, flicker.
