一把椅子｜四个年代一镜到底

提示词原文（一字未改）

[SPEC] 12 秒，16:9 横屏，24fps，1280×720，超写实电影感时间转场，一镜到底不切镜，镜头绕着一位静坐的人物做缓慢环形运动，顶级真人实拍质感，柔和实用光。

[CHARACTER LOCK] 全片只有一名明确成年的 28 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，妆容克制的精致妆。四个年代里是同一张脸、同一体型比例、同一副平静从容的神情，始终几乎静止地坐在同一把椅子上。只有发型与服装变化，且只在镜头绕到她背后的三个瞬间切换：年代一为唐代高髻、暗赭色素面丝袍；年代二为宋代低盘髻、浅灰色交领长衫；年代三为 1930 年代短发、深蓝色棉质旗袍式连衣裙；年代四为现代齐肩黑直发、米白衬衫配炭灰长裤。不佩戴带可辨文字的饰物或道具。

[SETTING & LIGHT] 同一个房间，四个年代里几何布局完全一致：椅子位置相同，窗在左墙同一位置，小桌在她右侧同一位置，机位距离与镜头焦距也不变。只有墙面材质、器物与桌上物件更换：年代一为粗糙灰墙、陶杯与烛火；年代二为浅色粉墙、陶瓷瓶与编织席；年代三为深色木护墙、铜灯与几册书；年代四为干净白墙、柔和日光与合上的笔记本电脑。暖到中性的柔光，轻微胶片颗粒，年代变化可读但克制。

[SHOT LIST]
0–3 秒：年代一。镜头从正面中景开始缓慢环绕，带出粗糙墙面与烛光；她安静坐着，双手放在膝上，只有呼吸。
3–6 秒：镜头经过椅背、转到她身后时，房间与服装无缝切换到年代二；镜头看得见的范围内不做变形过渡；等她重新进入画面时，一切已经完全换好。
6–9 秒：下一次背后经过切到年代三；椅子、窗、桌位置不变；镜头抵达对侧，在她的侧脸上停留一拍。
9–12 秒：最后一次背后经过切到年代四；镜头完成环绕，收在干净的正面中景，人物依旧平静居中，不留空椅结尾。

[TEXTURE] 房间几何稳定，四个年代里椅腿与窗框一致，墙面不扭曲、家具不悬空，转场中不出现半件衣服或半截发型，脸不变形。

[SOUND] 一条连续柔和的环境底噪，随年代改变质感（烛芯轻响、远处鸟声、街面人声、安静室内底噪）。无对白、无音乐重音。

[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、出现第二个人、出现第二把椅子、空椅结尾、房间布局变化、窗或桌移动、镜头前可见的服装或发型渐变、切镜、溶解转场、墙面扭曲、物体悬空、多出的肢体、手部畸形、可读文字、历史名人、品牌名、Logo、字幕、水印、画面闪烁。

英文含义说明

[SPEC] 12 seconds, 16:9 landscape, 24fps, 1280x720, ultra-realistic cinematic time-transition sequence, one seamless continuous shot, no cuts, smooth slow circular camera orbit around one seated person, premium live-action realism, soft practical lighting.

[CHARACTER LOCK] One single clearly adult 28-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 makeup. The same face, same body proportions and same calm composed expression in all four eras; she stays almost perfectly still on the same chair. Only hairstyle and clothing change, and only at the three moments when the camera passes behind her: era 1, a Tang-dynasty high bun with a plain silk robe in muted ochre; era 2, a Song-dynasty low coiled bun with a pale grey cross-collar robe; era 3, a 1930s short bob with a dark-blue cotton qipao-style dress; era 4, a modern shoulder-length straight black hair with a cream shirt and charcoal trousers. No jewelry or props that show readable characters.

[SETTING & LIGHT] One room with exactly the same geometry in every era: the chair in the same position, the window in the same position on the left wall, the small table in the same position to her right, identical camera distance and lens. Only wall material, surface finish and the objects on the table change: rough lime wall, clay cup and candle in era 1; pale plaster, ceramic vase and woven mat in era 2; dark wood panelling, a brass lamp and stacked books in era 3; clean white wall, soft daylight and a closed laptop in era 4. Warm-to-neutral soft light, gentle film grain, readable but restrained era changes.

[SHOT LIST]
0-3s: era 1. The camera begins a slow orbit from a frontal medium shot, revealing the rough walls and candlelight; she sits calm, hands resting on her knees, only breathing.
3-6s: as the camera passes behind her chair, the room and her outfit transition seamlessly into era 2; no morphing in view; when she comes back into view everything is already fully changed.
6-9s: the next rear pass switches to era 3; same chair, same window, same table positions; the camera arrives at the opposite side and holds her profile for a beat.
9-12s: the final rear pass switches to era 4; the camera completes its orbit and ends on a clean frontal medium shot, still calm and centered, no empty chair.

[TEXTURE] Stable room geometry, consistent chair legs and window frame across all eras, no warping walls, no floating furniture, no partial clothing mid-transition, no face morphing.

[SOUND] A single continuous soft ambient tone with era-appropriate texture shifts (candle crackle, distant birds, street ambience, quiet room tone). No dialogue, no music stingers.

[NEGATIVE PROMPT] face swap, drifting features, influencer-template face, Western/Caucasian bone structure, non-Asian face, underage or teenage look, more than one person, more than one chair, empty-chair ending, changing room layout, moving window or table, visible morphing of clothes or hair in front of the camera, cuts, dissolves, warping walls, floating objects, extra limbs, deformed hands, readable text, historical figures, brand names, logos, subtitles, watermark, flicker.
