Tàu xanh: gió cửa sổ, bốn cú cắt

Prompt gốc (nguyên văn)

[SPEC] 10 秒，16:9 横屏，30fps，1280×720，写实真人青春公路电影质感，4 个硬切镜头（切点 1.80 / 3.50 / 5.10 秒），手持摄影，偏冷低饱和调色。

[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，妆容为精致日常妆。乌黑长直发、无刘海，被风强烈吹动，多数时候飘向画面右侧。略宽松的水洗蓝牛仔外套内搭纯白 T 恤、深色直筒长裤、白色帆布鞋，腕上一只细银色手表。4 个镜头里保持同一张脸、同一发型、同一套服装鞋履与体型比例。

[SETTING & LIGHT] 白天行驶中的老式绿皮列车：打开的车窗、深色座椅、两节车厢间的金属踏板、橙绿色车厢外壳。窗外绿树与天空带明显运动模糊地快速向后掠过。日光从车窗与车门进入，人物多为逆光或侧光，车厢内偏暗、窗外偏亮。车窗灌入的强风持续吹动头发与外套。

[SHOT LIST]
0–1.80 秒（镜头 1，高机位俯拍中景，基本固定、仅轻微手持漂移）：她站在打开的车窗前，从一开始双手就抓着窗框上沿，手指明确扣住金属边缘。身体随车厢摇晃，头微歪、视线低垂、神情平静；重心在两腿间转换；镜头末尾风把头发吹过脸前。
1.80–3.50 秒（镜头 2，低机位全景，镜头匀速后退，硬切进入）：她穿过车厢连接处朝镜头正面走来，全身入画，直视镜头。自然交替迈步、左右手臂与脚步反向摆动；背景由昏暗车厢过渡到明亮连接通道。头发向后飘。切点精确卡在 1.80 秒的节拍上。
3.50–5.10 秒（镜头 3，低机位仰拍中景，镜头后退，硬切进入）：背景是明亮的橙绿色车壳与开阔天光。她把右手抬到头侧发旁，再顺滑放到锁骨高度，肩膀转回正对镜头；头先歪后正，眼睛始终看镜头。举手动作卡在 3.50 秒重拍上。
5.10–10 秒（镜头 4，略低机位中全景，机位相对车厢固定、随车摇晃）：她坐在深色座椅边缘向后靠，双掌撑在座垫上，背后车窗是强逆光。整个人是被车厢左右晃动带着摆，不是自己乱扭，双手始终撑住。头随晃动滚动，视线扫过车顶，到 8.80 秒慢慢回到镜头；8.80 秒后保持放松的正面注视、嘴唇微张，头发持续飘向画面右侧直到结束。

[TEXTURE] 真实列车震动、头发被风持续带动、手与窗框接触可信，窗框与座椅边缘清楚，头发不穿过窗框。

[SOUND] 节奏较快的电子流行器乐；三个切点都落在节拍上，镜头 4 的身体摇摆跟随节奏。底层是列车轰鸣与风声。

[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、镜头之间服装或发长变化、手穿过窗框或座椅、多指、手部畸形、肢体扭曲、腿部比例异常、同手同脚走路、火车结构变形、窗外景物静止、头发凝固、画面闪烁、过曝、字幕、文字、水印、暧昧眼神、亲密 POV。

Nghĩa tiếng Anh

[SPEC] 10 seconds, 16:9 landscape, 30fps, 1280x720, photoreal live-action youth road-movie look, 4 hard-cut shots at 1.80s / 3.50s / 5.10s, handheld camera, cool low-saturation grade.

[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 everyday makeup. Long straight jet-black hair, no fringe, blown strongly by the wind and mostly streaming toward frame-right. She wears a slightly oversized washed-blue denim jacket over a plain white T-shirt, straight-leg dark trousers, white canvas sneakers and a thin silver watch. Keep exactly the same face, hairstyle, outfit, shoes and body proportions in all four shots.

[SETTING & LIGHT] A daytime moving old-style green train: an open carriage window, dark seats, a metal gangway plate between two carriages and an orange-green exterior wall. Outside the window, green trees and sky streak backward with clear motion blur. Daylight enters through the window and door, so she is mostly backlit or side-lit, the carriage interior darker than the bright outside. Strong wind from the open window moves her hair and jacket continuously.

[SHOT LIST]
0-1.80s (shot 1, high-angle medium shot, almost fixed with slight handheld drift): she stands at the open window, both hands gripping the upper window frame from the start, fingers clearly wrapped over the metal edge. She leans with the train's sway, head tilted, gaze lowered, calm expression. Weight shifts from one leg to the other; the wind drives her hair across her face near the end of the shot.
1.80-3.50s (shot 2, low full-body shot, camera retreating at constant speed, hard cut in): she walks toward the lens through the gangway, full body in frame, looking straight at the lens. Natural alternating steps with opposite arm swing; the background changes from dim carriage to bright gangway. Her hair streams backward. Cut exactly on the beat at 1.80s.
3.50-5.10s (shot 3, low-angle medium shot, camera retreating, hard cut in): against the bright orange-green exterior wall and open sky, she raises her right hand to the hair beside her head and slowly lowers it to collarbone height, shoulders turning back to square with the lens; head tilts then straightens, eyes on the lens. The hand lifts on the downbeat at 3.50s.
5.10-10s (shot 4, slightly low medium-wide shot, camera fixed to the carriage so it sways with the train): she sits on the edge of a dark seat, leaning back with both palms braced on the cushion, strong backlight from the window behind her. Her whole body is swayed by the train's left-right motion, not by her own twisting; both hands stay planted. Head rolls with the sway, gaze passes across the ceiling and returns slowly to the lens by 8.80s; from 8.80s she holds a relaxed forward look with lips slightly parted, hair still streaming to frame-right until the end.

[TEXTURE] Real train vibration, continuous wind in the hair, believable hand-to-window-frame contact, visible window-frame and seat edges, no hair clipping through the frame.

[SOUND] Fast electronic-pop instrumental; the three cut points land on the beat, the body sway in shot 4 follows the rhythm. Train rumble and wind underneath.

[NEGATIVE PROMPT] face swap, drifting features, influencer-template face, Western/Caucasian bone structure, non-Asian face, underage or teenage look, outfit or hair length changing between shots, hand passing through the window frame or seat, extra fingers, deformed hands, twisted limbs, unnatural leg proportions, walking with the same-side arm and leg forward, deformed train structure, static scenery outside the window, frozen hair, flicker, overexposure, subtitles, text, watermark, suggestive gaze, romantic POV.
