High-Speed Rail Journey Cinematic Documentary

Portrait 9:16, 10-second short video, 60fps, realistic mobile travel documentary style, natural handheld slight shaking throughout, non-mechanical jitter, lens with a lifestyle breathing feel.
Scene: High-speed rail carriage window seat, cool white clear tones, low saturation, light film grain, side backlight creating hair contour light, soft light without hard shadows. Digital human long-haired girl, cool and lazy temperament, all actions slowed down by 35%, soothing rhythm. Camera movement & action sequence:
0-1s Close-up, side profile looking out the window, camera pushes forward extremely slowly, low amplitude slight shaking;
1-2s Same position transition, character stationary, long hair blowing in the wind, shaking unchanged;
2-3s Medium close-up, gently lifting a strand of hair, camera follows hand movement with small range;
3-4s Medium shot, leaning forward, camera pans slightly downward, vertical shaking slightly increases;
4-6s Close-up, slowly turning head toward the camera, camera pulls back + small range circular micro-movement, medium natural handheld shaking;
6-7s Face close-up, camera locked, retaining extremely subtle shaking, eyes looking at the camera, expression indifferent;
7-8s Close-up, turning head to look out the window, camera slowly pulls back to regular perspective, shaking weakens;
8-10s Medium close-up freeze-frame ending, fixed camera, weakest amplitude micro-shaking, character stationary leaning against the seat.

No special effect transitions throughout the film, seamless lens transitions, low-key and soothing camera movements, natural and smooth dynamics, realistic physical hair movement, 4K ultra-clear, avoiding mechanical AI feel, the image has the relaxed texture of live-action filming.

竖屏9:16，10秒短视频，60fps，真人手机旅拍纪实风格，全程自然手持轻微晃动，非机械抖动，镜头带有生活化呼吸感。
场景：高铁车厢靠窗座位，冷白清透色调，低饱和度，浅胶片颗粒，侧逆光打造发丝轮廓光，柔光无硬阴影。 数字人长发女生，气质清冷慵懒，动作全部慢放35%，节奏舒缓。 镜头运镜&动作全程： 
0-1s 近景，侧脸望窗外，机位极缓慢前推，低幅度微晃；
1-2s 同机位衔接，人物静止，长发被风吹动，晃动不变；
2-3s 中近景，抬手轻柔撩发丝，镜头随手部小幅跟移；
3-4s 中景，身体向前探身，镜头微向下平移，上下晃动略加重； 
4-6s 近景，缓慢转头朝向镜头，镜头回拉+小范围环形微运镜，中等自然手持晃动；
6-7s 面部特写，机位锁定，保留极细微晃动，眼神看向镜头，表情淡然； 
7-8s 近景，转头望向窗外，镜头缓慢拉回常规视角，晃动减弱； 
8-10s 中近景定格收尾，固定机位，最弱幅度微晃，人物静止倚靠座椅。 

全片无特效转场，镜头无缝衔接，运镜低调舒缓，动态自然流畅，毛发物理飘动真实，4K超清，规避机械AI感，画面有真人拍摄的松弛质感。
