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.
