[Video Specifications] 14 seconds, 9:16 vertical screen, 30fps, realistic creative outfit change video. The female lead completely blocks the lens with her fist, whole pant leg, and medical props, completing hard cuts of nine outfits within the blockage. No dialogue, voiceover, lip-syncing, subtitles, text, logo, or watermark. [Realism Prefix] Authentic mobile native camera quality, ordinary indoor overhead lighting, auto exposure, auto white balance, continuous autofocus. No beauty filter, skin smoothing, or cinematic color grading. Preserve realistic skin, blinking, breathing, hair inertia, clothing wrinkles, fabric gravity, plastic refraction, and metal reflection. When a fist, pant leg, or prop suddenly approaches, focus briefly hesitates before shifting to the foreground, naturally blurring the person; focus returns to the person after the object leaves. Fast leg sweeps create realistic directional motion blur and fabric wind-breaking sounds. Overall feels like a real person filming with a fixed mobile phone on-site, not CG or a commercial. [Character and Outfit Lock] The unique adult female lead is @1. Lock @1's face shape, features, skin tone, age, bone structure, and physique throughout; nine looks are always the same person. #1β#9 only provide clothing, do not refer to the model's face, hair, skin tone, and body: Look 1 wears #1... Look 2 wears #2... Look 9 wears #9. Clothing colors, styles, fabrics, cuts, and accessories strictly follow the corresponding numbers. [Scene] Simple indoor, light gray-beige walls and ceiling, a horizontal seam at the top. Light from ordinary top indoor lamps, slightly cool. No other people or clutter. [Camera A | 00:00β00:12.50] Camera fixed on the ground, lens center about 5cm from the ground, positioned 35cm directly in front of the female lead's standing position, aimed at the midline between feet. [Leg Sweep Blocking Rules] All leg outfit changes must be clearly presented: shift center of gravity -> obvious knee lift -> whole pant leg sweeps the lens -> 100% lens blockage for 3-5 frames -> hard cut -> new outfit same leg exits in the same direction -> natural foot landing. [Strict Storyboard] ... (detailed timing for nine outfits and prop interactions) ... [Camera B | 00:12.50β00:14.00] Hard cut to front eye close-up. Eye-level with @1, 30cm from face, using 35-50mm natural focal length. [Audio] No language or vocals throughout.
