10–14s — 菱形队形 → 水平直线队形
流畅地以半步完成转换，MINA 从 RINA 身后走出，完整进入视野。队形稳定后，进行手腕弹动、手臂横扫、髋部重拍动作和脚尖点地。

30-SECOND K-POP PUBLIC DANCE COVER — SHIBUYA, TOKYO (with synced typography)
Generate a 30-second horizontal 4:3 realistic live-action K-pop girl group public dance cover video, using the provided first frame as the exact visual starting point, with retro bold-typography captions appearing in sync with the choreography, styled like halftone poster-text overlays (bold condensed display font, high-contrast color against the scene, subtle grain texture matching the background).
TYPOGRAPHY STYLE
Font: bold condensed display, poster-style
Placement: upper third or side margin, never covering faces or hands
Animation: quick fade/slide-in synced to the beat, holds for its duration, clean fade-out before the next line
Color: high-contrast against Tokyo evening tones (cream/gold/white lettering with soft drop shadow)
One line active on screen at a time
SCENE & LOCATION
Shibuya street, Tokyo, Japan, natural evening light, authentic public dance-cover environment — kanji/hiragana/katakana shop signs, convenience stores, cafés, boutiques, vending machines, parked bicycles, overhead wires, glass reflections, soft neon beginning to glow, blurred distant pedestrians. No recognizable logos or brand signage.
FRAME & CAMERA
Horizontal 4:3, fixed frontal camera, eye-level, ~5 meters distance, full-body framing, stable documentary style. Subtle push-in only during RINA's highlight, then returns to full frame. No cuts, rotation, extreme zooms, or handheld shake.
CHARACTERS — EXACTLY 4 DANCERS
RINA (center): long straight black hair, babypink cropped racing jacket, ivory crop top, charcoal cargo shorts, brown ankle boots
YERI (left): light brown high ponytail, light blue cropped knit jacket, beige camisole, faded black wide-leg jeans, cream sneakers
SOO (right): silver-grey hair, navy off-shoulder top, rose-gold waist chain, charcoal pleated skirt, black platform shoes
MINA (back): dark reddish-brown curly hair, olive bomber jacket, grey crop tee, navy straight-leg pants, off-white platform sneakers
No fifth dancer, no duplicates, no overlapping bodies, no identity swaps.
TIMELINE WITH SYNCED TYPOGRAPHY
0–6s — OPENING DIAMOND
RINA center-front, YERI front-left, SOO front-right, MINA back-center. Hand opening, side steps, shoulder rhythms, crossed-arm accents, face-framing gestures, hip accents.
Caption: "SAME STREET, NEW BEAT" — fades in at 1s, holds to 5s, fades out.
6–10s — RINA HIGHLIGHT
RINA: chest pop, head tilt, direct eye contact, finger point to camera. Others restrained, framing her. Subtle push-in then return.
Caption: "ALL EYES, ONE GIRL"* — appears exactly as RINA points at camera (6.5s), holds through push-in, fades by 9.5s.
10–14s — DIAMOND → HORIZONTAL LINE
Smooth half-step transitions, MINA steps out from behind RINA into full visibility. Wrist flicks, arm sweeps, hip accents, toe taps once stabilized.
Caption: "SHIFT THE SHAPE" — slides in as formation begins moving (10s), fades out once line stabilizes (13.5s).
14–19s — HORIZONTAL LINE CHORUS
Heel-toe shuffles, knee bounces, chest pops, shoulder rhythms, toe taps. SOO performs controlled body-wave highlight on the right.
Caption: "WAVE IT OUT" — appears as SOO's body-wave begins (15s), fades before formation shifts (18.5s).
19–23s — RETURN TO DIAMOND + RIPPLE
Diamond reforms, MINA repositions opposite RINA, fully visible. YERI initiates ripple body wave: YERI → RINA → SOO → MINA.
Caption: "RIPPLE THROUGH" — timed to appear exactly as the ripple starts at YERI (20s), fades as it reaches MINA (22.5s).
23–27s — FINAL CHORUS
Upward arm points, hip accents, shoulder rhythms, toe taps, chest pops, rising energy, natural hair/clothing movement.
Caption: "TURN IT UP" — appears on the first upward arm point (23.5s), fades before final transition (26.5s).
27–30s — FINAL V FORMATION + FREEZE
RINA front-middle, YERI back-left, SOO back-right, MINA mid-back-right. Coordinated freeze pose, symmetrical arm lines, feet planted, completely still for the final second.
Caption: "FREEZE FRAME" — slides in as the freeze locks (28s), holds steady and crisp through the final loop-ready frame (30s) — no fade-out, ends on screen.
VISUAL STYLE
Realistic live-action street photography — genuine skin texture, individual hair strands, realistic clothing materials, accurate body proportions, natural shadows, evening illumination, storefront reflections, documentary cinematic composition. Typography sits as a poster-style overlay layer, not baked into the environment — legible, clean, and non-intrusive to the dancers.
STRICT NEGATIVE REQUIREMENTS
No anime, cartoon, 3D/CGI look, stage lights, studio set, extra dancers, duplicated people, overlapping bodies, distorted anatomy/hands/feet, teleportation, sudden formation changes, rapid camera movement, camera rotation, extreme zoom, watermarks, subtitles unrelated to the timed captions, or recognizable copyrighted logos/signage. Captions must stay legible and never obscure faces or hands.
FINAL OUTPUT
30 seconds, horizontal 4:3, realistic live-action K-pop public dance cover, Shibuya street, Tokyo, exactly 4 consistent dancers, full-body frontal camera, three formations, synchronized choreography with six timed typography captions matching each beat, stable camera, natural evening lighting, c建议模型
