Generate a 30-second horizontal 4:3 realistic K-pop public dance cover video from the provided first frame. Scene: A real Seoul street location at early evening, similar to Hongdae or Seongsu. Wide pedestrian street, clean grey pavement, Korean storefront signs, cafe windows, fashion shops, parked bicycles, street trees, warm shop lights, distant blurred pedestrians, realistic urban depth. The dance area is open and clear. Dancer count: The video must feature exactly 4 dancers from start to finish, no more and no fewer. The same 4 dancers remain visible throughout the video. Do not add extra dancers or background dancers. Distant pedestrians may appear only as blurred background. Dancers: MINJAE, male center lead, black cropped bomber jacket, white T-shirt, dark grey cargo pants, short black hair. SORA, female left-front dancer, light blue denim jacket, white T-shirt, black pleated skirt, long dark brown hair. JAE, male right-front dancer, oversized white open shirt, black inner top, black pants, ash-brown hair. RINA, female back-center dancer, soft pink jacket, grey T-shirt, dark denim shorts, short black bob hair. Character consistency: Keep all 4 dancers’ faces, hairstyles, outfits, body proportions, and roles consistent. Do not change clothing, faces, hairstyles, or number of dancers. Camera: Horizontal 4:3, front-facing camera, mostly fixed at eye level, full-body framing. All 4 dancers should remain clearly visible. Allow gentle stable camera movement: slight push-in during highlights and slight horizontal follow during formation changes. No fast cuts, no spinning, no heavy zoom, no shaky camera. Spacing rule: Keep clear spacing between the 4 dancers. RINA must remain slightly offset in the back so she is visible and not blocked. Avoid overlapping bodies. Formation changes should be small, clear, and readable. Each dancer moves only half-step to one step during transitions. Dance style: Realistic K-pop mixed-gender public dance cover. High synchronization, confident expressions, clean footwork, sharp shoulder hits, chest pops, face-frame gestures, wrist flicks, arm sweeps, hip accents, body waves, heel-toe shuffles, toe taps. Timing: 0s - 5s: Start in a wide diamond formation. MINJAE center front, SORA left-front, JAE right-front, RINA back-center slightly offset. All 4 open their hands from chest level, step slightly right, return center, cross arms, and hit face-frame gestures. Camera stays full-body. 5s - 8s: MINJAE performs the center killing part: chest pop, head tilt, direct eye contact, finger point toward camera. Other 3 dancers frame him from their positions. Camera gently pushes in, then returns to full-body. 8s - 12s: The group changes from diamond to short horizontal line. SORA moves half-step left, JAE moves half-step right, MINJAE moves half-step back, RINA moves half-step forward. No crossing paths. They perform wrist flicks, arm sweeps, hip accents, and toe taps. 12s - 15s: SORA performs a short left-side highlight: smooth body wave, playful hand point, confident expression. Other 3 maintain spacing and frame her with smaller arm gestures. Camera gives a brief subtle push-in. 15s - 19s: Group changes into a two-front two-back formation. MINJAE and SORA in front, JAE and RINA in back, all clearly visible. All 4 perform heel-toe shuffle, knee bounce, chest pop, and shoulder groove. 19s - 22s: JAE performs a right-side highlight with grounded footwork and a clean arm sweep. He stays on the right side and does not cross in front of others. Camera remains stable. 22s - 25s: RINA leads a ripple body wave from the back-center position. The ripple travels through MINJAE, SORA, and JAE. Everyone stays in place and remains visible. 25s - 28s: The group returns to a wide diamond formation. All 4 perform synchronized face-frame gestures, upward arm points, shoulder hits, hip accents, and toe taps. Each dancer steps half-step outward for a wider ending shape. 28s - 30s: Final pose. MINJAE stands center front, SORA left, JAE right, RINA back-center slightly offset and fully visible. All 4 face the camera with a clean symmetrical K-pop ending pose. Hold the final freeze for the last second. Motion quality: Realistic dance physics, grounded foot contact, natural hair and clothing movement, synchronized timing, clear silhouettes, stable faces, no motion smearing during formation changes. Final output: 30 seconds, horizontal 4:3, realistic mixed-gender K-pop public dance cover, real Seoul street, exactly 4 dancers, clear spacing, simple formation changes, gentle camera movement, no subtitles, no watermark.
