Generate a 30-second photorealistic summer flash-mob music video in 4:3 landscape format, starting directly from the supplied opening frame. CONCEPT: Six original adult female performers turn an ordinary sunny city square into a cheerful dance performance. A parked yellow bus anchors the background. Colorfully dressed adult supporting dancers join behind them, while a few bystanders watch naturally. The visual energy comes from synchronized choreography, friendly expressions, flowing camera movement, and the contrast between coordinated performance outfits and the real city environment. CHARACTER CONTINUITY: Keep the same six leads throughout: LENA — blond hair, white headband, white collared top. ARIA — dark hair with pale face-framing streaks, gold top. MIKA — chestnut hair with bangs and white clips, white top. SENA — copper-brown hair, gold top. YUNA — long dark waves, white top. NOA — long black hair, gold top and gold leggings. Preserve their faces, hairstyles, relative heights, skirts, socks, and shoes. The same supporting ensemble remains behind them in consistent clothing. Distinguish the leads clearly from supporting dancers and distant bystanders. LOCATION: The same European square throughout: stone paving, leafy trees, pastel buildings, overhead tram wires, parked yellow bus, and an ice-cream cart near the edge of the square. The bus remains stationary. No traffic enters the dance space. CAMERA: Use smooth gimbal movement with the natural weight of a real camera operator. Start near the bus doorway, retreat onto the plaza, and establish the group before moving closer for member highlights. Maintain the bus behind the performers and preserve consistent screen direction. Use medium close-ups during stationary gestures and full-body views during traveling footwork. Cuts should land on completed dance accents and continue from matching body positions. 0–4 SECONDS — OUT OF THE BUS: Continue exactly from the first frame. LENA completes her step onto the pavement, lowers her open arms into the first beat, and makes two light walking steps toward the group. The other five move a short distance outward to establish their formation. The camera glides backward at a matching pace, revealing more of the square. Supporting dancers begin a simple groove near the bus. 4–9 SECONDS — FIRST GROUP PHRASE: Settle into a full-body wide shot. The six leads form a shallow staggered arrangement with clear gaps. They perform two side steps, a soft knee bounce, a diagonal arm reach, and a coordinated shoulder accent. Their pleated skirts and hair respond naturally to the movement. The supporting dancers echo the rhythm behind them without crossing the foreground formation. 9–13 SECONDS — BLOND LEAD HIGHLIGHT: Move smoothly into a medium shot of LENA as she completes a curved arm sweep above her head and brings the opposite hand near her cheek. She turns her shoulders toward the lens, smiles, and releases the gesture outward. Keep her face and white headband stable. The other members continue a simple in-place step pattern behind her. Pull back before she rejoins the full arm phrase. 13–17 SECONDS — GOLD-TOP CENTER: Cut on the outward hand motion to ARIA completing the same gesture. She takes one short step forward for her highlight while LENA shifts half a step back. ARIA performs a chest-level hand sweep, a light shoulder turn, and an upward arm line. The camera tracks gently sideways, revealing MIKA and SENA beside her. Keep their spacing readable and their movements connected. 17–21 SECONDS — THE SQUARE JOINS IN: Return to a wide view from near the ice-cream cart. Let a small part of its canopy frame the upper corner without blocking the dancers. The supporting ensemble opens into a broader rear arc. The six leads continue the choreography in front: alternating heel lifts, compact elbow accents, and a synchronized hand opening. A vendor and two distant onlookers smile or move slightly to the beat. Their reactions remain brief and natural. Keep the six leads as the clear focus. 21–27 SECONDS — FULL CHORUS: Use a smooth lateral camera move across a full-body group view. The leads perform a more energetic phrase: two diagonal step-touches, forearms crossing at chest level, arms opening outward, a controlled quarter-turn, and a return to face camera. Allow only short, assigned movement paths through open spaces. No one passes directly in front of another. The supporting ensemble follows a simpler version of the phrase in the rear. Catch small spontaneous smiles between members while preserving strong synchronization. 27–30 SECONDS — SUMMER FINISH: Ease back into a balanced wide composition showing the six leads, supporting dancers, yellow bus, trees, and pastel architecture. The group completes one final outward arm sweep and lands in a relaxed, coordinated pose. Hold briefly, then let their expressions soften into smiles and a little shared laughter. End with the full group visible and the bus still parked behind them. PHOTOGRAPHIC REALISM: Bright natural sunlight, detailed skin, realistic shadows beneath shoes, subtle perspiration, fine flyaway hairs, and credible fabric movement. Gold tops reflect the surroundings without glowing. White clothing retains texture. Keep architecture, paving, and bus geometry stable. MOTION: Normal-speed choreography, believable weight shifts, accurate foot contact, controlled turns, and smooth movement recovery. Keep faces sharp enough to recognize during motion, with restrained natural blur. AUDIO: An original upbeat summer pop instrumental with crisp percussion and a bright melodic hook. Include faint city ambience and light shoe sounds. No recognizable lyrics, narration, or subtitles. Avoid duplicated leads, merged bodies, sliding feet, changing hairstyles, sudden costume changes, unstable bus doors, moving background architecture, excessive camera shake, slow motion, artificial glow, text overlays, logos, and watermarks.
