K-pop Flash Mob Music Video

Prompt

Landscape iPhone video, one unbroken 30-second take, no cuts. LOCATION / TIME Hongdae, Seoul, blue hour. The pavement is still wet from rain. Neon signage is just starting to come on. Use a long, straight stretch of shopfront-lined sidewalk with enough clear depth for the performer and camera to travel roughly 40 meters continuously. SOUNDTRACK This is a music video. The track is the entire audio. The music is NOT playing inside the scene. It is a finished studio recording laid directly over the footage in the edit, exactly like a professional music-video soundtrack. The music must be: - Clean - Loud - Full-range - Mastered - Immediate and front-of-mix - Filling the entire frequency spectrum, including deep sub frequencies Music style: K-pop dance-break instrumental at around 104 BPM. Musical elements: - Hard 808 sub - Tight, snappy claps - Sparse minor-key synth stabs - Layered female vocal ad-libs - Stacked vocal hooks with no intelligible words Energy progression: The track begins sparse and restrained, then transitions into a full drop that carries the entire second half. IMPORTANT AUDIO RESTRICTIONS: NO street ambience. NO traffic noise. NO footsteps. NO crowd noise. NO voices. NO wind. NO environmental sound. NO room reverb. NO outdoor echo on the music. The soundtrack must NOT sound like: - A phone speaker - A car stereo - A busking speaker - Music playing from a nearby store - Music heard from across the street No muffling. No distance effect. No bandpass filtering. The music must remain studio-clean, full-frequency, loud, and immediate throughout. THE PERFORMER A Korean woman in her early twenties. Appearance: - High ponytail - Oversized varsity jacket - Cropped tee underneath - Wide black trousers - Chunky sneakers She is a professional working music-video dancer and immediately reads as one through her movement quality. She travels forward for the ENTIRE 30-second take. She dances for the ENTIRE 30-second take. The forward walk itself is choreography. Walking is never used as a break between dance phrases. Movement vocabulary: - Hip-hop bounce with strong, visible knee action - Chest isolations - Rib isolations - Shoulder pops - Waacking arm circles - Sharp wrist snaps - K-pop point-choreography accents - Quick heel-toe footwork incorporated into her traveling steps Movement density: Maintain roughly 4 to 6 clearly visible choreographic accents per second. The movement remains sustained throughout. She NEVER drops into ordinary walking. Every accent should feel rhythmically connected to the soundtrack. Her movement amplitude follows the music: - Smaller and more contained during the sparse opening - Increasingly confident as the track builds - Biggest and most explosive during the final drop Performance behavior: She occasionally half-sings along to the track without producing audible diegetic vocals. She catches the camera lens, grins, breaks eye contact naturally, then reconnects with the lens. She feels confident, playful, spontaneous, and extremely comfortable performing directly to camera. THE CAMERA Handheld iPhone footage. Landscape orientation. One continuous 30-second shot. NO cuts. The camera operator walks backward ahead of the performer for the entire take, matching her forward pace. Camera height: Approximately chest height. Framing: Keep her centered and framed from head to sneakers for most of the take. Use a wide iPhone lens perspective. She must remain large enough in the frame that: - Her face stays clearly resolved - Her eyes remain readable - Her hands remain clearly visible - Her dance details remain easy to understand Camera behavior should feel authentically handheld: - Mild natural hand movement - Slight rolling-shutter wobble - Small framing imperfections - Autofocus hunts once or twice - Exposure subtly adjusts as she passes bright storefronts Wet pavement and asphalt reflect the neon signage and surrounding lights. DO NOT use: - Gimbal smoothness - Orbiting camera movement - Zooms - Camera rotation - Slow motion - Drone shots - Stabilized cinematic tracking CROWD BUILD 0-4 SECONDS The performer dances forward alone. Ordinary pedestrians are already moving naturally through the background and around her. Nobody appears to know what is about to happen. 4-9 SECONDS One guy who is already visible behind her begins catching the groove. He starts copying her shoulder choreography approximately half a beat late. His participation should initially feel accidental rather than staged. 9-15 SECONDS Three or four additional people gradually join. Each dancer must peel naturally out of the existing pedestrian flow. Entrances can come from: - The left side of the sidewalk - A visible shopfront - Further behind the performer - Other positions already established within the shot Nobody should suddenly materialize or enter from an impossible location. Each person was already somewhere logically present within the continuous environment. 15-21 SECONDS The group grows to approximately 12 to 15 dancers behind her. They remain loosely packed rather than forming a perfect formation. They copy her accents with slight ripple delays. The timing differences should make the sequence feel spontaneous and contagious rather than perfectly rehearsed. 21-30 SECONDS The number of dancers now HOLDS. Do not keep adding more people. Instead, increase the energy. The group gradually tightens into a loose wedge formation behind the lead performer. Choreographic intensity reaches its peak. The lead performer remains the unmistakable visual focus. FINAL 2 SECONDS She throws her hardest, sharpest choreographic accent directly toward the camera lens. Everyone behind her lands the same beat with her. The movement hits hard and feels satisfying. The shot does NOT freeze. The dancers remain physically alive after the accent. Bodies continue breathing and settling naturally as the 30-second frame ends. BACKGROUND PEDESTRIANS Some pedestrians NEVER join the choreography. They continue walking normally around the dancers. Their reactions vary naturally: - Slightly annoyed - Curious - Amused - Indifferent Some carefully edge around the growing dance group while continuing toward their destination. This contrast between dancers and uninvolved pedestrians is essential for making the moment feel real. PHYSICAL REALISM Grounded human biomechanics throughout. Every movement must show: - Visible weight transfer - Proper foot planting - Real momentum - Believable balance - Natural joint articulation - Correct body mechanics No sliding feet. No floating. No impossible limb motion. No rubbery joints. No unnatural acceleration. No teleporting people. No duplicated pedestrians. The lead performer stays the clear focus throughout the entire take. Maintain enough proximity and image clarity that her face, hands, expressions, clothing, and choreography stay clearly resolved even with the wide lens.
