Use P1 as the complete video reference and P2 as the only identity reference for the performer.
Replace the main K-pop idol appearing in P1 with the person from P2. Carefully analyze and preserve the person’s recognizable facial features, hairstyle, skin tone, age, gender presentation, and overall identity. The final performer must clearly look like the person in P2 throughout the entire video.
Keep everything else from P1 unchanged:
Same concert stage and venue
Same camera angles, framing, zooms, and camera movement
Same entrance timing and performance duration
Same choreography, gestures, walking path, body movement, and facial expressions
Same backup dancers, audience, lighting, LED screens, smoke, confetti, and stage effects
Same music, rhythm, pacing, and synchronization
Transform the person from P2 into a polished K-pop concert idol. Give them a professional stage-ready appearance with a stylish contemporary idol outfit that matches the visual concept, lighting, and color palette of P1. The outfit must remain consistent throughout the video and move naturally with the body.
The performer should enter and appear on stage exactly as the original idol does in P1, confidently greeting the audience and performing with strong stage presence, controlled expressions, natural lip movement, and realistic interaction with the crowd and camera.
Maintain accurate face tracking in every frame, including side profiles, close-ups, fast movements, hair motion, changing light, and partial occlusion. Preserve natural anatomy, realistic hands, stable facial proportions, and consistent clothing details.
Do not paste a flat face over the original performer. Fully reconstruct the performer using the identity from P2 so the face, head, neck, body, hair, costume, lighting, shadows, and motion appear naturally integrated into the concert footage.
No face flickering, identity drift, warped features, duplicated limbs, costume changes, robotic movement, floating body parts, mismatched skin tone, incorrect lip-sync, or changes to the original video composition.
