Use P1 as the source video and P2 as the identity reference for the replacement person.
Replace the main person in P1 with the person from P2, while keeping everything else exactly the same.
Main task
Preserve the original video structure, choreography, timing, pacing, camera angle, camera movement, background, lighting, styling, and overall atmosphere from P1.
Preserve the original dance movements exactly as in P1.
Preserve the original music and audio exactly as in P1. Do not change, remix, mute, or replace the soundtrack.
The final result should look like the person from P2 is the one originally performing in the video.
Identity replacement rules
Carefully analyze P2 and preserve the person’s:
facial features
hairstyle
skin tone
body proportions
overall identity and recognizable appearance
Integrate the person from P2 naturally into the full motion performance from P1.
Make the face consistent across all frames and all movements.
Ensure the replaced person looks stable and realistic from beginning to end.
Preserve from the original video
Keep the following unchanged from P1:
dance choreography
body motion rhythm
music / soundtrack
scene composition
background
camera movement
editing rhythm
lighting and color mood
outfit if needed for continuity, unless identity transfer requires minor adaptation
Quality requirements
Maintain realistic anatomy and clean motion.
Avoid face flicker, warping, drifting features, broken limbs, duplicate body parts, or unstable expressions.
Keep lip area natural even if the person is not speaking.
Make the motion smooth and believable during fast dance moves.
Ensure the head and face track correctly with the body throughout the performance.
Important restriction
Do not change the dance.
Do not change the music.
Do not change the timing.
Do not add extra people, text, effects, or transitions.
Only replace the main performer with the person from P2.
Remember that this is a template for changing clothing and makeup. The subject of P2 needs to change makeup, clothes, and hairstyle in the video. If you want to change your face, you have to change your clothes.
