Use the uploaded video as the base motion reference. Use P1 as the identity reference for the left person in the video, and use P2 as the identity reference for the right person in the video.
Replace the two people in the original video with the two uploaded people while keeping everything else the same:
P1 replaces the left person only
P2 replaces the right person only
preserve each person’s recognizable facial features, hairstyle, skin tone, age appearance, and overall identity
keep the original body positions, movements, timing, camera angle, scene composition, and background
keep the same actions, gestures, expressions, and interaction between the two people
keep the same outfit style if possible, but adapt the clothing naturally to fit P1 and P2
maintain realistic proportions, natural head movement, and accurate face tracking
ensure the face swap is stable in every frame
avoid face flickering, warping, identity mixing, or facial distortion
do not switch sides
do not merge the two identities
do not change the choreography or motion
do not alter the background or camera movement
Final result: a natural, realistic video where the left character is replaced by P1 and the right character is replaced by P2, while the original video’s motion and scene remain unchanged.
