Hop Hop Hop AI Dance：两张照片怎么做（以及为什么换位会失败）

Replace the man in the white jacket with the person from Image 1, and replace the man in the black jacket with the person from Image 2. Keep each person's face, hairstyle and outfit exactly as in their reference image. Keep the original video's motion, timing, camera movement, background and lighting unchanged. Each person stays in the same position and does the same actions as the man they replace.

Replace the characters in every frame of the entire video. Image 1 replaces the character wearing the white coat. Image 2 replaces the character wearing the black coat. This mapping stays fixed for the whole video. In the second half, the two characters swap positions. After the swap: - the character in the white coat is still Image 1, - the character in the black coat is still Image 2. Keep the original motion, timing, camera movement, background and lighting unchanged. In every frame, each character's face and outfit match their own reference image. No original faces, no blended faces, no identity swapping between the two characters.

Replace the two people in this video for the entire clip, every frame. Image 1 replaces the man: black zip-up hoodie with a large cross print, black baggy pants with chains, dark shaggy hair. Image 2 replaces the woman: purple-and-black striped sweater, black pleated skirt, fishnet tights, long black-and-purple hair. Identify each person by their outfit, not by their position. At the start the woman is in the foreground and the man dances in the background. Around the middle they swap: the man moves to the foreground close-up and the woman goes to the background. After the swap the man is still Image 1 and the woman is still Image 2. Keep the original dance moves, timing, camera framing, room, background and lighting unchanged. Each person's face, hair and body match their reference image in every frame, including close-ups and the moment of the swap. No original faces, no blended faces, no swapping identities between the two people.
