怎么和两个朋友做 No Scrubs AI 视频（不串脸）

Replace the 3 people in the source video with the 3 people from the reference images. Copy each person's face, hair (style, color, length), skin tone, body type, outfit and shoes exactly from their own photo, in every shot, also in close-ups. 3 different real people, never mix their looks. Ignore the background and lighting of the reference photos. Do NOT keep the source people's look: no blonde buzz cut, earrings, cream sweater or black wide trousers (center); no long dark braid, olive bomber jacket, white tank or light-blue jeans (left); no black curly hair, yellow striped track jacket or black cargo pants (right) — unless shown in their own photo. Baggy clothes stay baggy, jackets stay jackets. Hair moves naturally. Keep the source motion, choreography, timing, camera moves, framing, cuts and lighting exactly. Real-time speed, no slow motion, no speed-up. 14.00 s long. LIP-SYNC: music video, they sing along. Copy the source mouth frame by frame: jaw opens on vowels, lips close on m/b/p, no frozen smile, no delay. A sings in shots 1 and 7, B in shot 11; in group shots all three mouth the words. Natural blinks. 12 SHOTS, hard cuts at 1.79, 2.54, 4.38, 4.88, 6.54, 7.50, 9.38, 10.75, 11.33, 12.71, 13.88 s, no new cuts: 1 (0-1.79): close-up of A's head and shoulders, pale blue-grey background, singing, hands at frame edges, ends pointing a finger at the camera. 2 (1.79-2.54): wide front shot of the white studio: B left, A center, C right, bent knees, swinging arms. 3 (2.54-4.38): low tilted shot: A center waving one arm high, C close on the right, B partly on the far left. 4 (4.38-4.88): wide front, all three in a row stepping in sync. 5 (4.88-6.54): tilted side wide shot: B jumps with arms overhead, A and C dance on the right. 6 (6.54-7.50): low medium-wide: B left, A center, C right, arm moves in front of the chest. 7 (7.50-9.38): top-down into a narrow metal corridor: A alone, arms to the side walls, looking up, singing. 8 (9.38-10.75): low wide: A center, B left, C right, leaning and dancing. 9 (10.75-11.33): medium front: all three step toward the camera. 10 (11.33-12.71): wide front: A balances on one leg, B and C lean and jump. 11 (12.71-13.88): extreme close-up of B's face, plain white background, singing, open hand by the face. 12 (13.88-14.00): low medium-wide: A center, hand at the head, B and C dancing. WHO IS WHO: A = IMAGE 1, replaces the center person: lead singer, center of group shots, alone in the corridor and first close-up. B = IMAGE 2, replaces the left person, singer in the white close-up. C = IMAGE 3, replaces the right person. LOCATION unchanged: white futuristic studio, glossy white tiled floor, curved silver wall panels with the same large silver 3D letters; brushed steel corridor; white background in the close-up. No props. Only these 3 people, nothing in their hands. Five fingers per hand. No text, subtitles or watermark.
