P1 is the fixed template video. P2 is the single user-uploaded image and may contain one person, a couple, or a group. Recreate P1 shot by shot and frame by frame. If P2 contains multiple people, map them consistently to P1's featured people from left to right and preserve each person's exact face, gender presentation, hairstyle, skin tone, age, and body identity. If P2 contains only one person, replace only P1's central or clearly featured lead and keep all supporting people from P1 unchanged. Never duplicate one P2 face across multiple people and never retain or blend the identity of any P1 person being replaced. Strictly preserve P1's number of people, relationships, poses, choreography, wardrobe or costumes, camera, composition, background, lighting, effects, transitions, timing, audio, music, sound effects, synchronization, and aspect ratio. Never use P2's background. Do not add people, remove people, swap identities between frames, add extra limbs, text, subtitles, logos, or unrelated props.
