wan/3-0-video プロンプト - 変わらない場面でのリアルな人物置換

Replace ONLY the selected person in the original video with the person shown in the uploaded reference photo. Use the reference photo as the strict identity and wardrobe guide. Preserve the exact facial structure, eyes, nose, lips, skin tone, age, hairstyle, and natural proportions. Keep the same clothing and accessories shown in the reference. Do not blend identities, beautity, or alter facial features. Precisely replicate the original character's performance, including body movements, hand gestures, head turns, eye direction, facial expressions, and lip movements, with identical timing and positioning. Preserve the original location, surrounding people, objects, lighting, shadows, camera movement, framing, focus, motion blur, and overall cinematic texture. Match the replacement naturally to the scene's lighting and perspective. Maintain realistic interactions and foreground occlusions when objects or people pass in front of the character. Keep the original video duration, speed, cuts, and audio completely unchanged, including dialogue, music, and ambient sounds. Do not generate a new voice.
