wan/3-0-video プロンプト - 動きに溶け込む自然な顔交換

Replace the person in the reference video with the person from the reference image. Keep the original motion, pose, expression timing, camera movement, framing, lighting, and background exactly the same. Preserve the reference person's facial features, face shape, hairstyle, skin tone, and outfit, and blend them naturally into the scene's lighting and color grading. Clean edges, no flickering or distortion, and a stable, consistent face throughout the video.
