Replace the main character in the uploaded video with the character from the uploaded reference image.
2
Use the reference image strictly as the identity and appearance reference for the new character. Preserve the character's face, hairstyle, skin tone, body proportions, clothing, and overall visual identity as accurately as possible.
Keep the original video exactly the same in terms of camera movement, framing, composition, background, environment, lighting, shadows, color grading, timing, pacing, and scene dynamics.
The replacement character must follow the exact movements, body position, gestures, facial expressions, eye direction, head movement, and interactions of the original main character throughout the entire video.
Maintain accurate body anatomy, realistic motion, natural facial expressions, consistent identity across every frame, and proper occlusion with objects and other characters.
Do not alter, remove, or regenerate any other character, object, background element, or visual detail in the video.
Only replace the original main character with the character from the reference image. Everything else must remain unchanged.
