Completely replace the original character in the reference video with the provided character reference. Preserve the reference video’s exact choreography, body movements, gestures, poses, timing, facial expressions, and performance frame by frame, with precise body tracking, natural motion, and stable anatomy throughout.

Seamlessly integrate the provided character as if they were present in the original footage from the beginning, with physically accurate lighting response, realistic contact shadows, occlusion, reflections where applicable, and consistent motion blur. Use the exact clothing and outfit design from the original character in the reference video: identical garment types, materials, colors, textures, patterns, proportions, accessories, folds, and realistic fabric physics. Completely remove any hat or headwear. The character must be naturally bareheaded, showing the provided character’s original hairstyle and head appearance. Keep the uploaded character’s face exactly matching the provided reference, unchanged: preserve exact identity, facial structure, age, skin tone, natural skin texture and pores, hairstyle, body proportions, recognizable features, and natural expressions. Do not beautify, stylize, reshape, redesign, or alter the face in any way. Maintain stable facial identity in every frame. No hat, no headwear, no identity drift, no character morphing, no outfit redesign, no extra accessories, no additional characters, no background or prop changes, no camera changes, no flickering, no warping, no distorted hands, no distorted face, no visual artifacts.
