Replace the **man in the original video** with the **uploaded person** while **preserving everything else exactly the same**.
Use the uploaded image only as the **identity reference**. Preserve the uploaded person’s **facial features, gender traits, face shape, eyes, eyebrows, nose, lips, skin tone, hairstyle characteristics, and overall recognizable appearance**. Adapt the replacement naturally so the final character clearly looks like the uploaded person.
Keep **all other elements of the original video unchanged**, including:
* body movement and proportions
* clothing and accessories
* pose and gestures
* facial expression timing
* head movement and eye direction
* camera angle and framing
* camera movement
* background and environment
* lighting, shadows, and color tone
* video speed and duration
* all props, objects, and other scene details
* all visual effects and the original overall mood
Track the replacement accurately throughout the full video, including head turns, side angles, expression changes, motion blur, and brief occlusions.
The replaced person should blend seamlessly into the original footage, with realistic skin texture, perspective, lighting, and movement. The result should feel like the uploaded person was the one originally filmed in the scene.
Avoid:
* identity drift
* flickering
* warped facial features
* mismatched skin tone
* unnatural face edges
* distortion during motion
* changing the background, props, or camera behavior
