Female Character Swap Full Video Prompt

The Genius Prompt

Use the provided video as the source footage and the generated female character reference sheet as the identity reference. Replace the original male person with the female character from the reference sheet.

1. Character identity
The replacement character must be the exact same young woman shown in the character reference sheet. Maintain consistent facial features, face shape, large dark brown eyes, natural eyebrows, soft rosy cheeks, subtle nose, natural pink lips, long black hair, and overall appearance.
Her hairstyle should remain long, naturally flowing black hair with soft face-framing strands and a half-up hairstyle. She must wear the same cream-white sleeveless floral sundress with delicate blue flowers, thin straps, lace-trimmed neckline, and front tie detail shown in the reference sheet.
Preserve the character's identity throughout every frame. Do not blend her face with the original person or generate a different face.
2. Preserve the original footage
Keep the original video composition, camera perspective, framing, background, furniture, chair, walls, ceiling, and ambient lighting unchanged.
Retain the original seated position and body orientation. The character should occupy the same position and approximate screen-space size as the original person, with realistic body proportions and natural anatomy.
Recreate the original pose as closely as possible: seated in the black office chair, torso slightly leaning back, head tilted subtly to one side, one arm raised with the index finger pointing upward, and the other arm resting naturally near the body.
Translate the original person's gestures into anatomically natural movements for the female character. Preserve the timing, direction, and speed of all movements from the source video.
3. Facial expression and motion
Give the character a relaxed, confident, slightly playful expression with gently closed lips and a subtle smile. Maintain natural eye direction and realistic blinking.
Her facial expressions must respond naturally to the original footage. Preserve head turns, subtle posture changes, shoulder movements, hand gestures, and body movement without introducing additional actions.
Ensure accurate facial tracking, consistent eye placement, stable hair shape, realistic skin texture, and natural transitions between frames.
4. Lighting and visual style
Match the source video's original indoor lighting, exposure, shadows, white balance, and muted neutral color palette.
Create a photorealistic live-action result with natural skin texture, realistic hair strands, accurate fabric folds, and physically plausible shadows. The character must appear genuinely present in the original room rather than pasted onto the footage.
Maintain consistent lighting across the face, neck, arms, and clothing. Avoid excessive skin smoothing, artificial beauty filters, cartoon-like features, or overly glossy skin.
5. Video consistency
Maintain the same camera angle, perspective, focal appearance, and framing as the source video. Preserve the original video duration, movement timing, and background details.
Prevent flickering, face morphing, identity drift, inconsistent clothing patterns, distorted hands, extra fingers, unnatural joints, floating objects, and sudden changes in body proportions.
Keep the same female character throughout the entire clip, including during movement and changes in facial expression.
6. Negative instructions
Do not retain the original male face, male hairstyle, glasses, T-shirt, wrist accessories, or other male-specific appearance details. Do not combine male and female facial features.
Do not change the room, camera position, chair, background, or lighting setup. Do not add new objects, people, gestures, text, or visual effects. Do not change the character's dress or hairstyle between frames.
FINAL RESULT: A seamless, photorealistic character replacement video in which the female character from the supplied reference sheet naturally performs the same actions as the original person, with stable identity, accurate motion, and the original environment preserved.
