   My exact prompt

   Preserved exactly as used. The template below is for your own character and scene.

   Replace only the person in the video with the young woman from the reference image, so she looks exactly like her photo in every frame: the same face shape, eyes, eyebrows, nose, lips, jawline, skin tone, hair and makeup, staying recognisably her even mid-expression, while talking, when turning her head, during fast movement and while eating; her face must be entirely her own and must not resemble the original man at all, with none of his face shape, jaw, cheeks, nose, eyes, brows, hairline, haircut, earrings or build; she is slender, with a slim face, narrow shoulders, slim arms and a feminine posture; she has clear, smooth skin with no moles, spots or marks anywhere on her face; match the original performance frame for frame, with the same body movements, head turns, eye movements, micro expressions, timing and lip movements, perfectly lip-synced to the original audio, including the fast movements and biting and chewing the food; keep the room, purple and warm lighting, wide-angle lens, camera position, framing and the food exactly as in the original; photorealistic phone footage with real skin texture, visible pores, natural skin shine, fine detail, realistic hair strands and natural light on her face, no smoothing, no beauty filter, no cinematic grading, no changes to anything other than the person.
