Photorealistic live-action music video footage. <Picture 1> is the artist: keep her exact face and hairstyle. Scene: a mirrored elevator interior with warm downlight. She wears a deep red satin slip dress. Action: she is climbing stairs, singing to the camera, head bobbing on every beat. Camera: three-quarter view, locked-off static, shallow depth of field. Do not generate: no outfit change, no text, no watermark, no extra limbs, no distorted hands, no duplicate person, no blurry face.
