Replace only the woman on the sofa in <Video 1> with the young woman in <Picture 1>, her face as in <Picture 2>. She plays with the baby on the sofa, smiling. The baby stays exactly as in <Video 1>. Keep her identity, face, hair and outfit from <Picture 1> and <Picture 2>. Preserve the source video's camera, framing, background, lighting, objects, and all other people. Match the selected woman's position, scale, pose, and movement throughout the clip. Do not show the reference pictures or their grey background.
