Replace only the woman in the grey cardigan who walks in in <Video 1> with the young woman in <Picture 1>, her face as in <Picture 2>. She arrives at the Christmas dinner, pulls out a chair and sits down at the table, smiling at everyone. Everyone else 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.
