Replace only the woman with curly blonde hair sitting on the floor in <Video 1> with the young woman in <Picture 1>, her face as in <Picture 2>. Sitting by the Christmas tree, she shows the boy his present and they laugh together. The red-haired boy 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.
