Replace only the woman sewing at the machine in <Video 1> with the young woman in <Picture 1>, her face as in <Picture 2>. Under the desk lamp, she feeds fabric through the sewing machine, concentrating. The blue wall behind her 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.
