Replace only the woman behind the cake in <Video 1> with the young woman in <Picture 1>, her face as in <Picture 2>. She smiles proudly at the finished berry cake on its stand and turns it gently with her hands. 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.
