Replace only the woman in the yellow shirt behind the cake in <Video 1> with the young woman in <Picture 1>, her face as in <Picture 2>. She smiles proudly at the berry cake on its stand, turns it gently, then looks up at the camera and says the spoken line in the soundtrack, her lips matching the words in the soundtrack. 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.
