Family Portrait: Couple and Their Young Son

Create a hyper-realistic 6-second video of the same couple in the reference photo, without changing any of their physical features, sitting together in a warm, cozy home environment. At second 1.5, a 3-4-year-old girl enters the frame. She must have blended facial features inherited from both the man and the woman in the photo, resembling them as if she were their biological daughter. The child should have natural expressions, lively movements, and interact affectionately with the couple. Keep realistic lighting, detailed skin textures, natural hair, and authentic background depth. Maintain the couple’s exact appearance from the photo, with no changes to their facial structure, hairstyle, or clothing.
