Hyper-Realistic Animated Family Portrait Video

Generate a hyper-realistic 6-second video featuring the couple from the reference image, standing indoors in the same pose and lighting. Keep their physical features, skin tones, facial expressions, clothing, and hairstyle completely unchanged from the original photo. By second 1.5, a young girl aged 3–4 years, who resembles them genetically, enters the frame. She has a mix of their facial features — similar eye shape, skin tone, and smile — and interacts warmly with them (e.g., holds their hand, hugs them, or smiles at the camera). The atmosphere should be natural and joyful, reflecting a real-life family moment. Keep the background consistent with the original environment (indoor setting with soft lighting). No camera movement — use a fixed shot to preserve the realistic family vibe. Emphasize photorealism and emotional connection. The child must look like a natural daughter of the couple in terms of genetics and warmth.
