A realistic cinematic city street scene at night. The camera is completely static and does not move at all, like a tripod shot. Cars and traffic are naturally driving past in the background. People walking on the sidewalk, city lights glowing. In the center there is a large LED billboard screen, completely blank with no text or letters. The billboard only shows an empty glowing screen. No camera movement, no zoom, no pan. Only the vehicles and city life are moving. Ultra realistic, high resolution, cinematic lighting, 10 seconds.
