On-set virtual production is a new way of making movies and TV shows. Instead of building physical sets and using big cameras and lots of people to film a scene, virtual production uses big computers and monitors to create a virtual world. It looks like a movie or TV show, but it's all done through a computer. Using special software, filmmakers can design the sets, control the lighting, design the cameras, and create special effects like explosions and flying cars. Then, they record the actors in front of a green screen and add them into the virtual world. It's a faster, cheaper, and easier way of making movies and TV shows.
