Explore how to set up markers for custom geometry tracking so you can easily track objects in your green screen footage.<\/span><\/h2>\n\n\n\n

As a 3D artist, I’ve always been passionate about live-action movies. In this case, the actors are real, while the rest is almost 98% CGI. The actors perform on digital backgrounds<\/a> during the video shoots, surrounded by 3D props.<\/p>\n\n\n\n

If you ever watch behind-the-scenes documentaries<\/a> and footage, you’ll see giant green screens with tracking markers. It’s commonplace to see flying actors supported by wires\u2014for action sequences\u2014and even physical assets in some parts of the shooting location.<\/p>\n\n\n\n

It’s so exciting to understand these techniques applied to the film industry! Although your budget<\/a> might not be comparable to that of a major studio, it’s not a big deal. You can always learn to apply the same principles by producing professional shots and executing some simple 3D techniques.<\/p>\n\n\n\n

The Jungle Book<\/em> by Walt Disney pictures makes the protagonist live inside a tremendous 3D environment. Because of the jungle colors, the actor playing Mowgli constantly performs in front of a blue screen and not a green. The match and the integration are fantastic.<\/p>\n\n\n\n

The technique involved is called camera tracking. When the camera moves, the static 3D elements must maintain their location as if they were part of the actual video shoot. <\/p>\n\n\n\n
