So with all these cameras, the more cameras you have, the higher fidelity you get?

Yeah, the more coverage you get, the less likely you're going to have occlusion from markers. Occlusion is when a marker that's on the actor gets hidden from the cameras and the camera can't see it. Then you have to go in and you have to fill in those little gaps. Let's say an actor's rolling around on the floor or something. The better coverage you have, the better the data's going to be, quicker to clean up.
