mocap is really expansive. A mocap camara is aound 25k US. And you need at least 7 of them to capture anything. However, 7 cameras won't get you much freedom to capture all angles. Some studio has 14, some has 25. 25x25k=620k. Plus all the wires, room, computers, softwares and operating staff. Which is over 1mill US to own a mocap syetem.
After my college bought the mocap system, there has no body come in for support. We read the manuel by ourself. Starting frome setup to data retouch, all by manuel.
