The moves in RWBY fight scenes are primarily impossible to imitate by mocap because we just don't have the physical capabilities of doing that. Not even Olympians can do it.

That being said, the ones in V3E2... some of them are possible. Like Sage vs Tornado Girl, Neptune doing childish stuff, Wukong running... If you notice most of those moves are no longer the 'impossible' martial arts we've seen from previous Volumes, so, yeah. They may have used mocap to save time. In direct result there's an obvious drop in quality of the fights.
