ROTU just had the most amazing first couple days of motion capture sessions, with remarkable talent, and overall it was a huge success, though we learned so much during the process, so here are a few tips:
The main piece of advice we got beforehand was to prepare - That means we got as organized as possible, knew exactly what we were shooting and in what order, and what everyone’s job was on set. All the technology was synced, tested, and set-up properly before we got going with any shooting. There was only ever one person at a time giving direction, and everyone was focused and quiet on set when needed.
Make use of animation - Almost everything we shot with our actors was already mostly animated and designed ahead of time. We already knew what we wanted and how it was mostly going to look. That means we didn’t waste time capturing things that might not have worked, and ensured that we wasted as little time as possible.
Actors don't need mocap experience - To be fully transparent, there was a slight worry that our talent hadn't done mocap before which would get in the way of capturing the best performances. However, we can happily say that was absolutely not the case, and every actor and actress exceeded all expectations.
Make use of props - They not only help talent get into character but can help you shoot things that would be difficult to capture otherwise. We have spectacular mocap of Taiko master Isaku Kageyama, who was hitting actual Taikos. There was also a very useful animal prop that we had an actor mount, and a rein that our director held on one end and the actor held on the other end. The realism to the motion capture this added was invaluable
