Rants Definitions Definitions aren't trivial. While a motion capture specialist can incorporate the product of those skill sets and use them as assets in the generation of CGI, none of the skills that distinguish the craft of animator are employed, nor even desirable in the motion capture pipeline. Even an animator donning a motion rig and dancing around is not animating, any more than an actor whose filmed motion will be traced by artists can be said to be a rotoscoper. I wonder who will challenge my assertion that motion capture and animation are mutually exclusive strategies.
Animation transcends the merely real.
If motion capture can handle the job, then my animation skills are not required for your project, thanks for not wasting my time. Only so much can be done in real time. There is an advantage to working outside of time, between the frames, where every frame, every pixel makes a difference. The definitions of principles that elevate animation from mere movement are painfully obvious when absent. The definitions aren't secret, and nobody made them up arbitrarily.
