Is there any resource on how to cleanup mocap data with Kinefx (without doing it manually)? Stabilise joint node seems to be the right place to start, but I found documentation is not really informative. Anyone has some resources or tutorials they could share?

Here is one I got a lot out of. This converts mocap data to simultaneous onion-skin style line rigs. Because each frame is made up of lines, you could use standard SOP tools to smooth or adjust them.
