I decided that I wanted to gain some more knowledge about mocap animation and learn about the animation process in motion builder.  To start my journey on learning more about this area, I started simple with just a basic walk and idle animation.  I'm starting these animation off separately before I combine them into one.  While I was in grad school,  I went to some of the lectures about mocap animation.  I never got to finish any of the animations but I did learn a lot from my professor.  

To start off, I found my mocap data from the animation I started in grad school.  I'm starting from the very beginning where I have to clean and characterize the data.  I see many red dots in the scene which is data I need to clean.

To begin cleaning the scene, I first start with opening the schematic.  I deleted the system, unlabeled markers, markers for props that were not used, and the markers that were on the actor.

To take the cleaning process a bit further, I characterized the scene.  Characterizing allows me to label the joints to transfer the data to a mocap rig.  I first set the starting frame at 0.  I also zero out all of the rotations.  I then selected just the hip joint and rotated the X 90 degrees. Next selected everything and keyed it on frame 0.  Finally, added a template character and renamed it Mocap so I know what the mocap data is.  At this point I save my cleaned file in a new folder.

I then run through this very same process for my idle animation.
