A person on Github converted all the CMU motion files to a newer BVH model than the old BVH model. 
It gives you a head start with a more upright T Pose to work with. The files are named so you do not need a text file for the motions.
The motions play faster than the originals. But in IC, you can slow down the motion and collect clip.
Some of the motions are still wonky. But those of you who want to try, you can download the files from Github.
I hope this helps some of you to get some free motions. I thank God for helping me find these.
The file is about 1.8 GB to download, because there are some c3d motion files.
