One thing I noticed is that the depth of field is very small, which means that it was shot with a very large aperture camera, obviously not a typical head-mounted camera, which is little more than a webcam. This gentleman is using a large lens, and very possibly, a high shutter-speed, and high frame-rate as well. It probably uses on-board media, to avoid problems with the high frame rate. I'm only guessing; I'm too chicken to actually join the site, and see a full-length feature. You should be able to tell high frame-rate if the motion is smooth.
