Great video. He did reply to a thread on the Black Diamond website that may answer some of your questions, quoted here ( and linked here) :
"In response to a few of the questions:
The helmet cam I used to shoot this is the "Contour HD" by a Seattle company called "VHoldr."
The rope is the "6mm Alpine Personal Escape Rope," by Esprit Ropes in Toronto. It is an excellent rap/tag line I think. No special core - all nylon. It has a burly sheath. It is quite stiff, which is always a plus in super skinny ropes, because the stiff rap lines tangle less.
The gloves are indeed the Torque Gloves - not super warm, but great dexterity. I had a pair of Punisher gloves in my jacket in case it got colder, but never had to use them.
As for the one pitch where I belayed, it is a rudimentary technique, that in Yosemite is often referred to as "back-looping." The idea is to build a multi-directional anchor at the base of the questionable terrain, thread your rope through this anchor, attach yourself to both strands of the rope (whether with knots, hitches, or devices), and climb up, risking a factor 2 fall onto your anchor. The advantage over a traditional self-belay is that you can simply pull your rope up from above afterwards, rather than having to rappel down and prusik back up. If you are descending the same route that you are climbing (such as I was in this video), then you can clip both strands through intermediate pieces of protection (such as the cams I was placing in this video), because you know that you can retrieve them on your descent, to negate the possibility of taking a factor 2 fall. And just to be clear - this is NOT a safe, or accepted technique for self-belaying - it is a technique that I chose to use on a section of climbing that was only just barely hard enough that I wasn't comfortable free-soloing it. It is still "sketchy," and a guaranteed way to fail your UIAGM alpine exam!
