I schlepped a camera on my 2009 thru hike to record a different Vidcast (see below, You're a Wimp!), but when I wasn't doing that I turned it on myself to chronicle how my trip was going whilst under locomotion. Sometimes great, sometimes not; I was not in good shape that year but, hey, how hard can it be? I've done it many times before. I supplement the yapping with some trail footage taken on my 2008 hike to give the viewer a break from my talking head. I include a map and elevation profile reference so the viewer can stay oriented as to where I am when I'm speaking. This used to be a paid product but I have retired it and made it available for general viewing.
This is the Vidcast I was working on during the same trip:
