Hi Guys, Thanks for watching.
The camera looks smooth because it is a super wide angle shot and that minimized the effect of jarring. At the risk of seeming immodest, I have been told by many other riders that I am kinda smooth and steady on my bike. (I'm not a good stunt rider or a fast guy so it's nice to be good at something) I actually noticed when I put the camera on the "follow" bikers' handlebars or helmets that the shots were a lot more jittery.
The GoPro camera we were using is one of those popular small cameras that has a lot of convenient mounts available for it. For example, I had a helmet mount and a handle bar mount. The close up reverse shot was made a wooden stick strapped to my helmet like a boom. I mounted the camera upside down, and facing me, on the front end of the stick. I used a sock full of pennies as a cantilevered counter balance on the back part of the stick. Yes, it was a white sock. :-)
The "lock down shots", where we just rode thru the picture, were made by strapping the camera to trees when ever I thought the light was nice and the trail looked good. I used some large rubber coated wire twist ties that I bought at Home Depot recently to make tying the camera to the tree quick and easy.
The hardest part was trying to work when the light seemed consistent enough for shots gathered on different rides to seem to work together.
Stuff like that.
Thanks for watching!
