I have a Drift 1080 HD as well, Although I only ever use it at 720.
As at 720 there’s less of a fisheye effect and you can run it at 60 frames per second, Better if you want to view in slow motion.
Although as said above it really does make stuff look a lot more tame on playback, as you are generally looking in the direction you are going so it Makes it difficult to appreciate the steepness of the trail.
So when I do see head cam footage that looks steep, I think to myself that must be bloody steep.
I have never actually recorded anything that I have considered worthy of YouTube and every thing normally gets deleted after disappointingly viewing how unGnarr I am.
Even makes my crashes look far less spectacular than they appear at the time.
This not a reflection of the drift but my riding.
There is another thread called look before you leap where the rider has drift written on the side of his helmet so I am guessing that is the camera it was filmed with.
