Here's a short compilation of snowboard carving from Jan + Feb 2010. The riders are Peti, Lowcarver, and Alexey; they are riding boards from Oxess, Virus, and Prior. The first clip is at Zillertal Arena, and the rest are at Hintertux glacier.
The video was made with a Canon Vixia HF200 and Kenko 0.5 wide angle, helmet-top-mounted, then stabilized with Virtualdub and Deshaker. The Kenko lens has a bit of barrel distortion which I think is leading to the slight distorted effect at the edges when there is heavy vibration. Shutter speed from 1/250 to 1/500.
