Fun With a Helmet Cam

I was on the verge of buying a cheap uderwater camera when I ran across the GoPro helmet cam: a compact unit that can shoot in one of 5 video formats all the way up to 1080P HD, plus the capability to shoot 5 megapixel still images one at a time or at selectable intervals.

The GoPro is water resistant to 80 meters deep, so no problem if you want to shoot video or stills while snorkling, fishing, whitewater rafting, or skiing.

It produces videos in an MP4 format which not all programs support, but I found free software which enables conversion to more common formats, while adjustment of video quality:

At the risk of stating the obvious, the GoPro portion of the video here is the portion clearly shot from pro freeskier Kevin Wherritt's point of view. (I should also add the caveat that the video uploaded here is a quick preview edit, and is of course severely downgraded in resolution and quality for ease of online use.)
