GoPro's HD Helmet HERO® camera shoots with such clarity you may develop a visceral need to strap on a parachute and follow Neil Amonson off a cliff.
Shot in 960p (1280x960) HD resolution. 960p is a 4:3 aspect ratio, which means you're going to see 25% more top/bottom viewing area than you do with 16:9 widescreen aspect ratios. Both are killer, but in the case of this base jumping movie, 960p shows more of the cliff as its passing underneath, and more of the scenery above and below. 16:9 would look good, too...just not as immersive.
