Honestly, I think that the best video contest I've witnessed was the gopro line of the winter...I also thought that the North Face slopestyle video comp was sick. The best online competitions cover aspects of the sport that can't be encapsulated in a single competition run though...here's my proposal for a new, 3 part NS video contest:
Round 1: Best street feature
Round 2: Best air
Round 3: Best line
I think this would be really sick because there are so many well rounded skiers out here, and not a single venue for them to show their combined effort. A loose format (not constraining Street to rails only, or Air to park jumps, or Line to a big mountain run) would open up so much creativity and interpretation. What do you think?
