Good luck convincing skiers who make $100K a year in contest winnings (and sponsor matching) to focus on video segments? Why would you? Its not in their best interest. Their sponsors are paying them to compete, not to film and wear their bodies out and risk injury. I would gladly trade all the hard work and effort in producing a solid, full video part for hopping on the contest circuit and walking away a whole lot richer, but thats just me.
I think the reason there is such a divide in movie segments and contests is that it seems like skiing can't get rid of its competitve nature as a whole. Look at pro snowboarders, once the contest season is over, the contestants go to BC to sled, or off to Alaska to get in a heli--and have a blast doing it. Skiers seem to keep their focus on training for next season, just traveling in search of the best park or pipe. There's nothing wrong with that, we arent skateboarders, or snowboarders. If you feel the need to fit into their culture, pick up what they have under their feet. Or just go ski what you want to ski and if you have the right combination of skill, attitude, and patience, you'll get noticed and hopefully compensated somewhat accordingly.
