i have a apple macbook air and i want a better editing sowftware than imovie for making skateboarding videos?
if anyone knows about any different good software tell me where to get it and how much they are or if you know any ways i can them for real.

There's the obvious choice with going for final cut pro but you could go for the more cheaper versions of sony vegas platinum's. final cut pro is expensive and the lower down versions of vegas are much cheaper and provide a good source of features.
