Replying to My First Real Ski Edit - Japan

Hey Guys, just got myself a gopro for christmas and have made this edit of my holiday in Japan. The quality is no where near as good as it is originally. Ive been using Final Cut Express for the first time so just getting the hang of it so dont know why the qualty has gone down.

What you do guys think, im getting much more involved with this kind of thing so any imput would be great. Thanks.
