The topic has come up a couple of times on the Barn, about what do you do with the GoPro footage that you shoot. Windows Movie Maker is decent, but not very user friendly. Imovie is great, but if you don't have a Mac, your out of luck. Well, GoPro has released a new editing program, for free, that is very good and easy to use. I just downloaded it and so far it compares with Imovie for ease of use. It doesn't have the advanced bells and whistle, but for free its great!!
