The first video is one I did this past weekend in about an hour using Sony Vegas Movie Studio 11. There was nothing fancy done on it so it was fast and easy. The other three I took time to add different effects to them. This software is easy to use and you can get as fancy as ya want if you take the time to learn it and do it. On the first video (which is actually the last one I've done) I finally got the correct rendering settings so it should look a ton better.

Looks great. May I ask how much the Sony Vegas Movie Studio costs?

I know it was under $25. I believe I paid about $16 for it. Got the Go Pro and the Sony editing software last year in Sept. I didn't want to spend a lot of money cause I had never edited before and was looking for something easy to use. What has helped is there are countless tutorial videos on YouTube that show you step by step on how to do different things with the Sony Vegas software. Anything you want to do with it, there is a youtube video to show you step by step how it's done.
