I wanted to show my friend a video clip from a movie I have on my computer, and since I'm using Windows 7 RC1, it doesn't come with video editing software. Since I'm already trying out new things (Windows 7 being my case in point), I thought I would check to see if there were any advances in the Movie Maker department. What I found was Windows Live Movie Maker Beta, which is pretty dead simple as far as video editing goes.
You can: add text, stitch entire videos together, add music, add some simple transitions, and trim the ends of a video. That's about it, in a nutshell, although I'm hopeful that they'll be adding more features later on. For now, it's good enough for simple editing/combining videos. For saving videos, you can save your project to work on later, or you can output the video at 640x480 or 320x240 (both in .wmv format).
