ArcSoft ShowBiz

This is the first ever video editor for Windows 8 apps. It actually works pretty well for small video editing. The free version limits you to making small resolution videos. You can pay $9.99 to get the full version though. I hope there are more transitions and other options with the full version. The editor seems nice, but you really need the full paid version to make it worth anything more than a look.
