I don't know what you exactly need but I love Camtasia Studio. There are some easy and useful things. You can add captions, text, effects, work over stuff you just recovered with this program, cut, split, change audio, add whatever else and many more. If you want to make some simple vids it's good tool. There is one problem tho. It's designed to send it at first to YouTube for example. I still haven't discovered a way to save videos (.avi) on HDD. Maybe it's because I always use it to YouTube videos... It allows you to save .avi when upload fails so I guess just turn off internet connection.
