Actually. there are many kinds of these screen recorders on market. If you want to record video from your computer screen with high quality, you should choose the right program. The one I used to capture pc screen video works well on me. It can record everything on screen with high quality, what you see and what you hear can be captured. And it also help you save the video to standard WMV video format. If you want to the video to be another format, its built in video converter can help you transfer the video to other format as you wish.
