If you want to record your computer screen with high quality, you should choose the right program. The one I used can help record any actions you made on screen with high quality, including move the cursor, launch a program, type text, click button, select menus etc. So I often use it to make tutorial video on my computer. And it help you save the video to standard video format file, so you can transfer it to your portable gadget or upload to video sharing websites.
