U should try fraps if your computer is good , because fraps use quite alot of RAM and the video file is very big because is HD , do not use trail version of fraps , it's suck as every 5 min u have to press record again and if you are making any long video then u should buy fraps , after you record the video you should edit and render the video with editing software because , trust me , the video file is huge , it will take forever to upload it to youtube . U should use sony vegers to edit video with fraps .
