Also, when recording screen, a good trick is to put your desktop resolution into 800x600 and still lower the game screen enough so that you can somewhat see your character and are able to perform the combos. This way you’ll be saving lot’s of PC power and are able to record without any lag. This is just a method that I use when recording combos with Hypercam.
The clips I cut later on with Videomach, though that’s not what you asked for. Just telling incase your curious
PS. When uploading on youtube the videos that you recorded on ‘800x600+lowered game screen’ will look just fine on youtube, incase you want to share your video in there.
