ScreenPressor

ScreenPressor allows you to record screen activities to a very small video file with 100% quality. It is a video codec designed specifically for screen capture. It is lossless which means it always keeps 100% quality (no artifacts at all!) and it has the best compression in its field, making your video files smaller than other codecs. It can be used with any screen capture application like the free CamStudio or commercial Camtasia and HyperCam.
