See how AviScreen captures YouTube video
AviScreen is an application for capturing screen activity (ScreenCast) in the form of AVI video or images. Beside the usual options defining the capture area, AviScreen has a unique feature called “follow the cursor”. Using this mode you can produce a video or image of relatively small dimensions while covering all mouse activity over the whole screen area.
