How to make movies off computer screen?

Question by Joe: How to make movies off computer screen?
So i want to be able to make a movie of the screen.
eg. what going on on my screen without physically holding a video camera at the seen.

I don’t know if ive made it obvious as to what I want to do but a lot of the time you see these videos on youtube and they have “unregistered hypercam” in the corner.

So some of these videos will be recording of whats going on on the compuer and they won’t be recorded by a camera but by like the computer itself.

Anyone know what im talking about and how to do it?

Download for a free hypercam, but has a watermark on the screen
