Screenshots and moviesFollow

I was wondering how to take screenshots and make short movies of my charactor in action.

Use your ditgal camera as a tape recorder and fix so that it gets only the screen and nothing else and play then once you won't to record something then just press record button and there you go.

Once you done take the data and up load it to the computer and use your movie maker program and the rest is up to you.
Sorry if I sort of dumb it down just trying to be correct.
