I was recommended this Screenflow software which is a video capture tool by Don McAllister of Screencasts online and I gave it a try out myself and I have to say I am impressed. I own 2 screen capture programs already but this one goes a little further in that you can edit the video that you capture with it. It is not just simple cuts and pastes either, you can do motion type edits that zoom into the movie clip and rotate clips and callouts which if you want to draw someones attention to a particular part of the screen then you can do that easily.

Here is a description from the makers of ScreenFlow -  Flip4mac
