How to zoom in on (or pop out) particular screen area's I would like to know how to zoom in (or pop out)on a particular boxed screen area (like menu and mouse movements) just like this guy did in this linked video. I wanted to make same thing for my Youtube tutorial series.

I think the person in the tutorial recorded, cropped and placed each individual element in his video.

You could give "ZoomIt" a try. It's a tool from Microsoft that lets you zoom while recording your screen.
