The tutorials are full window recordings in 1080p, so they look just like an active Vegas instance running but with a mouse pointer moving around and dialog boxes opening.
At a glance coming back into the room it looked like a ghost was using Vegas.
I use that graphic a lot when some forum member (in this case, you) posts something for no other reason than to see their name show up in print. You are inebriated by the exuberance of your own verbosity.
