Snapz Pro with Movie Capture

I am looking at Snapz Pro for capturing video screen shots...I never needed that feature before but in writing the online tutorials I found it a little frustrating not to just be able to put in a little video showing how I clicked and opened things! Waiting to hear from the company to make sure it is in fact true that I don't have a license to cover that feature already. See Ambrosia Software for details. I believe it is a Mac-only program but I'm sure there are comparable things out there for Windows.
