What do I need to start using iStopMotion with a Panasonic HDC-HS700

Although a PC user for 30 years, I am new to the world of Macs. So all I need to know(!) is which Mac, which operating system and which version of iStopMotion would I need to make full screen HD “claymation” videos?

All the PC stop-motion software I have looked at seems to need additional hardware in order to give live streaming. Will the program and the Mac do the job without any add-ons?

I am after onion-skinning, Chroma Key and any other goodies that I don’t yet know about.
