I am miking and recording the cabinet separately .... straight into Logic on my MAC. Mic > API pre > Apogee Converter > MAC. Video and audio are synced afterward ... the audio straight from the mic is always a bit more difficult to deal with unless you have excellent mics hooked into the camera ...
I think you are referring to the "hybrid picking / string skipping" technique ... honestly, that is a newer thing I picked up from listening to musicians like Guthrie Govan. For that matter, I've seen some awesome videos from Andy Wood using that technique as well ... both those guys have a good handle on using that kind of technique in a rock setting. I know the Nashville players are true masters of that style .... guys like Brett Mason. You can check all three of those players out to hear it done really well!
