top end mac pro is only core:
I got various scenario of tv show: some of the hardest for hardware is 12 full hd layer, with 2 incoming HD SDI stream, plus about 12 layer for various res video. All video I convert to icod before starting a realtime tv show, and when offline show I convert it due recording, because sometime i receive it due recording of a tv show. PDF files from latest tv show with configuration I will send to you via forum email, with dropbox link inside.
