Canon vixia and BMD ultrastudioexpress

[Novamedia]

Hello;

I am going to order a new Blackmagic ultrastudioexpress . I have a new macbookpro 15" i7 2,3 quad 16Gb ram. I´d like to know if the new canon vixia line HF R36-38 or M 52/56 are appropiate for livestream events. Any suggestion about cameras would be nice. Procaster sees Atem TVstudio, I´d like to know if I can stream with procaster from ultrastudioexpress card

Thanks
