Multiple DV Cams on Wirecast Using a Macbook Pro? WHAT!

Hey guys, some of you know me as The Tech Buzz, and I will be posting from time to time some of my awesome findings in wirecast. My editor and chief, partner in crime, Eric Norrell, suggested I share with you guys my recent findings in wirecast. So I was getting ready for my bands show this up and coming weekend and wanted to use my presonus firestudio firewire audio interface (say that three times fast) on my 15″ macbook pro 2.66ghz core 2 duo 1st gen unibody with wirecast. Wirecast being the medium where I will record the video from the show and the audio via multi track inside pro tools or maybe garage band to save on my cpu. So I purchased this express card adapter for my macbook pro thinking I could plug the fire studio into that and my camera into the built in firewire 800 port. Now being an avid wirecast user, and tester, how could I not try and push wirecast to its limits on my machine and share my findings. To my surprise not only on one bus did I get a cam to work but TWO!!!! Then I plugged in a third to the built in and we had THREE!! I sat in disbelief as I snapped a shot showing 2 cams hooked up (we know the built in one works). For $16 you too can accomplish this. I hope this helps and please submit comments, questions or feedback. Thanks and keep it buzzin’

    Late 2008 MBP 15″? I think that was the last 15″ with Express port.
    I have early 2008 variant.
    Have you tried streaming or recording yet?
    What was CPU% in Wirecast Output Statistics?

    The new 2011 15″ MBP revives hope since it has Thunderbolt and Firewire. Sonnet has Thunderbolt to Express Port device which could use the Express to Firewire adaptor.

  2. I have not tested streaming yet. Again as I did this on accident. When I get some more time, I will record a video of my findings and post it here. I’m thinking just off the cuff I’m going to be pegged at 65% to 75% CPU.
