3 Decklink Duo
Hi,
Can i put 3 BlackMagic DeckLink Duo cards in a mac pro and deal with 6 HD signals without any problem?
Should I take an 8-core or 12-Core mac?
Am i dreaming ? lolThanks

you are dreaming.
You would buy the NEW Blackmagic QUAD card. You need software to run the Duo or Quad. Specifically, Softron Movie Recorder.
To accomplish this, you will need a 12 Core (not your old cheap Quad Core) MAC Pro with 16 Gig RAM. You put in the Blackmagic QUAD interface card ($995) and run FOUR seats of Softron Movie Recorder ($1100 per channel – total price $4400). This will allow you to run 4 HD-SDI ProRes422HQ streams into your system at one time. So, what if you put in TWO QUAD cards – the MAC is not fast enough to do more than 4 streams of HD at the same time. If you put in two of these cards, you can do 8 streams of STANDARD DEF, but not HD. And of course, you need a drive array that can handle recording this much data at one time. A $200 Firewire drive won’t cut it.
So your costs are –
MAC Pro 12 Core with 16 Gig RAM
Blackmagic Quad interface card
4 licenses of Softron Movie Recorder
A big drive array.Want to do 6 streams – buy another duplicate system.

I paste you one of the answers someone’s just given me in the Wirecast forum (I want to use these streams in Wirecast)

I have 2 decklink duos in a MacPro and Wirecast sees 4 cameras. I’m guessing if you add a third card, you could add 2 more cameras.
I’m using a 12-core for this seup and it’s running at 400% so by that logic you’d need at least 8 cores to be safe.
[/QUOTE]Whos right ? ^^

$1100 per channel – ouch. That sounds a bit steep considering the entire Final Cut Pro suite costs $999 and so does the Quad hardware. I am too looking for a solution to utilize the Quad to capture at least 3 HD SDI streams simultaneously. Are there any alternatives to the Softron product?

Bob and Softron are playing it safe. You can get away with less than 12 depending on settings.
