Black magic SDI output

[jcranfill]

I have a Blackmagic Decklink Extreme card that I would like to use the SDI output if possible for Catalyst. Is this possible? If yes, how would I configure my Mac for output 1 or 2 to send out the SDI?

Not possible.
You have to use the main graphics card and convert to SDI externally.

Cheapest method is the Decklink DVI Extender:

but it doesn't support ALL formats of SDI

My standard recommendation is for the use of TVOne Scalers to convert to SDI and HDSDI. I use these all the time.

Simon, what are your experiences with these? Do you see a large frame delay? Do they play nice delivering a good EDID to the Mac?

[Mr_P]

Not measured the frame delay.
They have to be connected directly to the Mac, rather than thru a DVI DA and have a small app to configure the function - SDI or extender

Very cheap option though...

However - I still use and recommend the TV-One Scalers for everything else...

works very well....

but will not output 59.94hz so don't try sending it to the OB truck because they cant sync it......dur

Apparently the grafixs card needs to output 59.94 for the extender to output 59.94

I'd second that. Don't try putting them through DA's. For a cheap way of getting HD SDI out of your Catalyst then they are great. They are also faster than Image Pro HD's IMHO.
