Vegas + Decklink Studio = Thruput?
This question is for anyone using Vegas who is capturing an SDI stream using a Decklink Studio card. Does the card also throughput the video stream to the analog outputs? IE, can you use the card to both record an SDI stream as well as downconvert it to analog at the same time?
On a related note for anyone just using the stright SDI in/out Decklink card, does it throughput the SDI signal?
We’re upgrading our studio to SDI and I need to find the simplest and most cost-effective solution to downconvert to analog for a live output, while maintaining an SDI stream to our recording computer.

We have a Decklink HD Extreme that we use with Vegas. When we capture via SDI, we are able to see the output simultaneously via component on an NTSC studio monitor. So it definitely sends the SDI signal from the input back out to the component output.
The hardware setup utility (and the manual) have settings for downconverting and upconverting in real-time from a couple of HD formats and vice-versa. I haven’t tried it to see if it loops out in real-time from the analog outputs, but my assumption would be that it does since it’s using hardware to do the conversion in real-time.
If I get time I’ll test it next week. I can only test going from SD to HD though since we don’t have any HD-SDI decks.
I also believe it will throughput the SDI signal, but again, have not tried it. I imagine an email or post in the Blackmagic forum here on the Cow could also answer all your questions.
