[AG-TECH] Multiple Blackmagic Cards?

[Jimmy Miklavcic]

Here at Utah I have run three Black Magic Pro Intensity HDMI cards in one capture machine. I think for simple talking heads, this set up works fine. But since we use it for creative & artistic performances with a lot of motion, we found that the capture system was running at 95% of cpu capacity using the HDMI vic and H.264 codec. For this purpose we're looking into 4 single 1u rack systems with one card in each (I have four Intensity Pro cards). But to answer the original question, we have two systems (display/audio, capture).

We are also running two cards in a server and (thanks to assistance from Chris
Willing) have had no problem with them.

Out of interest Mike, do you mean stereo HD capture as in 3D ?.

regards,

Richard
