steams

Hi! Been QC-offline for a while, but with new projects awaiting I´m trying to recap my options for mixing live video streams in QC 4.

I´d appreciate your views on this.

So, anyone out there mixing two HD streams ?

I was mixing PAL on a DFG-1394 with HD on an Intensity Pro with OK results up until QC 3 broke the ability to select DFGs Pal input. (Still kind of works, but only presents NTSC)

Upon installing the Intensity, capture from an older analog Deckling card was also broken.

So in QC3 I was stuck mixing HD with a Pal camera connected by composite to a Sony DSR11, then Firewire to QC. Latency and resolution of course not optimal…

Two Intensity Pros should mix out of the box in Blackmagics own software. But I have seldom seen QC accepting two signals from two equal devices. (Though I was able to fool it with two DGFs back in QC 2)

Witch brings me to the later MXO-mini…

But a Matrox representative states: “Having both the Intensity Pro and the MXO drivers installed on the same system might generate conflicts” http://forum.matrox.com/mxo/viewtopic.php?p=7068&sid=c15a590afbc116f933f...

He is talking about the MXO, not the mini, but I guess problems would be similar.

Also there is the instability issue, as demonstrated by vade: http://createdigitalmotion.com/2009/08/10/matrox-mxo2-mini-review-uncomp... even before introduing another device.

Two HD sources at decent framerate/latecy, as far as I can see, would still only be viable on desktops? The Axis HD cameras might work, but I guess the quality/functions here is as expected from a surveillance camera.

Also, I’m interested to hear if anyone has connected the new SLR HD cameras with success.

Happy winter. Boya
