capture ProRes 422(HQ) Kona 3 crashes system
well, I spent 2 days on this issue…
Mac Pro 2008 OSX Leopard, nVidia 1900, 8 core, 8GB ram…capture to either local SCSI or fiber SAN…from HDCam or HDV…crashes system …If I change the capture settings to say 8bit uncompressed…it captures fine.
This has happened not only on this system but also on a pre 2008 MacPro Tiger system (everything else is identical).
The only problem this creates is having to use up that much more space on my drives…
We edit just fine with Prores footage captured elsewhere, and brought in to the FCP…but can’t capture on these systems.
any known issues with Prores and Kona 3 cards that anyone knows of?
I had the Kona card in slot 2 (which the AJA website said was okay to use), then I caled AJA to confirm slot placement, and the tech said it should be in slot 3, I showed him the webpage I was looking at that told me slot 2 was okay, and he said it was wrong, and they would change it…but it still happened in slot 3 in the 20008 MacPro.

It sounds like it could be the ProRes quicktime components and maybe not the AJA card drivers. Have you tried reinstalling Final Cut Pro which should also reinstall the ProRes quicktime components? If not, that might be worth a shot. I use a Kona 3 with ProRes all the time.
Hope it helps.

Have you run the PCIe slot expansion utility? If you are on Tiger, I think you are on a Pre2008 MacPro. No?

we have 3 Mac Pros, this one is the only 2008 model, and it is running Leopard. I tracked down the cause…mismatched ram….not talking maimatched pairs…they were matched, but ALL 8GB of ram had to match, I replaced the ram with all Crucial ram, and it hasn’t crashed since when working in 1080 Prores 422.
now our other system I tested that crashed as well had mismatched ram too, so I replaced all of that with Crucial, but haven’t had a chance to test that yet…
our 3rd system has matched pairs as well, but mismatched total ram, but that seems to have other issues we are working on right now…will not boot from a full shut down unless it sits overnight….that one is going back soon…when it does get back, in with the crucial ram as well.
we have 1 quad that has all matched ram, so that shouldn’t be an issue, although I will test that as well soon.
