FCP Crashes with Blackmagic clips on MacPro
I just upgraded to MacPro and FCP is not working with the Blackmagic 8-bit clips that I normally use. When I press spacebar or try to scrub a timeline with a Blackmagic clip in it my machine completely locks up and must be powered down and restarted. I was getting a kernel panic message screen. I reinstalled everything (including OSX), now I don’t even get the screen of death, it just freezes. The interesting thing is that once I reboot the offending clip plays fine everytime.
Quad 3G MacPro, 4G RAM, OSX 10.4.8, FCP 5.1.2, Adobe AfterEffects 7.0.1, BLackmagic Decklink Extreme slot4, ATI RadeonX1900 slot1.

Just did a little more experimenting. Its also locks up with a WAV file that I exported from After Effects. Again after resarting it plays fine.

I had this issue as well.
Plausible cause… Current Blackmagic drivers (Decklink 5.8) can only support up to 3GB RAM per their Read Me doc – You have 4GB installed.
Remove 1 GB or 2 (remember to keep the RAM even and paired on each riser). Hopefully this will be addressed soon, as you (we) will have to take a performance hit to work within the 3rd-party driver’s current capabilities.
In my case, I noticed the kernel panics became more frequent as the timeline became more “complex” (ie more math) with needed renders for CC, motion effects, etc. I didn’t have this issue with just the raw footage. I finally gave up and pulled out two 1GB sticks… ouch!
Also check for the explanation of the kernel panics in your /Library/Logs and please post. Also you may want to make sure you do not have any bad RAM. Try “Rember.”
Best of luck and Happy Holidays!
