Dropped Frames on Mountain Lion
I installed Mountain Lion on my Mac Pro 8 core. Everything seems to work fine, but FCP 7.0.3. I get dropped frames after a few seconds of playback. This system works fine with Lion. Any ideas?
My setup is:
Mac Pro 5,1 8 core
15gb RAM
System on 120gb SSD
Data on 12tb internal RAID
Nvidia GTX 570 (non EFI)
DeckLink HD Extreme 3D+Thanks in advance,

Hi,
I have the same problem (very similar setup). Big problem when recording to tape!
Let me know if you figure it out.
I also have flicker when playing mov files in quicktime on all mountain lion macs

Hi Borko, I havent figured it out yet. I think it has to be a problem with Mountain Lion’s nvidia driver. But I didn’t swap the GTX for my ATI for testing yet.
Here FCP stops playing around the first 5 seconds of play. If it goes beyond that limit, it can play the entire program.
Let me know if you find something.

I have the same problem, dropped frames in FCP7 with Mountain Lion on a Mac Pro 8 core and a Macbook air, even with DV footage. Booting in Lion with same project plays perfectly, no dropped frames. Let’s hope update fixes…

I am having this same issue. Just changed my system from a Kona 3 to the BMD Decklink 3D+ card and upgraded to Mountain Lion and now it’s drop frame city.
I was running FCP 7 for about 4 days in Mountain Lion prior to swapping cards with out drop frames so it looks like it’s the Decklink.

What PCI slot are people’s Decklink cards installed in? Mine is in slot4, only other option for me is slot3. Haven’t tested swapping yet.

Has anyone found a solution to this? I recently tried isolating my NVidia cards from the system and disabled the NVidia drivers with no luck. The only thing that solved it was to disable the driver for the Blackmagic DeckLink, but then I have no video output. This wasn’t an issue under Mountain Lion with my Kona 3 card, but that card is incompatible with Resolve.

Mine is in slot 3. Are you positive that the issue is with the DeckLink? I thought it was nVidia related.

Hi, I think the issue is with black magic audio. I changed FCP audio outputs to use internal line out and it looks like the problem is solved!
-
Yes, the audio out on the Blackmagic card does seem to contribute to the problem. However, problem just changes, I get video out with out dropped frames but now my audio is out of sync!

It’s definitely DeckLink. I isolated everything NVidia out of my system and the problem persisted.
