Are you pulling media through the 10GigE card? What ram do your 680s have? 2Gb or 4Gb? What resolution is your timeline set to?
If 10gE is pulling media, I would put it in the computer and move the decklink card to the cubix. One other thing you can do to have more consistent renders is to slow down a the processing by setting a slower max frame rate in the render config.
Like it said, it sounds like you’re hitting the gpu ram issue, but would seem odd as given you’re making DNxHD files, you should be working at HD resolution.

Did you enable “Use optimized display mode durring playback” as is recommended for single card configs?

My facts, are based on personal experience and convos with engineers at Apple. I’m glad the combo is working for you. I also use the gt120 for gui one of our boxes, but we’ve stopped using said box for FCP. It just wouldn’t play through a sequence.
I wonder, do you do tape mastering from FCP? Do you have dropped frame warning on playback enabled?
I’ve seen it first hand where an fcp install on a box with gt120 gui wouldn’t playback without dropping frames, switched out gpu, 0 dropped frames.
I’m well aware FCP doesn’t use GPU computational acceleration. But it does use openGL and the graphics buffer to draw the frame on your screen, which is why fcp requires Quartz Extreme. So there is a reason for it. I’m sure a software fix could be implemented, but I wouldn’t hold my breath for one, considering the card’s age.
BTW, it’s not just me:

And of course there are plenty of people who can’t figure out why their system is dropping frames, all of whom have the gt120, here is one such case. But these pop up all the time in the FCP forum.

Hmmm seems like you’re banging into the GPU Ram issue, but you’re not dealing with particularly high resolution stuff.
I wonder if perhaps the OS GPU address limitation is causing this. To explain:
- Mac OS X is limited to being able to address 4 GPUs. The GUI card eats one of these, so effectively you max out at 3 processing cards.
- The 690s are each effectively 2 addressable cards on the same device. So if you have 2 690s you actually have 4 GPUS!
- This means you’ve got 1 more GPU than what you can address through the OS.
Perhaps this is what is causing your issue.
My recommendation: Pull out one of the 690s and see if that doesn’t clear up the issue.
BTW, do you have any other cards in the Cubix box?

Yeah, it’s become the bottleneck in many installs. It’s ancient, and slow. And there is now a bug with fcp7 and gt120 which causes constant dropped frames in OS 10.8+.

[Joseph Owens] “Porting Revival to Mac, or even Windows (more probably) and linking it with Resolve? Bring it. I’m in.”
Pair it with a cost effective scanner. Yes, please.

“Is Blackmagic motivation to make a great color correction tool for the love of it, or is to to sell more hardware? If the answer is the second, I seriously doubt we’ll see any improvements in DaVinci’s keyer.”
If their motivation was purely making a color correction tool for the love of it, they’d probably be out of business pretty quick.
I hope their motivation is giving us great tools so we’ll want to buy more licenses and more of their hardware, so they’ll make more money.

I have used BL for several weeks at a time over a couple of years. So all together I’ve got a good chunk of hours on full baselight, and a large chunk more hours on baselight editions, where i was an alpha and beta tester. I too would like to see support for EXR mattes as you’ve pointed out.
I don’t disagree with you constantly Jake. It’s not personal. Honestly half the time I respond to you, I don’t even realize it’s you, I’m just responding to a statement. So it’s not personal.
And I’m not in favor of status quo by any means. I’m constantly trying to find new better ways to work, part of that is the software, but a bigger part is technique, approach and workflow.
Maybe it’s just a difference of style, but I prefer to find ways to make things work, and ask quietly for changes where I can’t make things work, or feel they would work better in a more direct way.
I do think it’s a bit contradictory to ask about changes, changes, changes and then complain that there are too many updates! 😉
I think we just have a different outlook on things, but I don’t think Resolve is a mediocre product. I think it’s a great one. Perfect? No, not by any means. But I great one I gladly use to get things done. If that makes me a “spade”, then so be it. I just don’t think Resolve has committed an indefensible crime! So where I feel something merits defense, I’ll gladly do it.

[jake blackstone] “Actually Juan, I noticed, that you not open to any type of criticism of Resolve. Why is that?”
I don’t know where you get this idea, which you keep bringing up. I have plenty of feedback where things can improve with regards to Resolve. Some of my feedback has even become features.
But I’m not sure why I’m defending myself to you? Do I have to be a crank about something in order for my statements to have merit?
Where I have thoughts or insights I feel are helpful, I contribute them, either directly or publicly. I’m sorry if I’m not publicly lashing one particular product to your satisfaction.
As to the question of a keyer. I have actually tested first hand the keyers in Resolve, Baselight and Luster on the same troublesome footage. While a volumetric keyer is a cool GUI innovation, in actual practice, where I tried to show real examples of situations where Resolve’s key failed and another products keyer succeeded , I actually found it very difficult to come up with a clear illustration. Bottomline finding fro me from my own testing was that shots that were hard to key in Resolve were hard to key anywhere else, and shots that were easy to key elsewhere were easy to key in Resolve.
Not saying the keyer couldn’t be improved. Volumetric samples are a nifty and helpful bit of visual feedback. I also found some of the matte tool features in BL to be really useful. I like the idea of being able to apply curves on a matte. Or sand a matte. But I’ve also found ways to accomplish similar results within the resolve toolset.

Jake, I think we can all be better. People who think they can’t learn from others are in denial and bound to fail eventually.
Dan, I’ll happily take you up on your generous offer, whether it was directed at me or not.
