Digital Powerhouse Error. Again.
Hi, everybody.
I’m grading 2-hour feature film shot on RED One. Project is not very complicated, about 1.5k cuts.
My system is 2008 2×2.8 MacPro, with 8Gb of RAM, Quadro 4000, Mac OS X 10.6.8 and Resolve 8.1.1.Usually I’m working with de-bayering set to half-good, but sometimes i need to check keys/noise level etc. And here comes fun: when i switch de-bayering to full or half-premium, after playing one or two shots i’m getting this frustrating message “Error occured while trying to decode frame from clip … using the Digital Powerhouse at ‘localhost:10007′”. It keeps popping on and on, and last time it popped out while project was saving, and hang the whole system (the button in error message box was unavailable and saving progress indicator stalls at 36%, so after 30 minutes i had to kill Resolve process through console, and lost couple of grades from last save).
And I’m wondering now, will it let me render the whole thing with full de-bayer???Last post on this topic (from 3 month ago) says, that this problem was fixed in Resolve 8.1. Apparently no, because it still persist in 8.1.1.
So, is there any way to avoid this errors? I’m aware of “Render speed” trick, but rendering at 1-2 fps is not an option. And anyway, it doesn’t help at grade time.

If you’re trying to deBayer 4K or 4.5K at full resolution, your Quadro4000 is nowhere near the horsepower required. I have a similar setup, and even 1920×1080 DNxHD with any Noise Reduction leaves the system gasping for air. I don’t believe this affects render quality, but “Play” preview is not likely an option with a single GPU (especially the Q4000, which is possibly the slowest option you can buy) and no RedRocket.

I sounds like you have the complete timeline in the one project. If so this is likely to cause out of memory or digital powerhouse errors, particularly on Mac. Try splitting the project in halves, or quarters.

Honestly, i didn’t get it. My system fits well in Resolve’s system requirements. Yes, it is not the top configuration, but anyway, it fits. And the only thing, that’s said in Configuration guide about R3D performance, is that i can’t achieve real time without RedRocket or Lunix multi-GPU version. Ok, i can live with it, not a problem. But it seems, that it is not the whole truth, and in reality working with full-res 4K R3D is simply impossible. Not in real time, not in any other way. And if i need to re-frame some shots by doing center-crop from 4K to HD, what is my options? I had to scale up half-res image (LOL) or do it via RedCineX prior to grade? I’m even not telling about playback, but just skipping through couple of shots on timeline makes the system completely unusable until relaunch. Why is Scratch had no such problems with 4K R3D? Maybe it is time to fix something in this Digital Powerhouse thing? Or i don’t know, at least give it option to use CPU when GPU is owerflown…
Generally i’m pretty happy with Resolve, it is a great piece of software. I have no problems with any other kind of footage, including Alexa, D-21, DSLR or 2K DPXs from scan, no matter, how many shots, sessions or nodes per shot are in the project. But the stupid things like this – it is frustrating((

I’ll try it, thanks. It is not very convenient, but i’m afraid, that i’m out of options here.
Do i had to split it in different projects, or just separate timelines in one project?Andrew Shtern

Hi, projects, the problem you have is all the clips are in the Media Pool taking Ram thats being used fully. There is a long term plan for this issue but for your project best to save the whole project as part 2 and then remove the clips from the first half of the show form the media pool and check. Once you find what works for your hardware config it will be easier for the next project to plan ahead.

Perhaps the issue here is that your Mac Pro just don’t have enough juice to let you work at premium res debayer setting ? I have a 8core 2.93Ghz Mac Pro and it will only do half res good in real time. Once I set to half res premium it will struggle, and give up if set to full res premium. RED decoding is super-CPU intensive. I have a REDRocket card so that allows me to work in premium res debayer setting.

Ok, thanks, will try it.
I’m afraid, that at the end i’ll find myself splitting 103 minutes timeline to 5 min pieces)))Andrew Shtern

I like the sound of “long term plan” 🙂

Maybe, yes, but i’m not talking about grading full-res in real time. Just the ability to check couple of shots as the still frame, thats all. But even this simple thing is impossible(
And, honestly, i still can’t believe, that 8 cores of 2.8 GHz each isn’t enough for this kind of job. I don’t think, that de-bayering of 4K is much more complicated, then processing of DSLR RAW images)))Andrew Shtern
