DVR crashes with 8k files

[Marc Wielage]

My research shows the dual P6000s aren't completely necessary, I will be able to confirm later this week after my E5-2699 v4's and Titan XP's get here.

Mmmm-hmmmm. You let us know about that.

My problem is, even with run-of-the-mill 2K projects, once you throw 18-19 nodes and blur functions and NR on it, multiple versions, complex timelines, let alone OFX, it's gonna stall out very, very quickly. Add to that real-time debayer of 6K files... it's challenging. As for real-time 8K... I don't see that happening, particularly if you're trying to monitor at higher than HD resolution.

Anything absolutely can be done if you want to throw enough hardware and money at it. (Note for onlookers that the E5-2699 processor can cost as much as $8000 by itself, depending on how many cores it has.)

Hahaha :beer:. Yes possibly when you have that many nodes, noise reduction, blur, etc. Will certainly find out this week. But really tho, you can get 4 titan XPs 48gigs for the price of one P6000, which from what I hear, other than vram, isn't really spect out much more than the Titan XP, and built around the same GPU. Depends also on how Resolve utilizes multi GPU vram tho I suppose.

Each 2699 has 22 cores.

the limit will be the lowest vram on any single compute card, cores add together, vram is the lowest single card's....

I'd say the NVidia GTX 1080 TI looks pretty good, particularly if it's faster than the Titan X (as the reports indicate).

I would bet a 22-core machine would do very well. But again, playing back this material in the real world is hard. Even playing back original 4K Raw files under duress is very challenging. Very few of my sessions these days use less than 12 nodes a shot, and clients can and do ask for OFX effects and all kinds of complex transitions. It would not be a problem if the 8K was transcoded to (say) 4K ProRes 444 in RedLogFilm. A lot of machines can run that with no problem in HD. Getting a 4K display out of that would be challenging. Having access to hundreds of terabytes of fast storage would also be challenging. All possible, just not cheap.

I don't think average people around here at an indie level, particularly without a lot of Linux expertise, could put together a system capable of running 8K material effortlessly. At least... not yet.

Your right, building a solid system for 8K including all the hard drive capacity required for multiple projects is not for the faint of heart, not that its hard to build, which I recommend everyone to give it a try (especially if your sick of apples noPro nonsense), but the big component costs can get up there quickly. It needs to be a massive system no doubt. Where necessary, my fallback, and I imagine everyone else's, is Resolves fantastic node caching. When projects start to get thick that will have to be kicked in on the heavy nodes. Regardless of that even, and with my monitoring solution, I imagine ill be at half res Premium soon as things get heavy, if not from the beginning.

1080 TI, yes!, I hear its going to be 12 GB, hopefully pushing the cheaper than Quattro next years Titan into 24, maybe 16 GB. At the rate Nvidia is releasing new GPUs it will get cheaper to compete with Red's bleeding edge resolution push a lot sooner than later. It really is too bad tho the RRX stops at 6k decode, with GPU's not taking on that side of things very effectively, that would be a cheaper solution than mass multicore dual CPUs, coupled with cheaper better GPU's around the corner people would be at 8K playback with a relatively lighter draw on the pocket book.


Edit: As I type this, Nvidia announced the 1080 TI. 11GB VRAM and about the same specs as Titan XP for $700.

Letting you know... So 2 P6000's don't perform much better than my XP titans... As I expected. 8K full to begin never uses over 6.5gb vram on each. Getting 8K full res 24fps in Resolve no prob, half res I can load 8 NR and Blur nodes and still get 24fps. Ordered another Titan to get more nodes at 8K full. But ya, save your money and buy Titan over Quadro.
