4K Grading & Monitoring
It looks like we are closing the circle for “affordable” 4K finishing:
4K adquisition – starting by RED, adding more options
4K playback – r3d with REDROCKET / good enough RAID for other formats
4K grading – Resolve with PCI expansion and a number of GPUs
4K monitoring – Decklink 4K (4xSDI)
4K projection – incoming RED LASER projector (4xSDI)
4K finishing – new finishing tools in Resolve (less need to finish in other software)
4K deliveries – DCP
4K screening – growing up fast!Now, what would be the difficulties in the Resolve configuration to have this dream working? I mean, could be possible on OSX / Windows systems?
note: at this point 2D 4K is good enough for me, but 3D is also a thing to consider.Greetings

The decklink 4K is not shipping yet …
I am not quite sure why , but is literally 1 year that they are keep delaying every 3 months …
Resolve should be Ok with 3 GTX 580 (3GB Ram) , but i goes start until the Decklink 4 is out , real test cannot be done …

Agreed, but:
– The Decklink 4K still needs to actually ship… Since it’s been pushed back quarter after quarter I wonder if there is some kind of problem?
– For 4K projection, the options are more like Barco, Christie (NEC?). There wasn’t a single working 4K prototype of the Red Laser projector as of NAB and I think it’s more likely to fall into the home cinema market than to be useful for color grading… I didn’t see any claims about being DCI compliant and Red hasn’t been forthcoming on the underlying technology and how consistent it might be.
I’m not sure about the math here, perhaps one of our GPU experts can chime in, but it seems like 4K RGB images going out and back in from 3 GPUs will approach some limitation on the PCI bandwidth on some stations (like the current Mac Pro)… I imagine that as new systems become PCI 3.0 that we’ll see an improvement here. The Blackmagic system config guide for windows has one system that is certified for 4K, and I think the main difference is that each GPU (they recommend the 580) can have a dedicated 16x slot…
But I think the Decklink 4K is the only necessary component that you can’t currently buy.

Solid real time performance at resolutions as high as 4K and above require more than one processing box can likely provide. It is this fact that is one of the primary, if not THE primary reason, for the continued existence and support of the Linux version of Resolve. At this point in time, and for the foreseeable future, I would say that for true 4K work – and by that I mean any format, not just compressed Red files – the Linux platform is the logical choice. You can hack together something on Mac and Windows systems, but it will be limited by the single box requirement and can never really match the performance of a multi-chassis-Infiniband-connected Linux system. That’s just technical fact.

I think Resolve v9 will surprise you in terms of performance on Mac & Windows.

Single-box win/mac solutions may never catch up to multi-box linux set-ups but I expect it won’t be long before single-box setups run 4K effectively and Linux will start to only distinguish itself only in 4K 3D, 48/60 FPS 4K features, and some specialty higher-than-4K DI situations. Which is probably reason enough for it to live on…
I think there will be a small explosion of new hardware configs being tested in the next couple months, with new processors, GPUs, and PCI 3.0 motherboards… I’m hoping that BM is testing these and gives us some good config updates as v9.0 comes around.

Do you think today’s PCIe can’t deliver playback for 4K RGB?

A decent SAN or NAS will deliver 1500 mb/s and will empower us with 4K playback speed.
I also trust in RED to deliver a proper projector that is much more hassle free than the Barco / Christie stuff.
And I have high hopes for Aja and other players to step up their game to 4K.
Looking forward to IBC already 🙂A slice of color…

The Red Laser projector is natively larger gamut than P3/DCI, and will be DCI compliant, according to Red. They have said they’re using lasers, and said that lasers are inherently very consistent (which is 100% correct, since they’re single-frequency light sources).
With a max screen width of 15 feet for the smallest model, it’s definitely a professional product, and should be quite suitable for small to medium sized grading suites.

We are running two Quadro 6000’s and a 4000 and getting realtime 4K from Resolve.

How are you monitoring that in 4k?
