  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

DaVinci

Anybody got a bead on the release date for $995 product?

I spoke with one of the deallers last Thursday, and he assured me tha it will not be ready for sale after the last week of July, and he said that that is a conservatory dates.

So, let's hope that it will be ready for mid August. Just a guess...
 
did anyone got to the Davinci demo day in london on friday 18th?....if so how was it?
 
Grade raw RED files in realtime!

How is that achieved?
 
Hi Jake,

Will it be up and running at the time for the release of software version? How much do you think a GTX285 handle?

If a Mac Pro with GTX285 with RAID can be the basic workable system for the software version, that will be awesome, and I hope they support MC Color, too.
 
I saw it at the London event. I was certainly impressed, and at $1000 it is a bargain.

It should be noted that only the Linux system with all the bells and whistles can grade RED footage at 4k in real time. The OSX version currently needs to work with a 1k de-Bayer to get real time.

Hi Nick,
Am I right in thinking the GTX 480 is the fastest card they will be supporting? I'm sure I read that somewhere (Probably in this thread!). Was the 1k de-Bayer for this card or for the 285? What I'm getting at is whether or not with up and coming cards we are likely to see an improvement quite early on as these newer graphics cards are supported by Apple.
Cheers
Paul
 
Obviously I can't speak for BMDs future plans in terms of what they will or won't support. I got the impression the 1k limit was due to the fact that they do not support the RED Rocket, so a good proportion of the CPU power is taken up doing the de-Bayer if you go higher than 1k, so the limit is CPU not GPU dependent.

I understand that they do not currently have plans to support the Rocket, as with the two GPUs, a Decklink Extreme 3D and a RAID controller, all four slots in a Mac Pro are used up. If Apple release Mac Pros with more slots I guess that might change.

Hi Nick.
Obviously, unless Peter from BMD speaks up, all this is speculation on my part, but..
The main difference between Mac and Linux version is a number of GPUs installed. As you correctly stated, only Linux right now is capable of real time multiple streams of 4k and beyond, where Mac is limited to 1k real time debayer. As the number of GPUs is the only difference between two systems, to me that means, that all debayering and rendering is done mainly with GPU and not CPU. Taking this to it's natural progression means, that by simply plugging in a new, more powerful GPU or increasing it's number will increase the system performance. This pretty much corresponds to what I'd been informally told by BMD engineers. BTW, grading with 1k proxies in real time doesn't mean, that you can't render 2k or higher. It just wouldn't be in real time. IMHO, it would be a lot to expect a 4k real time grading with $1k software.

Unless BMD have access to something from RED that nobody else has, then de-Bayering has to be done on the CPU not the GPU, as they have to de-Bayer through the SDK like everybody else, and that is not GPU accelerated. DaVinci then uses the GPU for grading.

Absolutely. Nothing at all wrong with grading 1k proxies and then rendering at your deliverable rez. I think some people may have unrealistic expectations of what the $1k software is capable of, so I was just clarifying (my understanding of) the situation.

At NAB I personally saw at least 6 or 7 layers of primary and secondary grades, keys, defocus and tracked masks all in the real time in HD and no proxies for DPX or QT and with Red RAW at half debayer. With "Live proxies", which I believe is a unique feature of Resolve, you can increase the number of layers still. There is a good video floating somewhere of the demo of Resolve on the Mac, where BMD demonstrates those capabilities.
The support for control surfaces is left in the hands of manufactures. The protocol is released to public, so it's up to manufacturers to write the code. Wave support is the only one written entirely in-house by the BMD.

Talking with them at NAB, they were definitely interested in supporting the Rocket. But like you point out, there's really no way to make it fit right now without more slots in a Mac Pro or PCI expansion. The latter being rather impractical when trying to support multiple high-bandwidth cards -- Two graphics cards, a Rocket and a blackmagic card...

I'm definitely interested in DaVinci, but it would require me buying another Mac as the two Mac towers I have don't have a free slot for the Quadro card. I think I'll let it mature a bit or will see what Apple delivers with their next update to the systems, hopefully in the next two months.

As I said in my earlier post, it's pure speculation on my part. I'm not aware of Resolve on a Linux doing something similar to cluster CPU computing like FilmLight, in order to deliver 4k debayer and multiple 4k streams in real time. Resolve derives it's true power from it's ability to accommodate up to 16 GPUs. So, if number of GPUs is the only differentiator between Mac and Linux versions (again speculation on my part), then increasing GPU performance on the Mac will deliver increased debayering capabilities as well.
I too would like to clarify, that Resolve on a Mac is NOT a 1k grading system, as it's been originally implied. It's fully capable of rendering pretty much any resolution.

Well, there is a way to free up a slot, but from talking with BMD engineers I got the impression they weren't really interested in that idea. The idea is to NOT use the required BMD card for the SDI output. I pointed out, that majority of Mac version users will have no need for SDI output and they will be happy with just HDMI or even dual DVI output directly from GPU, just like any other color grading systems. But, I guess, that would mean, that BMD will not be able to sell you additional hardware. I would even be willing to pay a premium for HDMI version, if that meant, that I could plug in the RedRocket. Are you Peter listening?
 
"If you need more power for high resolutions such as 2K or 4K, stereoscopic 3D feature films, or real time grading of raw RED files, then just upgrade your DaVinci Resolve with Control Surface to a full Linux software license. Available from selected DaVinci resellers, adding this software license lets you smash the limitations of a single computer because it allows a cluster of computers with high performance GPU cards, so all processing is always real time. You get the power of a super computer, and the full license means you can just keep purchasing GPUs and CPUs via high speed InfiniBand for as much power as you need. Add 1, 2, 4, 8 or 16 GPUs, and it's all possible because only DaVinci Resolve scales up as your needs increase!"

But Jake... how many Mac version users wanna spend another $4750 for Red Rocket card?
 
scratch debayers through the GPU asfaik ( i am pretty sure)...that means they use their own debayering sheme or red provided them a SDK where debayering is done on GPU.

Thinking about the ten thousands of scarlets coming to the world...i guess we will see a SDK with a GPU debayering (kudos to Brians Brain)

But would be cool if someone from RED could chime in and give some insight...would be lovely...graeme, rob?

SCRATCH does have GPU debayering for other cameras. R3D material is strictly CPU + Red Rocket.

This is not a limitation of R3D or of any other camera. It is determined by what is the best and most efficient processing for a particular set of requirements.

Best,

Lucas
