Red Rocket question

[Tom Chase]

So, I have see a few threads that say if you are running Premier Pro CS6 and using a NVIDA Quadro 4000 on a Mac Pro tower that you may not need the Red Rocket card to bring down transcoding time? Does anyone have an experience see this to be true? I have a Mac Pro tower Dual quad-core 2.1GHz processor with 32GB's of RAM and the NVIDA Quadro 4000. Also has anyone used Da'Vanci Resolve 9 in there workflow with the Red Rocket card?

Thanks

Tom

+1 would like to know this as well

I use Resolve 9 and get great results without the RedRocket. I'm running the latest 12-core Mac Pro and will get about 14-17fps at "Half Res Good" with just one Quadro 4000. You should be able to get 12-14fps with an 8-core.

This thread feels a little confusing...

GPU has absolutely nothing to do with debayering R3D files. There are only two places they can be processed: CPU or Redrocket. So your choices are load up on CPU power or get a Redrocket (or both I guess). Redrocket is currently still faster than any CPU based debayer (including latest dual 8 core Xeons), but there is more flexibility in the CPU approach, and some argue that it looks better than Redrocket debayers though the difference is subtle.

The CPU debayer is less sharp and works well for downscaling, if you however look for a 5k/4k finishing then the red rocket render hold much better qualities in terms of sharpness at full resolution.

I've been trying to find an exact answer but could somebody point me in the direction as to what kind of time savings are we talking about if I were to go and grade an 1hour documentary shot on RED one on my 2009 top-end Macpro in Davinci Resolve without a RED rocket vs WITH a Red rocket.

Are we talking about only being able to preview at higher framerates or actually giving me a much quicker workflow?

 

[John Tissavary]

The term workflow might be a bit general for this discussion - Redrocket only does one thing, that's accelerate R3D decoding in hardware. It does nothing else whatsoever for Resolve.



It's a quicker workflow for two reasons:

1) no need for 'preview' or working resolution, then toggling to full debayer to check frames

2) faster render when the grade is finished

It's simple math. Figure you'll get a minimum of 24fps from Redrocket enabled system, higher during rendering (we typically get 35+fps) minus whatever your system currently does without Redrocket.

I get 25fps playback and render(hd timeline) with 5k footage 1/4 resolution on a Mac 2008 and gtx570 in resolve
without RR

 

[Janne Amunét]

Thanks a ton you both for answering something that's probably been answered hundreds of times before. Interesting to see what kind of playback I'll be getting in resolve without RR. Will make a decision based on that then!
CHEERS.

AFAIK the Rocket debayer is always a full res decode so comparing it to 1/2 or 1/4 res is misleading. Do you really need a full res decode for a web deliverable? Perhaps not. That said, the lower res extractions never have the same sense of depth, which I attribute to the way in which a wavelet entropy encoding scheme treats high vs low frequency regions. In a full res decode, in a typical image, the elements that have more contrast/sharpness/detail stand out more distinctly from "flatter" regions than in an lower res extraction.

Point being, to really get sweet images out the RED cams you need to do a full res decode, even if the deliverable is 720P destined for heavy compression for distribution. Because of that, I would recommend getting a Rocket (perhaps you could rent...) or scheduling a lot of render time. FWIW some of the most disappointing RED acquired imagery I have seen came from 1/2 res decodes - I suppose one could argue that's a spurious correlation since the best colorists often have things like Red Rockets and pimp workstations, not to mention nice calibrated monitors, but I digress.

Sure 1/4 or 1/2 is only for preview ...always render final in full resolution!!
