Performance with Red media
We’ve got Resolve up and running on a 2008 Mac Pro with a RedRocket + GTX285 + GT120 + Decklink Extreme 3. That configuration can’t quite manage real-time playback in 1080p (using the on-the-fly proxies at 1600×900 works fine).
We’re thinking of buying a new tower mostly just for Resolve, and I’m wondering if we should put the Rocket in it, or go for a RAID card instead. Is real-time 1/2 res decoding + 1080p playback solid on current 8 or 12 core Mac Pros without a Rocket?

I have a Mac Pro 2009, half-res won’t play real-time. It can go maybe 20fps, but not 25, 30, 50.. Going down to quarter res works fine. And to my surprise, it doesn’t look too ugly. Then I can get any framerate in real-time.
And that’s only on a four-disk RAID0 setup…

Ola, which 2009 do you have? the 8-core 2.93GHz?
It’s interesting that it also requires RAID to work well. RED footage is pretty compressed so it’s not a lot of data per second..

If you’re still contemplating in about 10 days, I’m assembling a system that sounds a lot like that – 12-core 2.93GHz, 24 GB RAM, Decklink Extreme 3D+, GTX 285, GT 120, and with a RAID rather than RED rocket… and one of the first things I’ll test is 4K RED for 2K output. However, I’m not really contemplating putting a RED rocket in permanently, if it doesn’t play 24fps, I’ll just figure out what get me closest…

Would you like to sell that red rocket card. My plan is to build a second workstation for conforms with realtime red camera debayer. My color system will have the big raid card my conform box the rocket raid.
I will continue to work in dpx for grading.I sure could have used that card over the past two days conforming this camera red feature.

I have the basic model – it was all I could find on the market late august..
Mac Pro 2009, 8-core 2.26GHz, 6GB RAM, GT120+GTX 285, HD Extreme 3D and 4TB RAID0 through eSATA. -
Hey guys,
since Red updated the sensor and the camera firmware to 30.x it is quite impossible to play back RED files with the new color science in anything but quad res.
You NEED the rocket if you want real time performance and the capability to make good use of the high exposure, the full media and possible 4K of the Red file.
However , I tend to assemble from Red, export to DPX with handles and leave 10 percent head and tail room with either going 16bit tif or Redlog to preserve as much color information as possible.
I like using the DPX due to the fact i have to do a lot of picture in picture (boom in frame) or two pass gradings with home made glows and stuff. -
Tested RED r3d media (HD res) on a 12-core Mac Pro and got real time playback at half res good setting. With the CPU activity meter opened, at half res good, each CPU cores were about half but once set to half res premium, all the CPU cores went through the ceiling and playback was around 20fps.
Also another observation, at half res good setting, when doing a object tracking, all the CPU cores went maximum as well.
I didn’t have any RED 2K/4K media to test but I’d reckon it may be possible to playback RED 2K in real time
with half res good setting.-chrispy

Well, that debayer would take 4 times as much CPU resources.
Anyone willing to chime in and do an actual test with S-RED 16 4K in all six qiality debayer modes ?
