Now I have those R3D-Files this Laptop in Premiere CS6 cannot handle. I have huge losses of frames in the preview. The files are stored on an external HDD of Western Digital USB 3.0 1TB with 5400 RPM.
I copied some files to my Laptop, just to check if the problem is the external HDD, but have the same problems from there. What makes my GPU worse is my second problem, that we invented a new format called "DoubleScope" in which we have a permanent split-screen in resolution of 4096x772px (looks like this then: http://ostenderfilm.de/doublescope/ ) I think that playing two different 4k-RED-Files at one time is too much for my GPU (or maybe for my HDD or my PCIs??) Interesting: It doesn't matter if I scale the preview down to 1/16 or not. I am losing always the same mount of frames.
Sorry for my english, but maybe someone has a good Idea how I can handle these files? Tried to find tutorials building Proxy-Files etc. but couldnt really for RED-Files. Looks like the RED-Codec is a bit tricky?
Your GPU and hard drives are nowhere near fast enough to playback r3d files. Use redcine x to encode proxy files and then re link before your final export. You could probably drop the debayer to 1/4 in redcine x and create either prores or avid dnxhd files. These should have a low enough data rate for the hard drive you have. It's worth investing in a usb3 raid or ssd if you can afford it.
Unfortunately there isn't one perfect for solution that will always help to play r3d files back. You need a combination of very fast storage, more than 64GB ram, dual GPUs of at least 4GB each and then the only thing that would guarantee performance is a red rocket x card. You also need lots of fast spinning storage, either via fibre or thunderbolt.
For instance, to guarantee 4k playback of up to 30fps from r3d files on Mac, you would need at least 6 cores, 64GB of ram, an external red rocket card in a thunderbolt enclosure, dual d700 GPUs and a thunderbolt raid with as much storage on a thunderbolt raid 5 setup as possible.
