    I’m upgrading to a new macpro for a reality show shot on XD cam HD. Offline is FCP and grading in davinci.

    I’m planning to get the 6 core 3.33Ghz Mac Pro with 24GB (6x4GB) RAM a quadro 4000 for GUI and a GTX 580 and an external power supply for the 580.

    My question is, will the 6 core be enough CPU power for HD grading?

    And for bonus points… If I go for the GTX 570 will the Mac pro have enough power for both the gtx570 and the GTX 570?

    [Marcus Herrick] “My question is, will the 6 core be enough CPU power for HD grading?”

    The CPU cores are primarily accessed for the User Interface and codec processing. The image values for correction are computed on the GPU/CUDA cores provided by your GPU array. In that respect, unless you are trying to deBayer RAW media, the number of cores starts to become irrelevant.

    In your case, multiple GPUs will help only in the instance where you start building complex node trees with other processes over-layered, such as noise reduction, blurring, and alpha channel compositing. I have seen YouTube tutorials that feature power-supply splitting to run multiple GPUs, but whether something that is technically possible is advisable depends on how long you want your equipment to last. Also, if you intend to house all your GPUs in the chassis, eventually you will run into a) cooling issues, and b) the reality that the #3 and #4 PCIe slots are not x16-lane.

    Further to Josephs comments, Resolve now does the debayer in GPU for all bayer formats that we support with the exception of RED r3d files which are in CPU.

    The decompression of ProRes and other similar formats, and their compression at render, is performed in CPU so if you plan on using ProRes or r3d files, 6 Cores will work but will limit your real time performance.

    Hello Marcus,

    this question is not related to the camera and davinci – is your face-light plug-in for FCP (7)
    still available?

    Just saw a nice tutorial on color grading, and the writer mention your plug-in

    They’re still up on my website which is embarrassingly un updated. just click the plug ins link.
