  1. #1 iMac Pro + Premiere pro = laggy playback 
    My Premiere pro on iMac pro doesn't want to play smoothly RED footage anymore, even if I put files on desktop SSD.
    Even if I choose 1/8 of the quality it doesn't play any more.
    It is mega choppy playback.

    I don't know what happened, before it was playing smooth 5K on full resolution in Premiere.

    Solved. If Video rendering is set to OpenCL it works smooth

    What was it set to before?

    Metal(2) = Apple

    OpenCL = AMD

    OpenGL = nVidia

    CUDA = nVidia driver for MAC

    Software = CPU rendering

    That's the general rule of thumb.

    I think it was OpenCL before. I noticed that all premiere settings had a reset.
