    PPro 2015.3 UHD playback HDMI to AJA-HA5-4k - Major dropped frames during playback

      Hi,

      Looking for solutions to UHD output via HDMI to AJA for 4k SDI playback. Experiencing terrible playback from Premiere Pro...dropping frames like crazy.

       

      Windows PC

      2 x E5-2697v3 processor

      128GB RAM

      Hardware Raid 0 (8x2TB SSD)

      Single GeForce GTX Titan X12GB

      PPro CC 2015.3

       

      Trying to play a string out UHD seq of 10 clips, encoded as cineform QT at 29.97fps which PPro supports natively without need for render. Output HDMI to AJA5-4k to convert to UHD SDI which feeds a 4k pipeline for large projection system.  Can get fairly stable UHD playback before connect to AJA. When connected to AJA, major dropped frames during playback.

       

      We have also tried a KONA card and no difference...actually worse.

       

      Anyone done 4k output converting to QUAD-SDI successfully? Really would appreciate some advice and real world experience. .

       

      Thanks,

      Phil
