  AJA-HA5-4K and Premiere Pro – can’t get smooth UHD playback

  Posted by Phil Coulloudon on September 9, 2016 at 6:57 pm

  Hi,
  Looking for solutions to AJA HDMI to SDI UHD 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 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
