AJA-HA5-4K and Premiere Pro - can't get smooth UHD playback
on Sep 9, 2016 at 6:57:01 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
