System - 2013 Mac Pro 6 core, 64GB RAM, D700, project files on Gtech studio XL raid via thunderbolt 2, audio routed via Focusrite Scarlett 18i20 USB3.0 device. Most recent version of Audition.
Playing back a multitrack audio project with a mastered video file for client preview - if we connect an additional display to the machine via HDMI and put the video reference file on this, we lose lip sync. Playing from the system monitors connected via a thunderbolt 2 port is fine. Same issue in Premiere. If we use Ultrastudio 4K in Premiere, that also has the same issue.
Using FCPX and Logic Pro X, we can do this no problem with the HDMI port or Ultrastudio. Logic Pro X also has the convenient delay for video files...
Any thoughts or is Adobe just not going to be useable for the next few projects we have?
