    Media Encoder making 4K output file 'blink'... What is going on?


      Working off Premiere CC. I have a 4K sequence displaying two 1080p videos side-by-side to compare quality between HEVC and H.264. Effects includes dissolves, freeze frames, and word labels created with Premiere's title maker.


      Watching all the way through in Premiere timeline on my new Mac Pro it works fine. All video loaded, audio playing back, everything is great.


      Ctrl+M, settings include Quicktime, Apple ProRes 422 (HQ) (have also tried Uncompressed YUV 10 bit 4:2:2 as an alternative to no avail), 3840x2160, 29.97, Progressive, Square Pixels, check box on 'Render at Maximumm Depth and 'Use Maximum Render Quality'. Queue it up, hit play and the video encodes fine for a while. Then, during a random transition, the little preview monitor on the encoder starts blinking! Sometimes the top half of the screen, sometimes the entire screen. Upon review of the final output shows that the preview was telling the truth.


      Help! What is going on?!
