Thanks for looking into this for me. After your suggestion, I figured out what I was doing wrong!
The file got converted to interlaced in my workflow, which I believe caused the flicker, and pixelation I was seeing on the screen. I can’t believe I wasted all this time, and it was a workflow issue.
Just out curiosity, what should should the pixel aspect ratio be set to on the project and video/time line level 1.00 square or 1.22 widescreen?
Thanks.
