PS I can play 4K RED files right out of the camera, no problem, but I had some drone footage that was H.264, used Media Encoder to transcode to ProRes 422 HQ, and those files play great everywhere but Premiere.
I have similar problems…. files play great in Quicktime Player, Quicktime Pro 7 and VLC… Premiere 13.0.3 they ripple weirdly over any straight borders or straight lines.
I have Mac Pro, 64GB of RAM, 8GB VRAM and 12-core processor
