Okay, I'm really bummed at this point. Upgraded to 10.9.4 and Premiere Pro CC 2014 yesterday, cleaned my media cache, and the problem persists. I'm editing with DSLR and MXF files.
Here is a render via AME using GPU acceleration. See the familiar green glitch at the top. Seriously?
Here is a frame playing from the timeline in premiere. Not a render, just a frame of video in the timeline. I've applied Shine, which I freshly installed today. Seriously???
Months of waiting, lots of false fixes and promises of upgrades, and this is what I get. I'm sooooo disappointed. Adobe doesn't seem to be addressing this issue anymore. Kevin Monahan's last mention was:
"It seems as if the problem has gone away for most people except in very few cases. The things these cases seem to have in common is that all of you seem to have .R3D source footage"
Well, I'm not working with RED footage (but will be soon), the problem persists, and I'm the guy who stated this thread, which is somehow labeled "answered" by Adobe. My only move is to take my mac into the store for service, which I'm praying will finally fix this ridiculous issue.
