PPCC output via Media Encoder problems
I have a greenscreen sequence and have used UltraKey and a garbage matte on each clip to key background. Everything looks and plays great in PPCC timeline. But when I render out via Media encoder this is what I get. I’ve cleaned memory cache, cleared cache files, tried rendering first, reboot computer, nothing works. If I direct export with Media Encoder rather than first to the que, it outputs visually fine, but throws audio out of sync. The source material is ProRes444 in a DNX 720p sequence (this is what PP picked when I dragged footage on sequence). I have the footage track with UltraKey over a solid color background. I do have mixed audio some at 48K (sequence set to this) and some at 44K, but that has never caused me trouble before. I’m stumped and under a deadline! Yikes! Help!

Thanks!

Are you using GPU acceleration? You might try turning that off.

Just tried switching gpu off. That didn’t work. Still a problem

The garbage matte has always been buggy. I usually just do the keying in AE since it’s much cleaner.
You could try using crop instead of GM, but of course, you only get 4 point. At least that may get you through this project.

Could not solve, but workaround was to export as ProRes444, then bring that into AME, re-encode to web spec. Why this is happening???? Clearly a bug with UltraKey.

We use UltraKey on 80% of our material and we haven’t run into that problem.
Two differences that may help track down the problem;
1. we haven’t used the garbage matt with UltraKey
2. we export directly from PP, not placing it in the ME queue

I use Ultrakey on 100% of our green screen work with
the garbage matte or crop and never had any problem
with exports.mac premiere cc version here.

I experienced the same problem on a project I did around Christmas time. Ended up passing the footage onto my AE guy because I couldn’t hack the protracted output times as well with AME.
My feeling this has to do with PPr 7.2.1 because I’ve had a lot of other export problems as well. Even a sequence with just the Fast Color Corrector on the clips would take 5 times as long to output than if I used the 3 Way Color Corrector (which I hate) instead. Something’s not right with 7.2. It’s uncool when they tell you an upgrade is for “Bug Fixes” and it ends up creating a whole new slew of bugs.
I reverted back to 7.0.1 and did a test with the Ultra Key, and the headless speaker got his noggin back. Output time was considerably reduced as well. I did turn the GPU acceleration off though. -
Try turning off the “Enable native Premiere Pro sequence loading” preference in AME.

Ultra Key is the way to go IMO.
I have also run into other export issues we could not get around (Listening Adobe?)and ended up exporting a Hi-rez Master and then more compression, what a pain.

So Joe, you had the identical issue as I did? Top half of footage cut off? Very weird. I mean we should be able to use UltraKey with a garbage matte and export via AME any way we want. Fix this Adobe!
