Premiere Pro 12 render bug w/transparency

[CloudDisaster]

I wish I was still on 11.0.2, but hey, I guess Adobe knows best.

Anywhoooo, here's one of the juicy bugs I'm faced with racing for delivery deadlines:

1. Put something with an alpha channel on the timeline.  Could be a .PNG, could be a .scc promoted to open captions--doesn't matter.

2. Try to send the encode to AME.  It sits and never processes it.  Eventually hangs.

3. Try to render it directly within Premiere - it renders out every section that had a .PNG/ open-caption completely darkened, as if the video below was dropped to 60% opacity.

4. Render it within the timeline (green) and it looks fine.  Then choose "use previews" while rendering within Premiere (AME still chokes) and your render will appear the way you intended.

5. Profit?

Hope this workaround helps someone...

I can't duplicate the issue on Windows 10 Pro (1703).  In all tests, it just worked.

Try updating or rolling back your video driver directly from the card manufacturer's site.

Our other suite doesn't have this issue with PP12 (it's how we're getting any work done), but I'm on a newer version of Windows too.  Will try parity with that suite for Nvidia drivers and see what happens.

This happens on simple CPU rendering as well though, so I'm doubtful drivers will make a difference.

Hey CloudDisaster,

Did you manage to fix the problem by updating the drivers?

Let us know.
