Video plays back as colored static
I've had a problem with this since CC 2015.4 (I've been using 2015.3 instead) where sequences with h264 clips play back as green static or static of other assorted colors. Prores clips have fewer problems, but if there are effects or motion effects added it'll also appear as colored static.
I captured playback of a few sequences as an example
1. All h264 clips
2. Prores 422 clips, some with effects applied
3. Prores 4444 clips, then switching to original h264 clips
Premiere Pro CC 2015.4 - 2017.1 Glitch - YouTube
Has anyone seen this or know what the problem might be?
I'm on a 2010 Mac Pro with a Radeon 5770 card for the main display, and an added Quadro 4000
Thanks!
