Bug Report - PP 2020 with BMD playing Arri Alexa Pro Red
Found the issue but cant fix it. The issue is with how Premiere handles Arri Alexa Pro Res files. I dont have the issue with other media or once it has been rendered to ProRes HQ.
I have just confirmed that Adobe Premiere 2020 14.0.1 Does NOT work with Black Magic Designs products when working from Arri Alexa Pro Res Files. I tried other BMD devices and am getting the same results. Transmit to BMD devices creates flashes of green and playback that jumps forward and backwards rapidly. Repeatable.
Premiere 2019 does work without issue. Something was broken in the transition to 2020 in regards to Arri Alexa Pro Res playback via transmit to Black Magic Design Products.

Happening to me too. And another colleague I have. If you switch to Software Only it works. So it's something in the Transmit>GPU>Blackmagic pipeline. I just downloaded and tried the new BM driver 11.5 and that didn't help.
Mac OS 10.15.3, Pr 14.0.1, BM 11.5 = Bug
Mac OS 10.15.3, Pr 13.1.5, BM 11.5 = Working

Download, put in a project and activate a Black Magic Designs device and mercury transmit.
It will play fine on the GUI but not to the device via Transmit.
This file is Pro Res created by Arri Alexa Mini 3840X2160.
