Been trying to get AME 2020 to encode in 4K HEVC (H265), but I get a very quick fail every time, with error code 7 (Out of Memory) in the logs.
Reinstalled AME 2019: it works like a charm.
So: rollback to 2019 for me, and will wait for some updates to AME 2020 first.
@Adobe Support: If you read this, I'd like to report this as a bug.
For what it's worth I am having the exact same problem but I have been unable to find any other reports of this issue nor any solutions.
Yeah its same problem here Adobe 2019 encoder works but 2020 giving me this ugly thing

January 2021: still not fixed. @Adobe Support: Are you reading this? How can this pretty essential bug stay unsolved for a year?
Just a quick note here, I was getting this exact error transcoding a very short ProRes 4444 video to HEVC, for me it's fixed by using VBR instead of CBR.
