Adobe Media Encoder takes forever to transcode 4K H265 60fps X-T3 footage to ProRes 422 HQ or even creating 1280 x 720 ProRes 422 proxies. Up to 20 times more than ffmpeg: what ffmpeg transcoded in 1hr or so, AME shows 21 hours estimated.
At this moment it's unusable for me and it gravely affects my ongoing projects.
All GPU drivers are up to date, removed and fresh installed. Same with AME.
Performance monitoring while transcoding shows something like this:
I think there was/is an issue with H265 clips from some newer cameras. Have you tested to see if you get the same slower transcode times if the source is H264? Not that that helps resolve the issue, but it may be helpful to Adobe Staff.
