Help Exporting in Premiere Pro 2021

[Abstractnxgen]

I have a 12hr clip in 1080P 60FPS that I am cutting up into different videos. I have a 2-and-a-half-hour chunk that I am trying to export with a file size less than 2GB. I am using H.264 with the YouTube 1080P settings and have made sure premiere is using my mercury cuda in project settings. I am using VBR at 12 and have made sure hardware encoding is selected. I have let it try to export for about 4hrs for it to only get to 10%. This is insanely slow. I check task manager and see that my CPU sits around 9% and my GPU at a steady 3% so they are not really doing anything as far as I can see which is what I am think the issue is. I do not have an integrated graphics and I have installed the studio drivers for my graphics card and that does not help either. I have tried to follow multiple guides about this issue and nothing I have tried has worked. What am I doing wrong and how can I fix it?

PC Specs:

Ryzen 7 5800X

Asus TUF Gaming x570-Plus (WI-FI)

G.Skill Trident Z Neo (2 x 8 GB) DDR4-3600 CL14

Samsung 980 Pro 1TB M.2

EVGA GTX 1660TI 6GB XC Gaming

And an Elgato HD60 Pro but I do not know if that matters.

Try these 2 steps: 

1) Turn off hardware accelerated Decoding in Preferences > Media...  (Remember to do app restart)

2) Manually clear media cache - close Adobe PP/AE/ME, go to cache location and clean/delete folders: Media Cache, Media Cache Files, PTX, Peak Files

Thank you so much! Number 1 did it for me, now its 20mins for exporting instead of a lifetime. I know about clearing the media cache but this is my first project and do not think that would matter yet.

Hi Basil,

I've heard there is a fix in the 15.1 Beta. Can you check it out and verify for the community? 

Thanks,
Kevin

No. Versions 15.1 beta and 15.2 beta are the same.

Gives nothing...
