Hey community, i need your help with this because i don't know what to do.
Last week i start a new job and they use to edit a lot of 4k videos (up to 2 or 3 minutes) with color correction and a bunch of mogrt. My problen is that the render take toooo long for export and i have a really god pc set up.

For a 4k video of 2 minutes it takes like 40 or 50 minutes for export and i think it's crazy.

Something to add, they gave me the settings for the sequences and to export these videos, i leave them in the screenshot section.

PC

-Ryzen 9 5900X

-RX 6700XT

-16GB RAM

The third screenshot is your giveaway:

No GPU in Windows supports 2-pass VBR hardware encoding at all. Selecting 2-pass VBR will force software-only encoding no matter which hardware or software you're using in any Windows PC. Only 1-pass VBR is supported.

And this is due to the restrictions set forth by the GPU makers themselves. Neither Microsoft nor Adobe has anything to do with this restriction.

So from what I understand I would have to use Software encoding for 2-pass VBR exports?

Yes.

Even if you were to use DaVinci Resolve (which theoretically permitted you to select hardware encoding with VBR 2-pass), the encoder would have automatically become slammed into the software-only encoding mode with absolutely no warning whatsoever.

Furthermore, Adobe will warn you with an error message if you try to select hardware encoding with VBR 2-pass: "Your system's hardware does not support hardware acceleration for the current settings.". At least that's better (more forthright) than DaVinci Resolve's sneaky software-only default depreciation method.

And the choice of an AMD GPU is not as good as other GPUs for H.264 or HEVC exports since AMD currently supports only the 4:2:0 color space for both decoding and encoding. Both Intel and Nvidia support 4:2:2 and/or 4:4:4 for hardware encoding.

Hey,

Looks like you haven't enabled hardware encoding (second screen shot)? You won't be making use of your PC specs without it. I would try switching from software to hardware encoding and see if that speeds up your export times.
