Hardware encoding Issue on h.264 video export: Premiere Pro 2022 on 2021 Imac w/ m1 Chip

[defaultbxq7ffxr75jv]

I recently updated premiere pro 2022 on my 2021 imac (m1 chip processor).

I have never had this issue on the 2021 version of premiere, but now when I try export a h.264 video from timeline like I've always done, I get an error message about compiling the video.

I have tried all these suggestions already:

- restarted the computer

- made a new sequence 

- made a new project 

*none of these worked. 

Also for some reason after I updated premiere, I can no longer click on the drop-down box for the video renderer settings in my project settings. The box that reads "mercury playback engine ...." is grayed-out and unable to be selected or reconfigured. From what I've gathered, this means premiere is not able to read my mac's GPU maybe?

H.264 videos will export fine when I select "software encoding" on the export settings of my project. But I'd like to be able to use the Hardware encoding. Any help figuring out how to fix the issue of hardware from an M1 chip apple machine not being able to work with premiere pro (and the 2022 version of Pr specifically) would be IMMENSELY appreciated. I am losing my mind trying to figure this out.

Thanks.

Sorry about that, Scotty. What happens if you work in a 4K sequence and do not scale it down to HD? Scaling adds on a layer of complexity. Another thing to try is to create HD transcodes and use those in an HD sequence, which would be even easier on that machine. 

I've read that the Mac you have has a GPU about as powerful as an NVIDIA 1080ti, so there may be limitations in performance when you have 4K, scaling, and effects in a large project. I am bummed that you can't get decent performance, though.

Thanks,
Kevin

Have same issue with both of my M1 Max and ultra macs! 
Never had such a problem in Davinci or Final cut!

Working with 4K footages Prores 422 HLG and cannot export H264 or HEVC with hardware encoder! So I have to export them as Prores and convert them using compressor or Davinci!😐

please fix it.

Same...M1 Max - Macbook Pro. Need to render out as ProRes then downconvert.

Someone from Adobe! Please respond! There are now 26 replies in this thread. One would hope this would be enough to flag someone's attention to respond to this issue!
