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.

Hi there,

 

We're sorry about the poor experience. We can get this checked. Are you getting the error for any specific H.264 export, or all of them? Also, if possible please share a screenshot of the complete error message that you are getting at the time of export. We're here to help, just need more info.

 

Thanks,

Sumeet

Hi there,

Thank you for your response. I am getting the error message for all H.264 exports when I try to enable hardware encoding. If I check software encoding only, I am able to export fine. Given that I have a 2021 iMac, my hope is to be able to make use of the hardware encoding. The root question and issue I am wondering about is this: Is the integrated GPU on the M1 chip in the new apple computers able to interface with the latest version of Premiere software to allow for hardware encoding?

 

It has been difficult to find solid information on whether or not hardware encoding is compatible in Premiere with the integrated GPU configuration on the M1 chip. The sense I get from the scattered information I've come across in my digging is that it is perhaps not currently compatible. One indication that premiere and the M1 GPU are not currently compatible is that when I try to click on the "Video Rendering and Playback" drop-down menu in my project settings in Premiere, the drop-down menu is grayed-out, as in, I am unable to click on it to view any of the options for GPU acceralation/configuration with Premiere. I read somewhere that this means that Premiere is not in communication with my computer's GPU, but was unable to find an explanation or resolution for the issue.

 

So just to recap my specific issue:

1) is it even possible to enable hardware encoding between the 2021 iMac M1/GPU and the latest Premiere 2022 software ... and

2) if it is possible, what do I need to do to get premiere to recognize and make use of the M1 GPU on my Mac? 

 

I am attaching to screenshots to illustrate the issue. The first is the error message I receive whenever I try to export an H.264 with hardware encoding enabled. The second screenshot is of my project settings window which shows the video renderer and playback menu in its grayed-out, un-editable appearance, which is what I come across every time I click on my project settings.

 

Thank you for help and followup,

Cameron

Hello, is there anybody there from Adobe? Please see this thread and how the problem seems to be affecting many people with the M1 chip. Please respond.

This forum is primarily user-to-user (like me) ... with oversight by Product Support staff, who by Adobe structure, are not part of the development team. So posting that sort of comment here doesn't get it where you want and need it to go.

 

Post about this in detail over on their Premiere Pro UserVoice site, where every post is logged into their system by at least one engineer, and more importantly, all posts are collated and sent up to the all-important Royal Mugwumps of the Marketing & Experience offices, who are the ones who actually make the top-level decisions on what we users truely, really need ... via the Magic of Metrics.

 

As opposed to what we users merely think we need ...

Suddenly encountered the same problem. I had to uncheck hardware encoding to be able to export H.264 again...

It is the first time this has happened to my M1 Macbook Pro, which I have used for almost 3 months now.

Suddenly we have the same issue on a 16" 2021 M1 Max... only software export works with h264 across the entire adobe suite. Please look into this!

Anyone figure this out yet? Been having the same issue just purchased this 2021 m1 macbook pro 16gb of Ram for a huge editing project and it's performing worse than my 2014 macbook pro. Export errors due to running out of application memory, no way to enable gpu acceleration. Glitchy timeline like I've never experienced and dont even know how to explain. Terrible playback, super long render times. I'm running mac osx 12.5 and updated to premiere 22.5 and was crashing like crazy I read somewhere that premiere 22.1.2 was better so I Installed that and I can atleast see where I'm positioning graphics now but it's still not great. On 22.5 I would have to guess where I was aligning the graphic because it would not show me in real time on a paused sequence then re render to see where it went and guess again. How can you say that's optimized for m1 if you can't even enable gpu acceleration?

Hi, ScottyEdits,

I am so sorry about your performance issues. I also have an M1 MacBook Pro with average specs. I'll do additional testing today to see if I have similar issues. I'll certainly report those. In the meantime, you can upvote a bug report on User Voice. Here is one that could use some traction here: https://adobe-video.uservoice.com/forums/911233-premiere-pro/suggestions/45352495-m1-playback-delay-...

 

I have some concerns, though. What kind of footage are you working with? Is it 4K? Have you scaled it to HD? Do you have a lot of GPU-accelerated effects in the Timeline? What about other hardware? For example, are you using a second or third monitor? That can impact performance. 

 

These M1 Macs are great, but when it comes to GPU acceleration, they seem to have their limits (like regular video cards do). I advise you to install Premiere Pro Beta and test your workflow before updating to the next version. I hope Beta will perform better, and you can upgrade and solve some of these problems. I will also give Beta a shot with my 4K footage.

 

Though I can't verify this, I have also heard that the current version is less performant than the previous version. You can also reinstall that application if the Beta has not solved your issues.

 

Let me know if you have any questions or feedback I can bring back to the team.

 

Thanks,
Kevin
