Question

Unable to use Hardware encoding

I have recently purchased the MacBook Pro with 

  • Apple M2 Max with 12‑core CPU, 38‑core GPU, 16‑core Neural Engine and 96GB of ram.

i am also running the latest version of iOS and premier

 

i am disappointed that I paid a lot of money for an upgraded machine, and premiere pro cannot use hardware encoding when I want the bit rate to be CB or VBR2 pass. It will only allow software encoding which takes incredibly longer. I only want to export high quality projects and this is making me unable to do so ina  reasonable time frame.

 

software encoding a 4K video with high bit rate too my MacBook Pro nearly 16 hours to export.

when I use hardware  encoding but VBR1 pass, the same video took approximately 25 minutes. 

need this issue to be fixed.

I presume that you're after a solution. Blaming either Apple or Adobe won't bring this anywhere near soon.

 

Perhaps you can consider the following approach: export a ProRes 422 Quicktime file and then use an encoder (could be Media Encoder) to transcode that to a VBR2 pass h.264 or h.265. Please bear in mind that h.265 encoding will bog down most any system.

 

If it doesn't work as expected, make it work as intended.

I have the exact same specs, please tell me you have a solution???

If you're trying to do 2-pass long-GOP hardware encoding, RJL is absolutely correct.

 

That cannot be done using the GPU. On anything.

 

My desktop is a 24-core Ryzen 3960x, 128GB of RAM, 2080Ti. Works very well in both PrPro and Resolve daily, as it was designed to do. Doing a 2-pass encode will be totally on the CPU.

 

My last 'main' is my backup, was an Intel CPU with 'quick-sync' and a 1080 GPU. Still runs Pr & Resolve decently if not as fast as my new rig. But still, 2-pass encodes are software-only.

 

Because that is the way all long-GOP 2-pass encoding is done on any hardware I've ever heard of.

 

If you have something that does CPU encoding of 2-pass H.264/5, then hey, let the world know. You've got something new there then!

No hardware does 2 pass encoding, period. For any computer that is a 1 pass job.

 

And in technical terms, software processing of H.264 exports has frequently been considered the higher quality.

 

Hardware is generally faster, software better. But normally only by a small amount you have to hunt for.

 

I don't know how well Mac systems do long-GOP encoding. On PCs, only certain Intel CPUs can do it.

    What you're trying to do is currently impossible regardless of hardware and software. This (hardware encoding supported only in VBR 1-pass) is imposed by all of the GPU makers. No software can circumvent this restriction.

     

    Try doing the exact same thing in DaVinci Resolve or Final Cut Pro, and you will find that although those software may let you select hardware encoding, only to get slammed ungracefully into software-only encoding immediately upon the start of exporting.

      That is simply NOT true. Where did you get this info from? VBR 2 Pass is much better in quailty and MACS should be able to handle it. I have the EXACT same specs as above who posted on this page. Its extremely concerning that Adobe NOR APPLE for that matter has made this problem aware. Its extremely fustratiting because I paid so much money for this only to use Premeir Pro. Not I am stuck in a hard place. 

      Adobe, PLEASE create an update and sort this issue out. Apple Tech has said that they cant do much from your side, they have created an computer that can handle that but its Adobe who has not invested into coming with a solution.
