Media Encoder Slow down and overload cpu - Mac Pro

Question

I have to convert lots of XAVC footage from a Sony FX9 to h264 for my client and everytime I queue in media encoder it start fast but after 30 clips or so the CPU are overloading and media encoder become slow up to the point it make my Mac pro crash. The GPU doesn't seems to be use at all even if the preset says it should use hardware material. At that point the only way to make the CPU slow down is to close or restart AME

Here are tthe specs from our Mac Pro 7,1

3,3 GHz Intel Xeon W 12 cores (not the fastest I know)

364 go Ram

AMD Radeon Pro vega II 32 go

footage is on a NVME raid 0 and cache is on a separate sata ssd drive

On another thread about slow premiere @Kevin-Monahan said that he suspect a bug with these Xeon CPUs and that specific format. Any developpement about that?

I am at the point that I will need to use another encoding software if I want to queue a big batch of clips without having to wait until the computer crash to restart the queue.

Any suggestions to fix that?

Thanks

Hi. Didn't have any answer about that but the problem is still there in AME 23.2

I have hundreds of clips to convert and it's a bit annoying to have to plan for a few days of work instead of queuing the file and converting them overnight because I know the render will crash at some point.

I am joining a copie of the log of the last queue in AME. You'll see that there is it take significantly more time towards the end of the queue to encode each clips. It took about 50 min to convert 45 files.

I just did a test converting the same files with similar settings in Handbrake and it took less than 30min

I would really prefer using the software we pay hundreds of dollars a month instead of a free software. Is there a fix for that or my computer is just doom with these file and adobe systems?

thanks

Dan
