During AME encoding I used Activity Monitor to check out what was running.
CPU usage 18%
GPU usage 13%
RAM used 30 GB
Disk: 15 MB/sec written
It takes 18 minutes to encode a 2-hour timeline but it is hardly using the CPU and GPU and it has tons of unused RAM if it wants more. Why isn’t it using all the computing power available? No other apps are running on the computer. I also tried saving the PP project, closing PP, and then opening the project in AME so PP wasn’t even open. Same result. I have measured the SSD speed with Black Magic and it is 2.8 GB/sec read and write. I don’t see any bottleneck. It is not using any resource anywhere near it’s limit. Why is it so slow? Thanks.
