FCPX Slow Export with only part of CPU

Hi. I have a brand new 2021 MacBook Pro with M1 Pro and 32 GB of memory. I’m now exporting a ~10 minute 4K video in ProRes on FCPX and it’s taking a long time. I know it’s really big file so I wasn’t all that concerned, but then I looked at activity monitor and saw that my laptop I s only using between 5-10% of the CPU with over 90% listed as idle. I also still have well over 10gb of RAM free. What’s going on? How can I optimize to make it go faster?? Thanks for the help

MacBook Pro (2020 and later)

How long? The M1 Pro should handle 4K ProRes easily. Do you have lots of effects or something particularly intensive like noise reduction?

The low CPU usage may be normal, as I understand it the device has a specialized unit to encode and decode ProRes.
