Have you got hardware acceleration working? I'll often take half a TB of 360 footage on a trip, and stitching it on Linux via Bottles isn't viable due to me not having hardware acceleration working. It takes days on my current Linux setup, as compared to less than a day with HW acceleration on Windows.

I have been just considering getting a Mac Mini M4 for 450 bucks next time it's on sale and using that as a DaVinci/Insta360 render server.
