I’ve tried encoding AV1 (1080 H264 BD sources) and it was ridiculously slow (we are talking days at the slowest preset, all on CPU of course).
It did not seem viable for DIY needs. That being said, I don’t have a Threadripper, I am assuming a 9975WX would bring it down to 4-8 hours depending on the movie length.
I would imagine AV2 is going to be exponentially slower in DIY environments. Not that streaming companies would care. They can easily buy a cluster of x64 top end Threadrippers or those dense 192 core EPYC CPUs and hire several people whose whole job is managing and optimizing this process.
Wow, I don’t even get that level of speed with x264 1080p transcodes, although I guess it makes sense preset 9 on AV1 (I’ve only done “very slow” encodes with x264/x265).
80% compression is very low though. 40% - 60% is my target for x264/x265 for moderately complex content (x265 can achieve better “close to transparent” compression for newer content, made after 2005 or so).

I encode at roughly half the material’s playtime with a 1080p source. Using a Ryzen 3600 with Handbrake/SVT-AV1 @ RF 25, Preset 9.
Edit: I achieve about 80% compression like this
