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.
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
I’ve tried it on a threadripper and it’s still way too slow. Hardware encoding is required for anything other than short clips. Use x265 for software encoding.
cpu av1 is slow af, especially if you’re targeting ‘archival quality’. if you’re just after something ‘watchable’ (~ ‘dvd quality’), a lowly haswell i7 can do it at a ‘reasonable’ speed.
i would suggest trying a recent-gen (lovelace or newer) nvidia card with av1 support in hardware. a 4060 is running well here for what i’m currently doing. i also have a low-end alchemist (a380), but nvenc works better for me than qsv.
I only do CPU encodes at the slowest encoder preset possible (above placebo) as this is for my movies/series collection that I’ve been building for ~20 years.
I do actually watch the movies/series both by myself and with others, so this is not just OCD data hoarding. :)
