no stupid random comment, this took over 24 hours to encode.
Sorry that these files don't work on Plex, go bitch on their [Feature request thread](https://forums.plex.tv/t/add-support-for-av1-coding-standard/556253), or use Jellyfin with it's flaws with Anime metadata.
Original source is this [RaresCelTare](https://nyaa.si/view/1233050) release.
Oh yea, the encode settings I used were `-map 0 -c:v libsvtav1 -preset 5 -crf 32 -g 240 -pix_fmt yuv420p10le -svtav1-params tune=0:film-grain=8 -c:a opus -b:a 64k -strict -2`

@usagiaddict great question, i got no clue. I pulled these settings from the svtav1 docs and was doing a batch encode and then was gonna mess with some settings later on different shows. I'll do a size check with a small show like "Himegoto" since that only took like 4-5 hours to encode (hoping that ffmpeg upstreams intels patches so i can just use my a380 cause i don't wanna mess with compiling it again)
update: crf25 brought EP 10 of himegoto up from 32.9 to 46mb, but did encode a lot faster,
Thank you for answering. It's a quite sizeable increase (for this particular show) but if difference in bitrate is noticeable maybe it's worth a shot for BDs.
Anyway have a nice day!
Also there is -svtav1-params fast-decode=1 option (but only for presets 8 to 5) but I didn't see anyone complaining in comments they have CPU problems.
Don't give them bad ideas. Fast-decode could have made sense a year ago when software decoding wasn't in the state it's in today, but now the efficiency loss isn't worth it at all.
