Whats the catch behind AV1? Should I be converting every video I have to it?

it's VP9 but slightly better.
>Should I be converting every video I have to it?
no.

Why not? I want to save space

i'm too retarded to explain!!!!!!!!!!!

okay, if you care more about the savings (like i do with audio desu), go for it. i recommend you do heavy experimenting and benchmarking on your own. for starters, check these pages out.

shit's taxing to enc and dec
same strange unpredictable variable rate target as VP9 making you re-enc 2-5 times to saturate file limit
dunno how the fuck VP8 was soo accurate with that

SVT-AV1:
--crf 34-38 --enable-variance-boost 1 --tune 1 --aq-mode 2 --enable-tf 0 --tile-columns 1 --tile-rows 0

this should compress H.264 videos by around 60% while not losing much quality

also beforehand play source on mpv and check primaries, matrix coefficients and transfer characteristics, if it's encoded with bt601 colorspace add this: --color-primaries 6 --transfer-characteristics 13 --matrix-coefficients 6

i'm too lazy to translate it to ffmpeg for you but whatever isn't possible to pass to ffmpeg as an option like the variance stuff, it can be passed directly to the encoder using: -svtav1-params option1=arg:option2=arg
read SvtAv1EncApp --help if you want to go down the rabbit hole

blurry shit that's only good for anime and super low bitrate slop. For anything where you actually care about how it looks h264 remains unbeaten

it can do high quality but like x265 it requires more than just crf/bitrate and speed args

It's basically a combination of x264 speed with x265 compression efficiency. It's practically the last video codec you'll need for decades at least. You don't even need a computer to encode it anymore. It's so fast that you can compress AV1 video on your FFFucking telephone. Not just at slop youtube quality either, webm related passed quality validation and achieved 40% lower file size compared to the original H264 copy. Retards who don't know what quality validation is will just babble like idiots as usual as evident by this thread though.
