I took this torrent https://nyaa.si/view/1322540 and encoded it in av1, all sub and episode resolution is the same. The only difference is that I didn't include the 4kids dub. The command used for encoding is: av1an -i filename -c mkvmerge -e aom --chunk-method lsmash --split-method av-scenechange --sc-method standard -x 0 --min-scene-len 1024 -v "--bit-depth=10 --cpu-used=4 --end-usage=q --cq-level=25 --kf-max-dist=240 --kf-min-dist=12 --lag-in-frames=63 --frame-parallel=0 --row-mt=0 --tile-columns=0 --tile-rows=0 --arnr-strength=4 --arnr-maxframes=15 --enable-fwd-kf=1 --enable-qm=1 --enable-chroma-deltaq=0 --quant-b-adapt=1 --enable-keyframe-filtering=1" -a="-c:a libopus -b:a 96k" I used aom-lavish. A big thanks to Stay_Gold for the complete torrent and to all the various groups that made the sub for the show!
