Made in Abyss Video source: Prime https://nyaa.si/view/1169926 Sub source: Asenshi-PAS https://nyaa.si/view/1130356 Audio was encodec using Opus 128Kb/s The command used for encoding is: av1an -i filename -enc aom -cm vs_lsmash --split_method aom_keyframes --reuse_first_pass -xs 9999999 -v \"--bit-depth=10 --cpu-used=4 --end-usage=q --cq-level=19 --frame-parallel=0 --row-mt=0 --enable-cdef=0 --kf-max-dist=256 --tile-columns=0 --tile-rows=0 --lag-in-frames=35 --arnr-strength=4 --arnr-maxframes=15 --frame-boost=1 --enable-fwd-kf=1 --enable-qm=1 --enable-chroma-deltaq=1 --quant-b-adapt=1 --auto-alt-ref=1 \" -a=\"-c:a libopus -b:a 128k\" The source was 99GiB(It was a blu-ray, a comparable reencode using x264 is about 11GB) . If you drop frames in scenes were there are lots of movements and you use mpv you can try this https://www.reddit.com/r/AV1/comments/gjq2mv/drastically_improving_av1_playback/ It should help if you can decode on average at more than 1x speed but drop below that on heavy scene, but if you are always below 1x it won’t help much. A big thanks to Asenshi and PAS for the fansub and to Prime for the video raws!
