If this were the usual 700MB DVD rip, I'd say very bad. Seeing how this is only 100MB, that's quite impressive. Compressing a movie down to a bad MP3 encode bitrate is something.
Still though, there are a lot of noticeable artifacts. I don't think I'd watch this as it is on anything larger than a 5" phone.
@matrix @alyx @PurpCat @beardalaxy sorry I forgot to post it. I had to lower the resolution to 360p I made 2 versions. One with opus and one with aac_he_v2. aac_he_v2 is less efficient than opus but it supports proper vbr encoding to a target quality instead of just ABR encoding which allows it to place more bits at more complex parts and less bits at less complex parts resulting in slightly better quality because despite being less efficient it can adapt its bitrate much more efficiently.
Here's the encoding settings used:
ffmpeg -hide_banner -i ~/rtorrent/download/Shrek.2001.REPACK.BluRay.1080p.TrueHD.7.1.AVC.REMUX-FraMeSToR/Shrek.2001.REPACK.BluRay.1080p.TrueHD.7.1.AVC.REMUX-FraMeSToR.mkv -y -strict experimental -c:a libopus -b:a 40k -ac 2 -c:v libsvtav1 -crf 54 -preset 2 -svtav1-params input-depth=10:tune=0 -g 240 -vf "scale=w=-2:360" -pix_fmt yuv420p10le -movflags faststart -metadata:s:v handler_name="VideoHandler" -metadata:s:a handler_name="SoundHandler" ~/nvme/shrek-opus.mp4

@j @PurpCat @alyx @beardalaxy Looks decent for 100mb. Modern codecs are quite OP. You could probably fit a DVD quality movie onto a CD.
How slow was that transcode though? When I use even preset 4 it only goes at like 0.6x and doesn't even fully utilize the CPU
@matrix @PurpCat @alyx @beardalaxy about 21fps for 360p at preset 2 (the other one was at 720x480 and preset 3)
Here are the settings I use to make files for personal streaming:
ffmpeg -hide_banner -i ~/rtorrent/download/Shrek.2001.REPACK.BluRay.1080p.TrueHD.7.1.AVC.REMUX-FraMeSToR/Shrek.2001.REPACK.BluRay.1080p.TrueHD.7.1.AVC.REMUX-FraMeSToR.mkv -y -strict experimental -c:a libfdk_aac -profile:a aac_he -vbr 5 -c:v libsvtav1 -crf 25 -maxrate 12M -bufsize 100M -preset 6 -svtav1-params input-depth=10:tune=0 -g 240 -pix_fmt yuv420p10le -movflags faststart -metadata:s:v handler_name="VideoHandler" -metadata:s:a handler_name="SoundHandler" ~/nvme/shrek.mp4
This encodes 1080p at about 52fps. Here's the result: https://mega.nz/file/5sECgKqC#Zpc_S0gFm1PW4H-DyM4X70n2H3rplXtjQyrReZWPiTQ
