Hello just making a poll, which one do you prefer? personally I prefer x265 but since the rarbg falldown i’ve seen that almost all 1080p rips are in x264, what do you think about that, and do you recommend any place to find more x265 content beside those in the megathread?

    It really is awesome. Lots of leaps forward for AV1 recently. It encodes faster than x265 in some situations with so much space saved. It’s still in the early stages, really, and the compression isn’t perfect, but for video streaming purposes, I’ll take it over x265 any day.

      on ffmpeg?
      I tested it like 6months to a year ago I think, and it had similar storage requirement at similar visual fidelity but transcoding took what seemed 5x to 10x the time

      /e: for future reference, I’m testing a transfer to transcoding to AV1 instead of hevc

      ffmpeg -i /path/to/infile -c:v libsvtav1 -preset 9 -svtav1-params tune=0:enable-overlays=1:scd=1:scm=0:fast-decode=1 -crf 50 -g 240 -pix_fmt yuv420p10le /path/to/outfile

      These are a mix of what I read here:
      https://gist.github.com/BlueSwordM/86dfcb6ab38a93a524472a0cbe4c4100
      and here:
      https://trac.ffmpeg.org/wiki/Encode/AV1

      general gist:
      preset is encoding speed, higher is faster, this setting gets me a bit faster than what i had my hevc encode set up
      tune=0 tunes for being good looking
      fast-decode lessens cpu use on decode
      crf 50 seems fine for my use
      -g 240 changes keyframe insertion to every 240 frames
      -pix_fmt yuv420p10le gives 10bit color depth which helps with dark scenes and doesn’T cost much space
