  • CRF value for efficient 4k encoding?

    I just let ab-av1 automatically find a CRF that hits a VMAF target on a few samples.
  • Easily identifying the CRF required to achieve a target VMAF

    The team who produced ab-av1 0.4.0 https://github.com/alexheretic/ab-av1 have recently extended the crf-search mechanism to support non av1 codecs. This is a cool tool that allows you to run a single command to estimate what CRF is required to target a particular VMAF. It was originally written for AV1, but has now been extended for other codecs https://alexheretic.github.io/posts/ab-av1-2/ including x264 & x265. It takes the pain way from running multiple VMAF passes.
  • AOM or SVT-AV1 on 5950X? video is 8K 60fps 60Mbit/s

    Thank you! I also found https://github.com/alexheretic/ab-av1 which can do a binary search to find the 'cheapest' CRF to achieve certain quality (VMAF)
  • Quality loss when you encode

    If you want to mess with AV1, then there's AV1an that has a feature to target a VMAF. ab-av1 has their 'crf-search.' Although, most of the time I just use NotEnoughAV1Encodes with settings I like. Although, granted AV1 has less compatibility and it takes forever.
  • JPG is awesome!

    Do you mess around with video at all? I just found out about the AV1 codec. Been using NotEnoughAV1Encodes to use all my computer cores to compress video. Then comparing the quality difference with ffmpeg-quality-metrics using VMAF. 33-second test video with my phone went down from 23MB to 1.6MB with nearly no quality difference. It takes forever to encode though. May not be compatible with all devices/browsers/etc. Then there's ab-av1 to help find the best settings.

    That's right. I do plan to improve this https://github.com/alexheretic/ab-av1/issues/2
