ab-av1 VS NotEnoughAV1Encodes-Qt

Calculate vmaf before you encode the whole file. -> https://github.com/alexheretic/ab-av1 has a search mode with samples, the estimation of time and filesize is very good and does everything in one step

ab-av1 auto-encode with a VMAF quality target of 97-98 + a script for the deletion of files sounds like what you need.

ab-av1

My case is ab-av1, a cli for encoding videos. The local db stores cached vmaf analysis.

If the goal is space saving and a consistent visual quality rather than just having a library as AV1 for its own sake, I'd use ab-av1. Not sure how (or if) it'll handle the Opus audio channels cases, but bugs can be filed.

Use this tool and you will get excellent results https://github.com/alexheretic/ab-av1 calculates and converts automatically calculates the vmaf and crf properly

Check this, might help you optimize the process.

I like using NotEnoughAV1Encodes. There's also Av1an, and ab-av1.

I wish AV1 had more compatibility. Just playing around with NotEnoughAV1Encodes took a dumb 10-second clip with almost no movement from 24MB from my DSLR to 1.1MB after the AV1 encode. It's a bad example for a video, but I was just randomly trying AV1 with things and was impressed with the ratio.

If I'm not in a hurry for something to process then I set it to run on that. For instance, when I was looking at the AV1 codec I had it grinding NotEnoughAV1Encodes for days at a time.

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.

For some things, I've been going even slower using AV1 with NotEnoughAV1Encodes. Although, there's less compatibility for AV1, so keep that in mind.

NotEnoughAV1Encodes is great for AV1, I'm not savvy enough to get AV1 to grind all my CPU cores without it.

Do you do any videos? I've been playing with the AV1 codec using 'NotEnoughAV1Encodes'

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.
