AV1 is very fast and versatile but…
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
-
AV1 tool to auto compress old video files for archive
ab-av1 auto-encode with a VMAF quality target of 97-98 + a script for the deletion of files sounds like what you need.

Automatic choose encode settings?

RFC: redb (embedded key-value store) nearing version 1.0
My case is ab-av1, a cli for encoding videos. The local db stores cached vmaf analysis.
- I'm just running videos through libsvtav1 on ffmpeg with -crf 35. Any tips to improve this command?
-
A little script to parse large libraries to AV1, if you're interested
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.

Feels like re-encoding video gets harder and harder to improve (and use!) when new ones come along.

Looking for some good AV1 testing and comparison results.
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
- automatically optimize (re)encoding quality

CRF 15 x265 advanced options
Check this, might help you optimize the process.

AOM or SVT-AV1 on 5950X? video is 8K 60fps 60Mbit/s
I also build from my own SVT-AV1 source with a few modifications which make the encoder a bit more robust as well: https://github.com/BlueSwordM/SVT-AV1
What are some alternatives?
