ab-av1 VS encoder-benchmark

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.

The sunshine project also got me curious in video encoding. I wanted to learn more about how to benchmark encoder performance and I discovered the encoder-benchmark. I noticed a small issue on linux that prevented the calculation of VMAF scores. Fortunately it was a simple fix. The filetime method didnt work on Linux, so I replaced the method with a cross platform one. I wasn't familiar with rust, so the concept of ownership confused me at first. I also noticed ffmpeg would hang forever when it times out. I added retry logic and timeout detection to ensure the permutor-cli runs to completion. Since there was no official linux support, I decided to contribute to the Arch User Reposititory (AUR). I have published a git and non-git version. The git version pulls the latest from main at the time of building. The not-git version pulls the current git tag.

I have a tool I've developed to help make this research process a lot more automated: https://github.com/Proryanator/encoder-benchmark just added support for Intel AV1, with Nvidia on the way soon.

https://github.com/Proryanator/encoder-benchmark/releases/tag/v0.5.2-alpha this version has logic to catch whether your local networking stuff for collecting stats hangs and should fail now.
