Guide to Adopting AV1 Encoding
The hardware encoders are very fast and generally better than x264 (but not by as much as you'd think with the x264 slow preset).
In addition, there are threaded AV1 encoders you may be overlooking, like SVT-AV1. For non-realtime, my favorite is av1an, which also yields better quality than is possible from aomenc: https://github.com/master-of-zen/Av1an

Automatic choose encode settings?
Basically Av1an.
There's also Av1an as suggested by someone else. It's going to produce more efficient encodes because it uses chunk-based encoding to reach the required VMAF for every single chunk, but this is also slower because every chunk will be re-encoded until the VMAF target is reached. It's also a PITA to compile, has a long list of bugs, and isn't very actively developed. One of the long-standing issues is that frames have a tendency to go missing during splitting, which IME is going to keep happening when the input files aren't standardized. And thus the recommendation is to transcode the input to lossless first, which is just completely unsustainable.

VMAF is confusing me
Have you seen Av1an? It's supposed to encode to a target VMAF.

AV1 Encoder development series Part 1: working on rav1e in a different, better and more forward manner
Here's a couple of pages that cover the basics of aomenc: https://github.com/master-of-zen/Av1an/blob/master/docs/Encoders/aomenc.md https://gist.github.com/shssoichiro/a46ff01db70243c1719479f6518ea34d For more of a deep dive into settings, you can join the discord, lots of people share their settings and you can see what's working well for others.

Should I recompress video I shot with mobile?
Av1an can even aim for a target quality.

did I fail at preserving dvds? mpeg2 vs h264 vs av1
I like using NotEnoughAV1Encodes. There's also Av1an, and ab-av1.

Currently impossible to use av1an on Windows?
In your case, I'd get one of the [nightly builds](https://github.com/master-of-zen/Av1an/releases/tag/latest) of Av1an. They should work with ffmpeg 5.

Compression question
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.

Virtual Nas on ESXI or Something
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.
-
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.
-
transcoding to optimize occupied pace
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.

H264 -preset and -crf benchmarking results ( and why use should always use VERYFAST)
NotEnoughAV1Encodes is great for AV1, I'm not savvy enough to get AV1 to grind all my CPU cores without it.

Variable Bitrate Formats are Cool
Do you do any videos? I've been playing with the AV1 codec using 'NotEnoughAV1Encodes'

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.
