staxrip

🎞 Video encoding GUI for Windows.

Project mention: HandBrake 1.7.0 – The open source video transcoder | news.ycombinator.com | 2023-11-19

Its literally a feature of all the underlying encoders. And you can do it even with exotic ffmpeg/vapoursynth filter chains. So I can't imagine why.
TBH I would just recommend Staxrip if you are on Windows: https://github.com/staxrip/staxrip
There is a linux equivalent, I can't remember what its called.
Or maybe some av1an GUI for Mac/Linux. All of these things support a target file size with many more features.
Av1an

6 1,338 7.3 Rust

Cross-platform command-line AV1 / VP9 / HEVC / H264 encoding framework with per scene quality encoding

Project mention: Guide to Adopting AV1 Encoding | news.ycombinator.com | 2023-11-03

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
