Why JPEG XL Ignoring Bit Depth Is Genius (and Why AVIF Can't Pull It Off)

@arichtman avif is pretty great, isn’t it?
@urlyman @arichtman @jaffathecake No, #AVIF is not progressively decoded, losslessly re-encodable with #JPEG, nor supporting splices like #JPEG_XL - see #svg2jxl: https://www.reddit.com/r/jpegxl/comments/u8kse2/svg_to_jpeg_xl/

So I have hundreds of videos of ~1 minute recorded from my phone ~10 years ago, and they generally don’t have that great compression, nor they are stored in a modern and advanced video format.
For archiving purposes, I want to take advantage of my workstation’s mighty GPU to process them so that the quality is approximately the same, but the file size would be strongly reduced.
Nevertheless, compressing videos is terribly hard, and way more complex than compressing pictures, so I wouldn’t really know how to do this, what format to use, what codec, what bitrate, what parameters to keep an eye on, etc.
I don’t care if the compression takes a lot of time, I just want smaller but good looking videos.
Any tips? (Links to guides and tutorials are ok too)
Also, unfortunately I am forced to use Windows for this (don’t ask me why 🫠), but I know nothing about Windows because I hate it. Practical software suggestions are very much welcome, too!
