yt-dlp. Too many options to remember and look up every time, but all useful and missing from GUIs when you just want to dowload audio or 'good enough' quality video in batches without re-encoding.
While nmtui is perfectly fine for the CLI-uninitiated, I sometimes wonder why the nm-connection-editor window doesn't provide the same level of functionality.
There’s a firefox extension that generates the cli command for whatever video you’re on. Let’s you check boxes for the format, sponsorblock, etc and then copies it to your clipboard.
Just search the addon store for yt-dlp and it should show up
You can have most of the settings pre-loaded in its config file. I mostly let it do my preset -f, or when that fails do a -F to see what encodings are available.
I believe ytDownloader might be what you're looking for. It's a yt-dlp frontend, you can export to video/audio pretty easily. And it's in active development. I've used it to export short clips to WAV a few times, nothing too fancy, but so far it works pretty well.
With just having options as checkboxes for YouTube-dl. It has served me well all these years.
It was literally the thing I made while learning programming so the code is pretty janky when I look back at it though...
