Timboli: As many have said, youtube-dl.exe is the one that gives you greatest control, and can be used for many front-ends out there or programs that support it like mpv.exe.
If I just want to watch a youTube clip, I
find I get much better performance and control using mpv.exe with youtube-dl.exe. I've even created an assistant program for them, that grabs the URL from your clipboard or you can paste into an input etc, and it's a ready reference for all the mpv.exe shortcut keys. That's generally how I watch all the videos at GOG.
P.S. If anyone wants a copy of my
MPV Assistant program, just sing out and I will upload to GitHub.
