I'm looking for a free GUI that can download a YouTube channel in a particular language (i.e. Japanese) with it's associated English subtitles preferably in SRT format.

I used 4K Video Downloader which worked fine for the "old" YT even though it was limited and I had to uninstall and reinstall a few times I got exactly what I wanted.

Then Google in all their stupidity decided to put all streams for a single video together so I can't get what I want from 4K without downloading the video and then splitting the stream some way and downloading the Japanese audio to go with it.

Can anyone give me a simpler alternative to what I'm trying to do? I would appreciate any constructive input. Thanks!
