You won't be able to. Yt-dlp needs to be kept really up to date because YouTube constantly blocks it. I made my own terminal program for it and I might pay someone to make the web end for it then people can use that.
But you will need to use the command line for sure. If you're on Linux it's just:
yt-dlp -t sleep "https://www.videosite.com/watch?v=VIDEO"
It will then download to the current folder you're in. I should know the output command as I've been producing and maintaining a working Sonarr type thing that uses it for years, but I just use string constants so I don't know lmao. Is it -o ?
There's also something like --merge-output-format so you can choose the file to output as MP4, MKV, whatever you want.
