youtube to quicktime

I use https://savefrom.is .. it's very easy to use and they don't have any adware or malware and can be done without installing any software.

Just select mp4 and try save it and play using QuickTime player.

I use “yt-dlp” command line tool, if I want to archive something that may not be available for long, or if I want to edit into a short clip, or if I want to have a video offline.
