I posted the link of post #6557652 into the URL box of the Upload function but it just returns me with the message "File is not an image or video" but I do see some videos uploaded here that are from youtube so can you show me what I should've done?
Downoad yt-dlp and in the command line type yt-dlp {youtube url} or yt-dlp.exe {youtube url} on Windows. There are GUI front-ends you could try but I haven't used any.
