Looking for a good free video download program

[badjer27]

I use 4K Video Downloader for downloading video clips of subjects I’m studying.  It’s excellent for many websites like YouTube, but many websites just won’t respond, and I can’t find any straightforward way to do this.
YT-Dlp has been recommended, but I would prefer a GUI based program.
Any free and easy-to-use program that will let me do that would be great.  Many programs claim they will work with “hundreds of websites”, but usually don’t. 
Any constructive and practical help appreciated.

With free ones you usually get what you pay for  =  Rubbish and unreliable. (And Possibly other "Extras" included - Malware)

This is not free, but there is a fully functional 30 day trial. https://www.internetdownloadmanager.com/  Thats more than enough time to try it and if it suits - Buy it, if not uninstall it.

Some sites, depending on how the video is streamed the downloaders simply wont catch them.

If you are studying through a provider, they can usually supply you with the right programme. Otherwise...
