This is a useful link for downloading videos from many sites:

Every one I’ve tried has worked so far. Disclaimer Note: the alphabetical directory of supported sites is very long, and includes a lot of, um, “unsavory looking” ones, but if you’ve got a video that you want to grab at places like Bitchute or Rumble, etc., I’ve found it works well.
ThankQ.
