Video downloads are not impossible with the right tool
Jason here. Though5t you might be interested in a heads up tech tip.
Over the years, I have had to back up my own videos, and have ..ahem ..had to back up videos that I knew would be scrubbed due to censorship and other thought manipulation, etc..
Most often, you cannot simply DL a video without becoming technically adept at finding source, etc. I found it was a lot easier to use a tool to do it. Having gone through a few over the years, the one I discovered to be the most reliable is the 4K Video Downloader. It’s cheap or free depending on use, and seems to keep up with the differing ways that video is presented or streamed.
I have been using it for about 3 years now without a hitch.
