@lake You should familiarize yourself with youtube-dl tool. It's a very powerful command line program for downloading videos from youtube, bitchute, facebook and hundreds more... it's open source, free, no limitations on how many videos you can download per day, no ads, etc.
If you're archiving/saving videos from bitchute you would save it like this:
youtube-dl --embed-thumbnail --add-metadata https://www.bitchute.com/video/FBBlhta2alIW/
This will download the video, thumbnail, metadata (video name and video description) and merge them all into final one video
