If you think a video is likely to be censored, you may want to download it for later viewing / sharing. A useful tool I've found for doing so is youtube-dl, a command line media downloader. It works on a vast number of websites, not just Youtube.

https://ytdl-org.github.io/youtube-dl/index.html

Once installed, here's how to download a youtube video (from a terminal):

$ youtube-dl --add-metadata --restrict-filenames

Here's what the flags mean:

--add-metadata -- include metadata information such as upload date, uploader, etc in the mp4 file

--restrict-filenames -- Restrict filename to only ASCII characters, and avoid "&" and spaces

By default, youtube-dl downloads the highest video quality, and highest audio quality. If you're on a slow connection, you can add flags that will downgrade the video/audio quality.

Here's how to install it on a Mac. From the terminal, issue this command

brew install youtube-dl
