Wondering if there's a quicker way than downloading each video individually with something like a chrome extension and how people have created the giant site rip torrents. Any software or methods to batch download and rip these entire sites?

If you know a bit of python write something with BeautifulSoup or selenium and find the video tag src which is most likely an m3u8 playlist or .mp4.
if its m3u8 you can use ffmpeg to save it as mp4.
Each website is different so no single tool can be used to download all the videos.
Most of the sites are wordpress that use a plugin to protect the videos by checking if you are authenticated so its easy

5 or so years later, but for the record a program called yt-dlp can do batch downloads and it has very wide compatibility. See https://github.com/yt-dlp/yt-dlp

It's command line only. Easiest way is to run a linux vm (Ubuntu etc). Sample command to do a batch download would be: 'yt-dlp -a dl.txt'

dl.txt is a text file with one link per line. Name it whatever you want.

Lots of other instructions and options in the link above, but yt-dlp works on a very high percentage of sites.

If yt-dlp doesn't work, things get harder. Often as Dent has suggested the challenge can be finding the source URL. One app I've found useful for that is a chrome extension called 'Video DownloadHelper'.
