Fyi videos are insanely easy to download from fetlife if you view page source and copy the mp4 domain.
Example of what it looks like: https://videos-google.fetlife.com/5422522/7db3b56b-81e7-4fac-a936-2b7ff68eb223/720p.mp4?token=1706400000_ed19c937051f6246cbbdecacd86253c0c9102dbe46896846a3b6de43058f8751
i also tried to google it found error 402 payment required, and already check with inspect page, just found for script for play video that support rather than the link that you post
the problem with this system it uses token generate, and cmiiw token you can get after you pay
