Whats going On With The Red Screen Censored Scene on Cinematic Titanic?

I'm watching this on Hulu and at around 40 minutes in a red screen comes over the film while the crew keep riffing on the film. It last about 30 seconds. I'm guessing there was nudity but it doesn't seem like a scene for that, everyone is outside talking. Any idea why they censored that part video wise?
