Mein Teil official making of?

Does anyone have the official video of Mein Teil official making of, or know how to find it? When you search that up on Youtube, you'll find many low quality unofficial videos instead, but I saw a guy that reacted to the official making of Mein Teil, and it looked like the original video, it was 31 minutes, and really high quality. The video of the guy reacting to it is like 4 years old, so I'm wondering if the video doesn't exist anymore, or might be unlisted?
