Where can I find the longer version of this video?

I saw this video on another website where the quality wasn't the greatest. I cleaned it up a bit, however, I noticed within the comments of that post, a user mentioned that there's allegedly a longer version of the video (20 minutes, give or take) 'somewhere'. I would be most interested in finding said video, if it exists. I did find what appeared to be a longer version, however, it was a looped video of the same scenes and not what I'm looking for. Thanks for any and all help and happy hunting!
