People do various things to get the movies past youtube's copyright algorithms. They adjust color and framerate slightly, they might clip the video (i.e. remove a "margin"), they might remove telltale soundtrack, they might not mention the movie name in the description, etc., and I think if the movie is not monetized the standards are lower. I think if the algorithms don't detect it, it stays up until a copyright owner issues a takedown claim through youtube. I'm not an expert tho so I dunno.
That all makes sense!
