People have begun uploading 1080p movie trailers to youtube as 4k clips just to make a few bucks on ads. Here is one example. They even go so far as to turn off comments so people can't call them out on it. Even more pathetic is that not only are people now linking to them in lists of 4k clips available online, they are giving them good ratings.
It would be great if Red could make a site for high quality 4k trailers as apple did years ago for 1080p ones. It would be really sad if this problem causes people to come to the conclusion that 4k looks just the same as 1080p and skip watching the 4k version of The Hobbit and other movies in the future.
