It may be just me, but as a film fanatic, I have an eye for telling apart kinds of film. I feel these new screenshots of Out to Lunch might've been from a quad tape, based on how different colors look and differentiate from colors on regular videotape or film. Another factor being the quality of the pictures- slightly lower than most video tape transfers. Though all these apply, I could be wrong.
Also, the new snuffy pic, along with the rest of the screenshots of that episode, is in unrestored quality, which is kind of interesting to see!
