These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: One episode has a very strange ending, unrelated to any game. The episode cuts to a color test, and a Japanese-accented voice says, "Cinematech is over." Then another voice asks, "Where is the copyright?" It appears in the lower left of the screen, and the other voice says, "Oh. There it is." Then the color bars slide up the screen, and the voice says, "Nosebleed."
First Installment Wins: Cinematech lasted for much longer than its Spinoff, Nocturnal Emissions, even though they were cancelled around the same time in 2007.
Fridge Brilliance: Often, they would show games that were at least tangentially related to the one from the previous clip.
Specifically, there was an episode that inserted clips from Phoenix Wright: Ace Attorney: Justice for All. The last one in the episode showed Phoenix on the verge of exposing a suspect's lies. In the clip, Phoenix demands to hear what the suspect did during a 15-minute gap. This was exactly 15 minutes after they showed an earlier clip from the same game in the episode.
Genius Bonus: A pretty nasty example. Nocturnal Emissions is a term for when a guy jizzes his pants in his sleep.
Growing the Beard: The show eventually shaved off the excess of the transitional clips between games.
Seasonal Rot: Arguably. When the 2007 season of Nocturnal Emissions began, there were fewer and fewer new clips and games being shown, almost resulting in a surreal WholeSeriesFlashback if you also watched Cinematech. Consequentially, it was the series' last season.
