Supercuts have nothing to do with a wash and set, but they do involve styling and cutting. Supercut is a term of art (possibly coined by artist Ryan D. Gantz) that describes the practice of snipping categorical lists of moments, words, or elements from external works such as movies or television series, and assembling these likeminded artifacts into rapidly edited sequences. Typical examples would take words like “fuck” or “yea!” or actions like gunshots or punches that appear across a variety of disparate works and edit them together into short sequences.
The term Supercuts is frequently used as a catchall term to describe all manner of cutups, cutdowns, derivatives and other techniques. Supercuts however are specifically multi-referential, meaning they usually aggregate elements from multiple sources.
Cutdowns are a sister to Supercuts, they are however singular in scope such as a minisode or short clip that maintains the full original narrative story arc from a long form original such as a TV show. Cutups are typically unconcerned with story arc and more focused on collections such as Bea Arthur saying “whoa!” from the Golden Girls or every “fuck” from The Big Lebowski or even couch intros from The Simpsons.
Arguably there is a gray area of definition between some works. Defining a cutup as emanating exclusively from a single source leaves open the definition of the word source. For example, if the singular source is Stanley Kubrick, and even more specifically, only the one-point perspective camera shots from his movies, one might argue to classify it as a supercut (multiple references) or as a cutup (of Kubrick). I tend to draw the line in this way; In regards to TV, cutting up a single episode to produce a meaningful montage is likely difficult, so in TV-based works, I define a single source as a TV show, rather than an episode. In the case for Kubrick one-point perspective , I'd classify it as a Supercut because it draws from multiple different movies.
Supercuts can contain entire borrowed sequences, for example scenes of people being hit by buses in Hit By A Bus - The Supercut or they can be presented as machine gun–like edit sequences that transform the original source or series elements into an entirely new shared experience such as IMDB Top 250 in 2 1/2 Minutes or "Curse Me Good" (featuring 400 movies in 5 minutes).
Collections often use tricks to transform elements like Matthijs Vlot's Todotodo that musically aligns the words "to do" with the theme song from The Pink Panther, delivering a unique and transcendent offering that achieves a cleverness you'll find irresistible. Matthijs also recreated Lionel Richie's song Hello using fussily edited words and phrases to lovingly perform the lyrics in perfect sync as well as the Supercut orgasim anthology titled ooh aah that will leave you wanting a cigarette.
A wonderful resource created by Andy Baio and Michael Bell-Smith is www.supercut.org a site dedicated to documenting the cultural phenomenon in a clean, browsable index that anyone can contribute to. Here you'll find many of my favorites and some really random examples including 1980s Wrestling Stars, Just the breathing, Various Disney films — Character-on-character violence, Brad Pitt eating and drinking, Every "Who" from Who's Afraid of Virginia Woolf?, Jesus and Virgin Mary sightings, My Little Pony: Friendship Is Magic— Pinkie Pie says "Okey Dokey Lokey", Judy Jetson's teen idols, True Blood characters saying "Sookie" and perhaps the most random of all - Breaking Bad POV shots from inanimate objects.
Tricks of the trade.
There are multiple sources of transcriptions, subtitles and closed captioning data available online as downloadable, searchable text resources including the time references and the exact word or phrase placement within the timeline of the resource. Using various search and aggregation techniques, the artist is able to create a list of references across all the found resources. The hard part is then to load up the individual media in some fashion either as a DVD or file and scan to the element, rip or record the passage and file it away for later editing.
Also be sure to check out the tabTV playlist SuperMixMix that has many of the above works as well as many more not found here.
