From videographicessay.org, a definition of a Videographic Epigraph:

"For this ‘videographic epigraph’ assignment, we asked participants first to select a favorite quotation from some critical text that could serve as an epigraph—not specifically related to the media object they were working on. The quotation could not be more than five sentences long. Next, the participants were to select a continuous scene or sequence from their film object and alter it in some way—through slow motion, image manipulation, or some other visual or temporal effect. The source soundtrack was to be replaced or significantly altered via effects."
