Coined word: shrediting.

Shrediting: shredding someone through editing, as typically seen in a reality TV show, where a film editor, to create a story line, selects clips from hours of footage to give a very negative impression of a person. See "The Apprentice," Season 4, Episode 4 (character: Toral). See also, "The Comeback" (a sitcom in which the central character is filming a reality show without realizing when she is unwittingly providing the material that will be used in the final edit to shred her).
