Schretzmann received a bachelor's degree from Syracuse University in 1982.[2] For about 12 years, Schretzmann worked on several animated features at Pixar Animation Studios. Schretzmann has received the ACE Eddie Award for Best Edited Animated Feature for Toy Story 3 (2010) and for Pinocchio (2022).[3] In an interview, Schretzmann described the substantial differences between editing Pixar's animated feature films and editing a live-action feature. Among others, the animated films at Pixar each involved about 4 years of Schretzmann's work. He said, "‘What took you so long? It’s kind of a backwards process. You edit first then they shoot the film later. It’s a long haul and for about the first two years we’re in the story process.”[4]
