Stop Frame (A.K.A. Stop Motion Animation) is an animated film making technique in which objects are physically moved in extremely slight ways between individually photographed segments so that they will appear to be moving individually when played back at a fast sequence. Well known examples of this include Wallace and Gromit and Early Man, both products of the Aardman studio. The technology regarding stop motion has increased greatly over the three decades Wallace and Gromit has been around, with the differences between the show’s 1989 episodes and the much more polished episodes being greatly noticeable (more realistic looking animation, choppy editing etc.) Although various types of Stop Motion Animation look simple, the work that goes on behind them is complex. For example, Tim Burton’s 1993 film The Nightmare Before Christmas took three years to create at 24 fps. The completed film has around 110,000 frames, and more than 400 different heads were created were created for the character of Jack alone. Nick Park, creator of the Wallace and Gromit franchise, said he made the decision to not include a mouth on the face of the character Gromit when he could not reach past the character’s eyebrows to adjust the face. Park instead felt that a small eyebrow movement could have just as much effect on the character. Stop Motion Animation also caters to a more adult audience as well, the most notable example of this being Robot Chicken (2001-).
