Stop motion  Stop motion is an animated filmmaking technique in which objects are physically manipulated in small increments between individually photographed frames so that they will appear to exhibit independent motion or change when the series of frames is played back. Any kind of object can thus be animated, but puppets with movable joints (puppet animation) or plasticine figures (clay animation or claymation) are most commonly used. Puppets, models or clay figures built around an armature are used in model animation. Stop motion with live actors is often referred to as pixilation. Stop motion of flat materials such as paper, fabrics or photographs is usually called cutout animation. The term "stop motion," relating to the animation technique, is often spelled with a hyphen as "stop-motion." Both orthographical variants, with and without the hyphen, are correct, but the hyphenated one has a second meaning that is unrelated to animation or cinema: "a device for automatically stopping a machine or engine when something has gone wrong" ("The New Shorter Oxford English Dictionary", 1993 edition). Stop motion should not be confused with the time-lapse technique in which still photographs of a live scene are taken at regular intervals and then combined to make a continuous film in which time appears to be moving faster. Before the advent of chronophotography in 1878, a scarce amount of picture sequences were photographed with subjects in separate poses. These can now be regarded as a form of stop motion or pixilation, but very few results were meant to be animated. In 1849, Joseph Plateau published a note about improvements for his Fantascope (a.k.a. phénakisticope). A new translucent variation had improved picture quality and could be viewed with both eyes, by several people at the same time. Plateau stated that the illusion could be further advanced even further with an idea communicated to him by Charles Wheatstone: a combination of the fantascope and Wheatstone's stereoscope. Plateau thought the construction of a sequential set of stereoscopic image pairs would be the more difficult part of the plan than adapting two copies of his improved fantascope to fit be fitted with a stereoscope. Wheatstone had suggested using photographs on paper of a solid object, for instance a statuette. Plateau concluded that for this purpose 16 plaster models could be made with 16 regular modifications. He believed such a project would take much time and careful effort, but would be well worth it because of the expected marvelous results.
