Stop motion (also known as stop frame) is an animation technique used to make an inanimate object appear to move on its own. The object is moved bit by bit between individually photographed frames, which creates the illusion of movement when the series of frames is played as a continuous sequence. Dolls with movable joints or clay figures are often used in stop motion for their ease of re-positioning. Stop motion animation using Plasticine is called clay animation or 'clay-mation'. Not all stop motion requires figures or models; many stop motion films can involve using humans (pixelation), household appliances and other things for comedic effect. Stop motion using objects is sometimes referred to as object animation.
The reason I looked into this animation technique is because I enjoyed viewing animated films in the past and still do today and have always wanted to attempt making a series of short animation with this technique. With the Final Major Project, I will be able create a stop-motion piece or at least smaller animations as part of tests and research towards the final. Also, due to the fact that at my laptop's current condition, animating on Flash could become unreliable which I would not want to experience halfway through animating and potentially have the film only half complete at the end.
The term "stop motion", related to the animation technique, is often spelled with a hyphen, "stop-motion". Both orthographical variants, with and without the hyphen, are correct, but the hyphenated one has, in addition, a second meaning, not related 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 is often confused with the time lapse technique, where still photographs of a live surrounding are taken at regular intervals and combined into a continuous film. Time lapse is a technique whereby the frequency at which film frames are captured is much lower than that used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing.
Stop motion animation has a long history in film. It was often used to show objects moving as if by magic. The first instance of the stop motion technique can be credited to Albert E. Smith and J. Stuart Blackton for Vitagraph's The Humpty Dumpty Circus (1897), in which a toy circus of acrobats and animals comes to life. In 1902, the film Fun in a Bakery Shop used the stop trick technique in the "lightning sculpting" sequence. French trick film maestro Georges Méliès used true stop motion to produce moving title-card letters for one of his short films, but never exploited the process for any of his other films.
One of the earliest clay animation films was Modelling Extraordinary, which dazzled audiences in 1912. December 1916 brought the first of Willie Hopkins' 54 episodes of "Miracles in Mud" to the big screen. Also in December 1916, the first woman animator, Helena Smith Dayton, began experimenting with clay stop motion. She would release her first film in 1917, an adaptation of William Shakespeare's Romeo and Juliet.
In the 1970s and 1980s, Industrial Light & Magic often used stop motion model animation for films such as the original Star Wars trilogy: the chess sequence in Star Wars, the Tauntauns and AT-AT walkers in The Empire Strikes Back, and the AT-ST walkers in Return of the Jedi were all stop motion animation, some of it using the Go films. The many shots including the ghosts in Raiders of the Lost Ark and the first two feature films in the RoboCop series use Phil Tippett's go motion version of stop motion.
Reasons for using stop motion instead of the more advanced CGI include the low entry price and the appeal of its distinct look. It is now mostly used in children's programming, in commercials and some comic shows such as Robot Chicken. Another merit of stop motion is that it is superior in displaying textures. This is appreciated by a number of movie makers, such as Tim Burton, who produced the puppet-animated 2005 film Corpse Bride.
