Traditional animation

**Traditional animation** is much harder than today's style of animation. It often uses a stop-motion camera to "liven", or animate, the photos made by the producer. When movie-makers use stop-motion, they need to draw one picture for every scene. However, there are tools to help save time with movie-making. Other types of animation, such as limited or digital animation, can also be used now. FPS is the number of times a movie is shot in one second.

### Filming

The photographer first shoots out or edits many photos. These photos are combined to make the storyline. And as with all movies, not all scenes make it into the final movie.

### Editing

Many people help out in the editing of a movie. But in old times, people had to draw the scenes on their own. Then the stop-motion camera took a photo of a scene once a second.

## Involvement

Most movies or cartoons in the 1950's required very hard work of the editors. To make things cheaper, though, people made limited animation that used two to three copies of the same image (so the stop-motion process would be two to three times faster.)

## Current

Right now movie-makers use digital animation to "liven the movie even more". Movies from the 2000 to 2010 years are usually 1–2 hours long.

### FPS

FPS, or _frames per second_, is the number of scenes being shot in one second. The higher this is, the more "smooth" the film looks. Most movies have an FPS of 24 to 60.

### Cels

Cels, or celluloids, are tools used to "preserve" scenes. An editor uses a cell to draw a scene then make changes to it on the next drawing. It is useful when a cartoon or movie involves moving figures or objects.

### Sketcher

Sometimes a sketch pad is used to draft the scenes the editors think would be good in the movie. A sketchpad at first may contain a comic book that looks like an animation when the editors flip it back and forth.

### Live video shower

Often editors preview the animation with a video shower. On the stream of scenes, movie-makers test their animation and fix bugs or problems.

#### Impact

The spread and development of multiplane animation helped animators tackle problems with motion tracking and scene depth, and reduced production times and costs for animated works. In a 1957 recording, Walt Disney explained why motion tracking was an issue for animators, as well as what multiplane animation could do to solve it. Using a two-dimensional still of an animated farmhouse at night, Disney demonstrated that zooming in on the scene, using traditional animation techniques of the time, increased the size of the moon. In real-life experience, the moon would not increase in size as a viewer approached a farmhouse. Multiplane animation solved this problem by separating the moon, farmhouse, and farmland into separate planes, with the moon being farthest away from the camera. To create the zoom effect, the first two planes were moved closer to the camera during filming, while the plane with the moon remained at its original distance. This provided a depth and fullness to the scene that was closer in resemblance to real life, which was a prominent goal for many animation studios at the time.

### Xerography

Applied to animation by Ub Iwerks at the Walt Disney studio during the late 1950s, the electrostatic copying technique called xerography allowed the drawings to be copied directly onto the cels, eliminating much of the "inking" portion of the ink-and-paint process. This saved time and money, and it also made it possible to put in more details and to control the size of the xeroxed objects and characters. At first, it resulted in a more sketchy look, but the technique was improved upon over time.

Disney animator and engineer Bill Justice had patented a forerunner of the Xerox process in 1944, where drawings made with a special pencil would be transferred to a cel by pressure, and then fixing it. It is not known if the process was ever used in animation.

The xerographic method was first tested by Disney in a few scenes of _Sleeping Beauty_ and was first fully used in the short film _Goliath II_, while the first feature entirely using this process was _One Hundred and One Dalmatians_ (1961). The graphic style of this film was strongly influenced by the process. Some hand inking was still used together with xerography in this and subsequent films when distinct colored lines were needed. Later, colored toners became available, and several distinct line colors could be used, even simultaneously. For instance, in _The Rescuers_ the characters' outlines are gray. White and blue toners were used for special effects, such as snow and water.

### The APT process

Invented by Dave Spencer for the 1985 Disney film _The Black Cauldron_, the APT (Animation Photo Transfer) process was a technique for transferring the animators' art onto cels. Basically, the process was a modification of a repro-photographic process; the artists' work was photographed on high-contrast "litho" film, and the image on the resulting negative was then transferred to a cel covered with a layer of light-sensitive dye. The cel was exposed through the negative. Chemicals were then used to remove the unexposed portion. Small and delicate details were still inked by hand if needed. Spencer received an Academy Award for Technical Achievement for developing this process.

### Rotoscoping

Rotoscoping is a method of traditional animation invented by Max Fleischer in 1915, in which animation is "traced" over actual film footage of actors and scenery. Traditionally, the live-action will be printed out frame by frame and registered. Another piece of paper is then placed over the live-action printouts and the action is traced frame by frame using a lightbox. The end result still looks hand-drawn but the motion will be remarkably lifelike. The films _Waking Life_ and _American Pop_ are full-length rotoscoped films. Rotoscoped animation also appears in the music videos for A-ha's song "Take On Me" and Kanye West's "Heartless". In most cases, rotoscoping is mainly used to aid the animation of realistically rendered human beings, as in _Snow White and the Seven Dwarfs,_ _Peter Pan,_ and _Sleeping Beauty_.

A method related to conventional rotoscoping was later invented for the animation of solid inanimate objects, such as cars, boats, or doors. A small live-action model of the required object was built and painted white, while the edges of the model were painted with thin black lines. The object was then filmed as required for the animated scene by moving the model, the camera, or a combination of both, in real-time or using stop-motion animation. The film frames were then printed on paper, showing a model made up of the painted black lines. After the artists had added details to the object not present in the live-action photography of the model, it was xeroxed onto cels. A notable example is Cruella de Vil's car in Disney's _One Hundred and One Dalmatians_. The process of transferring 3D objects to cels was greatly improved in the 1980s when computer graphics advanced enough to allow the creation of 3D computer-generated objects that could be manipulated in any way the animators wanted, and then printed as outlines on paper before being copied onto cels using Xerography or the APT process. This technique was used in Disney films such as _Oliver and Company_ (1988) and _The Little Mermaid_ (1989). This process has more or less been superseded by the use of cel-shading.

Related to rotoscoping are the methods of vectorizing live-action footage, in order to achieve a very graphical look, like in Richard Linklater's film _A Scanner Darkly_.

### Live-action hybrids

Similar to the computer animation and traditional animation hybrids described above, occasionally a production will combine both live-action and animated footage. The live-action parts of these productions are usually filmed first, the actors pretending that they are interacting with the animated characters, props, or scenery; animation will then be added into the footage later to make it appear as if it has always been there. Like rotoscoping, this method is rarely used, but when it is, it can be done to terrific effect, immersing the audience in a fantasy world where humans and cartoons co-exist. Early examples include the silent _Out of the Inkwell_ (begun in 1919) cartoons by Max Fleischer and Walt Disney's _Alice Comedies_ (begun in 1923). Live-action and animation were later combined in features such as _Song of the South_ (1946), _The Incredible Mr. Limpet_, _Mary Poppins_ (both in 1964), _Who Framed Roger Rabbit_ (1988), _Cool World_ (1992), _Space Jam_ (1996), _Looney Tunes: Back in Action_ (2003), _The SpongeBob SquarePants Movie_ (2004), and _Enchanted_ (2007), among many others. The technique has also seen significant use in television commercials, especially for breakfast cereals marketed to children to interest them and boost sales.

### Special effects animation

Besides traditionally animated characters, objects, and backgrounds, many other techniques are used to create special elements such as smoke, lightning and "magic", and to give the animation, in general, a distinct visual appearance. Today special effects are mostly done with computers, but earlier they had to be done by hand. To produce these effects, the animators used different techniques, such as drybrush, airbrush, charcoal, grease pencil, backlit animation, diffusing screens, filters, or gels. For instance, the _Nutcracker Suite_ segment in _Fantasia_ has a fairy sequence where stippled cels are used, creating a soft pastel look.

## Modern techniques

The methods mentioned above describe the techniques of an animation process that originally depended on cels in its final stages, but painted cels are rare today as the computer moves into the animation studio, and the outline drawings are usually scanned into the computer and filled with digital paint instead of being transferred to cels and then colored by hand. The drawings are composited in a computer program on many transparent "layers" much the same way as they are with cels, and made into a sequence of images which may then be transferred onto film or converted to a digital video format.

It is now also possible for animators to draw directly into a computer using a graphics tablet such as a Cintiq or a similar device, where the outline drawings are done in a similar manner as they would be on paper. The Goofy short _How To Hook Up Your Home Theater_ (2007) represented Disney's first project based on the paperless technology available today. Some of the advantages are the possibility and potential of controlling the size of the drawings while working on them, drawing directly on a multiplane background and eliminating the need for photographing line tests and scanning.

Though traditional animation is now commonly done with computers, it is distinct from 3D computer animation, such as _Toy Story_, _Shrek_, _Jimmy Neutron: Boy Genius_, and _Ice Age._ Traditional animation and 3D computer animation can be used together, as in Don Bluth's _Titan A.E._ and Disney's _Hercules_, _Tarzan_, _Atlantis: The Lost Empire_, and _Treasure Planet._ Some recent anime and western animated series, such as _Ghost in the Shell_, _Neon Genesis Evangelion_, and _Cowboy Bebop_, have applied both animation techniques. DreamWorks executive Jeffrey Katzenberg coined the term "tradigital animation" to describe animated films produced by his studio which incorporated elements of traditional and computer animation equally, such as _The Road to El Dorado_, _Spirit: Stallion of the Cimarron_, and _Sinbad: Legend of the Seven Seas_.

Many video games such as _Viewtiful Joe_, _The Legend of Zelda: The Wind Waker_, _Ico_, _Ōkami_, _Mirror's Edge_, and others use "cel-shading" animation filters or lighting systems to make their full 3D animation appear as though it were drawn in a traditional cel-style. This technique was also used in the animated movie _Appleseed,_ and cel-shaded 3D animation is typically integrated with cel animation in Disney films and in many television shows, such as Fox's _Futurama_, _Family Guy_, and _American Dad!_ and both Nickelodeon animated series _Invader Zim_ and _The Fairly OddParents_. In one scene of the 2007 Pixar movie _Ratatouille_, an illustration of Gusteau (in his cookbook), speaks to Remy (who, in that scene, was lost in the sewers of Paris) as a figment of Remy's imagination; this scene is also considered an example of cel-shading in an animated feature. More recently, animated shorts such as _Paperman_, _Feast_, and _The Dam Keeper_ have used a more distinctive style of cel-shaded 3D animation, capturing a look and feel similar to a 'moving painting'.
