Editing Traditional animation (section)

==Computers and digital video cameras==
Among the most common types of animation rostrum cameras was the Oxberry. Such cameras were always made of black anodized aluminum, and commonly had 2 peg bars, 1 at the top and 1 at the bottom of the lightbox. The Oxberry Master Series had 4 peg bars, 2 above and 2 below, and sometimes used a "floating peg bar" as well. The height of the column on which the camera was mounted determined the amount of zoom achievable on a piece of artwork. Such cameras were massive mechanical affairs that might weigh close to a ton and take hours to break down or set up.

In the later years of the animation rostrum camera, stepper motors controlled by computers were attached to the various axes of movement of the camera, thus saving many hours of hand cranking by human operators. Gradually, motion control techniques were adopted throughout the industry.

Digital ink and paint processes gradually made these traditional animation techniques and equipment obsolete.

Computers and digital video cameras can also be used as tools in traditional cel animation without affecting the film directly, assisting the animators in their work and making the whole process faster and easier. Doing the layouts on a computer is much more effective than doing it by traditional methods.{{sfn|Laybourne|1998|p=241}} Additionally, video cameras give the opportunity to see a "preview" of the scenes and how they will look when finished, enabling the animators to correct and improve upon them without having to complete them first. This can be considered a digital form of ''pencil testing''.

The final animated film by Disney that featured the use of their multiplane camera was ''[[The Little Mermaid (1989 film)|The Little Mermaid]]'', though the work was outsourced as Disney's equipment was inoperative at the time.<ref>{{Cite journal |last1=Musker |first1=John |last2=Clements |first2=Ron |date=2010 |title=Aladdin |journal=100 Animated Feature Films |doi=10.5040/9781838710514.0007 |isbn=9781838710514}}</ref> Usage of the multiplane camera or similar devices declined due to production costs and the rise of digital animation. Beginning largely with the use of [[Computer Animation Production System|CAPS]], digital multiplane cameras would help streamline the process of adding layers and depth to animated scenes.
