Computers and video cameras

Computers and video cameras in traditional cel animation can also be used as tools 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 the old original way. And video cameras gives the opportunity to see a "sneak preview" of the scenes and how they will look when finished, enabling the animators to correct and improve them without having to complete them first. This can be considered a digital form of pencil testing.
