This phase is composed of Story, Storyboarding, Visual Development and Previs. Story is the essence of the animation which is being produced and is called vision of the film. In this step, a script is developed and will be the reference for the whole production process. The script is broken down into scenes in Storyboarding step, which allows the director to envisage the final product in order to make necessary modifications at the early stage of the project.
Within an editorial step of the pre-production, a reel consist of the storyboard images, temporary music and scratch voices will be produced which becomes the foundation of the animation. Furthermore, characters, environments, color pallets and backgrounds will be designed in the Visual Development step in order to illuminate the path to the final product. Previs or Pre-Visualization is where the rough output consists of storyboards, characters, environments and backgrounds is produced which can be used directly to produce animation.
