So where does it start? To create an animation, there needs to be a story line or a plot. In Japan's case, usually the manga artists provides the plot and character outlines needed in order to create the anime. In combination to this, the manga has to be popular enough, in order that production companies and producers are willing to fund and create the anime. Directors and animators are then chosen to create the anime and the manga artist is there to supervise and put forth info in order to display the story in a way that represents the manga artist's vision, as well as an entertainment that attracts and appeals to an audience. Writers are chosen to create the episode-by-episode scripts, which are then review by the entire animation team. Revisions often occur during this stage and in order to ensure both the author's and the director's vision of the anime, the storyboard is created.
A storyboard creates a frame-by-frame work of the anime. Along with this, it details the actions and the dialogues of the characters and describes the setting or the scenery. With a limited budget creates constrain on everyone, so it limits the amount frames to display. Each frame is chosen carefully and many cuts and revisions are made to present the core action of the manga (for this reason, many people prefer manga to anime). Developing layouts marks the transition into the art production phase. The background is set, the actions of the characters are defined, and the frames are shaped to the same size. Colors are chosen to represent the frames in this process. Other decisions that are made include the angle of the shot and the position of the character.
All of the animation in anime is hand-drawn, but nowadays, animators draw directly onto a computer. This helps by checking the frame-by-frame work for any mistakes during the process. Here is a video detailing this. This process first starts the characters off as "stick figures," then it gradually develops the details of the character (such as the character's expressions). The animators then detail the setting. In-between animators then come in and make the movements of the characters more fluid, rather than a frame-by-frame montage.
The frames are then colored and processed and special effects and added on. The last stage of this process is adding on the voice dubs and composing the music, but other than that, the animation process is completed!
