We have all watched animated movies and cartoons and enjoyed them. There may also have been a time when we wondered how these were made. The 2D animation process is quite simple and uses the same concept that makes regular movies. This is the persistence of vision, which is the ability of the brain to fill up gaps between two images if they are shown at a rapid rate. While movies use still photographs to do this, animation uses illustrations.
With 24 frames to a second, the 2D animation process can be quite long and expensive. This is why the pre-production planning of these movies is very important. The 2D animation process pre-planning starts with the storyboard and not with a script. The script is simply a written description of the scenes and dialogues while animation needs more visual planning. The storyboard, on the other hand, is like a comic book and visually describes each scene.
The next part of the 2D animation process varies in the different parts of the world. Some prefer to record the sounds and dialogues and then animate the movie based on them, while others like to make the animation before the actors record the dialogues, which are synced with the movement of the animation.
The 2D animation process of production involves the creation of each frame, which is now done by computer. The process was made very easy by Disney Studios with the invention of the Cel Technology where the stationary elements of the scene are kept constant while the moving elements are created on separate transparent celluloid sheets. This way, the active elements can be shot together with the passive elements, without having to repeat those.
