In building a animation we often provide a animatic for the client. A simple explanation of a animatic is a storyboard in motion with simple zooms and pans to simulate camera movement. Animatics are animated video storyboards. This is the stage that we do the timing of the images with simple motion.
In a .60 sec. animation this helps to determine the length of the section and where the time should be spent on telling the story. www.binaryrecordingstudio.com
Sometimes the sound effects or soundtrack are included to give the client a feel of the piece. This is a inexpensive way to test the animation before all the elements are added.
Below a example of a motion comic we produced from still image drawings.
