Animatics have increasingly become the standard. Often storyboards are edited into small movies that sometimes just combine the images with audio and a timeline.  Sometimes, however, animatics require elaborate processing and many moveable elements in the form of Photoshop layers (Arms, legs, mouths, foreground, background e.g.). The result gives an idea of the final film and can be played to a test audience, for example. Since I did not do the programming on these Animatics, a good part of the credit goes to the co-working people on these projects!
