Apple Motion 4 - Manual (Page 289)

Compositing is the process of combining at least two images to produce an integrated
final result. The process can be as simple as placing text over an image, or as complex as
combining live actors with drooling space aliens that shoot laser beams from their eyes.
Motion graphics artists move multiple objects simultaneously onscreen using a strong
sense of visual design. Motion graphics artists typically use techniques such as changing
group and object order, transforming the physical properties of objects (such as scale),
adjusting object opacity and blend mode settings, applying filters to objects, and creating
text and shapes. Motion graphics projects often combine layout and design techniques
with techniques borrowed from special effects work such as keying, masking, color
correction, and creation of particle systems.
