There's much more to visual communication than simply slapping a series of shots together. With video, you need to think about the way you connect your shots.
In the February 2010 issue of Videomaker, we featured an article asking, What is a CODEC?

This article presents a codec "state of the union" as it were, a revisit of some of the basics as we dig just a bit deeper into this ever-growing topic. We'll explore the variety of codecs available within two distinct families, Apple ProRes and the MPEG family. We'll also look at effective media management through the use of these codecs, and more.
