Codec Lecture

This is a lecture on Codecs. Why we compress and decompress and what is really happening with shrinking the size of our videos.
We talk about Picture, Audio, color, and frame. and how codecs interrupt that information to make online video look good and deliver smoothly for youtube and elsewhere.
Compression is a balance of Quality and file size.
This is part of a class I teach at Weber State University.

The video we watch at the end can be found here... http://www.youtube.com/watch?v=2cbXxyr0DCY ... though some of the info is a little outdated now. ;)
