New projects are unlikely to be based on MPEG-1. This was a popular codec when deploying video on CD-ROMs and is also used in games design.
10.2 How It Is Done in MPEG-1
The simplest of the MPEG video-compression formats is the best place to start. The others are all based on this model and just add some enhancements.
