G.1 MPEG-4 Complexity
MPEG-4 is far more complex than earlier video codecs. Indeed, the video coding is expressed only in Parts 2 and 10 of the standard, and these describe two completely separate codecs.

The H.264 standards group defines a rather smaller set and hence the MPEG-4 Part 10 coding is also simpler. Those will be described separately from MPEG-4 Part 2.
Profiles are intended to define a set of tools that are available, and levels define the range of appropriate values for the properties associated with them.
