Overview
This white paper is intended to help the reader understand the roles and benefit of both the MJPEG and
the MPEG-4 compression methods, and when to use which one based on necessity and performance. It
begins with some basic concepts that relate to both image size (in pixels) and PPF (pixels per foot).
This is followed by some background information on compression: why it was needed, and how it is
accomplished; finally, each compression method is described separately, listing the key advantages of
each.
