The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file.
%MPGREAD Read an MPEG encoded movie file.
% [M, map] = mpgread('filename', frames) reads the specifed
% MPEG file and translates it into the movie M, and colormap map.
% If a vector frames is specified, then only the frames specified
% in this vector will be placed in M. Otherwise, all frames will
% be placed in M.
% M = mpgread('filename', frames, 'indexed')
% Reads an MPEG file into the MATLAB 5.3+ format movie which
% is a structure array. Each element has a cdata field
% containing a uint8 image matrix and a colormap field
% containing the colormap. The frames parameter can be  to
% indicate that all frames should be read.
% M = mpgread('filename', frames, 'truecolor')
% Reads an MPEG file into the MATLAB 5.3+ format movie. Each
% frame in the movie has a truecolor MxNx3 cdata field and
% an empty colormap field.
% [R, G, B] = mpgread('filename', frames) will perform the same
% operation as above, except that the decoded MPEG frames will
% be placed into the matrices R, G, B, where R contains the red
% component for each frame, G, the green component, and B, the
% blue component.
