I assume that you are trying to make an MPEG video from a series of rgb
screen captures. I have not tried dmconvert, but the Computer Science
Division at the University of California at Berkeley has a set of MPEG
tools on their web site :

  ftp://mm-ftp.cs.berkeley.edu/pub/multimedia/mpeg/bmt1r2.tar.gz

The gzipped (make suer you have gunzip*) tar file is ~8 MB. It has both
an encoder, a decoder and some other diagnostic programs. I used the
mpeg_encode routine to build an MPEG video from rgb screen captures. It
works well, but it may take a little bit of time to figure out how to use
the encoder properly. You would also need to compile rgb.c (I believe it
is part of your IRIX 5.3 operating system) into an executable to convert
the images into a format that the encoder can read.
