IM is not really will suited to generating MPG and other movie formats.

I suggest you use mmencode  instead, whcih is really designed for this
type of thing.  IM can still be used for processing though, and a lot of
movie processing packages use it for this purpose.

You could try the m2v format...

   convert -delay 10 *.jpg m2v:glacier.mpg

Another example I have is..

   png2yuv -j file%08d.png -I p -f 25 -b 1 | \
       mpeg2enc -f 3 -q 3 -b 5000 -o out.m2v

I saved thes into IM Examples, for MPEG format at
   http://imagemagick.org/Usage/formats/#mpeg

Also present in this area was the following notice...

    There are some reports that unless the images are the right aspect
    ratio is correct this will fail on older mpeg players, use the MPEG
    II extension (m2v:) instead.
