I am using the VMD Movie Maker plug-in with VMD 1.8.6 to generate MPG movies
of simulation trajectories. Behind the scenes, the TCL script uses PPMTOMPEG
to stitch the individual PPM images into an MPG file and I am wondering
which settings in the PPMTOMPEG parameter file (.par) can be toggled to
achieve better quality movies (presumably at the expense of compression)? I
find that, with the default settings, the output MPG movie is rather
'grainy'.

Many thanks!
