what platform are you running on, what movie trype do you use (gif or mpeg)
and how many frames does your trajectory have?

in the movie generator there is a menu 'Movie Settings' where you can
select Image Smoothing and Half-Size rescaling.

note, that if you require high quality images, an animated gif is usually
the nicer movie (provided you have only a few frames). for longer trajectories
gif movies can become huge (especially when using the convert tool on
linux/unix machines. which does not do any inter-frame optimization).
mpeg movies have usually a lesser quality but can
accomodate many more frames in the same space.

hope that helps,
