one option would be to hack the movimaker script to use each VMD frame
multiple times. another option would be to keep the intermediate images
and then use some shell scripting to create copies (or symbolic links),
which have to be properly numbered. also you can use vmd scripting to
generate the additional frames for your trajectory (which would also
allow you to apply interpolation) to make the movie smoother, but
the scripting a little more involved.

that would only work, if you have the frames in individual files.
where you then have to load each frame multiple times.

the animation speed in VMD has no impact on the movie. the length and
speed of the movie is determined by the number of frames and the delay
between them. as written before: in mpeg this delay is fixed (and rather
