Sam,
  The easiest way to deal with this is to duplicate trajectory frames.
You can write a simple VMD script to load your original trajectory
into one molecule, and then build a second molecule, duplicating
each of your 50 frames N times, for whatever value of N makes the
movie playback speed most appropriate for your needs. Since the movie
formats use hard-coded frame rates in the range of 24 to 30 frames
per second, you'll probably want to duplicate each frame something like
4 to 6 times so that you end up with a movie that's say 6 to 12 seconds
long (depending on movie frame rate and number of frame dups) as a starter.

Cheers,
  John Stone

When I try to make a movie, it goes through the entire motion very quickly, then lingers on the last frame for the remaining time. Is there a way to slow down the motion? I could generate GIFs and then concatenate those using convert, but I wonder if there's an easier way within VMD.
