The Preview Window

The Preview window allows you to preview either a ramp or an offspeed. A ramp preview will apply
the fps changes defined in the Ramp Editor to a movie, thus allowing you to see what this ramp will
look like once it is filmed. An offspeed preview allows you to see what the movie would look like if the
film camera would have run at a different (but constant) speed.
