NetLogo create-movie: speed is too fast when played from file

So I wrote a NetLogo (v6.3) program. Now I would like to record a video to be embedded within a powerpoint presentation. Here I found the following code that does this:

extensions [vid]

to make-movie

  setup
 vid:start-recorder
 vid:record-interface ;; show the initial state
 repeat 2
 [ go
   vid:record-view ]
 vid:save-recording "out.mp4"

end

But upon playing the created .mp4 file using QuickTime, i notice that the speed is much faster than shown in NetLogo. It's too fast (or faster than I'd like) to be shown in a powerpoint when presenting to a group of people. Has anyone experienced this too, and what could be a workaround this?

  • At http://ccl.northwestern.edu/netlogo/docs/programming.html#movies it says:

    A movie will play back at 25 frames per second. To make the movie playback faster or slower, consider using a video postprocessing tool.
