I am exporting an animation created using Manipulate in the .avi format. However the video runs very fast (I am putting it in Keynote). Its speed seems independent of how small I choose the step in Manipulate. Is there a way to control how fast the .avi will run or some other way to show the animation slower?


The trick is using a combination of "FrameRate", an option of Export, and AutorunSequencing, an option of Manipulate. The former determines the number of frames/second of the movie whereas the latter determines how long a sweep of the control takes. With one control, that will be the length of the movie.

   Plot[Sin[k  x], {x, 0, 2 \[Pi]}], 
   {k, 1, 5}, 
   AutorunSequencing -> {{1, 10}}
 ], "FrameRate" -> 2

enter image description here

    $\begingroup$ Actually the FrameRate will not control the speed of sliderbar's velocity.Just take frame form oringnal fast video. $\endgroup$ – yode Oct 15 '15 at 2:57

  • $\begingroup$ What happens when I need FrameRate to be 0.5? To have a picture for 2seconds for example? I did not work for me. $\endgroup$ – Chen Stats Yu Aug 31 '18 at 2:28

The option you need is "FrameRate". It's not even necessary to create a list of graphics objects first, as per Sjored's answer.

  • $\begingroup$ You can Export a Manipulate as movie without creating an array. Try Export["output.avi", Manipulate[Plot[Sin[k x], {x, 0, 2 \[Pi]}], {k, 1, 5}]] $\endgroup$ – Sjoerd C. de Vries May 14 '12 at 19:44
  • $\begingroup$ @SjoerdC.deVries: but you can't control the speed of the movie that way afaik. $\endgroup$ – Heike May 14 '12 at 19:46
  • $\begingroup$ @heike please see my answer $\endgroup$ – Sjoerd C. de Vries May 14 '12 at 20:06
  • $\begingroup$ @SjoerdC.deVries I stand corrected $\endgroup$ – Heike May 14 '12 at 20:21
  • $\begingroup$ @SjoerdC.deVries Me too:) $\endgroup$ – Ajasja May 14 '12 at 20:30

I've found that giving the option "AnimationDuration"-> (seconds) in the Export function gives better results generally.

    $\begingroup$ Please elaborate on your answer. For instance, in what sense does "AnimationDuration" give better results? $\endgroup$ – bbgodfrey Oct 14 '15 at 14:50
  • $\begingroup$ @bbgodfrey Rather than reducing the framerate, it gives a longer animation at the same framretae, making it smoother. $\endgroup$ – RationalAsh Oct 16 '15 at 8:38
  • $\begingroup$ I don't see this as an options at all $\endgroup$ – soandos Nov 24 '16 at 17:31
