Hello, I am using Animate command, and then trying to export the animation in video mp4 format. In the Animate command I used

VDO = Animate[ ......, AnimationRate -> .01, AnimationRunning -> True, AnimationRepetitions ->
  1,AppearanceElements -> {"StepLeftButton", "StepRightButton", 
     "PlayPauseButton", "DirectionButton"}]

and

Export["OrbitVdo2.mp4", VDO, "FrameRate" -> 10, 
 "AnimationDuration" -> 16]

The Animation shown in Mathematica is coming correctly with only once running in forward, but the exported mp4 file is very fast and even though I have used Animation Repetitions as 1, in video it take forward and reverse animation. And the animation starts after half time of Animation Duration i.e. if I choose 16 second video then after 8 seconds, animation starts in video. If its 20sec, then animation starts after 10sec.

Please give me solution, how to extract video in mp4 similar to Animation in Mathematica. Thank you.
