Slow down this animation, while exporting into a .mov file?

Posted 8 years ago

Hi, could you please help me out, i want to slow down this animation when i export it into a *.mov file. Regards

v = Manipulate[
  bas = Graphics3D[{Opacity[.1], Cylinder[{{0, 0, -1}, {0, 0, 1}}, 1],
      Opacity[.3], Cone[{{0, 0, -1}, {0, 0, 0}}], 
     EdgeForm[{Thick, Red}], Red, Cone[{{0, 0, 1}, {0, 0, 0}}]}, 
    ViewPoint -> {Pi, Pi/2, 2}, Boxed -> False, 
    AspectRatio -> Automatic, ImageSize -> 200];
  bas1 = Graphics3D[{Opacity[.1], 
     Cylinder[{{0, 0, -1}, {0, 0, 1}}, 1]}, 
    ViewPoint -> {Pi, Pi/2, 2}, Boxed -> False, 
    AspectRatio -> Automatic, ImageSize -> 200];
  b = Graphics3D[{Blue, 
     Table[Cylinder[{{0, 0, x}, {0, 0, x + 0.1}}, x], {x, 0, r, 
       0.1}]}, AspectRatio -> Automatic, ImageSize -> 200];
  a = Graphics3D[{Green, 
     Table[Cylinder[{{0, 0, x}, {0, 0, x + 0.1}}, Sqrt[1 - x^2]], {x, 
       0, r, 0.1}]}, ViewPoint -> {Pi, Pi/2, 2}, Boxed -> False, 
    AspectRatio -> Automatic, ImageSize -> 200];
  d = Table[
    Graphics[{Red, Disk[{0, 0}, {1, 1}], Blue, Disk[{0, 0}, {x, x}]}, 
     AspectRatio -> Automatic, ImageSize -> 130], {x, 0, r, 0.1}];
  c = Table[
    Graphics[{Green, Disk[{0, 0}, Sqrt[1 - x^2]]}, 
     AspectRatio -> Automatic, ImageSize -> 130, 
     PlotRange -> 1], {x, {r}}];
  Row[{Show[bas, b], Show[d], Show[c], Show[bas1, a]}], {r, 0, 0.9}]


Export["movie.mov", v]

I never have used Export for this -- I use a screen capture program to export video either as a .mov or an animated gif (if I am posting it to this site)

The documentation for Exporting video is here. I tried changing the FrameRate and that did not work. Changing the VideoEncoding to something better (like Apple ProRes 422) makes a better video. However, I was not able to change the speed. You can experiment with the options or try GIF or one of the other video formats mentioned in the documentation.

Maybe someone else has done this before and can answer this...

Regards

Hi Neil, I've converted manipulate into animate and set the animation rate to 0.1. now it's working perfectly fine in mathematica, but when i export that animation into a .MOV file it is still very fast. Could you please help me out with this? I'm attaching the mov file and nb file.
