Hi, Murat, I propose that you export Animate, rather than Manipulate. In this case you get several options controlling your movie. In particular, I would recommend to use the following options: AnimationRate -> M, DisplayAllSteps -> True, AnimationDirection ->Forward, AnimationRunning -> True in the operator Animate. If the animation parameter runs from 1 to K with step 1, you determine M as K/M=30. The panel may be removed by the option Paneled->False. Mathematica does not like this option and often marks it in red, but obeys though. How to remove a slider when using Animate or Manipulate - is a good question. I do not know. There is an alternative possibility, which I prefer. You may create a table of graphics and then directly export it as say, avi file. In this case you may use the option "FrameRate"->P of the operator Export which then creates a movie with P frames per second. Then you may easily calculate P to make the movie duration equal to 30 seconds by knowing the total number of the graphs in your table. Just to illustrate: (* Begin of an example *) (* This is a function to show: *) z2[x_, y_] := (1 - 0.62*y/Power[x^2 + y^2, (4)^-1])* Exp[-0.15*Sqrt[x^2 + y^2]]; (* This is the definition of an image. Here v is a parameter both changing and enumerating different images *) image[v_] := Plot3D[3*z2[x, y]*(1 - v^2)*Exp[-0.15*x*v], {x, -10, 4}, {y, -4, 4}, PlotStyle -> {Opacity[0.9]}, PlotRange -> {{-10, 4}, {-4, 4}, {0, 5}}, AspectRatio -> 0.8, ColorFunction -> "Rainbow", Mesh -> None, Boxed -> False, Ticks -> None, AxesLabel -> {"x", "y", "\[Eta]"}, AxesStyle -> Directive[Large], ViewPoint -> {15*Sin[1.4]*Cos[-2.5 Pi/4], 15 Sin[1.4]*Sin[-2.5 Pi/4], 15*Cos[1.4]}, ImageSize -> 500]; (* This creates a table of 40 images. Here you play with its length *) a3 = Table[image[v], {v, 0, 1, 0.025}]; (* This exports the table as an avi file which theoretically should play 40/3=13 seconds *) (* Play with the FrameRate here *) Export["Full_path_to_your_target_folder\a3.avi", a3, "FrameRate" -> 3] (* End of the example *) As the result you will get in your target folder a stay-alone a3.avi file without any panel or slider. Just copy and try up. Another such example has been already discussed concerning rotation of a 3D graphics. You may find it here: http://forums.wolfram.com/mathgroup/archive/2008/Nov/msg00197.html Have fun :-) , Alexei I successfully created a movie using_ Export[=E2=80=9Cmovie.avi=E2=80=9D,data,=E2=80=9D AnimationDuration=E2=80= =9D->30] data is actually a Manipulate command; data=Manipulate[GraphicsColumn[ {A[[i]],B[[i]]} ,{i,1,dim,1}] However, I haven't figured out; 1) showing only the forward loop of the movie in 30 sec (AnimationDuration). Export automatically creates forward and backward sequences and 2) I don't want to include any Sliders in the movie for presentatio n purposes (like in the Hide Controls option). Do you know which commands I should add to reach my goal in the Export or Manipulate command? I searched the Documentation Center and MathGroupArchive but I couldn't come up with the answer. I am currently using V6.0 although my institution has all the licenses including V7. I am waiting for a new machine to separately run V7 if it has the necessary options.
