Hi, Mathematica for PC can save as GIF (when saving a sequence of plots, that means aGIF (A for animated)). You can use other program (e.g. Animation Shop) to convert aGIF into AVI. How to make aGIF under Mathematica? e.g. MakeAGif[name_String, src_] := ( SetDirectory["D:\!Users\Borut"]; Export[name, src, "GIF", ConversionOptions -> { "Transparency" -> RGBColor[1, 1, 1], "Disposal" -> Background, "Loop" -> True} ] // Timing ); I would like to mention the slowness of Mathematica saving sequential GIFs. Very slow! Why's that? Mathematic for MAC, as far as I know (I don't posses it), is able to save animations as MOV (QuickTime). I heard there are inovative designs engaged for next Mathematica graphics userface. Is this so? Well, bye!
