AnimationDirection when Exporting

Suppose I want to export an animation (using Animate or Manipulate) so that the exported animation runs once in the forward direction and stops. Here's a little example, of a circle moving from left to right along the x-axis. anim = Animate[ ParametricPlot[{Cos[t] + k, Sin[t]}, {t, 0, 2 Pi}, PlotRange -> 10], {k, -12, 12}] Export["anim.avi",anim] In the resulting AVI, the circle moves from left to right (the desired Forward direction), and then it runs Backward, from right to left. One would think that setting AnimationDirection->Forward would fix this. So try exporting this: Animate[ ParametricPlot[{Cos[t] + k, Sin[t]}, {t, 0, 2 Pi}, PlotRange -> 10], {k, -12, 12},AnimationDirection -> Forward] It still runs once Forward, then once Backward. I've also tried specifying the direction within Export. Export["anim.avi",anim,"AnimationDirection" -> Forward] Still no joy. Is there any way to get the exported animation to run once in the Forward direction only? This has been a nagging issue for me for quite some time. -- Helen Read University of Vermont
