This is an example where I set the rate to 5 units per second. The lower the rate, the longer it will for the animation to run from start to end r = 1; step = 0.1; backgroundAxes = Plot[0, {x, -Pi, 3*Pi}, PlotRange -> {Automatic, {-r/2, 2*r + 0.5}}, AspectRatio -> Automatic]; Animate[Show[{backgroundAxes, ListPlot[Table[{x - Sin[x], 1 - Cos[x]}, {x, 0, t, step}], Joined -> True], Graphics[{PointSize[Large], Red, Point[{t - Sin[t], 1 - Cos[t]}]}], Graphics[Circle[{t, 1}, r]]}], {t, 0, 2*Pi, step}, AnimationRate -> 5] Export["test.avi", p] --Nasser
