Grapher is awesome is so many ways, but the animation output is huge. I have a set of ~15 parameters that feed into two equations that describe two (2D) ellipses. The two ellipses are the only things I plot. But when I do a simple 10-frame animation of one of the underlying parameters, the animation file is 100+ MB. (Strangely, when I did more frames, the size was ~55 MB.) That means I can't use it in any presentation. Also, when I use QuickTime and try to export to lower resolution, I get "The operation could not be completed: an unknown error occurred." Any suggestions on how to manage the size down to ~5 MB or less? Thanks much.
