Hi there,

i have a skript with an animation as output. i want to automatically save the animation as an video file on my laptop. what do i need to do?

thanks a lot for your help.

I had a great experience using gif from the file exchange to convert a series of plots into a gif-animation. Simple to use does what it says on the tin, gif-file reasonably sized. The file exchange it the place to look for solutions to your problems - most of the time you'll find something that solves or partly solves your problem or at least helps significantly towards a solution.
