An animation is simply a series of images shown in order, one at a time. The number of images per unit of time determines the speed of the movie, a factor usually referred to as the ''framerate''. For instance, if we generate 300 images, we can create a 10-second movie at 30 frames per second, or a 20-second movie at 15 frames per second. | An animation is simply a series of images shown in order, one at a time.

Introduction
If you wish to make an animation in your document, see the Animation page. This page will explain how to MetaFun_-_MetaPost_in_ConTeXt to create a mp4 movie. Such movie can be embedded in a presentation, put on YouTube, etc, this will be a real movie !
The steps involved to realize such a movie are to (1) make a pdf such as each page is a frame of the movie, (2) convert the pdf pages to jpeg images, (3) assemble these images into a mp4 movie.
Tutorial
An animation is simply a series of images shown in order, one at a time. The number of images per unit of time determines the speed of the movie, a factor usually referred to as the framerate. For instance, if we generate 300 images, we can create a 10-second movie at 30 frames per second, or a 20-second movie at 15 frames per second.
This tutorial will be to design and animate a movie showing particles moving along circles. The different images needed for the animation will be pages from the same PDF. The general structure of the code is as follows:
\starttext \dorecurse{300}{ % Each of the 300 images \startMPpage % Insert here code to draw an image \stopMPpage } \stoptext
