This feature allows the user to create a sequence of images that can then be joined together into a video file by another application. There are several freeware and open-source packages that will do this, I would suggest ffmpeg. Ffmpeg is open-source and many other packages use it as their video engine. The only down-side is that it is command line.
This animator is very different than those you might find in other packages. Most other packages allow you to select a start image and an end image and it fills in the middle images. Some other packages incorporate an animation time-line similar to those found in model and animation editors like Blender. The one built into this program uses equations and variables to alter the formula settings.
At the top you will see a panel that is like the Generating Formula and Options panel of the program. The only difference is that the Maximum Iteration is now an editable text box and not a "spinner". There ia also a box for the Interpolation Degree that is used by some of the color schemes. Below that are a list of variables, each has a beginning and ending value as well as an option to increment the variable in a linear fashion or exponential fashion. At the bottom is a panel to select a base filename, the number of frames to be generated, and the file type.
For example, say you wanted to animate z^2 + c to z^3 + c, that is, see what happens as the exponent goes from 2 to 3. Just set the formula to z^k + c, give k a beginning value of 2 and ending value of 3 and a linear increment.
Another example, say you wanted to animate an image as you zoom in on a point. Set the width to k, give k a beginning value of 5 and ending value of 0.0001 and an exponential increment.
The color scheme that is used is the one defined by the current selection in the Color Scheme panel. The only alteration to the color scheme is the Interpolation Degree, if the scheme uses it and you have put in a formula for it. In the case of the maximum iteration, the formula for it will be rounded to the nearest integer.
