The button batch conversion in the Image2Ascii tool is intended for converting multiple image files (gif, jpg and some bmp formats are supported) to an ASCII animation.
And here is how it works:
Wherexxxxxxx00.jpg xxxxxxx01.jpg xxxxxxx02.jpg ...
xxxxxxxmay be any characters but ciffers. You can also leave out leading
0s from the frame numbers.
The JMOV file can then be edited and viewed using the movie editor in JavE or using the open source JavE Player applet.
There are some simple example movies online (Demo 3 is movie that has been created using the description above).
Unfortunately you can not use JavE to extract frames from mpeg/avi animations - so you have to figure out how to do this with other tools. I do not know about those tools, but if you find a good one please let me know.
