Animated GIFs

Animated GIFs can be made from a collection of still images using FFmpeg. First create a sequence of bitmap images, as discussed on the OOMMF Movie page. Then run a command like

ffmpeg -start_number 0 -i stdprob4a-%07d.png -r 25 -loop -1 stdprob4a-div.gif

The “-loop -1” option sets the animation to run one time, with no looping. The output files are 36 MB for part (a) and 42 MB for part (b).

Your browser should start the animations below when you move your mouse over the image.
