record image effects as animations

Question

I've done only some very basic stuff with ImageMagick (mainly resizing, also messing with color filters a bit).

Imagemagick has a simple example for overlaying images:

  convert anthony_1.jpg anthony_2.jpg -average  anthony_ghosts.jpg

But I have no idea how to do this in an animated way. An example (with explanation) for ImageMagick or another program would be appreciated.

I'm no ImageMagick expert either, so there must be better than this example:

convert -pointsize 72 label:ByeBye -resize 300x100! /tmp/b.gif
convert -pointsize 72 label:Hello -resize 300x100! /tmp/a.gif
for i in $(seq 10)
do   composite -blend ${i}0 /tmp/b.gif /tmp/a.gif /tmp/c${i}0.gif
done
convert -delay 50 -dispose None /tmp/c?0.gif /tmp/c100.gif -loop 3 /tmp/out.gif
display /tmp/out.gif

We create 2 small gifs holding some text, then use -blend with a value of 10% to 100% to create files c10.gif to c100.gif. These are joined into an animation with a delay of 50/100th seconds per frame, looping 3 times. See animation and compose.
