To composte over a sequence of images, you need to use the "-draw image" method.
I don't have an actual example of compositing onto animations at this time, as I am waiting time to creat a few extra (and better) image sequence layer methods for alpha composition.
Hmmm something like this...
Code: Select all
convert animation.gif -coalesce \
-draw 'image over 20,30 0,0 "overlay.png"' \
-layers optimize animation_overlayed.gif
