Basic and typical batch operations to carry out on still frames before rendering them into a movie:

First, I keep (here) the upper 84% part, to crop an uninteresting bottom part:

convert imageSequence00000079.jpg -crop 100%x84%+0+0 cropped-imageSequence00000079.jpg

Then I highlight the colors with aaphoto:

for f in *.jpg; do aaphoto -a --overwrite "$f"; done
