I have a sequence of images 001.png 002.png 003.png that I would like to combine into an animation.

I used the following command

convert -dispose 3 -loop 0 *.png out.gif

And it looks ok. However, when I tried this

convert -dispose 3 -loop 0 "001.png" "002.png" "003.png" out2.gif

out2.gif was not as "smooth" as out.gif.

Why is there a difference in the output between the two commands, which seem to mean the same thing?
