I use UnFREEz too...But, how do you make it so the image is still so clear? I use paint to save the frames, and then I bring them into unFREEz, and they come out wrong, because savingthem as a GIF messes with the color...
Hmm... would you have a way to give me your GIF frames? if you want I can try to finish it for you ^^ You could host them on ImagesShack if you want, and I'll see what I can do I am French so I do not understand the entirety of your message but I realized there was a problem during the final assembly x)
I used the software Photofiltre (name in French, Photofilter in English I think) to make every frame, and then I make gif with with UnFREEz (they are both free ^^)
