I would post the source or the .exe file(again) but this section has no minions so I'm not going to even bother. >_>

Really HQ post! what kind of quality does this make? i usually record a video and edit it in photoshop, so quality loss isnt really a problem.

I don't have to handle the quality or compression of images because I'm retarded and don't know how to program. If you want to lower your file size and or handle the quality. You'll probably want to do it with the image files not the actual gif output. But I don't know
