I love GifCam.
Easy and handy to use for create animated gif from capture.
For the fun, i have tried to do it in AutoIt.
GifSicle is only used for compress animated Gif when saving or decompress when loading.
Due to a lack of time, I have not re-created all the features of latest GifCam Version.
Warning : Use latest AutoIt release (v188.8.131.52) and script do not work under XP.
source and executable are available in the Download Section
