GIF'ted

GIF'ted is an application that lets you turn your MPEG-4 movies into sleek animated GIFs in no time.

GIF’ted will analyze all the frames in your movie to create the proper 8-bit palette. This makes your GIF’s looks smooth and nice. Optionally, you can use classic palettes from Gameboy or SNES to give your GIF’s a special look. In addition, you can record your screen using QuickTime Player and turn your screencast into an animated GIF.
