Abstract:
A method of converting a video file to a Graphics Interchange Format (GIF) image includes converting a plurality of frames of a video file into corresponding frames of a GIF image, creating a first palette table for defining colors in each frame of a first set of consecutive frames of the GIF image, and creating a second palette table for defining colors in each frame of a second set of consecutive frames of the GIF image, wherein the first palette table is not equal to the second palette table and each frame in the first set of consecutive frames is distinct from each frame in the second set of consecutive frames.
