A method of creating a binary animation file commences with the step of selecting an initial image and subsequent images having pixels. The color pallet of the initial image (having n indexes) in converted to a colour pallet having n-1 indexes so that one of the n indexes is used as a mask index. Second and subsequent images are determined and are used to define a frameset which begins with the initial image and defines a sequence of images. The initial image is compressed using Run Length Encoding and stored to a movie file. Using the mask index, a new data array is created for the second and subsequent images. The second image is compared to the initial image on a pixel by pixel basis. The method requires the storing of differences between the first and second images in the form of difference data to the movie file, the difference data comprising an array of bytes that represents a Run Length Encoded compressed description.
