1. A method of editing a compressed input image sequence and producing therefrom a compressed output image sequence, the input sequence including at least one group of images (that does not depend upon any other images for reconstruction from a compressed format), the group of images having at least one compressed dependent frame that contains data for reconstructing one image based upon data from a second image in the group of images, said method using a computing device and comprising:

  • receiving with the compressed input image sequence;

    using the computing device to convert a dependent frame to a compressed data format that does not depend upon the second image without decompressing all images in the group of images to an image domain;

    editing data using the computing device, by altering temporal order of an image represented by the dependent frame with respect to at least one other image in the sequence; and

    using the computing device to produce the compressed output image sequence from the data which has been edited by the computing device.
