Abstract
A method comprises providing a change to apply to video; dividing video into blocks; creating propagation map which captures only specific changes to blocks that would be changed by the application of the change; evaluating the change based on a luminance criterion as being a perceptible change or an imperceptible change; for propagation maps of an imperceptible change, storing the propagation map to a list, wherein the propagation map is the principle data structure to be applied to the video. The propagation map can be created by using motion vector changes associated with the change.
