Abstract
A digital video effects system for emulating motion blurring includes a digital video effects apparatus for manipulating an input image to generate an effect, and a controller for controlling the apparatus to generate an output image sequence comprising a sequence of output images at respective output image timings in which different manipulations are applied for successive images such that the effect changes with time. The controller causes the apparatus to combine a set of constituent images for each output image, the constituent images manifesting manipulations commensurate with respective constituent image timings. The constituent images for each set of constituent images are combined to form a respective output image in the output image sequence.
