The processor is responsive to the stylus/touch tablet to generate data representing a time-based function defining the manner in which a parameter of the video clip varies with the time of the clip. The processor is arranged to generate data for display on the monitor of a graph representing the plot of the function. The processor also responds to operation of the stylus/touch tablet device by manipulating the graph data for display so as to zoom into or out from a portion of the plot.
