Abstract:
A method for processing a digital video image to provide a desired video effect, which comprises: a) selecting values of parameters that are to govern the course of said effect during the time period of a corresponding scene to be displayed, b) storing said values of said parameters with reference to time, at defined points in said time period spaced from on another in such a manner that the desired course of each said parameter can be interpolated from the stored values for the reproduction of video image frames occurring between the defined points of said time period, and c) causing said stored values to be retrieved and interpolated by a digital video effects apparatus during reproduction of a digital video signal in order to reproduce the desired effect, whereby step (b) comprises storing values of each of at least some of said parameters independently of other parameters in a time line exclusive to that parameter, whereby the position of the defined point at which any value is stored in the time line, and/or the value of a stored parameter at said point can be adjusted independently of the other parameters.
