Abstract
A digital video effects apparatus is arranged to generate a digital video effect by interpolating the values of parameters governing the effect, according to a given function, between time points corresponding to selected frames of a video signal and at which the parameters are fixed at selected values. The apparatus is organised in such a manner that the values of parameters are stored in exclusive timelines enabling the time points at which the parameter values are fixed to be adjusted without reference to other parameters governing the same video effect.
