Abstract
A method of animating a sprite in a video production comprising a plurality of sequential video frames is disclosed. The method comprises the steps of selecting (2004) a feature, with which the sprite is to be juxtaposed, in one of said video frames, applying (2006) a feature tracking process to the video production to thereby output (2008), for a series of said plurality of video frames containing the feature, a temporal-spatial record for the feature across the plurality of video frames, and compositing (2010), with the series of said plurality of video frames, a corresponding series of instantiations of the sprite dependent upon the temporal-spatial record.
