Abstract
An object shown in a first clip of image frames is composited with frames of a second clip on a frame-by-frame basis. A track of positions are determined over time which specify a relationship between a point on frames from said first clip in relation to corresponding frames in said second clip. The object is overlaid transparently over corresponding frames of second clip and the positions of said track are modified. Thereafter, the images are composited on the basis of the modified track positions.
