An image data editing facility produces a sequence of output image frames. A wipe animation is produced over a sequence of output frames such that an increasing proportion of the output image is derived from a second sequence of frames and a decreasing proportion of the output image is derived from a first sequence of frames, under the control of a moving boundary defined by a wipe animation. The rate of expansion of boundary is controlled with reference to an animation parameter and the animation parameter is derived from processing at least one stored position parameter with reference to a selected animation starting location.

Image data editing

A multitrack architecture for computer-based editing of multimedia sequences is disclosed herein. The multimedia sequences are formed of a plurality of collated segments representing audio or video scenes. The architecture contains sequence tracks for ordering the segments of the multimedia sequence and process tracks for applying transformations and/or animations to some of these segments. The output of the process tracks may be supplied to other process tracks and/or to a sequence track. Scope controls are provided to determine which portion of the output of a process track is supplied to another process track and/or to a sequence track.
