A video composition apparatus and method select segments from image source material stored on at least one storage media and denote serially connected sequences of the segments to thereby form a composition sequence. The apparatus and method employ pictorial labels associated with each segment for ease of manipulating the segments to form the composition sequence. The labels are displayed on an ordered spatial array of display monitors to simulate the temporal relationship between the segments in what is typically a "snapshot" non-temporal display. The composition control function is highly user interactive and responds to user commands for selectively displaying segments from the source material on a pictorial display. The control function allows the user to denote a start and end of each of a plurality of selected segments to form defined segments, identify each selected segment by a pictorial image segment label which is displayed as described above, and assemble the selected and defined segments, and the corresponding labels, into a serially connected image sequence and a serially connected label sequence corresponding to the image sequence. The composition mode of operation employs continuous looping of the displayed segment(s) to aid in the composing process.
