Abstract: A method and system for graphic video image control of selected segments of video data from within a video presentation which includes a large number of video frames. The video frames are displayed in a stacked overlapping manner within a computer display system. Upon selection of a particular edge of the display of an uppermost frame, each frame is then slightly offset from an adjacent frame such that a small portion of each overlapped frame may be visually accessed. A user may then select some portion of the video presentation for display by observing the transition effects along the exposed edge of each frame and then graphically selecting a particular frame utilizing a graphical pointing device, such as a mouse pointer. The selected frame is then displayed and a particular portion of the video presentation, beginning at the selected frame, may then be presented, greatly enhancing the efficiency of video display control.
