Abstract In a digital computer system running a windows operating system and a video editor where the video data is stored in the memory and clips of the video data consisting of sequences of video frames are represented by blocks in a workspace on the video display. A video cursor is provided to scroll through the frames. The disclosure describes a convenient method of allowing the user to control the scale of the horizontal axis and thus the number of video frames that may be symbolically viewed on the workspace window without panning. The method includes the following steps: First, determining if the video cursor is being intentionally moved vertically by a user. Next, determine the vertical distance that the video cursor is moved from a reference point. Finally, adjust the number of video frames that may be represented on the workspace in relationship to the vertical movement of the video cursor.
In a computer system having a CPU, memory and a video display and wherein video data is stored in said memory and wherein clips of said video data consisting of sequences of video frames are represented by blocks in a workspace on said video display, and wherein a video cursor is provided to scroll through said frames, the method including the following steps: determining if said video cursor is being intentionally moved vertically by a user; determining the vertical distance that said video cursor is moved from a reference point; and adjusting the scale of the horizontal axis of said workspace in relationship to the vertical movement of said video cursor so that the number of video frames that may be represented on said workspace varies accordingly.
