MATLAB: What Does 20/400 Mean

From the doc: "Location of bottom left corner of video window, specified as the comma-separated pair consisting of 'Location' and a two-element vector. The first and second elements are specified in pixels and represent the horizontal and vertical coordinates respectively. The coordinates [0 0] represent the bottom left corner of the screen. The default location depends on the screen resolution, and will result in a window positioned in the center of the screen."

So [20,40] corresponds to the bottom left hand corner of the Video Player in terms of pixels on the monitor.
