Winston has been relegated unceremoniously to off-camera invisibility. And here I must beg your patience for a necessary digression into the nature of video. Film is composed of a series of still images. Twenty-four frames are projected onto the motion picture screen each second. Each frame is a whole unit, a complete image, analogous to a 35mm slide.
Video is quite different.
Each visible image is created by drawing the picture with horizontal stripes called horizontal scan lines. Each scan line has a measurable height and a measurable spacing between scan lines, so each picture is crudely divided into 480 horizontal scan lines with a small black spaces between them. The height of the image remains the same. But due to the aspect ratios of widescreen film formats, the film's image doesn't fill the height of the video frame. Those areas are left black.
