![]() If the viewing aspect ratio, the DAR, matches the SAR, then the process of the displaying the stored video is simply a matter of proportionally scaling it to the correct size. When digital video is stored into a file or on a disc, it is stored with a particular frame size and aspect ratio, the SAR. We will try to clarify here how these three aspect ratios work and what role they play in digital video.Īnamorphic video and square vs. ![]() There are, however, two other kinds of aspect ratio that play an important role in digital video: the Pixel Aspect Ratio (PAR), and the aspect ratio of the stored data which we will call the Storage Aspect Ratio (SAR). Typically, this ratio is 16:9 (widescreen) or 4:3 (full screen). This is the ratio of the width to the height of the display frame for the video, the aspect ratio of what we see. The kind of aspect ratio most people know is the Display Aspect Ratio (DAR). The role of aspect ratio in digital video has caused quite a bit of confusion, partly because there are actually three types of aspect ratio, not just one.
