Part 1. What is the Aspect Ratio of Video

Before learning how to convert video aspect ratio, it is best to learn about the aspect ratio. In this case, an aspect ratio determines the size of an image or video by providing a ratio of width and height as measured in pixels. Know that this type of measurement is only for the ratio between width and height and not necessarily the number of pixels like a video resolution does.

To give an example, an aspect ratio of 16:9 means 16 units in width and 9 units in height. A video resolution will counterpart 16:9 with a 1920px by 1080px, as the number of pixels displayed.
