Aspect ratio denotes the relationship between the width and height of a video image. 4:3 (1.33:1) and 16:9 (1.77:1) are the two most commonly used aspect ratios today. The main difference between the two aspect ratios is the way they record frames. 4:3 records a frame 33% wider than its height, while 16:9 is 78% wider than it is tall, making the picture feel more immersive and larger. Many old movies and traditional TVs use the 4:3 aspect ratio, also known as the fullscreen ratio. But with the growing popularity of HD TVs, 16:9 became the standard format for modern widescreen TVs and films.
However, since most old videos come with a 4:3 aspect ratio, you may often need to play a 4:3 video on a 16:9 display. Then, you'd probably notice the blank areas on the sides are filled in. It is called pillarboxing. In some other conditions, the video can also be stretched to fit screen. To avoid such effects, you should convert 4:3 to 16:9 first. In the next part, we will introduce a simple video aspect ratio converter to help you change video aspect ratio from 4:3 to 16:9. Read on for more details.
