Final answer:
The aspect ratio refers to the proportion of width to height in a video frame, determining its shape and dimensions.
Step-by-step explanation:
The aspect ratio refers to the proportion of width to height in a video frame. It is commonly expressed as a ratio, such as 16:9 or 4:3.
For example, a 16:9 aspect ratio means that the width is 16 units and the height is 9 units. This ratio determines the shape and dimensions of the video frame.
An aspect ratio of 4:3 is commonly used in older television broadcasts, while a 16:9 ratio is the standard for modern high-definition content. Different aspect ratios can impact how videos and images are displayed on different devices.
