Understanding the Aspect Ratio in iMovie

The aspect ratio of a video refers to the proportional relationship between its width and height. It determines the shape and dimensions of the video frame, impacting how it appears on different screens and platforms. In iMovie, Apple’s popular video editing software, understanding and managing the aspect ratio is crucial for achieving the desired visual presentation. This article aims to provide an in-depth understanding of the aspect ratio in iMovie and the methods to change it effectively.

By default, iMovie uses an aspect ratio of 16:9, also known as widescreen format. This aspect ratio is commonly used for modern televisions, computer monitors, and online video platforms. It provides a wide and cinematic viewing experience, suitable for various video content, including movies, documentaries, and YouTube videos.
