Change Aspect Ratio in iMovie on iPhone / Mac

This article focuses on changing the iMovie aspect ratio on iPhone or Mac.

In simplest terms, the term “Aspect Ratio” defines the ratio between the width and height of a given video. That is exactly how a given video appears on your screen.

That said, this article specifically discusses iMovie aspect ratio change.

Why Do We Need to Change iMovie Aspect Ratio on iPhone?

As mentioned earlier, the aspect ratio is between the video’s width and height. The aspect ratio of that video is set by the device that captures the original footage. For instance, your digital camera, laptop, computer, or phone have their aspect ratio values.

As of today, it is 16:9, regarded as a standard or commonly accepted aspect ratio. The same aspect ratio is considered the “Widescreen Aspect Ratio.” This is the preferred aspect ratio for TV, computers, smartphones, etc.

You can find other commonly used aspect ratios as well. 4:3 is one of those aspect ratios found in older screens (which are nearly squares). On the other hand, 1:1 is used for Instagram, and 9:16 is for TikTok. Meanwhile, 21:9 is used on cinema screens.

Sometimes, you should upload an image or a video to some platforms with specific ratios. For instance, the videos uploaded to YouTube should be 16:9. Also, some platforms crop your videos abnormally. If not, those videos may get stretched if you don’t use the required aspect ratio.

If you apply the appropriate aspect ratio, you can avoid all those unpleasant conditions. So, if you have shot a video using your iPhone, you should change it based on the platform. That is exactly why every iPhone user should learn about the iMovie change aspect ratio.
