How to blur part of a video on iPhone with the iMovie app?

The iMovie is Apple’s native video editing app supported by your iPhone. Though it is a decent video editor tool, it doesn’t have a built-in blurring tool. So if it doesn’t have its own blur option, then why are we writing about this app?


This is because we’ve found a way to use the app’s merger feature to blur videos. The actual censorship of your video on iMovie can be achieved by superimposing a blurred picture over the video. This will create an almost similar blur video effect as that of any blurring app. The ideal size of the photo is expected to be small.

Follow these steps to find out how to blur part of a video on iPhone using the iMovie app:
