To hide someone's faces or private information in a video, you may need to blur out part of a video, for example, blurring faces, an object or background in a video.

It is easy to blur faces or objects in a photo, but what about a video? In this article, you'll learn 2 simple ways to blur face, object or background in a video on Windows, Mac, iPhone, Android.

# Method 1: How to Blur Faces in iMovie

If you need to blur faces in a video on iPhone or Mac computer, you can use Apple's iMovie to do that. Although iMovie doesn't have a blur effect, here is a workaround: add a background overlay on the video and use the Picture in Picture feature to adjust the background to cover a face or object.

Step 1: Launch iMovie and import the video with someone's face or an object you want to blur out.

Step 2: Locate the frames with the faces or objects you want to cover in the timeline.

Step 3: Click Backgrounds and add a background above the frames you want to blur. Here we add a black background. Adjust the length of the background to cover all the needed frames.

  • Select a border and tick Shadow.

Step 5: Now adjust the size and position of the black background to fit the face/object that you want to blur.
