# 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 4: Click on the video overlay settings icon to adjust the background.
Select Picture in Picture;
Set the Dissolve to 0.0s;
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.
Step 6: Click the keyframe icon to enable keyframe animation. Then use the arrow buttons on your keyboard to move the location of the background following the motion of the covered faces or objects to create a motion blur.
