Part 1: How to Blur A Part of Video with iMovie

iMovie doesn't come with a blurring tool or blur effect to conceal someone's face or an object in your video. Below are two ideas you could use to suit your needs.

1. Capture Screenshot and Blur Image with Photo Editor

First make a screenshot of the scenes where you want to do a blur effect using SHIFT+COMMAND+4. Then open Photoshop, GIMP, Pixelmator or other photo editor to blur anything you want on the video. Finally, import the screenshot to iMovie and make it as a picture-in-picture layer so you can movie and resize it to get a good look.

2. Using a photo clip to hide faces in iMovie

Simply, you can import a small image like a sticker or a lovely carton character, and drag above the video in which you want to hide a face. Drag more photo clips if you have multiple face to block out. Change the layer to picture-in-picture to you can resize it and put it anywhere you want in your video.
