Man Taking Video With Phone

Whether it’s a party, a fun day with your family and friends, part of your job as a content creator, or anything, you no longer need a DSLR to shoot incredible video clips. Your iPhone camera is more than capable of recording amazing videos. However, you might need to blur some parts that you unintentionally captured, which would otherwise be embarrassing if they appeared in your final video. For that, you should know how to blur a video on iPhone.

Quick Answer

There are two very effective methods to blur a video on iPhone. One is to use the iMovie app’s merger feature to superimpose a blurred picture over your video. The other method involves using Blur Video Background, a third-party video editing app with a blurring feature. 

We’ll discuss these two methods in detail below, and we assure you that you’ll find them easy to use. So, let’s get right into it!

Two Methods to Blur a Video on iPhone

Method #1: Use the iMovie App

Apple’s iMovie app (iMovie HD) is a helpful video editing tool but lacks a built-in blurring feature. So, how can you use it to blur a video if it doesn’t have its own blurring option? 

There’s a possible workaround, and that’s to use its merger option to blur videos. In other words, you’ll superimpose a blurred, black, or pixelated image over your video to achieve the mission. Here are the steps to follow:

Step #1: Choose a Video to Blur

Start by downloading a pixelated, blurred, or black picture, and then open the iMovie app on your iPhone. Click on the Plus (+) button and choose “Movie” to initiate a new project. Alternatively, you can edit an existing project. After that, find and select the video you wish to blur and click on the “Create Movie” option.  

Step #2: Add the Blurred/Pixelated/Black Picture over Your Video

Click on the Plus (+) icon to choose the picture you’ve just downloaded on the editing page. Select your image and click on the three dots icon. Finally, choose the “Picture in Picture” option. 

Step #3: Apply the Blur

After adding the picture to the editing page, edit and drag it to the part of the video that you wish to blur. Make sure that you’ve applied the blur on the video properly – apply for the entire length of your video. 

Step #4: Save Your Video

Play your final video to see if the results are satisfactory. Click on the “Done” option to add the video to your iMovie Projects if everything is okay. You can alternatively click on the “Upload” icon to share the video.


iMovie app may not be installed on your iPhone by default. The app is available for free on the Apple App Store, and you just need to download and install it on your device.

Method #2: Use Blur Video Background App

There are many video editing apps for iPhone with blurring features out there. However, Blur Video Background is one of the best apps for blurring faces or scenes in a video. Below are the steps to use it to blur a video on iPhone. 

Step #1: Download and Install the App

Download the Blur Video Background app and install it on your device. You’ll be ready to start the video editing process once you do that. 

Step #2: Choose a Video to Blur

Choose the video you want to blur from My Videos, Camera, or Gallery. You’ll find a toggle bar on top of the editing page to choose between pixelate and blur.

Choose the Circle or Rectangle option as the shape of your blurring path. You’ll find the options on the taskbar at the bottom of your screen. Now apply the type and shape you’ve chosen to the parts of the video.  

Step #3: Save Your Edited Video

You need to save your video once you finish blurring it – you’ve already done the hard part, so it’s easy to save the video. 

Click on the “Upload” icon on the top-right section of the screen. You’ll need to choose the resolution or size of your video (video quality). You’ve four options – Normal 480P, HD 20P, Full HD 1080P, and 4K. 

Once the video is created to your chosen size, choose the “Save to Camera Roll” option or Share it with friends on Instagram, Facebook, etc. 


The above was our article on How to Blur a Video on iPhone. There are mainly two methods to do so. Method #1: using the iMovie app, and Method #2: using a third-party video editing application with a blurring feature (Blur Video Background).

We’ve learned that the iMovie app doesn’t have a blurring feature. However, it has a useful merge option that allows you to superimpose a blurred, black, or pixelated image over your video to achieve the blurring effect. 

As you might have realized, the steps in each method are simple to follow and execute. We hope that we were able to help you blur the video you wanted on your iPhone.
