How To Blur in Capcut (Background, Faces, Objects)

This tutorial explains how to blur in Capcut using the software’s basic editing tools.

Adding a blur effect to videos has various applications, from blurring the video background to hiding sensitive information.

I’ve broken down the different ways you can use the blur tool to edit your original video in just a few clicks.

When To Implement the Blur Effect in Video Editing

Applying the blur effect to a video has many applications and is a core skill for any editor working with video content.

It’s one of many great video effects available in the Capcut app, which delivers a flexible approach to adding blur to an edited video.

The effect is widely used to blur video background, creating a bokeh-like aesthetic to your final video before uploading it online.

It can also be used to easily blur faces, for example, when shooting documentary footage that features people in the shot who haven’t signed an NDA.

Likewise, the blur effect can be used to disguise confidential or private information, including vehicle registration plates and classified documents.

Thanks to Capcut’s many blur settings, it can also introduce motion blur and other visually appealing effects.

Let’s dive into the various ways to introduce the blur effect in Capcut while editing videos, from background blurring to other handy blurring techniques.

How To Blur Videos in Capcut – a Complete Guide

There are many ways to utilize the blur effect while editing your videos, and Capcut’s intuitive interface makes the process simple to achieve great results.

You can also combine the blur effect with other Capcut video effects, as well as use it when working with green screen video footage.

Let’s begin with the easiest way to use this versatile feature to create a fully blurred video in just a few clicks.

How To Blur the Entire Video in Capcut

Adding blur to video in Capcut is easy, with basic parameters available to alter the blur intensity.

Blurring an entire video is a common technique used in documentary filmmaking, allowing for captions and other text to be displayed prominently on screen.

Follow these simple steps to apply the blur effect to a full video in Capcut:

1. Open Capcut on your smartphone or with the desktop version and create a New Project.
2. Select the video clip you wish to apply the blur effect to, then tap Add to bring this into your project.
3. Head to the toolbar at the bottom of the user interface and tap on Effects, followed by Video Effects.
4. In the Video Effects menu, scroll to the Lens subcategory to locate and activate the Blur effect.
5. Tap on the icon to make additional adjustments to the effect, altering the blur intensity to achieve the desired results.
6. If you need to adjust the duration of the blur effect to match your uploaded video, you can extend or shorten it in the Capcut video project timeline.

How To Blur Video Backgrounds

If you want to blur a video background, Capcut’s tools allow you to do this in a few simple steps.

While blurring an entire video has limited real-world applications, the blur video background feature is commonly used in content creation.

YouTube content creators and podcasters frequently blur a video background to hide their location or place greater emphasis on their verbal presentations.

Here’s how to use Capcut to introduce a blurred background in your next video:

1. Create a New Project in Capcut, then follow the instructions outlined above to create a fully blurred video.
2. Export this blurred video, then add the original video clip back into your Capcut project as an overlay, removing the blurred version and the blur effect from your project’s timeline.
3. To create the blurred video background, import the blurred version as a media file and drag it onto the timeline beneath your original unblurred clip.
4. Tap on the original version in the timeline, then select Auto Cutout from the Cutout menu.
5. You can refine the accuracy of the cutout by choosing one of the many Stroke options available, or manually adjust the size and opacity to ensure an accurate cutout of your subject.
6. Once you’re happy with the background blur effect, you’re ready to export the video in Capcut to share on your social media channels.

Adding the Blur Effect to a Portion of a Video in Capcut

In addition to the blur background effect, Capcut can be used for face blurring with the blur mask feature.

If you’re looking for a more precise method for blurring video in Capcut, such as applying the effect to faces and objects, you can use the mask tool to fine-tune the blurred area.

Capcut includes powerful editing tools that work in tandem with the blur effects on an original video, catering to many user situations.

Follow these steps to blur faces and other specific objects using the Capcut app:

1. As with the process used to blur a video’s background, blurring specific portions of a clip requires creating a fully blurred copy and placing this with the original video on your project timeline.
2. Once this has been done, instead of using the Cutout tool, head to the Mask tool options, choosing the mask shape that best matches the face or object you wish to blur.
3. In the player preview window, adjust the mask using the transform tool until it matches the on-screen subject or object.
4. Make any additional alternations with the feather slider to finalize your mask.
5. Tap on the tick mark at the bottom of the interface to complete the process and your blurred video is ready to export.

Tracking Subjects and Objects With the Blur Effect

Adding keyframes to video in Capcut allows you to track around the screen and ensure the blur remains in the correct position.

Since camera and subject motion can easily affect the position of your blur effect, sometimes you’ll need to use keyframes to ensure the relevant areas remain out of focus.

This is where Capcut’s handy keyframes feature comes into play, allowing you to reposition and reshape your blur mask at any point in the video.

To do this, you’ll need to follow the first four steps outlined above in the step-by-step guide to blurring a portion of the video.

Once you’ve created your initial mask to apply the blur, follow these additional steps:

1. Play through the video until you reach the first point where the mask blur no longer matches the position of the subject.
2. Pause the video at this point, then tap on the diamond icon at the top of the screen to add your first keyframe to your project.
3. With the keyframe selected, head to the Mask option and reposition and reshape your blur mask so it matches the current position of the subject or object.
4. Once you’re happy with the position, tap on the tick icon to confirm the new blur mask on the project timeline.
5. Repeat the above steps to alter the mask’s position for any other relevant points in the video clip.
