How to Blur Background in CapCut (Full Step-by-Step Guide)

Blurring the background in videos makes your subject stand out and gives a professional look. CapCut, a popular video editing app, lets you blur backgrounds easily without needing a computer. You can use it to create cinematic, aesthetic, or portrait-style videos for TikTok, Instagram, or YouTube. This article explains all methods to blur backgrounds in CapCut and how to get the best results.

Understanding Background Blur in CapCut
Background blur is a visual effect that softens or hides the background while keeping the main subject in focus. CapCut offers both automatic and manual blur tools. You can use the built-in “Auto Background Blur,” add a “Blur Effect,” or apply blur using overlays and masking. These tools help whether you are editing a portrait video, a vlog, or a product video.

Method 1: Use the Auto Background Blur Feature
CapCut includes an AI-powered background blur tool that detects and separates your subject automatically. This is the easiest method.

1. Open CapCut and create a new project.
2. Import your video clip.
3. Tap on the video layer in the timeline.
4. Scroll through the bottom menu and select “Remove Background.”
5. Wait for the app to process. Once the background is removed, tap “Effects.”
6. Choose “Video Effects” and select “Basic Blur.”
7. Apply the blur effect to the layer behind your main subject.
8. Adjust the blur intensity using the slider.

This method works best when your subject is clearly visible and the background has a strong contrast.

Method 2: Add a Blur Effect to the Entire Video
If you want to blur everything equally or create a dreamy atmosphere:

1. Open your project and import your video.
2. Tap “Effects” at the bottom.
3. Choose “Video Effects” → “Basic.”
4. Scroll down and select “Blur.”
5. Adjust the strength and duration of the blur using the sliders.

This method blurs the whole video rather than isolating the subject. It’s perfect for transitions or aesthetic background videos.

Method 3: Use an Overlay and Mask for Background Blur
If you want to blur only certain parts, like the sides or background behind a subject:

1. Open CapCut and import your main video.
2. Tap “Overlay” and add the same video again as an overlay.
3. Select the overlay clip and go to “Effects.”
4. Apply the “Blur” effect to this overlay.
5. Use the “Mask” tool to shape the blur.
   • Choose “Rectangle” or “Circle” for the area you want to blur.
   • Invert the mask to blur everything except your subject.
6. Adjust the feather and opacity for smooth blending.

This technique gives you full control over where the blur appears. It’s more advanced but gives professional results.

Method 4: Add Motion Blur for Moving Backgrounds
CapCut also offers a “Motion Blur” effect for dynamic scenes. This creates a smooth cinematic movement.

1. Tap on your video in the timeline.
2. Scroll and select “Motion Blur.”
3. Adjust the blur level and blend settings.
4. Play the video to preview the effect.

This option works best for sports clips, travel videos, or action scenes.

Method 5: Blur Background of Photos in CapCut
You can also blur the background of still photos in CapCut.

1. Import the photo.
2. Add it as a layer twice.
3. Apply a “Blur Effect” to the bottom layer.
4. Use the “Mask” tool on the top layer to reveal only the subject area.
5. Adjust the blur level and feather for a clean portrait look.

This is perfect for thumbnails, profile videos, or aesthetic edits.

Tips to Get the Best Results

• Always use high-quality footage. Low-resolution clips make the blur look rough.
• Keep your subject centered to help AI detect them correctly.
• If the app removes parts of the subject by mistake, adjust the mask manually.
• Use subtle blur intensity. Too much blur can look unnatural.
• Combine background blur with color grading to make your videos more cinematic.
• Preview your edits before exporting to ensure the transitions are smooth.

Fixing Common Problems
Sometimes CapCut may not detect the subject perfectly or leave edges unblurred. To fix this:

• Use a contrasting background when recording your video.
• Try the manual mask method for better control.
• Update CapCut to the latest version for improved AI performance.
  If your phone lags during editing, close other apps and reduce video resolution.

Exporting the Final Video
After adding the blur, export the video in high quality.

1. Tap the export icon in the top right corner.
2. Choose 1080p or 4K for sharpness.
3. Set frame rate to 30 fps or 60 fps depending on your content.
4. Save and share your video directly to TikTok, Instagram, or YouTube.
