How To Replace A Background Using AI in CapCut!

Introduction

Replacing your video background can elevate your content, but what if you don’t have access to a physical green screen? Don’t worry! In this guide, I’ll demonstrate how to replace your video background for free using CapCut, while ensuring it looks realistic.

Preparing Your Video

When filming, aim for some separation between your body and the background. For instance, if you're in front of a dark background while wearing a black shirt, lighting is key. Utilizing a light source behind you helps to create a defined outline, making it easier for CapCut to remove the background effectively.

Removing the Background in CapCut

Open CapCut: Launch the desktop editor and upload your clips.
Select Your Clip: Start by selecting the video clip from which you want to remove the background.
Auto Cutout: Navigate to the "Video" section, then find "Cutout" at the bottom. Enable "Auto Cutout," and watch CapCut efficiently remove the background.

It's important to note: If you're editing lengthy footage, trim your clips first to expedite the background removal process.

Generating AI Backgrounds

Instead of searching for free images that may be copyrighted, you can utilize CapCut’s built-in AI generator to create your custom background:

Select AI Generated: On the left sidebar of CapCut, choose "AI Generated."
Describe Your Background: You should provide a brief description of what you want. For example, "photography studio with soft boxes and moody lighting."
Set the Aspect Ratio: Ensure the aspect ratio matches your video (for example, 16:9).
Adjust Steps: By default, this is set to 30; I recommend increasing it to 50 for better quality.
Click Generate: CapCut will generate images based on your description. Once generated, choose one you like and click "HD" to download a high-resolution version.

Layering Your Clips

Insert Background: Import the AI-generated image into your project. Make sure to position it behind your talking clip.
Resize and Position: Adjust the size of the background and position it correctly.
Shorten Clip: Ensure your talking clip matches the length of the background image.
Color Correction: To create a more natural look, use CapCut’s "Adjustment" option to alter the brightness of the background. Often, the background should be darker than the foreground.

Adding Blur and Depth

Apply Blur Effect: To simulate a shallow depth of field, search for the “Blur” effect and apply it to the background layer.
Rearrange Layers: If the blur affects your main subject, ensure you layer your talking clip above the blurred background.
Finalize Adjustments: Tweak the blur intensity and any other color adjustments to ensure a seamless integration of your foreground with the background.

Advanced Techniques

For a more sophisticated effect, consider using the Relight feature (available in CapCut Pro) to add virtual lighting that matches your background source. This can significantly enhance realism, but it's optional.

Conclusion

By following these steps—utilizing auto cutouts, generating AI backgrounds, and making color adjustments—you can create professional and eye-catching videos without needing physical green screens. Experiment with this process to curate backgrounds that fit your video's needs perfectly.
