Replace the background in CapCut

The short answer

In CapCut for PC, "changing the background" can mean two different jobs, and they use different tools. If your clip doesn't fill the frame, you change the canvas behind it to a solid color, a blur or an image. If you want to swap out what is behind a person in webcam or camera footage, you remove the original background from the clip and then place a new image or video on a track beneath it. Both are video edits only. Neither changes the recorded audio.

No version-specific documentation was available for this guide. The control names below describe how CapCut's desktop editor is generally organized, but labels and their locations change between releases. Check them against the version you have installed. This guide also does not cover which features require a paid plan.

Option 1: Change the canvas background (color, blur or image)

Use this when a vertical clip sits inside a horizontal project, or when a clip is scaled down and leaves empty space around it. The canvas is the area behind the clip, not anything inside the footage.

• 1. Import your video and drag it onto the timeline.
• 2. Select the clip on the timeline so its properties appear in the panel on the right.
• 3. In the Video properties, find the background or canvas setting. Depending on the version, it may be under Basic or have its own Background section.
• 4. Choose a solid color, a blur of the clip itself, or an image you upload as the fill.
• 5. If the project has several clips, look for an option to apply the background to all of them. Otherwise, repeat the steps for each clip.
• 6. Play the preview and confirm the new fill shows wherever the clip doesn't cover the frame.

If the clip already fills the whole frame, the canvas setting has no visible effect. In that case you need Option 2.

Option 2: Replace the background behind a person

This is the method for talking-head or webcam recordings where you want the person kept and the room replaced. CapCut's desktop editor offers background removal on video clips. It typically includes an automatic mode that detects the person, a chroma key mode for footage shot against a green or other evenly colored backdrop, and in some versions a custom mode where you mark the area to keep.

• 1. Put your new background image or video on the main timeline track and stretch it to match the length of your footage.
• 2. Add your person footage on a track above it, as an overlay, so it sits on top.
• 3. Select the person clip and open the background removal control in its Video properties. In many versions it is labeled Remove BG or Cutout.
• 4. Choose automatic removal for ordinary footage. Choose chroma key if you filmed against a solid-color screen, then pick that color and adjust the strength until it disappears cleanly.
• 5. Resize and position the person clip so it sits naturally against the new background.
• 6. Scrub through the whole clip. Watch for flickering edges, hair or hands disappearing, and leftover patches of the old background, especially during fast movement.

Automatic removal relies on the software telling the subject apart from the scene. As a general principle, it does better with good lighting and clear contrast between the person and the room. A properly lit, evenly colored backdrop usually gives chroma key cleaner edges than automatic detection. How well either works on your footage is something you can only judge by checking the preview.

What background replacement means for your speech audio

Removing or replacing the background only affects the picture. The speech captured by your webcam or external microphone stays exactly as it was recorded. Room echo, fan hum and keyboard noise remain even when the room is no longer visible. That mismatch can be noticeable: a clean studio-style backdrop paired with a reverberant, noisy voice track looks and sounds inconsistent.

• Keep the audio on the clip you keep. In Option 2 the voice belongs to the person footage. If your background is a video with its own sound, mute that track so it doesn't compete with the speech.
• Treat noise separately. CapCut includes audio noise reduction in its audio properties. It works independently of the background tools, so it won't affect the picture. Labels vary by version.
• Check sync after editing. Trimming or moving the overlay clip moves its audio with it. Play the finished section and confirm lip movement still matches the voice.
• Fix capture issues at the source. If the speech is thin, distant or noisy, editing can only partly repair it. Microphone choice and placement during recording matter more than anything done afterward.

Gaps in this guide

No confirmed evidence was supplied about specific CapCut versions, exact menu paths, export behavior, pricing or feature availability by plan or region. The steps above reflect CapCut's general desktop workflow rather than a verified walkthrough of a specific release. If a control isn't where you expect it, look in the selected clip's Video properties first, since that is where background and cutout settings are usually grouped.
