Video Background Changer

Change the background of a video to any picture or color. The AI separates the person from the scene, so you do not need a green screen, and the video never leaves your device.

How to change a video background

  1. Drop your video. Any MP4, MOV, WebM or MKV clip with a person in it. The preview shows the AI cutout on one frame.
  2. Pick the new background. Image is already selected; click Choose image and select a JPG, PNG or WebP. For a plain backdrop, click Color and pick any color.
  3. Check a few frames. Drag the slider to moments with fast movement or hands near the edge of the body.
  4. Refine the edges. Shrink / expand trims or grows the outline; Feather softens it so the person blends into the new scene.
  5. Export as MP4. Choose 720p, 1080p or the original size and click Export video. The audio is kept.

What the video background changer can do

Choosing a background that looks real

The cutout can be perfect and the result can still look fake if the background does not match the footage. A few checks help a lot:

CheckWhy it mattersWhat to do
Light directionShadows on the face should agree with the scenePick an image lit from the same side as your subject
Camera heightA floor seen from above behind a person filmed at eye level looks wrongUse a background photographed at the same height
SharpnessReal cameras blur the background behind a sharp subjectUse a softer image or add a little blur to it before uploading
Color temperatureA warm face on a cold blue scene stands outPick images with a similar warmth to your footage
Aspect ratioA square image on 16:9 video gets croppedUse an image with the same shape as the video

AI cutout for people, color key for screens

This video background changer uses AI by default because most clips are not shot on a green screen. The AI is trained to find people, including hair, and it carries information from frame to frame, so the outline stays steady instead of flickering.

If your clip was filmed on a green or blue screen, switch Method to Color key: it is faster and exact on a good screen. The chroma key page explains the settings.

Where people use a changed video background

Speed and privacy

The AI runs on your graphics card through WebGPU in Chrome and Edge, and on the processor in other browsers. A GPU is many times faster; on a CPU, export at 720p and keep clips short. In both cases the file is processed locally. Nothing is uploaded, so there is no upload time, no queue and nobody else sees your video.

For the full list of options, including transparent export, use the main video background remover.

Video background changer FAQ

Can I change a video background without a green screen?

Yes. The video background changer uses AI cutout by default, which finds people in normal footage. You do not need a green screen or any special setup.

What kind of background image works best?

Use an image at least as large as your video, ideally with the same aspect ratio, for example 1920 by 1080 for landscape video. The image is scaled to fill the frame, so the edges of a differently shaped picture are cropped.

Can I use a video as the new background?

Not yet. You can use an image, a solid color or a blurred version of the original background. To combine with a background video, export a transparent WebM or a green screen MP4 and layer it in your editor.

Will it work with more than one person?

Yes, the AI keeps everyone it recognizes as a person. People far in the background may be partly kept; use Shrink / expand to tighten the cutout.

Does the video background changer add a watermark?

No. There is no watermark, no sign-up and no limit on how many videos you change.

Why does the first run take longer?

The first time, your browser downloads the AI model, about 15 MB, and stores it. After that it loads from your device and starts much faster.
