How to Remove the Background from a Video Without a Green Screen

Removing the background from a photo is a one-click job in almost any editor these days. Video is harder: the subject has to be separated from the background in every single frame, hair and moving hands included. That used to mean hanging a green sheet behind you or rotoscoping by hand for hours. On ImageGPT you upload a clip of up to a minute and let the AI do it.

The Remove Video Background tool cuts out whoever is in the shot and drops them onto a new background. The audio stays exactly as it was, and every result also comes as a transparent WebM you can layer over other footage or a slide.

One clip, three backgrounds

The source is a 6-second vertical clip of a woman talking by the river. Both the clip and the woman were generated by AI.

If you edit your own videos, you'll usually want a green screen — a flat chroma-key background that any editor removes in one click. Here's a horizontal clip of a man walking towards the camera (also AI-generated), now walking on green.

What you need

• A clip between 1 and 60 seconds, up to 70 MB, in any common format. Cut longer videos into parts first.
• Good light and contrast. The more the subject stands out from what's behind them, the cleaner the edges — a white shirt against a white wall is the hardest case.
• For your own background, a picture in roughly the right shape. It gets cropped to the frame, so use a vertical image for vertical video.

Step by step

1. Open Remove Video Background under Video and upload your clip.
2. If the subject isn't a person — a product, a pet, an object — switch off “There is a person in the shot”, so the AI cuts out the main object instead of looking for people.
3. Under New background, pick Green screen, Colour, Blur, My picture or Generate.
4. For Colour, choose white, black, light grey, blue, amber, pink or a Custom colour. For My picture, upload it. For Generate, write what you want in “Describe the background”.
5. Check the price under the button and click Remove background. The clip is processed frame by frame.
6. Download the MP4 with its new background, or click Download transparent WebM if you need an alpha channel.

Which background to choose

The transparent WebM comes with every result, whatever mode you choose. Modern browsers and editors that support alpha can use it directly — handy for putting a speaker on top of slides or a web page.

Prompts for an AI background

Generate mode draws the scene with GPT Image 2.5. Describe the place and the light, not the person — they're already cut out. A few that work well behind a talking head:

Pricing

The price depends only on the length of the clip and is shown before you start. An AI-generated background adds a few credits; every other mode costs the same. If processing fails, the credits go back to your balance.
