Add a New Background to Video Online

A technically clean cutout can still look artificial when the new scene has a different camera angle or lighting direction. Choose backgrounds with enough empty space around the subject.

For vertical social clips, begin with a vertical background instead of relying on a wide image that must be heavily cropped.

The replacement file can be JPG, PNG, or WebP. Dynamic background video is not part of the current product workflow.

Automatic matting follows the visible foreground instead of asking you to draw a mask on every frame. It is designed for people, products, and other clearly separated subjects in ordinary footage, including clips recorded without a green screen.

The result still depends on the source. Fine hair, motion blur, transparent objects, deep shadows, and temporary occlusion should be checked across the full timeline rather than judged from a single preview frame.

Use the highest-quality original available instead of a copy downloaded from a social platform. Keep the subject large enough to see, avoid aggressive compression, and prefer even lighting with visual separation between foreground and background.

Preview the beginning, middle, and end before upload. A clip that looks easy in its first frame may contain crossed hands, hair movement, camera cuts, fast rotation, or an object that briefly disappears behind another element.

The live remover accepts MP4, MOV, and WebM. Transparent mode returns WebM; custom-background mode accepts one JPG, PNG, or WebP image up to 10 MB. A still image is composited behind the isolated foreground—the product does not currently accept a replacement video.

The free trial supports one verified clip up to 5 seconds and 50 MB. Paid plans raise the limit to 60, 180, or 300 seconds and 200 or 500 MB depending on tier. Processing credits are rounded up in five-second blocks, so a 6-second clip uses 10 credits.
