Free Online Green Screen Editor
Replace a solid-color backdrop with a PNG or JPEG in the green screen editor. Download a 1280 × 720 MP4 with the foreground video and its recorded sound.
How to replace a background with the green screen editor
- Select the foreground video and a still image for the new background.
- Set the color to remove so it matches the backdrop in your footage.
- Export the 720p video and check the edges of hair and clothing.
How the green screen editor combines two layers
Foreground frame
The green area surrounds the red mug and fills the opening in its handle.
Background image
A striped wall and a tan surface fill the 16:9 frame.
Finished frame
The stripes appear through the handle as well as around the mug. The red body stays in front.
These diagrams use a solid green sample frame and a still background. The finished frame was composited with the same color-key settings as the export. Follow a stripe through the handle to see which layer supplies those pixels. With real footage, check similar gaps between fingers or strands of hair, especially while the subject is moving.
Which screen color should I choose?
A green screen editor needs a distinguishable color behind the subject. This tool starts with bright green, but you can change the color using the selector. A blue backdrop can work if the subject contains little of that blue. Examine the actual recorded color on a broad, evenly lit part of the screen. A green cloth under warm indoor lighting may look quite different from the same cloth photographed beside a window.
The green screen editor compares colors across the foreground clip. If the presenter wears a shirt close to the chosen color, the new background can show through the fabric. The same can happen with green lettering on a product, colored reflections on glasses or fine leaves in a plant. Look at the front of the subject as carefully as you look at the backdrop. A color shared by both is difficult to remove selectively with one setting.
Fit the picture to the 720p export
The replacement is a still PNG or JPEG. It fills a frame measuring 1280 × 720 pixels. Prepare a background with the same 16:9 proportions so circles stay round and people in the background keep their natural shape. A square photograph is stretched to fill the frame. Crop a copy to the intended proportions in an image editor first if you need control over which part of the photograph appears behind your subject.
The green screen editor scales the foreground to fit inside that frame while preserving its proportions. It centers the image and adds padding where the proportions differ. That padding can remain visible in the exported composition. A tall recording therefore behaves differently from a wide recording of the same person. Check the complete output frame before choosing a backdrop with important detail near the sides or along the top.
Work with shadows and fine edges
An unevenly lit backdrop can contain pale green highlights and dark olive shadows. Use Screen color to choose a shade close to the cloth beside the subject, then check the exported copy at both its brightest and darkest patches. The green screen editor uses fixed settings for color similarity and edge blending. The available color selector changes the color being removed. It does not independently increase tolerance in a shadow or refine only one part of a person's outline.
Hair, the rim of a glass and a fast-moving hand often include a mixture of subject and backdrop colors within the same pixel. Notice whether the exported edge has a green rim, a gap or a staircase pattern. A background close in brightness to the edge can make a slight fringe less conspicuous. If recording again is possible, move the subject farther from the screen, light the backdrop evenly and avoid casting a hard shadow on it.
Review the foreground against the finished scene
Judge the result against the background you actually intend to use. A narrow gap between strands of hair can disappear against a plain wall but look obvious against a high-contrast bookshelf. Pause at a frame with fine detail and then watch the same area while the subject moves. Sparkling or flickering along the outline can be easier to spot in motion than in a single frame.
The green screen editor combines the two images into one finished video with sound from the foreground recording when available. Listen across any edit already present in that recording. Inspect places where hands move away from the body or a prop first enters the frame. Keep the source clip and background picture together if you plan to revise the composition. To change a sign or picture on the back wall later, replace the still image and export from the source again.
Green screen editor questions
Can I remove a background without a solid screen?
This green screen editor works by matching color. A busy room with furniture, books and skin tones contains many unrelated colors. Selecting one of them can remove parts of the subject while leaving most of the room. For that recording, use a tool that can separate a person from a complex background.
Can the green screen editor export a transparent video?
The output combines the foreground and selected background picture into an MP4. If you need to place the subject over several scenes later, keep the original foreground recording. You can render separate compositions here using different still images or use an editor that exports transparency.
Does the green screen editor accept a background video?
The background picker accepts a PNG or JPEG still. Choose a single picture with enough room for the subject and any gestures. A sequence with moving scenery or a background video that needs synchronization with the foreground calls for an editor with a second video layer.
Why does a bright green edge remain?
The selected screen color may differ from the light reflected onto hair, skin or clothing. Look at the original near those edges and try a more representative screen color. If changing it begins to remove foreground details, use the original and an editor with spill suppression for more local control.
