Use AI Video Background Remover to isolate a subject from ordinary footage today.
This video green screen remover gives you live feedback, focused chroma key controls, and transparent output without uploading the source video to a processing server.
See the chroma key result as you adjust settings. Each change updates in your browser without waiting for a server render.
Sample a background color directly from a frame, then tune similarity, edge softness, and spill suppression for a cleaner key.
Export transparent VP9 WebM with audio when supported, or a PNG Sequence ZIP with timing metadata and no audio.
Your source footage is processed on this device and is not uploaded by this tool. No account or credits are required.
Three simple steps
Import one green screen video, refine the key with live feedback, then export a transparent result your browser can create.
Choose one MP4, MOV, M4V, or WebM file. The tool checks the container, codec, and local browser capabilities before enabling output.
Sample the screen color, adjust similarity, edge softness, and spill suppression, then compare Original, Result, and Alpha Matte.
Choose original size, fit within 1080p, or fit within 720p, then export transparent WebM or a PNG Sequence ZIP when supported.
Green screen removal, also called chroma keying, makes pixels close to a selected background color transparent. This lets you composite the subject over another video, image, color, or interface later.
Unlike AI background removal, chroma keying works best with footage recorded against an evenly lit green or other solid-color screen. It gives you direct control over the color range and edges, but it does not identify a subject in an ordinary complex scene.
A focused local workflow for green screen footage that was recorded against a solid-color background.
Manual key color and similarity settings make the result repeatable when the screen is reasonably even.
Import, preview, adjust, and export without signing in or creating a cloud processing task.
Check Original, Result, and Alpha Matte views over checkerboard, black, or white before export.
The tool checks decoding, graphics, encoding, audio, and saving support and only enables output paths available in your browser.
Give each control one job, then review still and moving frames in Result and Alpha Matte views before export.
Sample a representative midtone from the screen in the current frame.
Watch for
Avoid a bright hotspot, deep shadow, or any part of the subject, and pick again if the screen color changes.
Raise Similarity gradually to include a wider color range around the key.
Watch for
If Similarity is too high, clothing, reflections, or subject detail near that color can become transparent.
Feather the alpha matte transition to reduce a hard cutout edge.
Watch for
Too much Edge Softness can create a halo or wash away hair and motion detail.
Increase Spill Suppression gradually to reduce green contamination near partly transparent hair, skin, or clothing edges.
Watch for
Too much can shift edge color, and it cannot restore detail missing from the source.
Start with small changes and inspect the full clip. Some source problems need better lighting, different wardrobe or props, or a new recording.
Try this
Sample a representative screen color again, then raise Similarity a little at a time while checking the whole frame.
Source limitation
Strong shadows, wrinkles, or hotspots may require more even screen lighting or a new recording.
Try this
Lower Similarity and sample the screen again. Check clothing, props, and reflections near the key color.
Source limitation
A true color conflict may require different materials or another recording.
Try this
Add a small amount of Edge Softness and inspect hair, fingers, and motion blur in Result and Alpha Matte views.
Source limitation
Heavy compression, sharpening, or severe motion blur can limit recoverable edge detail.
Try this
Increase Spill Suppression gradually and compare the result over checkerboard, black, and white.
Source limitation
Strong green bounce may require more distance between subject and screen or different lighting.
Choose the transparent format that matches your next workflow and the capabilities available in this browser.
Export one transparent source, then finish the project in the editor, presentation, or web composition that adds the background and other layers.
Place a keyed presenter over a branded scene in a compatible editor, presentation, or web composition.
Combine a transparent presenter with product footage, screen recordings, or interface visuals in your downstream workflow.
Reuse instructor footage in lesson videos, presentations, and training layouts after export.
Use the same transparent source to create different backgrounds, sizes, or language versions in your downstream editor.
Choose a green screen video and refine the result locally. Your source footage is not uploaded by this tool.
