Shot for chroma keying? Upload the video and RemoveVideoBG's AI cuts out the subject without asking you for a key color. Save the cutout as a transparent WebM, or as an MP4 or MOV on a solid color.
Before / after
The subject stays and the backdrop goes: that is what a chroma key remover does. Drag the slider on each sample, from a webcam recording to an animated character, to compare the original footage with the result before you try your own clip.

Workflow benefits
A chroma key remover turns one take into four useful results: a transparent layer, a cutout from the subject, a finished backdrop and a clip that keeps its voice, all from a single upload.
Upload a take shot against a chroma key backdrop and the chroma key remover hands back the subject as a transparent WebM with a true alpha channel. The layer stays separate from whatever sits behind it, so a lesson, a web page or a title sequence can swap its scenery without keying the take a second time.
Create a Transparent Clip
A color keyer removes whatever matches the color you pick. This chroma key remover works from the subject itself: the AI finds the person, product or character and leaves the rest of the frame behind, and you judge the result in the preview before you download it. It takes the place of the keying step for footage you have already recorded.
Use Your Own FootageWhen the next step needs a ready background instead of a layer, the chroma key remover can place the subject on one of nine preset colors or on a picture you upload. The result is a finished clip, so it suits a lesson, a title card or a product page without a second compositing pass.
Cut Out Your Brand VideoA reaction, a lesson or a facecam works best with its voice. Choose a preset solid color and the MP4 or MOV you download carries your original audio along with the cutout, ready for captions and cutaways in your editor. A picture background gives an MP4 with the image alone, ready for a soundtrack of your own.
Start With One ClipStep by step
Using a chroma key remover online takes three steps: upload your clip, choose a background and download the result. Each step below takes a recording from your device to a cutout that is ready for your next edit.
Drag in the recording you shot for keying; MP4, MOV and WebM video up to 100 MB all work, and a sample clip is there if you want to look around first. Since the chroma key remover reads the subject rather than a backdrop color, there is no key color to set up before you continue.
Set Background to Transparent for a WebM layer, Solid color for an MP4 or MOV, or Background image for an MP4. The credit quote appears before you confirm, and the cloud queue behind the chroma key remover handles the rest while you wait.
Play the WebM or MP4 preview and look closely at hair, hands and fast motion. For a transparent result, switch the preview backdrop between checkerboard, dark and light to judge the outline, then download the file that suits your edit.
Project ideas
A chroma key remover helps wherever footage filmed against a chroma key backdrop needs a new scene. These four examples show where the result goes once the backdrop is gone, from a gameplay edit to a product page.
Record a facecam against your chroma key backdrop and run it through the chroma key remover once. The transparent WebM then layers over a recorded match, short clip or channel trailer, so your face stays on its own layer while the gameplay changes underneath.
Film a reaction or commentary take once, then lift yourself off the backdrop with the chroma key remover. Put the layer beside the clip you are discussing and add captions and cutaways, so one recording can carry a whole episode.
Take a presenter recorded for a virtual studio and place the transparent WebM over your studio artwork for a course module or a channel segment. Add lower thirds and a soundtrack in your editor once the layer is in place.
Shoot hands and products against a plain chroma key backdrop, then use the chroma key remover to prepare each demonstration as a transparent layer. Set the product over campaign artwork, a brand color or a shop banner, and reuse the same take across every version of the ad.
Creator stories & examples
“My yoga-studio client records each class in front of a plain wall, and my old keyer kept eating the fringe of her scarf. I ran a take through the chroma key remover and downloaded the transparent WebM. Over the sunrise graphic her scarf kept its soft edge, and the class page finally looked as calm as the class.”
Questions and answers
A chroma key remover takes the backdrop out of a recorded video; these answers cover the files you get back, what you can upload and how to check the result.
A chroma key remover takes the plain backdrop out of footage filmed for chromakey, so the subject can enter a new scene. RemoveVideoBG's version works on video with AI: you upload an MP4, MOV or WebM clip, not a still picture, and get the subject back as a transparent WebM.
No — this chroma key remover relies on AI to find the subject in the scene, which leaves no key color to select. A color keyer removes every pixel near its key color, which can cut into a subject wearing that shade; here the preview lets you check the result before anything is downloaded.
In RemoveVideoBG the chroma key remover and the green screen remover are two names for the same tool. Both use AI to cut a subject out of recorded video and offer the same outputs, so start here if you think in chroma key green screen terms, or on the green screen remover page if your footage was shot against green.
Yes — upload your recording and the chroma key remover separates the subject from whatever is behind it. The backdrop need not be a keying color, and for footage with no chroma key backdrop at all, the video background remover on the RemoveVideoBG home page is the dedicated starting point.
A WebM with a VP9 alpha channel keeps the transparency, and the chroma key remover exports one when you choose Transparent. Open it in an editor that reads WebM transparency, or place it on a web page. MP4 and ProRes MOV exports come with a solid color behind the subject, and the MP4 built on a picture you upload shows that picture instead, so both are finished clips rather than layers.
Yes — a solid-color export in MP4 or MOV keeps your original audio. A voice recorded with the footage reaches your editor along with the picture, while the MP4 you build on a background image carries the picture alone, ready for a soundtrack you add yourself.
RemoveVideoBG's chroma key remover takes MP4, MOV and WebM files up to 100 MB. A single run covers up to 60 seconds of video at up to 4K resolution; for a longer recording, select the 60-second stretch you need on the trim timeline.
Yes — this chroma key remover uploads your clip to RemoveVideoBG's cloud storage, where an AI service processes it. You only need a browser to preview and download the result, with nothing to install.
Yes — you can try chroma key online with free credits in this chroma key remover, and its exports carry no watermark. New accounts receive free credits and a daily login reward adds more; you see the credit quote for your clip before anything is processed, so you know the cost before you commit.
Play the whole WebM or MP4 preview and pause wherever the subject moves quickly or crosses a busy part of the scene. Compare how the edge looks from frame to frame: a steady edge means the chroma key remover has done its job and the clip is ready to download. A ProRes MOV plays in your editor or media player once downloaded.
