How does a virtual green screen work?
The tool runs MediaPipe’s Selfie Segmentation in your browser, removes your real background on every frame, and fills the empty pixels with pure #00FF00. The exported WebM looks exactly like footage shot on a physical green screen — except it works in any room, with any lighting, and can be recorded in a café, a hotel, or your bedroom. When you import the file into your NLE and apply a chroma-key filter, the pure green keys out cleanly, leaving a transparent subject you can composite over anything.

How to make a virtual green screen in 5 steps
- 1
Load your clip or camera
Upload MP4, WebM or MOV, or click "Use Camera" to start your webcam. No upload — everything stays local.
- 2
Green Screen mode is on
The Green Screen preset is pre-selected on this page. The AI removes your real background and fills it with pure #00FF00 (broadcast-standard chroma key green).
- 3
Tighten edges for cleaner keying
In the AI Engine tab, adjust mask threshold and edge feathering. For chroma-key export, tighter edges (1–3px) produce cleaner keys with less green halo.
- 4
Record the composited clip
Hit Record to export WebM with green background baked in. Optional audio from your microphone or the source file.
- 5
Key it out in your editor
Import the WebM into Premiere, After Effects, DaVinci, Final Cut, CapCut or OBS. Apply your chroma-key filter to the pure green layer and you have a transparent subject.
How to key out the green in your editor
| Editor | Keyer | Steps |
|---|---|---|
| Adobe Premiere Pro | Ultra Key | Effect Controls → Ultra Key → pick the green, adjust matte settings for spill suppression |
| Adobe After Effects | Keylight (1.2) | Effect → Keying → Keylight → eyedropper green, adjust Screen Balance and Despill |
| DaVinci Resolve | 3D Keyer / Delta Keyer | Fusion page → Keyer node → pick green → adjust Matte, Clean Black/White |
| Final Cut Pro | Built-in Keyer | Effects → Keying → Keyer → pick green → Refine Edge and Spill Suppression |
| CapCut | Chroma Key | Overlay → Chroma Key → pick green → adjust Intensity & Shadow |
| OBS Studio | Chroma Key filter | Right-click source → Filters → Chroma Key → pick green → adjust Similarity, Smoothness, Spill Reduction |
Because the exported green is pure #00FF00 with no colour noise or lighting variance, the keying process is dramatically easier than with a physical green screen — no spill, no inconsistent lighting, no need for a $200 fabric backdrop. This is especially useful for indie creators, game streamers, virtual YouTubers and educators who want professional compositing on a zero-dollar budget.
Virtual green screen vs physical green screen
| Physical green screen | Virtual (ToolDeck) | What you gain |
|---|---|---|
| Requires a physical green backdrop | AI segments you from any room | Zero equipment cost |
| Needs even studio lighting | Works in mixed and natural light | Film anywhere, any time |
| Green spill contaminates clothing | No spill — mask is colour-independent | Cleaner keys in post |
| Setup takes 15+ minutes per shoot | AI is ready in seconds | Faster creative iteration |
| Storage and portability of the screen | Runs on any laptop or phone browser | Film at client sites, cafés, hotels |
| Expensive fabric + lighting kit | Free browser tool | Zero budget for production gear |
The only thing a physical green screen still wins on is live production — a permanent studio with controlled lighting gives the operator zero processing latency and no AI dependency. For everything else — YouTube, courses, streams, TikTok, indie film, interviews, podcasts, marketing content — the virtual approach is faster, cheaper, more portable and just as keyable. Combine both: shoot live with a green screen when you have the studio, and use this tool everywhere else.
Pro tips for clean chroma key
Use tighter feathering for chroma key
2–3px is the sweet spot. More than 5px creates a soft halo that your NLE's keyer will amplify into visible green fringes.
Contrast your clothing from your skin
Dark hair and dark clothing on bright skin key the cleanest. Avoid green clothing — even with the AI mask, your NLE might grab it during keying.
Record in Quality mode
Every frame segmented = fewer gaps and flicker in the mask. Essential for chroma key export since the editor keys every frame.
Use the Full-Body model for wide shots
Walking, standing, gesturing subjects break the upper-body model below the waist. Switch models in the AI Engine tab.
Export as WebM and convert if needed
WebM is what browsers record. Convert to MP4 or ProRes with the ToolDeck Video Converter for maximum NLE compatibility.
Match audio to your editor's sync
The exported audio is Opus in WebM. If your NLE prefers AAC, let your editor transcode on import — most do this automatically.
Who uses a virtual green screen?
YouTubers & content creators
Record in any room, key the subject out in your NLE, composite over an intro, animation, or product shot — no studio required.
VTubers & streamers
Export a green-screen clip, key it in OBS, and composite over live gameplay or a virtual avatar scene.
Course creators
Record lessons in a home office, key out the room, and place yourself over branded slides or product demos in post.
Indie filmmakers
Shoot a scene in any location, export as chroma key, and drop the subject into a 3D scene or matte painting.
Podcasters
Record an interview anywhere, then composite the speaker over a branded set or split-screen layout in your editor.
Marketing teams
Deliver clean talent footage to agency partners and editors without reshooting on a physical set.
Browser support
| Browser | Experience | Notes |
|---|---|---|
| Chrome / Edge | Excellent | Full 30 FPS segmentation with GPU acceleration and VP9 recording |
| Firefox | Very good | Fully supported; VP8 recording fallback where VP9 is unavailable |
| Safari (16.4+) | Good | Supported on Apple Silicon; enable hardware acceleration for best FPS |
| Mobile browsers | Works | Use Performance mode + 50% render scale for smooth playback |
Troubleshooting
Green halo around subject edges after keying
Lower edge feathering to 1–2px, and in your NLE raise Spill Suppression or use a small matte choke (1–2px). The pure #00FF00 makes this the cleanest possible key source.
Preview is laggy
Switch Performance Mode to Performance and Render Resolution to 50%. Record in Quality mode only if you need maximum fidelity for editing.
AI model won't load
Enable hardware acceleration in browser settings and allow CDN access (jsdelivr, googleapis) for the one-time model download.
Parts of body disappear
Lower Mask Threshold to ~0.4. If still losing edges, switch to Full-Body model for wide shots.
Green background looks blotchy or has flicker
Use Quality mode (every frame segmented) and ensure you're not recording in Performance mode. Also check that your source video isn't highly compressed.
Downloaded WebM won't import in my NLE
Some older NLEs don't support VP9. Convert the WebM to MP4 (H.264) or ProRes with the ToolDeck Video Converter — no upload required.
Recording has no audio
Enable "Include audio" in the Export tab. Camera mode needs mic permission; uploads mix the source soundtrack.
Multiple people in frame get merged
The selfie model targets one primary subject. Frame the main person centrally for the cleanest keyable export.
Virtual Green Screen Maker FAQ
How does a virtual green screen work?
The AI removes your real background and fills it with pure #00FF00. You export the clip as WebM and import it into any editor — Premiere, DaVinci, CapCut, After Effects, Final Cut — where you chroma-key out the green as if it were a physical green screen. The result is a fully editable subject layer on a clean keyable background.
Is this virtual green screen maker free?
Yes — completely free, no sign-up, no watermark on exports, no daily caps, no file-size limits.
Do I still need a physical green screen?
No. Our AI detects your silhouette automatically. You can film in any room and produce a clean chroma-key-ready export. The only thing you give up is the ability to film live with a physical key — but for recorded content, virtual beats physical almost every time.
Is my footage uploaded?
No. Everything runs locally in your browser on your GPU. Nothing is sent to a server. This means it's safe for unreleased content, client footage, and regulated-industry workflows.
What format does the export come in?
WebM (VP9 + Opus) at up to 8 Mbps, matching your source resolution × render scale. Audio is optionally mixed in. WebM is compatible with all modern NLEs and browsers; if you need MP4, convert it locally with the ToolDeck Video Converter.
Will the green match a real chroma key?
Yes — pure #00FF00 is the standard chroma-key green used by broadcast and streaming software. It keys the same way a real green screen does in Premiere, After Effects, DaVinci, Final Cut, CapCut and OBS.
Which editors can I import the export into?
Premiere, After Effects, DaVinci Resolve, Final Cut Pro, CapCut, OBS Studio, Streamlabs, and any NLE with a chroma-key or Ultra Key filter. If your editor doesn't support VP9, convert to MP4 first.
Why is edge feathering different for green-screen export?
For normal compositing, 2–4px feathering looks natural. For chroma-key export, tighter (1–3px) is better — feathering creates a soft halo of green pixels that your NLE will amplify into a visible fringe during keying.
Can I use the green-screen export for a live stream?
Yes. Feed the live canvas into OBS Virtual Camera, or record a clip and use it as a source in OBS with the Chroma Key filter. Perfect for VTubers, tutorial streamers and live podcast set compositing.
Does it work with multiple people?
The selfie model targets one primary subject. Multiple people can confuse the mask; for best results, frame the main person centrally or switch to the Full-Body model for wide group shots.
What is the difference between #00FF00 and #00FF01?
Nothing perceptually — they both look green. #00FF00 is the canonical pure green, and it's what we output. Some editors key best with slight variations, but #00FF00 works in every modern NLE with default settings.
Can I record in front of a moving video and get a green-screen output?
Yes — the tool ignores whatever background you have and replaces it with pure green. Moving background, cluttered wall, café — all become uniform green in the export.
Does the export include audio?
Yes, if you enable "Include audio" in the Export tab. Microphone from camera mode, or the source video soundtrack for uploads, is mixed into the WebM.
How do I key the green out in CapCut?
Add the clip to the timeline, click Overlay → Chroma Key, pick the green with the eyedropper, and adjust Intensity and Shadow. The pure #00FF00 keys almost perfectly with default settings.
How do I key the green out in Premiere Pro?
Apply Ultra Key to the clip, use the eyedropper on the green, then in Effect Controls adjust Matte Generation, Matte Cleanup and Spill Suppression. For the cleanest result, set Shadow to ~50 and Tolerance to ~30.
Can I use this for a VTuber setup?
Yes. Record yourself in Green Screen mode, then in OBS: add Media Source for the WebM → apply Chroma Key filter → composite with your avatar and gameplay layers. This is one of the most common use cases.
Is it safe for confidential footage?
Yes — the core design. Because processing is local and nothing is transmitted, confidential footage never touches a server. You can disconnect from the internet after the model loads.
Can I use the output commercially?
Yes. Everything you create is yours. No license restrictions, attribution requirements or watermarks on exports.
Your video stays on your device
No upload, no account. The AI model runs inside your browser using WebGL and WebAssembly. Your footage never leaves your device — you can disconnect from the internet after the model loads. Read how we keep it private.
