Green Screen Effects
ALIVE includes a dedicated Green Screen effect that lets you place your guests in front of any background — no physical green screen required.
How It Works
The Green Screen effect uses AI-powered subject segmentation to detect your guests and replace the background with any image you upload. Unlike traditional chroma key, there's no color-based detection — ALIVE uses machine learning models that intelligently identify the human subject and separate them from whatever is behind them, regardless of background color.
- You upload background images — the scenes you want your guests placed into
- The AI segments the subject using trained ML models, isolating them from the background
- Your uploaded background is composited behind the guest automatically
Because this is AI segmentation (not chroma key), there's no color spill, no lighting nightmares, and no wrinkled green fabric. It works with any backdrop — plain wall, busy room, outdoors, anywhere.
Green screen effects use 5 credits per photo (~$0.05) — significantly less than standard AI style effects. Processing is fast because segmentation runs locally on the device.
Setting Up Green Screen
- Go to the Effects tab
- Find the Green Screen effect
- Upload one or more background images — these are the backgrounds guests will appear in front of
- Enable the effect for your events
Benefits Over Traditional Green Screen
Feature | Traditional Chroma Key | ALIVE Green Screen |
|---|---|---|
Technology | Color detection (green/blue pixels) | AI subject segmentation (ML models) |
Physical screen needed | Yes | No |
Precise lighting required | Yes — uneven lighting causes artifacts | No — works in any lighting |
Color spill on subjects | Common issue | Not applicable — no color detection |
Works with any backdrop | No — green/blue only | Yes — any backdrop, any color |
Guests wearing green? | Disaster | No problem — AI detects people, not colors |
Setup time | 30+ minutes | Under 2 minutes |
That said, a clean, consistent background behind your guests gives the AI even better segmentation results — but it's not required. The ML models are trained to detect people accurately even in cluttered environments.
Tips
- Subject separation matters — The AI works best when there's clear separation between the guest and the background. Avoid busy, cluttered backdrops behind your guests when possible.
- Test before the event — Always run a few test shots with your chosen background images before going live.
- Build a library — Collect background images for different event types so you can swap them quickly between gigs.
Use Case Ideas
- Corporate events — Place guests in front of the company HQ, a branded cityscape, or a futuristic office
- Weddings — Transport guests to a vineyard, a sunset beach, or a flower garden
- Themed parties — Drop guests into outer space, a red carpet, or a vintage postcard
- Product launches — Put guests alongside the new product in a stylized studio setting
The only limit is your background image collection. Build a library and swap them between events for endless variety.
Re-Running Green Screen on Past Sessions
Because source photos stay available in the Sessions list, you can re-apply green screen with a different background to any past session at any time — even after the event. Open the session, tap the actions menu, and pick Re-run green screen. The photos come back out composited against the new background.
This is especially useful for post-event upsells: a client can pick a different scene after the fact, and you can deliver a refreshed set without recapturing anything.
