Intended Audience: Hosts, Content Creators, Brand Teams
Purpose: Help merchants use a green screen to create clean, branded backgrounds that make livestreams and shoppable videos look professional --- without needing a purpose-built studio.
Why Use a Green Screen?
A green screen lets you replace your real background with any image or video during a livestream or recorded clip. Done well, it:
- Hides a cluttered or off-brand environment
- Puts your logo, product imagery, or a lifestyle scene behind you
- Keeps every stream visually consistent, wherever you're filming
- Gives your brand a polished, studio-quality look without a studio budget
For live shopping specifically, a clean background keeps your viewers' attention on you and the products --- not the mess behind you.
What You Need
The green screen itself:
- A fabric or vinyl green screen panel (from ~$30 on Amazon)
- Large enough to fill the frame behind you --- typically at least 5 ft wide × 7 ft tall for a standing or seated host
- Collapsible pop-up frames work well for brands that don't have a permanent setup
Lighting for the green screen:
- At least two lights --- one for you, one for the screen (see below)
- Separate lighting is non-negotiable; it's what makes the key clean
Streaming or editing software:
- OBS Studio (free) --- use the Chroma Key filter on your video source
- Zoom --- built-in virtual background with "I have a green screen" enabled
- Streamlabs , Ecamm Live, or similar tools --- all support chroma key
If you're streaming to LyveCom via OBS, you can add the chroma key effect directly in OBS before the signal reaches LyveCom. See the OBS Setup Guide for how to configure OBS with your LyveCom stream key.
Step 1: Set Up Your Green Screen
- Hang or mount the screen so it sits flat and wrinkle-free. Creases create shadows that break the key.
- Position it at least 3--4 feet behind you. The more distance between you and the screen, the easier it is for the software to separate you from it cleanly.
- Make sure the screen fills the entire background visible in your camera frame --- check your preview before going live.
Quick tip: If your screen has visible wrinkles, iron it on a low heat or mist it lightly with water and let it dry taut.
Step 2: Light the Screen Separately
This is the most important step. Uneven lighting on the green screen is the number-one cause of patchy, spill-y results.
- Light the screen evenly. Two lights at 45° angles on either side of the screen work well. Aim for consistent brightness across the whole panel --- no hot spots, no dark edges.
- Keep screen lighting separate from your face lighting. Don't let the same light source illuminate both you and the screen.
- Avoid green spill on yourself. Spill happens when green light bounces off the screen onto your skin or clothing. Increasing the distance between you and the screen reduces spill significantly.

Step 3: Apply the Chroma Key in OBS
If you're using OBS to stream to LyveCom:
- In OBS, right-click your video source in the Sources panel and select Filters.
- Click the + button and choose Chroma Key.
- Set Key Color Type to Green.
- Adjust Similarity upward until the green disappears, then dial it back slightly to avoid clipping your edges.
- Use Smoothness to soften the edge between you and the background.
- Check your preview --- hair and fine details should look clean. If they're getting cut off, reduce Similarity slightly.
Tip: OBS also lets you add a background image as a separate source. Place it below your video source in the Sources list so it appears behind you.
What to Wear (and What to Avoid)
- Avoid green or lime clothing. Any shade of green close to your screen colour will be keyed out, making parts of you disappear.
- Avoid shiny, reflective fabrics. They can pick up the green tint from the screen.
- Solid, saturated colours work best --- deep blues, reds, blacks, and whites show up clearly against a virtual background.
- Glasses wearers: Glasses can cause edge artefacts. Position yourself slightly further from the screen and reduce the Similarity value in your settings until your frames look clean.
Choosing Your Virtual Background
Your background should support your brand --- not distract from it.
Good choices:
- A clean, on-brand still image (your logo, a lifestyle photo, a product flat-lay)
- A subtle looping animation or branded motion graphic
- A simulated showroom image that matches your product category
Avoid:
- Busy or cluttered backgrounds that compete with you and your products
- Very dark backgrounds that make it hard to see product details
- Backgrounds with small, fine patterns that look noisy on camera
File format: For still images, use a high-resolution PNG or JPG at 1080 × 1920 px (portrait) to match LyveCom's vertical streaming format.
Quick Pre-Stream Checklist
