“It is web-based, has a simple interface and is easy to use.” We promise it’s worth it!

What Is Chroma Key?

In the words of professional filmmaker Colin Dougan:

“Chroma keying is using color information to select a very specific range of colors and isolate them. The idea is to utilize the contrast in colors to shift reality and cut out subjects from a background and place them somewhere completely different.”

Chroma keying or chroma key compositing is a popular visual effects technique. It allows for two separate images or video streams to be layered together based on color hues. The end result is the ability to make foreground color ranges transparent allowing for different backgrounds to be used. This is what people mean when they describe using a green or blue screen.

This allows for presentations such as news reports and weather forecasts to use a virtual background with live videos and data. In the world of online streaming, things are no different. Many broadcasters use a green screen to remove the background or use a custom background image.

Using a green screen can dramatically transform your broadcast. It makes your content appear much more professional.

The Benefits of Using a Green Screen

Using a live green screen opens you up to a lot more options as a content creator. Here are some of the key benefits that a green screen can grant you.

With Green ScreenWithout Green Screen
Broadcast LocationDoesn’t require travel. Background from different locations can be applied instantly, even animatedRequires you to travel to desired locations which can be expensive and time-consuming
Creates a Professional ImageCustomize the backdrop of your office space giving a professional appearance to your environmentCan be expensive to create a visually impressive physical streaming environment
Engaging contentYou can integrate interactive elements to your green screen which wouldn’t be otherwise possible.Limited interaction with your audience
ScenesCombined with scenes, you can create some professional virtual spacesLimited to basic scene switching without the control you get from a green screen


We will use OBS as an example here, but other green screen software for streaming will work in a similar way.

Once you have your recording space ready, you can then move on to configuring your software. Then add your video capture device under Source.

You can then choose either a looped video or an image that will be used as a background. Just make sure that your video capture device is listed on top of your chosen background or video.

Now add the chroma key. First, right-click on your added Video Capture Device under Sources. Then click on Filters located towards the bottom of the list. Once the filter box has appeared, click on the + icon at the bottom left of the window. Then select Chroma Key.

Yes! OBS is very easy to configure for green screens and chroma key. The chroma key feature can be accessed by right-clicking on your Video Capture Device and selecting Filters.

You can easily use a green screen when broadcasting live online. You just need to make sure you have a flat green screen that is consistent in color, and adequately lit. Then you configure your chroma key software and make adjustments until you are happy with the visual quality of the effect.

Green screen live streaming really isn’t too difficult and can dramatically transform your content. As your streams are more visually varied with the use of a green screen, your audience becomes more engaged.

With green screens, it can be as cheap or expensive as you like. If you want to just get a green background initially that costs hardly anything with standard room lighting, you can. Of course, the results won’t be amazing, but it's a starting point.

If you want to broadcast using a green screen correctly, it can quickly become expensive. In addition to any fees for your software of choice, you also have to think about lighting, cameras, and having the space available.

Green screens range from a few dollars all the way up to thousands of dollars for full kits.

The best way to live stream with green screens is to start with something basic and scale upwards to something more expensive. This will allow you to become more familiar with the method without spending too much money at the start.


Using green screens and chroma key software are great ways to bring a new professional look and feel to your streams. There are a number of different software options that provide chroma key support, and the best ones we have covered above.

One thing to keep in mind when choosing your chroma key software is pricing. Some can be quite expensive or require a subscription. OBS is free chroma key software for live streaming that also functions as a software encoder. This makes it a popular choice amongst broadcasters. If you are ready to invest in green screen programs, any of the above will work and you will get the added benefits of good customer service, ease of use, and premium features.

You don’t have to be technically minded to get everything working with green screen software streaming. We’ve written a beginner-friendly guide on how to use green screen backgrounds in your videos! There are also some great YouTube tutorials on how to configure your green screen setup from beginning to end. You should now be ready to choose your chroma key software for live streaming!
