Green screens are among some of the most widely used tools in the broadcasting industry. Officially known as "Chroma keying," the technique has been used in many fields to remove backgrounds from the subject of a photo or video – particularly in the newscasting, motion picture, and video game industries, according to Wikipedia.

So why do you need it and how can you use it? Let's figure this out together!

How Does a Green Screen Work?

Broadcast productions, news stations, and content creators use green or blue screens as a solid background to customize the way they look on screen. Green screen software checks the video for green or blue tones and replaces them with any image or video.

Why green or blue screens? The answer is simple: it doesn’t match natural skin color and is easier to remove without essential parts of a picture being affected. As a result, we have beautiful special effects organically integrated with movie characters on screen that wow the audience.

You may wonder: how is this connected to our streaming setups?

The answer is quite simple: similarly, you may use a green screen to create professional backgrounds for your meetings or streams without spending thousands of dollars on a setup.

What Do You Need to Use Chroma Key Compositing?

  1. A PC or other device that you can stream from, broadcasting tools like Melon, and an external camera
  2. A light source - a natural one if you stream during the day. Additional lighting may be needed to have solid, even background
  3. Live streaming software of your choice
  4. Green or blue screen background.
