Building a green screen studio at home really does not require more than a green fabric as background and an app or application on your laptop. Here we go through what a green screen is, how it works to set up your own home and what options are available if you want to use a professional studio.

What is a green screen?

A green screen is a green background that can be used to replace the background behind an object or person with a virtual produced background. Green screens are often used in film recordings or studio productions. Depending on the color, you can talk about a green or blues screen, the important thing is that the background does not match the color of the objects or people. The background can be made of fabric or painted directly on the wall, as in larger studios.

What equipment do you need for building a simple green screen studio?

Today it is very easy to Create a green screen setup yourself at home to take your webinars to the next level or make sure your business studio can be virtually customized to infinitely many environments. All you need for a simple green screen studio is:

  • A camera or smartphone
  • A green screen - the background itself that can be both portable and relatively inexpensive
  • Lights - here it is important to have a separate light source for both the background and the object
  • Software or webinar tools - e.g. OBS for live broadcast or Univid, where you can easily use so-called chroma keying to replace a certain color with a virtual image or environment

5 tips to keep in mind when broadcasting live or recording with a green screen

By object we mean what is in the foreground. So the person or thing you want to appear in front of the virtual background.

1. Light up your background first, then the object

One of the biggest mistakes you can make when working with a green screen is to light up the background and person with the same lamp. Be sure to work with two separate lights, and start by lighting the background with an even light that is not too bright.

2. A "green screen kit" can cause extra work

A too cheap green screen kit can make the job of removing the background in your app or meeting tool much more difficult, as they often do not contain several lights that can illuminate both the background and the object at the same time. If you buy a ready-made kit, make sure that you have at least 2 lights and that the background can be completely smooth.

3. Wear clothes that contrast with green

Do not wear green clothes, as you will blend into the background. The chroma key will make everything green disappear, so remember to have clothes, jewelry, etc. that do not reflect and preferably are a so-called complementary color to green - ie. red, orange or purple are optimal.

4. Separate the background from the object

By leaving the background some distance away from the object, you eliminate the risk of hard shadows from the object against the background. If the object is right in front of the green screen, it will be almost impossible to get an even and nicely lit background. Have a few meters between the object and the background, and you can get a nice lamp that focuses entirely on illuminating the background in between.

5. If you have the option of setting the aperture, use a low aperture number

For those who stream or film with a slightly larger system camera with the option to set the aperture - be sure to use a low aperture number (ie a large aperture), which causes the depth of field to be short and the object to pop from the background. The background is also more uniform in color and softer, which makes it even easier to key out the object from the background in your software then.
