How do You Use a Green Screen

Common uses - why green screen?

Now, I’ll assume we’re all familiar with chroma key and what green screen is, but you might not know how accessible green screen has become. 

Turns out, you don’t have to be a million-dollar movie studio to go use Chroma Key and green screen Software. You might not need to spend any money at all. Today, using a green screen is easy and commonly used by:

  • Photographers
  • Vloggers
  • Presenters
  • YouTube stars
  • People on Zoom

But be careful! Just because people use a green screen technology doesn't mean they use it well. There are few images more distracting than a bad green screen.

Shows like Game of Thrones are ripe for green screen. Whether for dragon riding, ice-zombies, or enhancing sets, to create a new world, chances are a lot of the world will be green during production.

Similar to the use of large green dragons, green suits have become commonplace for stunts. Pictured above, instead of pretending to get attacked by animals, actors are attacked by stuntmen in green/blue. I’m not sure which is more terrifying.

Other uses aren’t quite as innovative, but very practical. With green screen on a TV set, you can later add any video/image you want. It’s a lifesaver for continuity and you wont need to secure rights before filming. Oh, it also helps if you need someone to crawl out of the TV.

Working With A Green Screen

How to use a green screen

But how do you use a green screen? Well, Like many aspects of filmmaking, green screen setup is about planning. Planning your blocking, staging, lighting, wardrobe, you name it.

Let’s cover some general dos and don'ts on how to use a green screen.


  1. Get a green backdrop. Generally, bright green is better than blue so the background is as different as possible from everything else in the shot.
  2. Make the backdrop as smooth and even as possible.
  3. Use a digital camera that shoots at minimum 24 fps with HD quality.
  4. Avoid shadows! This requires some lighting tinkering, and maybe some distance between yourself and the screen. A big shadow can seriously hinder green screen effects.
  5. Make sure the green screen lighting is even (more on this later).
  6. Match your background. For example, if using a bright, sun-filled background, you want brighter lighting on the day of the shoot.
  7. Stand 5 feet away from the green screen. This will avoid green spilling onto the border of your image/subject. Make sure you have your blocking down.
  8. Keep your camera steady. No tracking shots and no pushing in/out. At least when getting started.
  9. Sharpen the camera focus. Blurry images will have a green hue.
  10. Practice a few times before doing it for real.
  11. Start editing, and don’t be afraid to outsource to someone a little more adept in chroma key and green screen effects.

How to use a green screen


  1. Wear Green!
  2. Wear watches or anything too reflective.
  3. Stand too close to the screen. 5 feet is a good number.
  4. Shoot outside your green backdrop.
  5. No motion blur! Raise your shutter speed, motion blur may end up showing a green tint. 
  6. Get too fancy the first time. Keep it simple and start small. Learn how to work a green screen through experience.

Mistakes on how to work a green screen

Green screen setup and execution takes planning, thorough planning. It’s important to know your surroundings, scout your location, and understand exactly what you want to achieve before you get on set. Using a green screen doesn’t have to be hard, but it is if you don’t learn how to green screen first.

Now, along those dos and don’ts, lighting popped up a few times. Lighting is a crucial aspect of any shoot, but it is especially important when using a green screen.

How do you use a green screen

Remember, it’s much easier to fix things in the moment than in post. The keys to green screen lighting are:

  • Make sure the subject lighting matches the background you’re going to put them in.
  • The lighting on the screen should be balanced so there’s one consistent shade of green.
  • Avoid shadows. For the same reason as the point above.
  • The areas right around your subject are the most important.
  • Use a smartphone app to measure how even the green screen lighting is.
