One of the most common questions in film school is, “How do green screens work?” How are green screen backgrounds added into TV shows and movies?
For the most part, the process is fairly simple. It only becomes difficult when you try to hide the fact a green screen is being used, or try to set up a scene to look 100% realistic. Here is how green screens work.

What Is a Green Screen?
The term “Green Screen” is used to describe a camera and editing trick. A large canvas is placed behind a scene, and it contains a color that is not present elsewhere in the shot. The color is typically a bright shade of blue or green. During the editing session, the green screen color is keyed out of the scene. It then leaves a blank space where another image may be superimposed into the video.
Green screening doesn’t always happen in the editing room. For example, weather channels and services have used green screen in the moment. For many years, when a weather reporter was pointing at a board, the reporter couldn’t see what was on the board, only the people at home could see.
The misuse of colors sometimes led to series bloopers, such as when the weather reporter wore the same color shirt as the green screen. It sometimes resulted in part of the weather map being superimposed onto the weather reporter.
Why Do Video Makers Use Green Screen?
The most common use in the olden days was to cut down on costs. For example, rather than flying to Greece to film a scene in front of the ruins, one can use a green screen and make it appear like the participants are standing in front of the ruins.
These days, there is still a fair amount of green screen used in mainstream comedy and sitcom TV shows. This is partly due to its money-saving capacity, and partly due to people being more accepting of this sort of thing in comedy shows.
This is especially where the premise is not supposed to be taken seriously. In fact, there are many times when the fake green screen images being shown behind what is supposed to be a moving vehicle is part of the joke.
Green screen is more commonly used no mainstream TV, and to a lesser extent in movies, to fill out a scene. For example, the production company may have quickly built a seaside party set for a five-second scene.
Most props will cover the green screen, but the green screen is still present in the background to show things like clouds moving in the sky or boats moving on the ocean. It fills out a scene and makes a studio set look at little more realistic.
How Do Green Screens Work?
Before getting into the more technical stuff, think about this: you have just taken a photo, but there is an unwanted person in it. You go into MS Paint, and you can cut out all the people you want in the photo, and discard the rest.
You can discard the background and all the unwanted people. What is left over is a bunch of people, so you drop their image onto a nice background photo. When you do something like this, you are doing a similar thing that green screens do. In fact, people have been photoshopping in that way since the days of Leon Trotsky.
Green Screening Does Not Have to Include the Color Green
You can green screen by adding a certain color into the scene. Make it a color that is not seen elsewhere in the scene. Typically, this color is added as a canvas behind the screen, but it doesn’t have to work that way.
For example, you could use the color on somebody’s boots, and then edit out and change the boots in the edit. Maybe you could make the boots look like they are burning with the use of visual effects.
What Happens After You Add Your Green to the Scene?
Once you have added your color to the scene, you must record the scene as normal. Then, in the editing phase, you isolate a single color. The color you isolate is the green screen color, (whichever you chose). In the scene, you make that color transparent. This means that there are frames with transparent elements in them. This process is called chromakeying.
Once you have used chromakeying make a certain part of the frame transparent, you can replace that transparency with another image. When building a background, the image is sometimes a piece of video footage or a still image. Other times a visual effect is used such as CGI to make something appear to be in the scene, but is actually not.
How to Set Up Your Green Screen Scene in 5 Steps?
Step 1: Choose the right color
The first thing you need to do is make sure the color you choose is not present anywhere else on the scene. Even the way you light your scene can affect the colors where one color is almost reflected on another surface to create a new color. In short, you will need to do a lot of screen tests to be sure the color you pick does not appear elsewhere in the scene.
Step 2: Buying your materials
There are many pre-made green screens that you can buy. They are mostly made of a single-colored material that is non-reflective. The most common colors of a green screen background are a light green background, a dark green background and a mint green background.
Tools and Equipment to Set Up a Green Screen
All you need is something that is a single color. The color you choose it the color you key out later. For the sake of consistency, let’s say the color is green. Green is typically the color chosen, but it all depends on your scene. For example, if your set has a lot of green foliage in it, then the color may work better.
- A Projector Screen
Some people use projector screens with a green matte canvas on them. For example, a weather channel may use a projector screen and then superimpose the weather information onto the screen.
- A Large Green Canvas Background
TV studios will typically use a large green matte material that takes up an entire wall. This is used to build an entire scene behind a set. For example, the set may contain sun loungers, and the green screen shows a beach scene.
- A Large Painted Walls
Other production companies may use an entire wall that they paint in a green matte color. The trick is to then stand people in front of it so it looks like they are in different locations.
- Good Lighting
In order to avoid shadows, free-standing lights are needed. Using overhead lights alone will cause shadows to appear on the green screen. That is why large and powerful freestanding lights need to be used to fully illuminate the green screen.
Step 3: Lighting properly
Step three is the lighting, and it is burningly important that you get it right. If your green screen is not lit consistently, then different areas will show as having a different shade during the edit. Different shades of green are going to make the editing (chromakeying) process more difficult.
Step 4: Set individual lighting
The things you are green screening will not look real if they do not include their own light sources. An obvious one is if your green screen features a sky with a sun in it. In this case, you need lots of light coming from where the sun appears to be.
You also need to think about individual lighting and how it creates shadows. The objects that make up part of the green screen may be emitting their own lights. In which case, you need to make sure the objects actually emit a light so that they create the right types of light reflection and shadows on real-world objects.
Step 5: Post-editing
Step five is the editing process, and a large part involves thinking about how the green screen would interact with the other elements in the scene. Commonly forgotten elements in an indoor setting are shadows from clouds, the wind, and background noises like cars passing or dogs barking.
5 Green Screen Ideas for Each Video-Making Scenario
All green screen ideas needs to revolve around your plot that the things you wish to achieve. In many cases, green screen technology is going to save you money.
- Are there ways that green screen can save you money?
- Can you add in new locations?
- Can you add in new objects that were not previously there?
Using Green Screen to Improve a Scene
Green screens can be used to fix up a scene or improve it. Ask your how yourself scene could be improved thanks to green screening.
- Could you make your background more dynamic?
- Could you add more visual information to a screen?
- Are there things you would like to cut out of a scene using chromakeying.
Using Green Screen to Add Objects into a Scene
Would you like to add things to your scene? Perhaps you cannot afford a super car, so you create a model, scale it up, and add it over the green object you placed in your scene. Maybe you would like to add further details like computer consoles on your spaceship deck, or the stars flying by past your spaceship’s window.
- What details can you add to a scene?
- Which objects can you add to a scene to make it better?
- Can you create an atmosphere by adding something into a scene?
Using Green Screen Technology and Visual Effects
Maybe you would like to use green screen to add visual effects. Perhaps there are things that need improving. Maybe your TV show or movie features are piece of futuristic technology that has lots of moving parts. You could film a solid green object and then add the CGI animation over the green area by first making the area transparent with chromakeying.
- Would you benefit from adding animation to different objects?
- Should CGI be added into the transparent green screen areas?
- Could computer generated graphics enhance an already dynamic scene?
Be Careful When Picking What Should Be CGI Animated
Just make sure you make correct and smart choices when you decide to add in extra details with green screen. A classic example of a very bad idea was during the 2011 movie “Green Lantern,” when for some reason they added very ugly CGI eyes over the mask.
Green Screen Ideas Need Not Exist Just in Videos
The best green screen ideas are ones that occur as natural solutions to your production problems. Sometimes the problems are as simple as budget constraints, and sometimes it is a more personal problem such as trying to edit out corporate logos or branded items that you do not have the authority to use. Green screen is even used by people who are trying to master Instagram. Take the example of people who are living an “Instagram Road Lifestyle.”
In fact, in real life, there are plenty of people who are faking their Instagram images to great success. Notice the blank colors in the background, and the green seat in the image below. Using chromakeying, it is possible to make the Instagram user look as if she is living a luxurious lifestyle.
The Best Green Screen Video Editing Tools for Beginners and Pros
The truth is that many different tools can be used to edit frames and replace elements within the frame, and the use of a green screen makes the process all the easier. You could easily use the free tools Blender and GIMP to manufacture a green-screened scene. However, using such tools is rather labor intensive, and it is often easier, quicker and more efficient to use specially designed video recording and/or editing tools.
The tools that make green screening easy are often very expensive, but many of them come with a free trial that you can use prior to buying. For example, Wondershare Filmora comes with a free trial for both Microsoft and Apple desktop products. There are also tools like the VSDC Video Editor, iMovie, Virtual Dub and so forth.
Do not be fooled by article that claim they list free Chroma key or green screening tools. Firstly, the genuinely free tools, such as the open source tools like Blender, are very labor intensive. Secondly, such articles are claiming the green-screening tools are free, but they only have free trials, you will be required to pay if you want to use the tools over the long term.
The 3 Best Green Screen Video Editors

Buyer Beware When Looking For Video Editors
As mentioned earlier, a common trick is to offer you a free trial and then roll your free trial over to a paid subscription. When an editor claims to be free, you need to check just how free it really is. Another trick is to claim the tools are free, so you work on your project, and then when it is time to export you are asked for payment.
Another common trick is to offer you a free trial and then load your computer up with all types of bloatware. Plus, some video editors offer you free services, but they will add a watermark over your edited video.
In addition, if an editing tool asks you to sign in to your other accounts, such as your YouTube account or Google account, then perhaps uninstall the program. You need to do this because there is no guarantee of security with these programs, which means you cannot be sure of the safety of your passwords when you enter them into video editing tools, (especially free ones).
Conclusion - Getting it Right is the Hard Part
Now that this article has answered the question, “How do green screens work,” You are now free to try it yourself. You are going to read a lot of articles that say green screening is easy. Where it is true that the method is easy, in reality it is very difficult to get green screening right. It is just like how cooking is pretty easy, but cooking a great meal is not.
Are you finding it difficult? Are you using green screen technology in a clever way?

Why Do Video Makers Use Green Screen?
The most common use in the olden days was to cut down on costs. For example, rather than flying to Greece to film a scene in front of the ruins, one can use a green screen and make it appear like the participants are standing in front of the ruins.
These days, there is still a fair amount of green screen used in mainstream comedy and sitcom TV shows. This is partly due to its money-saving capacity, and partly due to people being more accepting of this sort of thing in comedy shows.
This is especially where the premise is not supposed to be taken seriously. In fact, there are many times when the fake green screen images being shown behind what is supposed to be a moving vehicle is part of the joke.
Green screen is more commonly used no mainstream TV, and to a lesser extent in movies, to fill out a scene. For example, the production company may have quickly built a seaside party set for a five-second scene.
Most props will cover the green screen, but the green screen is still present in the background to show things like clouds moving in the sky or boats moving on the ocean. It fills out a scene and makes a studio set look at little more realistic.
How Do Green Screens Work?
Before getting into the more technical stuff, think about this: you have just taken a photo, but there is an unwanted person in it. You go into MS Paint, and you can cut out all the people you want in the photo, and discard the rest.
You can discard the background and all the unwanted people. What is left over is a bunch of people, so you drop their image onto a nice background photo. When you do something like this, you are doing a similar thing that green screens do. In fact, people have been photoshopping in that way since the days of Leon Trotsky.
Green Screening Does Not Have to Include the Color Green
You can green screen by adding a certain color into the scene. Make it a color that is not seen elsewhere in the scene. Typically, this color is added as a canvas behind the screen, but it doesn’t have to work that way.
For example, you could use the color on somebody’s boots, and then edit out and change the boots in the edit. Maybe you could make the boots look like they are burning with the use of visual effects.
What Happens After You Add Your Green to the Scene?
Once you have added your color to the scene, you must record the scene as normal. Then, in the editing phase, you isolate a single color. The color you isolate is the green screen color, (whichever you chose). In the scene, you make that color transparent. This means that there are frames with transparent elements in them. This process is called chromakeying.
Once you have used chromakeying make a certain part of the frame transparent, you can replace that transparency with another image. When building a background, the image is sometimes a piece of video footage or a still image. Other times a visual effect is used such as CGI to make something appear to be in the scene, but is actually not.
How to Set Up Your Green Screen Scene in 5 Steps?
Step 1: Choose the right color
The first thing you need to do is make sure the color you choose is not present anywhere else on the scene. Even the way you light your scene can affect the colors where one color is almost reflected on another surface to create a new color. In short, you will need to do a lot of screen tests to be sure the color you pick does not appear elsewhere in the scene.
Step 2: Buying your materials
There are many pre-made green screens that you can buy. They are mostly made of a single-colored material that is non-reflective. The most common colors of a green screen background are a light green background, a dark green background and a mint green background.
Tools and Equipment to Set Up a Green Screen
All you need is something that is a single color. The color you choose it the color you key out later. For the sake of consistency, let’s say the color is green. Green is typically the color chosen, but it all depends on your scene. For example, if your set has a lot of green foliage in it, then the color may work better.
- A Projector Screen
Some people use projector screens with a green matte canvas on them. For example, a weather channel may use a projector screen and then superimpose the weather information onto the screen.
- A Large Green Canvas Background
TV studios will typically use a large green matte material that takes up an entire wall. This is used to build an entire scene behind a set. For example, the set may contain sun loungers, and the green screen shows a beach scene.
- A Large Painted Walls
Other production companies may use an entire wall that they paint in a green matte color. The trick is to then stand people in front of it so it looks like they are in different locations.
- Good Lighting
In order to avoid shadows, free-standing lights are needed. Using overhead lights alone will cause shadows to appear on the green screen. That is why large and powerful freestanding lights need to be used to fully illuminate the green screen.
Step 3: Lighting properly
Step three is the lighting, and it is burningly important that you get it right. If your green screen is not lit consistently, then different areas will show as having a different shade during the edit. Different shades of green are going to make the editing (chromakeying) process more difficult.
Step 4: Set individual lighting
The things you are green screening will not look real if they do not include their own light sources. An obvious one is if your green screen features a sky with a sun in it. In this case, you need lots of light coming from where the sun appears to be.
You also need to think about individual lighting and how it creates shadows. The objects that make up part of the green screen may be emitting their own lights. In which case, you need to make sure the objects actually emit a light so that they create the right types of light reflection and shadows on real-world objects.
Step 5: Post-editing
Step five is the editing process, and a large part involves thinking about how the green screen would interact with the other elements in the scene. Commonly forgotten elements in an indoor setting are shadows from clouds, the wind, and background noises like cars passing or dogs barking.
5 Green Screen Ideas for Each Video-Making Scenario
All green screen ideas needs to revolve around your plot that the things you wish to achieve. In many cases, green screen technology is going to save you money.
- Are there ways that green screen can save you money?
- Can you add in new locations?
- Can you add in new objects that were not previously there?
Using Green Screen to Improve a Scene
Green screens can be used to fix up a scene or improve it. Ask your how yourself scene could be improved thanks to green screening.
- Could you make your background more dynamic?
- Could you add more visual information to a screen?
- Are there things you would like to cut out of a scene using chromakeying.
Using Green Screen to Add Objects into a Scene
Would you like to add things to your scene? Perhaps you cannot afford a super car, so you create a model, scale it up, and add it over the green object you placed in your scene. Maybe you would like to add further details like computer consoles on your spaceship deck, or the stars flying by past your spaceship’s window.
- What details can you add to a scene?
- Which objects can you add to a scene to make it better?
- Can you create an atmosphere by adding something into a scene?
Using Green Screen Technology and Visual Effects
Maybe you would like to use green screen to add visual effects. Perhaps there are things that need improving. Maybe your TV show or movie features are piece of futuristic technology that has lots of moving parts. You could film a solid green object and then add the CGI animation over the green area by first making the area transparent with chromakeying.
- Would you benefit from adding animation to different objects?
- Should CGI be added into the transparent green screen areas?
- Could computer generated graphics enhance an already dynamic scene?
Be Careful When Picking What Should Be CGI Animated
Just make sure you make correct and smart choices when you decide to add in extra details with green screen. A classic example of a very bad idea was during the 2011 movie “Green Lantern,” when for some reason they added very ugly CGI eyes over the mask.
Green Screen Ideas Need Not Exist Just in Videos
The best green screen ideas are ones that occur as natural solutions to your production problems. Sometimes the problems are as simple as budget constraints, and sometimes it is a more personal problem such as trying to edit out corporate logos or branded items that you do not have the authority to use. Green screen is even used by people who are trying to master Instagram. Take the example of people who are living an “Instagram Road Lifestyle.”
In fact, in real life, there are plenty of people who are faking their Instagram images to great success. Notice the blank colors in the background, and the green seat in the image below. Using chromakeying, it is possible to make the Instagram user look as if she is living a luxurious lifestyle.
The Best Green Screen Video Editing Tools for Beginners and Pros
The truth is that many different tools can be used to edit frames and replace elements within the frame, and the use of a green screen makes the process all the easier. You could easily use the free tools Blender and GIMP to manufacture a green-screened scene. However, using such tools is rather labor intensive, and it is often easier, quicker and more efficient to use specially designed video recording and/or editing tools.
The tools that make green screening easy are often very expensive, but many of them come with a free trial that you can use prior to buying. For example, Wondershare Filmora comes with a free trial for both Microsoft and Apple desktop products. There are also tools like the VSDC Video Editor, iMovie, Virtual Dub and so forth.
Do not be fooled by article that claim they list free Chroma key or green screening tools. Firstly, the genuinely free tools, such as the open source tools like Blender, are very labor intensive. Secondly, such articles are claiming the green-screening tools are free, but they only have free trials, you will be required to pay if you want to use the tools over the long term.
The 3 Best Green Screen Video Editors
In reality, the front-runner in the race for best green screen video editor is the Wondershare Filmora . Adobe has some nice products that may interest some people, but the best is still Wondershare Filmora. Here are a few for green screen video editors for your consideration.

Another trick is to claim the tools are free, so you work on your project, and then when it is time to export you are asked for payment.
Another common trick is to offer you a free trial and then load your computer up with all types of bloatware. Plus, some video editors offer you free services, but they will add a watermark over your edited video.
In addition, if an editing tool asks you to sign in to your other accounts, such as your YouTube account or Google account, then perhaps uninstall the program. You need to do this because there is no guarantee of security with these programs, which means you cannot be sure of the safety of your passwords when you enter them into video editing tools, (especially free ones).

What Is a Green Screen?
The term “Green Screen” is used to describe a camera and editing trick. A large canvas is placed behind a scene, and it contains a color that is not present elsewhere in the shot. The color is typically a bright shade of blue or green. During the editing session, the green screen color is keyed out of the scene. It then leaves a blank space where another image may be superimposed into the video.
Green screening doesn’t always happen in the editing room. For example, weather channels and services have used green screen in the moment. For many years, when a weather reporter was pointing at a board, the reporter couldn’t see what was on the board, only the people at home could see.
