How to use the green screen

What is the green screen

Il green screen (green screen), also called chroma key (color key inlay) is a technique used to replace the background in a video. It is a green cloth that acts as a background while turning and which then allows it to be easily replaced with the desired background, thanks to the use of the appropriate function of the video or photo editing programs.


You may have also seen the blue screen, which has been replaced by the green one because it is better for digital equipment. The concept on which the green screen technique is based is the replacement of the background which, being of a uniform color, makes the subject of the video easily separable from the background itself. This subsequent operation is done during the assembly phase, with special programs.


On the market there are many types of green screens: some very simple, which cost even less than 20 euros, and others more professional, perhaps equipped with a frame and anti-crease system, which can even exceed 100 euros in cost. Then there are complete kits with lights, green screen and support, which I highly recommend you to consider if you are a beginner: having the right support is very important, because the green screen will be positioned better and if well lit it will make the operation. replacement of the background much easier and free of imperfections.

Below, you will find some green screens and kits that I recommend you consider. Below, we will then see how to exploit them from computers, smartphones and tablets.

How the green screen works

The first step you need to take is to shoot your video with the background green screen by following some technical precautions, such as those listed below. Next, I'll show you how to use the green screen in the main video editing programs for PC, smartphone and tablet, in order to customize the background.



Preliminary information

The first operation to be performed, as already mentioned, is to set up the set to shoot the video with the green screen. To ensure that the editing operation proceeds smoothly, you need to have some small but fundamental precautions.

First, the green screen has to be tightly stretched, with no ripples or shadows and it must cover the whole frame well. It is therefore advisable to purchase the green screen with a structure that supports it. It is also essential that thelighting is very good, diffused and does not create shadows on the green screen, which would complicate the subsequent editing work.

Then it is necessary avoid wearing colors similar to the green of the green screen, unless you want to voluntarily be part of the background and "disappear" into it. Once the video is shot, you can move on to the editing operation, replacing the green screen background with the background you like best. Now let's see in detail the programs to use. For further information, you can search on Google for specific guides on the positioning of the lights.

Almost needless to say that the shots must be done with good quality equipment: I recommend a good video camera or a good DSLR; if you really want, however, you can also turn to a camera phone, that is a smartphone with a good photographic sector: you will find many tips for purchasing these devices in the guides that I have just linked to you. Having said that, let's move on to processing the videos in the various editing software.
