Have you ever looked at the cool movie effects and wondered how they pull that off?

Do not worry; we have got the answer to your questions.

We might even help you in making such cool effects on your own.

The tool used to achieve this is known as the Chroma key. The Chroma Key transition uses a green screen to incorporate images and videos in a scene.

Part1. What is a Green Screen?

The green screen is an important editing tool used by editors to add effects. As the name suggests, the green screen is a green monochrome backdrop. This is essential for the chroma key to work and for the editor to show his magic on screen.

Part2. How Does it Work?

You must be wondering how a simple backdrop can change the entire outlook of a video. The key to changing the monochromatic green backdrop into a display of marvel is the chroma key.

Once the footage has been shot using the green screen in the background. The real work begins in the post-production phase. You take footage and layer them upon each other. One is the video with the green screen, and the other is pre-recorded footage.

The Chroma Key makes the green background transparent, making it seem as if the second footage is now the background in the footage that had the green screen. This assimilation helps in merging footage, making it seem flawless.

Part3. How to Make Your Own DIY Green Screen?

As stated before, a Chroma Key cannot work successfully without the existence of a Green Screen. If you want to use Chrome Key transitions without the help of a professional, you would need to make your own Green Screen.

There are two very simple steps to creating your very own green screen.

  1. First, you need to get a simple sheet, cloth, or paper that is non-glossy and seamless. Then paint it vivid green.
  2. The second step is to hang it as your backdrop, using a stand or hooks, whatever is convenient for you.

With the use of these straightforward two steps, you can have your very own cheap green screen. Just make sure that the paint you have applied is uniform all across the platform of your backdrop.

Part4. How to Use the Green Screen?

Once you have set up your green screen, you need to understand how to put it to use. The Chroma Key transition videos can be pretty challenging to shoot. To help you guys, we will give you simple tips on how to get the best results.

1) Backdrop

The first thing you would need to set up is the green screen itself. While doing so, you need to keep in mind some very simple things.

The surface needs to be completely smooth; it is advised to remove any sorts of creases. The creases can create a different shade when brought under lighting. This will cause unnecessary hindrance in the editing process later on.

You should also ensure that the actors are not wearing any green cloth that resonates with the green screen. If this happens, they will merge with the edited background.

2) Lighting

Lighting is an integral part of regular videos, but its importance increases when using a green screen. The Chroma Key works best when the green screen is consistent and monotone, which means the lighting should remain the same as long as the green screen is in use.

Soft diffused lights are the best choice when it comes to lighting a green screen. These types of lights eliminate shadows and hotspots, which gives a smoother look to the final product. Diffusion filters are a great way of ensuring this type of lighting.

Since the lighting is done from multiple angles to eliminate shadows, use the same light source to ensure consistency. An extra tip would be to light your actors and green light separately to avoid other shadows.

3) Camera Settings

Your camera might not be the direct tool that utilizes the green screen. Still, it is essential to capture all the shots with the green screen in them. We will give you some key tips regarding the necessary settings.

Basic Settings

It would help if you kept your shutter speed to either 1/80 or 1/100 to minimize your motion blur. Also, to smoothen out your screen with a slight blur, set the aperture at f/4 to f/5.4.

Exposure Settings

Your ISO should be kept low, considering that you have already set proper lighting. The low ISO helps in avoiding grainy and noisy footage.

Focal Length Settings

Your focal length should correspond with the focal length of your recorded footage and the background footage to be added. Even if stock footage is to be added, it should be reviewed beforehand to set the green screen footage to match it.

Quality Settings

You should prefer the highest recordable quality. Regardless of the device you are using, 1080p is excellent, and 4K is the best out of the entire lot.

4) General Set up

The first thing is a sturdy tripod stand so that you have steady footage. And secondly, you need to ensure that the actors have ample space between them and the screen to avoid shadows.

Keeping all these tips in mind, using a green screen becomes much more manageable.
