Painting to Create a Green Screen
If you have a fixed space and want to make a green screen, painting can be a long-term solution. The cost per foot is comparatively low when it comes to painting. Unlike a roll of cloth, you will be able to cover a larger area for a small amount of cost.
Apart from saving you money, it will also allow you to make any shape a keyable surface in a small amount of time. Boxes, furniture, etc. can be painted to be used on set.
However, like cloth, green screen paint might get dusky. Nevertheless, the paint can withstand limited cleaning. If little scrubbing does not help, you can lay down a new coat of paint over the spotted areas. But with a painted green screen, you will not have to worry about wrinkles.

How to Set Up a Green Screen?
In case you cannot afford to buy a green screen, you can create one yourself.
So, you have got yourself a green screen and are all set to shoot. No matter if you are making a commercial or a high-budget film, with the correct setup, your final cut will look professional. Here are a few steps that you need to follow to use your green screen and create a realistic scene.
1. Setup and Setting
Choosing a green location is the most important step. So, you need to look for a large space backdrop. Check if there is equipment for lights and a camera.
Now, place the chroma key fixture on a stable and flat surface to keep it from falling while you are filming.
Next, you have to secure the backdrop. You can use sandbags or weights on the sides or at the feet of the green cloth. This secures the green screen in the right position.
2. Lighting the Green Screen
When you use a green screen, it is necessary to use stronger lighting. This helps in creating a solid color background. It is important to create a consistent shade of green as it makes processing the effects of Chroma Key much easier. Use lights from the top and side where they are going to be out of the shot. Since you are using DIY cloth, make sure that the surface is as smooth as possible.
3. Lightning the Subject
Make sure that you reduce the shadows actors cast. For this, you can use overhead lighting. You can also ask them to stand at a distance from the screen. Now, separate the subject from the background by adding a few feet distance. This will stop a green edge that the actor’s shadow creates. You should ascertain that the actors aren’t wearing anything close to bright green. If they do, they are going to disappear into the background.
4. Position the Cameras and Actors
Direct the subject to stand a few feet away from the screen but make sure that they are not far back so that their feet are surrounded by the green screen. The ideal position is the horizontal center. This gives the performer enough space to move around, and no part of their body is out of the colorful backdrop.
Next, place the camera so that the green screen covers the shot in the viewfinder. But make sure that the sandbags and lights are out of sight. In case you are shooting in a single-angle, you will have to get the light right just once. Nevertheless, when you give your subject more than one angle, the screen green color should be consistent in every frame.
In case creating a green screen sounds too much hassle, you can give up on the idea and use the chroma key effect on a video editor like FilmoraX. It supports all video formats and can easily chroma key the video background. It blends the video seamlessly with new backgrounds.
