Nowadays, junior high school students are also in the age of video editing. If they have a smartphone, they can edit it with the application.
Some free apps can also perform chroma key composition. You can definitely use any commercial video editing software. And it’s easy.
Chroma key composition is an edit that often takes a picture of a green curtain in the background and changes the background. By the way, green is used most often because it does not cover the color of the body, but any color can be combined if it does not cover the color of the subject. Green is the most safe.
By the way, I heard from a friend that chromakey synthesis can be done with grass in the park. As a hypothesis, it could probably be done, but I didn’t think it would look very beautiful, so I decided to actually test it.

About verification content
I took a picture of the above turf. Delete the grass in this photo, leaving only the signboard. I will put the signboard on the next picture of the sea.
Import images into Power Director.
Then remove the background grass from the image.
Insert the image of the sea. A signboard is on the red arrow.
What is the verification result?
Can you can do it or not？ Yes, you can.
However, there are shades of color on the lawn. If you do not shoot well on the dark green grass, you will get unevenness.
I was particularly concerned about the borders, so I am blurring the borders white. On the contrary, it may be strange. If you are good at editing, you may be able to compose a little better.
The result is “I can synthesize, but I do not recommend”.
You can do it on the lawn if you don’t care about quality. However, it may be better to use a wall painted in one color, rather than even on the lawn.
Even in the room, a curtain or a bed sheet without a pattern can be synthesized more beautifully. I think we should look for something with the same color around us.
I recommend you to purchase it on Amazon. I think size is important, and I don’t think the price is so important. I have purchased some of them, but I did not feel the difference in the editing itself depending on the price.
I am shooting like the image below, but I am using different cloth for the right and left. Both are purchased on Amazon and the prices are different. But I don’t see any difference in the quality of editing.
Preparation for chroma key composition is troublesome. Many people use it as a curtain in the room. Enjoy video editing and chroma key composition while trying out various things!
