Have you ever wondered how movies take place in unrealistic settings where the background is clearly an imaginary world? This is made possible by a technique called chroma keying. In this article, you will learn about how chroma keying works and how you can utilize it in your own creations.
What is Chroma Keying?
How is it accomplished?
Since Chroma Key works by removing one color from a video, one would need a solid background color. Perhaps you have heard of a green screen. Although the screen does not have to be green because chroma key software can remove any color, usually green is used because of its contrast to what people are usually wearing. After a video is taken with a background of a solid color, the effect is applied in a software. Personally, I use Adobe Premiere Pro, the top-rated video editor utilized by professionals in the movie industry. Other options include Sony Vegas, or simply iMovie (not the best option). If you want to chroma key at home, I would recommend Adobe Premiere Pro for experienced editors OR Adobe Premiere Elements for beginners. The great thing about Elements is that it has options to increase the complexity of the interface based on your editing skill. Anyway, once the background is removed, any other background can be substituted.
There are generally two types of colors used for chroma key. To determine which color to use, movie directors examine the scene to choose. For example, if the color blue is used in the scene, the set would have a green chroma key screen. The same is true for the opposite. One downside of the green colored screen is that green is a more reflective color, so it may not be suitable for some applications.
