What Is Chroma Key: Meaning, Purpose And Benefits

It’s no mystery that the chroma-key green screen is the hot new buzz in the film industry. It has amazing possibilities for creating normally impossible shots. Before discussing its purpose in detail, let’s discuss chroma keying first.

Introduction To Chroma Key

Chroma keying is a technique commonly referred to as "green screen" in the industry. For decades, they have been a big part of making movie magic. It is considered a very popular tool in films to combine different shots and create an illusion or visual effect. This allows you to put real people into unreal environments.

Green screens are a great asset for filmmakers, and whether you are just starting your filmmaking journey or creating content on YouTube, green screens are a great way to heighten your content's production value. However, you can get a green screen effect from any material as long as it's the right color green. With more sophisticated tools and improved visual effects, short film producers can now use chroma keys to tell more elaborate stories than ever.

What Is The Green Screen Made Of?

Ideally, the green screen is made of stretchable synthetic nylon fabric or muslin cloth. These types of materials absorb light and are lightweight yet thick. So no matter what option you choose, the secret to pulling a good clean key is to find a material close to digital green and make sure you do not use a fabric that wrinkles easily and is see-through, like cotton. The digital green color is brighter than the original chroma-key green version and is designed to be read more easily by the camera's imaging sensors.

Purpose Of Chroma Keying

If you have ever wondered why we always use the color green and not pink, yellow, or purple whenever we pull a chroma key, there are a couple of important reasons. The first reason is that the green color does not naturally occur in human skin tone, so it is easily selected and replaced during the editing process. Using a warmer hue like red or orange could lead to unintended effects, which we do not want. The second reason has to do with the imaging sensor of the camera. Most digital sensors use a Bayer pattern, which has twice the number of green photo sites than red or blue to capture luminance. This makes modern digital cameras much more sensitive to the green part of the spectrum, making pulling a picture from the green screen easier.

Chroma keying can increase your conversions and enhance your reputation. You can show your audience a level of professionalism they have never seen in your market. Avoid costly video editing by picking the right film making services for your client and your business.
