CSO - Chroma Key

Chroma key compositing (or chroma keying) is a technique for compositing (layering) two images together. A color range in the top layer is made transparent, revealing another image behind. The chroma keying technique is commonly used in video production and post-production.

This technique is also referred to as color keying, color-separation overlay (CSO or greenscreen. It is commonly used for weather forecast broadcasts, wherein the news presenter appears to be standing in front of a large map during live television newscasts, but in a television studio it is actually a large green background.

The meteorologist stands in front of a greenscreen, and then different weather maps are added on those parts in the image where the color is green. If the meteorologist wears green clothes, his clothes will be replaced with the background video. This is because green is considered the colour least like skin tone  This technique is also used in the entertainment industry for special effects.

Software is available today, such as Pinnacle Studio, which makes it possible and relatively easy for the average home computer user to create videos using greenscreens with the Chromakey function.
