CHROMAKEY

Using Chromakey you can combine two completely separate images to create a composite image that might be impossible to create any other way.

You’ve probably seen the chromakey effect used in television weather reports. The weather person stands in front of a “blue screen” (a solid blue background) and the weather map then keys onto the background from some other source.

Chromakey combines two sources to create a composite image.

1One source has a solid colored

background, such as a blue screen.

2The other source can be any video

image.

signal from the second image. The second image replaces the background only where the designated color appears.

Chromakey requires careful preparation of the input sources to achieve the desired effect. Keep the following points in mind:
