luminance keying

In video editing, luminance keying is setting the brightness level, and all brighter or darker pixels from the set level are turned off and will be transparent. A second clip or image can be inserted behind to show where the pixels have been turned off. Luminance keying is used when working with grayscale images.

Compare with chroma key, which uses colors instead of brightness for transparency.
