In this video we learn how to use the chroma key tool in Lightworks 14.5. It is a very handy tool as it allows you to remove certain colours from a clip, allowing you to overlay that clip onto a new background.
The colour removed is usually a lurid green, known as chroma key green. This colour is used because of its rare use and does not occur naturally.
