EVIL SANTA CLAUS
Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring gifts during the late evening and overnight hours on Christmas Eve to "nice" children, and either coal or nothing to "naughty" children. He is said to accomplish this with the aid of Christmas elves, who make the toys in his North Pole workshop, and with the aid of flying reindeer who pull his sleigh through the air. The modern figure of Santa is based on folklore traditions surrounding Saint Nicholas, the English figure of Father Christmas, and the Dutch figure of Sinterklaas.
Chroma key compositing, or chroma keying, is a special effects / post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture and videogame industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen – chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate the color used as the backing.
