Editing is the process of selecting and preparing written, visual, audible, and film media used to convey information. The editing process can involve correction, condensation, organization, and many other modifications performed with an intention of producing a correct, consistent, accurate and complete work. The editing process often begins with the author's idea for the work itself, continuing as a collaboration between the author and the editor as the work is created. As such, editing can involve creative skills, human relations and a precise set of methods.
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.
