Definition
Compositing is the act of combining two images or video sequences, producing a new image or video sequence. There are several techniques to composite two images (or video frames): alpha matte, gradient-domain blending, deep compositing, multiply, overlay and screen modes, etc.
Chroma keying is the name of one of such techniques which uses color hues (chroma) to guide the compositing process. A portion of the target image is selected (based on a color or a range of colors) and substituted by the image to be inserted. This technique is widely adopted in video editing and postproduction.
Origin of the Terms
Traditionally, both in TV and films, there have been four basic compositing techniques: matting, physical compositing, background projection, and multiple exposure.
Mattingis currently the most widespread technique and corresponds to the general definition given above. Digital compositing...
