Compositing is the combining of visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. live action shooting for compositing is variously called  “blue screen”, “green screen” and other names.

Matchmove

Match moving has two forms. Some compositing programs, such as skake, adobe after effects, and discert combistion, include two-dimensional motion tracking capabilities. Two dimensional match moving only tracks features in two-dimensional space, without any concern to camera movement or distortion. It can be used to add motion blur or image stabilization effects to footage. This technique is sufficient to create realistic effects when the original footage does not include major changes in camera perspective. For example, a billboard deep in the background of a shot can often be replaced using two-dimensional tracking.
