Concept of Visual Effect
Making visual effect aims to make the screen of video more attractive and realistic. However, operating special effect applications is a highly skilled and very time consuming task.
Special effect application
It is similar to most video editing applications. The difference is that After Effects is tailored for working with complex video compositions and effects rather than straightforward "cutting" jobs. Commonly used applications are shown below:
- Adobe After Effect
- Apple Motion
- Apple Shake
Composing
It means to compose 2 or more shots together, it may:
Video + Video

 |
 |
Video 1 |
Video 2 |
Video + Video |
Video + Image
 |

 |

Video + Image |
Video + 2D / 3D Animation
 |

 |

2D / 3D Animation |
Video + 2D / 3D Animation |
You also may Video + Video + image + 2D + 3D... why do you need to do composing? Because you can’t shoot the object or background in location studio or impossible.
Chrome Key (Blue or Green screen)
Why do we not use red screen? When you are shooting a man, red screen should not be considered because the color range is close to skin tone. It results some body parts of the actor may be removed (or made transparent), revealing another image behind them. Therefore, the colors least like skin tone are preferred, i.e. blue and green. Moreover, keep in mind that wearing in blue is not allowed while a blue screen is being used. This guideline also works for green screen.
