Green Screen Technology and Special Effects Make A Jaw-Dropping Video

I. Introduction to green screen technology

principle

The green screen is commonly used in film and television special effects due to its ease of separation from the foreground in computer systems. Its bright green color reduces black edges and makes it easy to “cut out”. During shooting, actors perform in front of the green screen, which is then captured by the camera. The computer processes the image by removing the green background and replacing it with the desired scene as per the script. This technology enables the realization of complex special effects scenes that are challenging to achieve through conventional shooting methods.

Application Scenario

For green screen shooting, there are real scenes and virtual scenes. Real scenes are the ones that are actually shot, while virtual scenes are added in post-processing. Many Hollywood films, like “The Avengers” and “Twilight,” utilize green screen technology.

Another example is the processing of part of the sky in outer space in “The Martian”.

In addition to the background, the green screen can also process some individual screens, such as the black dragon in “Game of Thrones”.

Commonly, there are scenes such as “Alice in Wonderland” that also have composite special effects such as scaling.

II. Application of special effects such as green screen in personal life

With the rise of social software, personal photos and videos have become crucial business cards. So, how can “green screen” technology enhance your small videos? For instance, imagine creating the illusion of being a martial arts master in your own tranquil courtyard.

Use Adobe Premiere Pro to add special effects.

Adobe Premiere is a commonly used video editing software launched by Adobe, which is compatible with various software under Adobe, and is currently widely used in various video post-productions.

1. Install and open the software.

2. Double-click the project panel to import green screen video and background image material.

3. Process the green screen lion using the following steps:

• Go to the project panel in the upper left corner.
• Click on "Effects" and then "Video Effects".
• Select "Keying" and then "Color Key".
• Drag the "Color Key" special effect to the green screen video material in timeline 2.
• Adjust the related parameters (refer to the figure below).

4. In the final preview, the green screen of the lion should be successfully removed.

2. Drag the photo material of sitting in the yard to “Track 1″ of the timeline, and adjust the mutual positions of the man and the lion. (upper right corner)

Run it, and a moving image of a “lion” appears behind the person. Does it look like a “martial arts master” practicing “qigong”?
