Let's take sound and shadow as an example to teach you how to make dynamic green screen material.
1. Enter to cancel filtering, click Upload Clip, select the video material to be matting, and click Open, and the website will automatically matting. Or we can directly drag the video material to the website, or we can realize automatic matting.
2. After cutting and pasting the website, click "Download" and wait for the video to be downloaded.
3. Open the audio and video, click "Edit-Import Media File", select the video material just downloaded, and click "Open" to import.
4. Drag the video material to the video track, and the video will automatically add a green screen background when it sounds, and then click "* * * Enjoy-MPEG 4-Start" to render and output the dynamic green screen material.
Both the blue screen and the green screen are background screens for shooting special effects shots. Actors perform in front of blue and green screens and are photographed by cameras. The picture is processed in the computer, and the blue or green background is removed and replaced with other backgrounds.
Blue is the complementary color of human skin color, and it should be the easiest to handle with a blue screen as the background. In recent years, the green screen is more used for stunt shooting, but the fluorescent green used in the green screen is easier to separate from the foreground in the computer system, which is brighter and less prone to black edges.
Blue screen is generally used in Asia, and green screen is generally used in Europe. Mainly because Europeans (mainly Germans) have more blue eyes, it is easy to remove the actors' eyes in post-processing if they use blue screens.
