Embodiment Construction

[0061] The following is attached Figure 1-4 The application is described in further detail.

[0062] Embodiment 1 of the present application discloses a synthesis method of LED background and green screen shooting, and the specific steps are as follows:

[0063] Build LED large screen 1, and transmit the LED background to be played to LED large screen 1 according to the video requirements.

[0064] Set the curtain shooting frame rate (in this embodiment, the curtain shooting frame rate is set to 24), and adjust the frame rate of the large LED screen 1 to x times the curtain shooting frame rate (x in this embodiment is 2).

[0065] Control the frame rate of the camera to be the same as that of the large LED screen 1, and realize the frame rate of the camera to be the same as that of the large LED screen 1 through GENLOCK.

[0066] Shoot a movie where the curtain background alternates with the LED background. Divide the playback content of LED large screen 1 according to the...

Abstract

The invention relates to an LED background and green screen shooting synthesis method and system, and belongs to the technical field of film and television work processing. The method comprises the following steps: building an LED large screen; setting a curtain shooting frame rate, and adjusting the frame rate of the LED large screen to be x times of the curtain shooting frame rate; controlling the shooting frame rate of the camera to be the same as the frame rate of the LED large screen; shooting a film in which the curtain background and the LED background alternately appear; and processing the shot background. The method has the advantages of the curtain and the LED background at the same time, and can avoid the defects of the curtain and the LED background.

Description

technical field [0001] The invention relates to the technical field of film and television works processing, in particular to a method and system for shooting and synthesizing LED background and green screen. Background technique [0002] At present, many film and television works need to use the background synthesis technology in the shooting process. In addition to the traditional curtain, the background used in the background synthesis technology now has an LED background. Compared with the traditional curtain, the LED background has a higher frame rate and is easier to adjust. deal with. However, the screen is more detailed than the LED background, and the LED background is also prone to moiré, which affects the composite image effect. The background curtain generally includes blue screen and green screen, blue screen is usually used in Asia, and green screen is usually used in Europe. [0003] The above-mentioned prior art solutions have the following defects: the cur...
