LED screen application skills and cases

1.1 Creative design

Take the form of an interview program as an example. In the program, the core dispatcher and host, the author of the work, and the parties repeatedly appeared. The main functions of the screen are the play of the work and the release of the Weibo information. How to make people appear on the stage from different environments, how to make VCR play more contemporary, how to make microblog information on the screen in real time, how to make the interaction between light and video is the key point of this design.

The characters appeared out of the video and came out of different environments through video packaging. After confirming the creative point, in order to ensure that the platform is closed, the gap between the screens is not seen, and a push-pull platform with a clearance of 0.5 mm has been developed. In order to maintain the absolute concealment of the car platform, in the video content, the push-pull car design is in dark processing, and the push-in does not wear the help, effectively realizes the idea that the character enters the scene from the LED screen, as shown in Fig. 6.

Figure 6 The idea of ​​the character entering the scene from the LED screen

In order to enhance the VCR playback and the sense of the microblogging wall, design a convex and concave space with a transparent texture, and generate a PNG file with a transparent channel. During the rehearsal process, the server layer overlay function is used to design the scene. Just fine. The live signals can also be stacked directly to achieve real-time online packaging output.

Modern multimedia technology can easily realize the interaction between video and lighting. When the console is programming the lighting scene, the video effect can be programmed into the scene through the multimedia server. With multi-layer overlays, large screens are more layered.

1.2 Engineering Design

Engineering design is the basic guarantee for achieving creativity. The focus of this program is on the design of the small gap push-pull platform and the multi-circuit ground lighting design for the video effect.

1.3 preliminary test

Perform visual effects analysis experiments on large screen effects. We have basically completed the creative part of the video, simulating the LED display and stage imaging part of the stage, and then cooperating with the lighting and mechanical design to verify the control and rationality of time, cost and visual effect in the initial design.

1.4 Engineering Construction

Accurate construction technology is the guarantee of design completion. After the previous integration, the final effect is the most important. The use of LED screens, stage machinery, lighting and other equipment, through the content of the creative, the visual effects presented are often pleasant surprises, but also impressive. See Figure 8.

Figure 8 shows the final effect of LED screen, stage machinery, lighting, etc.

The main points of multimedia technology application

2.1 Creativity is fundamental

The pursuit of big and empty and neglecting creativity is the misunderstanding of the current application of multimedia technology, and this phenomenon is more common. How to use technology to serve art creation is the basis of multimedia development.

2.2 The importance of hardware

The continuous improvement of hardware technology has created a better platform for artistic creation, and the equipment performance is more flexible, more convenient, more concise and cheaper.

2.3 The importance of material

The application of multimedia technology consists of two major parts: hardware and software. In addition to the input of hardware such as screens, projections, servers, consoles, etc.; the playback content contained in the software, that is, the material, is also a major investment.

2.4 The importance of broadcast control

The broadcast control is reflected in the programmability, and the good broadcast control system can be programmed quickly and conveniently according to the requirements of the creative team, as shown in Figure 14.
