Therefore, in almost all large-scale evening parties, the dance design of the evening party will be regarded as the first important work after the completion of the project. There are many kinds of large-scale evening shows. Almost all directors hope that the dance performance of the party can be flexible and changeable to meet the special needs of synchronization of dance beauty and program content during the party. With the emergence and popularization of LED technology, many big producers have seen the best opportunity to realize their dreams.

Especially in recent years, the continuous upgrading of LED technology has enabled large producers to use a variety of flexible LED materials to produce LED dance scenes with various curved effects while realizing large-scale LED video. Therefore, the audience has also seen the wide application of LEDs in large-scale evening performances. The most typical example is the annual CCTV Spring Festival Gala.

The use of LED video walls has gradually transitioned from the earliest medium and large-area main screen plus secondary screens on both sides to the comprehensive utilization of panoramic video walls and omnidirectional three-dimensional video walls. In the past, only CCTV has the strength to build LED stage has gradually appeared in many provinces and cities in the evening party. However, convenient technical means do not really mean high efficiency. The comprehensive use of high-tech methods on the stage does not mean that the level of stage performance is truly improved. Throughout the production of large-scale evening parties in China, the author combined with my own experience in large-scale evening parties, and summarized the following misunderstandings when using the video wall dominated by large-scale evening parties:

1. The misuse of reality show images has led to a huge conflict between the beauty of film and television dance and the sense of form in the content of the program.

The continuous upgrading of LED display manufacturing technology has made many production teams and organizers have a special liking for the high-definition characteristics of the display, and it is easy to fall into the misunderstanding of "small losses and big losses" in the creative process. In order to reflect the characteristics of the high-definition picture as much as possible, producers are often keen to play a specially shot real video on the live video wall as the background stage. For example, in singing and dancing programs, a large number of urban landscape pictures and human life pictures are displayed. I wanted to use this to combine the artistic interpretation of the show with the authenticity of the pictures, but the result was counterproductive.

Stage performances pursue a high degree of formality, with color, light, formation, etc. as the length. Most of the videos shot in real scenes are too rich in color. They are used as the main background of the stage, but they will interpret the form of the stage program. It caused huge damage and made the audience feel "invisible" and "don’t know where to watch". The original design used to enhance the effect of the program had a huge impact on the audience’s ratings and violated the dance. The basic principles of design and program production services.

2. The abuse of LED display destroys the lighting effect of the stage performance area

The gradual reduction in the production and use costs of LED displays has led many creators to blindly pursue t

The concept of "panoramic video dance beauty". LED screens are widely used in dance design, and even all dance scenes are replaced by LEDs. However, many creators have overlooked the fact that LED screens can easily cause huge light pollution on the stage. When the stage is completed and the overall lighting is synthesized, it is regrettable.

In the overall design of the show, lighting plays a huge role. It can make the entire stage present a magical sense of space and layering, making the overall visual presentation more rich and interesting. In traditional stage dance design, the only light source is the lighting system. Directors, lighting engineers and dance artists can work together to create a unique stage space. However, when LEDs are used in large quantities, the situation has changed dramatically. In addition to the lighting system, the light sources in the stage space also include various self-luminous LED screens. In the process of playing various video materials, the changes of the LED display screen continuously change its own luminous intensity and color. This feature makes the stage lighting control more complicated and the lighting combination more challenging.



、3. Only the overall and partial LED screen usage habits make TV broadcast difficult.

Although many large-scale evening parties are held on the spot, most of them will request live TV broadcast.

The basic unit of a TV screen is shots of different scenes. To put it simply, it is panoramic, mid-range, close-up, and the performance of the scene takes into account the effect of "panorama". When designing and producing choreography, many creative teams often only consider the panoramic "big effect", but lack of consideration for the mid-range, especially close-up shots required for television broadcasts.

In traditional dance production, TV cameramen can find a background with low brightness or a background with large chromatic aberration in the background video as the background of the subject, and achieve a unique artistic effect on the TV screen, but it can be achieved on the LED screen. Wide range of applications. Nowadays, if the needs of the TV lens are not considered at the beginning of the design, the final picture will lack three-dimensionality, the main body of the picture and the background will easily match and overlap, and the TV transmission effect will be greatly reduced.

4. The lack of space in the design of film and television dance beauty restricts the visual extension of the performance venue

Compared with traditional dance techniques, the use of LED technology and video dance is the most important feature of the second space. Through various unique 3D technologies, the director can create a virtual visual space through the LED screen. The combination of this space and the real space on the stage can greatly broaden the visual space of the performance scene, give the audience a sense of time and space, and show an extremely rich stage visual effect.

But in fact, when most creative teams use LED screens, they still regard it as a traditional two-dimensional scene, rather than as a three-dimensional space. The visual effect of the final stage is not only to maximize the advantages of LEDs, but also to lose the characteristics of traditional LEDs.
