In the past, when the production of film and television industry encounters difficult to realize the scene, usually through the green screen shooting to complete, but the green screen shooting is more restrictive, in recent years, there is a new shooting trend, with LED virtual studio to assist the shooting.
LED virtual studio not only can generate any scene in real time, but also the picture is real and reliable, with multiple advantages, traditional green screen shooting is gradually replaced.
What is LED virtual studio?
A venue that uses the digital world created by LED displays to assist real-world people or objects in filming and producing movie and TV content is called an LED virtual studio.
LED virtual studio is different from traditional green screen filming, which requires the addition of the desired images in post-processing. In addition to the cost of the traditional green screen shooting, the production method is also more complicated and difficult, while LED virtual studio can play the demanded images as background in real time during the shooting, not only the LED screen display effect is excellent, but also saves the time and money cost of film and television creation, so LED virtual studio is very popular in the industry.
Key components of LED virtual studio
LED display
The most important component of LED virtual studio is the LED display, which is directly related to the presentation effect of the subsequent shooting images, an excellent and high-performance LED display can provide more realistic and vivid images for LED virtual studio, and improve the quality and realism of video production.
Rendering engine
The powerful rendering engine enables the LED virtual studio to adjust and render the picture in real time when shooting video, sometimes the original picture needs to be replaced when shooting on site, the rendering engine can make and render the scene video on site and put it on the LED display, avoiding the delay in the shooting progress, and reducing the cost of the secondary modification in the later stage.
Camera tracking system
During the shooting process, the real world people or objects are constantly moving, similarly, the shooting camera also needs to constantly change the angle, in this case, in order to ensure the realism of the shooting picture, the virtual environment displayed on the LED screen and the camera’s perspective need to be kept aligned.
Therefore, LED virtual studio needs to have a camera tracking system to track the moving camera in real time, according to the camera’s position changes to adjust the screen, to ensure that the perspective between the two to maintain the ideal state.
Virtual Production Server
The virtual production server integrates the LED control system, content rendering engine, camera tracking system, and other devices or software connections, which are needed to transmit the camera capture screen, virtual content screen, and camera tracking system signals to the LED display, and to transmit the synthesized video to the director’s desk for viewing and storage.
Lighting system
video shooting for the light source requirements are relatively high, the LED display light source can only ensure that the virtual world is well lit, for the real world of the protagonist of the shooting, relying only on natural light sources is not enough to support the shooting.
Need to use artificial lighting equipment to make up the light of the real scene, so that the real world and the virtual world light source coordination, reasonable lighting for film and television video to create a relevant emotional atmosphere.
What are the requirements of LED virtual studio on the specification of LED display?
Ordinary LED display screen only need to provide only for the human eye to watch, LED virtual studio picture quality in addition to realistic and delicate, but also to resist the camera shooting, many of the naked eye to watch the screen may not meet the requirements of the shooting, filming of the LED display for the color reproduction, refresh rate, contrast, and viewing angle and other basic conditions are very high requirements.
Inhibit Moire
Moire is the use of video cameras to shoot the LED screen in the camera sensor to form high-frequency interference in the color stripes, which is most of the LED screen facing the camera will produce the situation.
By designing special lenses for LED screens and adjusting the depth of field and aperture of the camera when shooting, moire can be effectively avoided when recording.
Low Reflection
The higher the light reflection of the LED screen, the greater the impact on the LED screen image recorded to the camera.
By adding a light-absorbing slot design to LED virtual studio’s LED display, and using a frosted matte process for the LED screen, you can reduce the light reflectivity, lower the impact of light reflection during recording, and make the recording screen clearer and more natural.
Wide color gamut and high color rendering index
wider color gamut signifies that the LED display can present more colors, the maximum degree of color reproduction, high color rendering index makes the LED display screen more vivid and bright, the picture into the mirror more beautiful.
Wide viewing angle, no color deviation
In the process of filming, the main character or subject of the shooting will move, the camera needs to keep changing the shooting angle for filming, so the LED screen needs to have a wide viewing angle, to ensure that even in a variety of different angles of filming, the LED screen image will not produce color deviation.
High refresh rate
When the refresh rate of the LED screen is not high enough, black horizontal or vertical lines will appear on the screen when the camera is used to shoot the LED screen.
Therefore, LED virtual studio LED screens need to have a high refresh rate in order to avoid black streaks on the camera screen, which can affect the video production.
At present, the LED virtual studio LED display refresh rate can reach 7680HZ, which represents the LED display industry’s top refresh rate, in the camera shooting, 7680 HZ LED display screen is clear, image stability, perfect to meet the shooting requirements.
Advantages of LED virtual studio
