What is the screen behind Luo Yonghao’s live broadcast?

1. It will definitely not be a virtual studio, and no keying technology is used.

2. Someone exposed Mr. Luo’s studio on Weibo (the previous respondent had already posted a picture). Judging from the brightness, it should be an LED screen.

Why doesn’t Luo Yonghao’s live broadcast room use a virtual studio?

From the current stage, virtual studio has its own limitations and is not suitable for live broadcast delivery scenarios.

The most common "weather forecast" is the most typical virtual Studio case.

To put it bluntly, virtual studio technology uses keying technology to achieve the purpose of changing the background. In order to make the finished product look less like 50-cent special effects, some necessary preparations must be made before shooting.

For example, in order to facilitate keying, it is necessary to clearly distinguish the foreground (required part) and the background (unnecessary part) captured by the camera, because there are no blue or green skin as far as we can see. Human skin, so use a blue screen or green screen (more advanced ones will use a blue box or a green box) as the background, and use technical means to turn the blue or green into transparent, you can get a clean foreground, making the keying extremely efficient. Big improvement. Therefore, the foreground should avoid blue or green, otherwise it will be cut out together with the background.

In other words, if you use a virtual studio to carry out live broadcasts, except for the host's clothes and accessories, even all products and packaging cannot be blue or green. This is almost impossible.
