The most common weather forecast is the most typical case of virtual studio.
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 fifty cents special effects, some necessary preparations should be made before shooting.
For example, in order to facilitate matting, it is necessary to clearly distinguish the foreground (needed part) and background (unnecessary part) photographed by the camera. Because there are no humans with blue skin and green skin in the range that our eyes can see, we use a blue screen or a green screen (high-level users will use a blue frame or a green frame) as the background, and make the blue or green transparent through technical means, so that we can get a clean prospect and greatly improve the efficiency of matting. So the foreground should avoid blue or green, otherwise it will be cut out with the background.
In other words, it is almost impossible to broadcast live with goods in a virtual studio, except for the clothes and accessories of the anchor, and even all products and packaging can't be blue or green.
