What is Virtual Studio and How to create them?

 The term virtual studio can refer to any number of technological tools that attempt to simulate a physical television and / or film studio. Such use of the term follows.

A virtual studio is a television studio or movie studio that allows real-time blending of people or other real objects and computer-generated environments and objects in a transparent manner.

An important point of a virtual studio is that the real camera can move in 3D space, while the virtual camera image is displayed in real time from the same perspective, so this virtual scene has to adapt to the configuration of the camera at any time. (zoom, pan, angle, scroll, etc.).

This is what distinguishes this new technique, called Virtual Production, from the traditional chromakey technique. A virtual studio does not require post-production since it is in real time.

Virtual production uses emerging Extended Reality (XR) technologies.

Using XR, film crews project virtual 3D environments onto giant LED screens in semi-circular ‘Volumes’. Virtual production requires a 3D graphic artist and 3D computer graphics software and also virtual set software is required to create the virtual background and all the images that appear in front.

There are many technical solutions for creating virtual studios, but most include the following components:

• Camera tracking, which uses optical or mechanical measurements to create a live data stream that describes the exact perspective of the camera.
• Real-time rendering software, which uses camera tracking data and generates a synthetic image of a television studio.
• A video mixer, which combines the video from the camera with the video from the rendering software in real time to produce a final video output. One of the most common ways to mix video to replace a chroma key background
