VP using LED-wall is a trendy technological approach to solving artistic tasks in the preparation and production of video content. The essence of the technology is the combination of a virtual 3D scene and real objects in the frame.

Tracking of a physical camera in a virtual environment creates a parallax effect. Thus, viewers get a feeling of presence in the location, rather than an "image on the background of something". The whole system runs on the Unreal Engine game engine.
