XR is one of the trendiest and most recent flavours of Virtual Reality, especially when combined with LED video walls.
Conjuntos virtuais e realidade aumentada (AR) já existem há décadas, e o conceito de realidade virtual se diversificou com a chegada de novas tecnologias de exibição, como paredes de vídeo LED, que fornecem alternativas ao Chroma Keying tradicional.Produções recentes aproveitaram essa tecnologia e as emissoras estão cada vez mais usando para shows ao vivo, mas muitos usuários ainda veem o XR como um conceito difuso associado às paredes de vídeo. So, what is XR?
As a form of Virtual Reality (VR), Extended Reality (XR) can be defined as the combination of real and virtual environments.Se incluirmos o consumo interativo de conteúdo na equação, devemos adicionar quaisquer interações humanas-máquina geradas pela tecnologia de computadores e vestíveis, mas seguiremos a produção típica de transmissão e conteúdo de filmes para tornar as coisas mais simples no momento.
However, in practical terms for broadcast and film content creation, XR is normally understood as the combination of virtual environments projected in a LED wall, and sometimes LED floors, with real characters on stage, sometimes including other graphic elements in a sort of Immersive Mixed Reality (IMR).
Ao usar LEDs como fundo/piso, a câmera captura a imagem combinada da renderização de fundo e os personagens. However, there is no technical reason why the LEDs can’t be replaced by a Chroma set so, using one method or the other is key for achieving a given result.
There are many applications for LED-based XR production which outperform chroma set production, starting with live virtual sets displayed in the LED walls so not only the audience at home can see it, but also the live audience on a physical show or event can see it.
Also, excluding the need for green sets or chroma keying can be quite interesting for film and drama productions when virtual environments are required rather than physical scenarios and props. On top of that, we can add in-screen Augmented Reality (AR) content that can be shown live, rather than using real-time renders and combine the scene on a separate screen.
But this technology is not a response to any possible VR requirement, as it shows several disadvantages compared to traditional chroma keying.Problemas com foco, moiré, atrasos e muitos outros devem ser considerados antes de decidir qual método (LEDs ou Chroma Keying) é melhor para nossa produção virtual.
That is why, being at the forefront of virtual technology for the last 30 years both with chroma and LED/projection environments, Brainstorm has produced the comprehensive White Paper Brainstorm Guide to Understanding XR, which aims to clarify concepts about XR technology, its applications, workflows, advantages, and disadvantages.
