1.What Is Extended Reality (XR)?

XR stands for Extended Reality, a term that is a technology that combines virtual and real environments, whereas “X” stands for unknown future technology.

XR is a rapidly evolving technology with film, broadcast, live entertainment production applications, and more.

XR technology covers Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR).

  • VR (Virtual Reality): The combination of virtual and display, VR is a computer simulation system that can create and experience virtual worlds, creating a perfectly immersive 100% virtual world through sensor input. The multi-sensory and interactive nature of VR technology makes it popular with many.
  • AR (Augmented Reality): AR technology can subtly integrate virtual information and the real world to complement each other, thus realizing the “augmentation” of the real world. Virtual images take reality as the main body and are superimposed on each other. It uses multimedia, three-dimensional modeling, real-time tracking, intelligent interaction, and other technical means.
  • MR (Mixed Reality): This technology presents an information loop of interactive feedback between the real world, the virtual world, and the user, helping to enhance the realism of the user experience, Simply put, MR is a new visual environment combining the real and virtual worlds.

2. What Is The Application Of Extended Reality?

The field of XR application is very wide, especially the display category.

From the perspective of LED display, the main application of XR is in these 2 aspects:

  • LEDs in film and broadcast

The production of virtual space requires LED displays and floor LED screens to build an ideal space; dynamic and advanced scenes can be displayed through LED displays, which are very helpful for virtual production, shooting, and broadcasting.

  • Virtual production and XR stage

The XR stage can replace the green screen when live streaming, allowing presenters and crowds to see the live interactive scene around them so much fun that event organizers want to take advantage of the new technology to make their business easy and happy.

bibiled is an advanced manufacturer for most organizations participating in this fast-growing innovation to meet high expectations.

3. What Is An XR Stage?

XR stage is one of the led wall applications for virtual production; virtual production refers to space and studio with a complete workflow including LED screens, media servers, camera tracking systems, spatial positioning systems, and real-time rendering systems to provide immersion stylized, extended reality environments to accommodate live productions.

4. How Does The XR Stage Work?

In XR production, a pre-configured 3D virtual environment generated by a graphics engine is displayed on one (or more) high-quality LED screens that form the backdrop for live-action, real-world events.

When combined with a precision motion tracking system, the camera can move in and around the virtual environment, with real and virtual elements seamlessly blending to create the illusion of composition.

5. Benefits Of XR Stage

  • Immersive and editable in real time

 The XR stage, combined with a real-time engine, camera tracking, LED display, and virtual scene expansion immerses talent and performers in a 3D virtual environment, graphics can be rendered and displayed on the virtual production LED wall, and you can quickly view the video content.

Editing in real-time, and allowing content to appear around the performer at the same time, will go a long way toward reducing post-production time and budget.

  • Faster camera calibration

The XR platform can calibrate the camera tracking system faster than a traditional green screen; It greatly improves the efficiency of setting up scenes across different sessions.

  • Natural lighting

The lighting for the film was generated by the virtual production LED wall itself on the XR stage, helping real-world elements blend into the virtual environment without spending time and budget to set up additional lighting systems; this helps save time and reduce the budget, no chroma key synthesis, more realistic, the traditional chroma key technology has the disadvantages of unrealistic image rendering, post-production, and high personnel costs.

The XR stage perfectly solves these problems.

  • Cost savings and safety

With the XR Stage, all scenes can be created without traveling to multiple locations or trying to find locations.

In the age of social distancing and covid-19, virtual environments can keep cast and crew safe in a controlled environment, with fewer people on set and easier social distancing and covid testing of employees.

6. The 6 Best Times To Use An XR LED Stage

  • Time limit

One of the best times to use an XR LED stage is when your production processing time is limited.

Say you need to shoot specific scenes like sunsets and sunrises in half a day, which can be challenging because not only do you have to take into account the weather, but you also have to take into account that there is a big difference in light between mornings and afternoons, and it’s hard to achieve ideal specific scene, studio shooting of the XR LED stage not only helps address time constraints but also reduces the time it takes to get the perfect lighting. LED walls in virtual production give you accurate ambient lighting and reflections.

  • Multiple different locations

Another great time to use an XR LED stage is when you have to shoot in many different locations in a short period.

Use LED walls to display virtual backgrounds; you can easily change a variety of realistic virtual backgrounds at any time; for example, your team can choose to shoot in the Amazon rainforest in the morning and the summit of Mount Everest in the evening. This reduces the cost of shooting on set and eliminates the inconvenience of unpredictable weather conditions.

  • Hazardous and computer-generated locations

The best time to use an XR LED stage is when shooting in a dangerous location.

Some shooting projects require the production team to shoot in dangerous and extreme locations such as volcanoes, canyons, deserts, and virgin forests; for safety precautions, more security personnel need to be hired, resulting in a substantial increase in costs and insurance premiums.

  • Creative freedom

The best time to use an XR LED stage is when a director or creative team wants more creative freedom to achieve the most desirable results.

Your creative team can now use props and costumes of any color in the scene; plus, when the background is computer-generated and rendered life, the director can ask for creative changes or fine-tuning on set at any time. For example, the director feels that the virtual volcano in the background is too high, so he can ask the designer to adjust the height of the volcano on the spot at any time, and the changes can be quickly reflected on the LED wall. 

  • Immersive live events

The best time to use an XR LED stage is when you need to broadcast an immersive live event with real-time foreground graphics and virtual backgrounds.

During the shooting process, the live host may stand on a stage with an LED background, focusing on sitting in front of the TV or computer as “host + virtual screen” for example, the host may be standing on the top of the mountain or somewhere in space to broadcast live.

  • Save post-production cost and time.

Finally, one of the most important reasons most filmmakers are looking into XR LED stage production is because it helps save post-production costs and time.

The sound of “post-fix” is often heard at the shooting location, especially for those special effects-intensive films, and virtual production with XR LEDs can help eliminate the time-consuming task of post-fix.

7. Virtual LED Display VS. Green Screen: Which Is Better For XR Extended Reality?

Green screens used to be a must for film production and events; however, virtual LED displays have revolutionized virtual production and XR extended reality, so if the dilemma of virtual LED displays and green screens has been bothering you. If you don’t know how this applies to XR Extended Reality, read on to find out more.

What are virtual LED displays and green screens?

1. Virtual LED Display

The virtual LED display is a 3D technology innovation; it can help create a variety of themes you want by rendering with a real-time 3D engine to achieve a virtual scene where real people and fictional scenes are fully integrated, so what you shoot is what you get.

2. Green screen

The green screen technique is chroma keying, which involves a plain wall as a background, with an active object or objects placed in front of the screen. During the post-production stage, solid colors are replaced with the desired background, a technique that has been around for years in the games and media industries.

The similarities and differences between virtual LED display and green screen

1. Resemblance

The green screen and the virtual LED display can be used as a background for shooting, and the frame can zoom in and out.

2. The difference

1) The difference in total cost:

Generally speaking, the price of purchasing a high-resolution LED display is much higher than that of a green screen.

But in the long run, LED displays are more versatile and cheaper than green screens. 

Why?

The post-production of green screens requires more capital and human input than LED displays, and every event needs to consider this factor, and green screen production is not cheap.

Virtual production can effectively reduce crew transportation costs and environmental waiting costs for location shooting.

2) The difference between post-editing and in-production editing:

 Green screen photography has a long history and played an important role before LED screens became popular in film and television shooting. 

The green cloth shooting focuses on post-processing, and the actors usually perform imaginatively in front of a green/blue screen. After computer post-processing, the director can see the final picture after combining performance and special effects.

The shooting method with the LED screen as the background has real-time characteristics.

You can see the following cameras when the set moves, achieve accurate and realistic visual tracking and edit the content being played on the monitor in real-time. XR shooting allows the director to directly experience the real-time picture on the spot, shortening the workflow and greatly reducing post-production. Production workload.

3) Shoot the difference in the production process

-Traditional Green Screen Shooting:

  • Place the physical background and build the green screen background
  • Capture video content
  • Perform video post-processing, including background content, modeling
  • Complete production

– LED Display Background Shot:

  • Build LED display studio.
  • Shoot video content, XR real-time synchronous rendering
  • Complete production

Advantages of using virtual LED displays compared to green screens in XR Extended Reality

1. real-time display

In the past, film production was done with pre-shooting before a green screen, followed by post-production and special effects editing. Still, with LED screens, virtual productions fully allow real people to merge with fictional scenes for real-time display and editing.

2. Improve creativity

The virtual production of virtual LED displays can liberate film and television creators; actors no longer need to rely on imagination to perform, and directors can truly create freely.

3. The innovative, creative process

The virtual part of the creation does not need to be separated from the actual shooting, and the producer can see the final footage and content in real-time. The LED screen also breaks the space limitation, and the producer does not need to search for suitable shooting locations worldwide.

8. How To Build A Video LED Wall, XR Stage, And Virtual Production (Types of XR LED wall)

XR LED Walls can be customized to meet your unique requirements according to your installation and setup; we commonly have curved LED walls, corner LED walls, and creative LED screens.

9. Workflow Of XR Virtual Production

The LED wall is the heart of the XR stage.

LED walls help ensure excellent image quality with a wider color range and high brightness.

Other important components include camera tracking systems, controllers, graphics engines, render servers, and virtual production pipelines.

10. Virtual Production XR Stage Case Study  

1) Launched in January 2021, MADO Xr’s RPG studio in Paris is one of the largest XR studios in France, located in the 800-square-meter film studio in Epinay.

 

2) Located in Old Dairy Court near Central London, UK, milk it XR Labs is a small permanent XR studio that works closely with all popular XR workflows (Unreal, Notch, and Unity) with BBC ITV.

 

3) White Light’s SmartStage in Mermaid, London, UK, is designed for the ‘new normal’ workflow; White Light’s SmartStage hosts the UK & Ireland Lions 2021 Tour announcement, BBC’s ‘Famous’ transmission pilot, and Fusion Comms’ BDO Rethink Festival, a global virtual conference attended by more than 2,500 delegates.

 

4) SmartStudioXR at the Royal Lancaster Hotel in London, UK, provides a unique backdrop for corporate clients, featuring a large event space with LED backdrops, floors, and XR equipment.

11. What Technical Points Should We Be Careful About The LED Screen For The XR Stage?

  • Color correction

The LED display screen must ensure true color fidelity, and the color temperature value must be between 6300K and 6500K.

  • High brightness, imitating real light source.

If you directly simulate the light source in the real world with high brightness, you can save the workload of lighting, and you don’t need to spend a long time in post-production to complete the work.

  • High-quality display performance

High-quality visual performance is the foundation, so it is very important to choose stable internal electronic accessories, such as China’s more reliable brands, Guoxing’s lamp beads, Mingwei’s power supply, etc.

  • Ripple effect

The moiré effect is related to pixel pitch, which is a very tricky problem for LED virtual production, and we have some solutions to deal with it, such as temporarily using the green screen as the background.

The most reliable way is to find a professional photographer to solve this problem according to the specific situation of the scene, such as finding the right distance between the lens and the screen.

  • Blink

The most targeted solution is to find a high-quality LED display that flickers less, and photographers can set the shutter speed to 1/60th of a second since normal LED screens typically run at 60Hz.

12. How Much Does An XR Stage LED Screen Cost?

The cost of an XR stage screen or virtual production LED wall system depends on the space or size of the LED screen used for the XR stage, video processor, and hanging/stacking system.

With so many decisions affecting the final cost, it’s important to understand them before choosing these systems.

  • Screen size: 2 sides, left/right, 7m x 5m, 2 units, 70 square meters
  • Screen price, Matrix 2.6mm, 70 square meters, $150,000
  • Processor, Tessera S4/S8, 4 sets, USD1.4k – 3k
  • Hanging/Stacking System: USD2k/USD12k

13. History Of XR Virtual LED

As we said in the first chapter earlier, XR technology includes augmented reality (AR), virtual reality (VR), and mixed reality (MR), a series of immersive technologies dating back to the 1800s.

This chapter briefly describes the key milestones in the development of XR:

1)  The 1800s:

  •  In 1838, scientist Sir Charles Wheatstone outlined the concept of “stereoscopic vision” or “binocular vision” – the brain combines two images (one for each eye) into a 3D image, facilitating the first development of a stereoscope, a device that takes a pair of images and turns them into a 3D image with the illusion of depth, similar to how today’s VR systems use stereoscopic displays.
  • The 1900s: In 1935, Pygmalion’s Spectacles was published by the then-American science fiction writer Stanley Weinbaum, in which the protagonist explores a fictional world with a pair of goggles, which is the first prediction of VR as we know it today.

2) The 1950s to 1970s

  • In the ’50s, ’60s, and ’70s, we saw early VR and some practical examples of AR technology.
  • In 1956, cinematographer Morton Heilig created the first VR machine, Sensorama, a film that combined 3D color video (stereoscopic technology) with audio, scents, and a vibrating chair to immerse the audience in the film.
  • In 1960, Heilig went on to patent the first head-mounted display – combining stereoscopic 3D imagery with stereophonic sound.
  • In 1960, based on Heilig’s creative idea, Philco engineers created the first VR headset with motion tracking technology designed for military use in 1961.
  • In 1968, Harvard professor Ivan Sutherland created the first AR headset, becoming an early pioneer of today’s AR experiences.
  • In 1970, MIT created the Aspen Cinematic Map to show for the first time how VR could transport users to another place entirely.

3) From the 1980s to the 2000s

  • In 1980, the VR experience technology was enhanced.
  • In 1985, VPL Research Inc was the first company to sell VR goggles and gloves.
  • In 1987, the term “virtual reality” was coined.
  • In the early 1990s, ordinary households began to buy VR headsets, while AR was mainly used for live games and other sports broadcasts.

4) 2010 to 2020

Many people in the early 2000s did not well understand XR technology, but starting in 2010, XR technology started to gain momentum:

  • In 2010, 18-year-old Palmer Luckey prototyped the Oculus Rift VR headset, a revolutionary headset that reignited interest in VR with its 90-degree field of view and computer processing power.
  • In 2014, Sony and Samsung announced they were developing their own VR headsets.
  • In 2016, hundreds of companies were developing VR and AR experiences, and it was also the year that Pokémon GO games brought AR into the mainstream.
  • VR, AR, and MR rapidly expand across various industries.

Today, XR technology is being adopted in various fields from manufacturing, education, healthcare, construction, and even law enforcement.
