Big Led Screen for Virtual Productions

The continuous growth of technological development made an exponential leap in recent times and this is evident in the amount of audiovisual productions that were updated thanks

to new equipment, methods and techniques offered by the current market. The led video wall

screens were first used in the film industry just a couple of years ago in a television production that has already become a mythical series for lovers of the Star Wars Saga and although other projects have already adopted this technique, its use promises to expand beyond the

science fiction cinema.

In the United States, 90% of productions with special effects now

are made with Giant Screens

Due to its large number of benefits when filming and editing a movie, the vast majority of

audiovisual projects that have great challenges when it comes to special effects

opt for the Stagecraft, the giant led screens that set the plot at the end of the stage

instead of the already known old chroma.

This innovative recording technology is a distant relative of the cinematographic technique from the 30s called rear projection and it came to unseat the green or blue fabric.

The big problem is that on that static element that is the chroma, the

animation, meaning that the actors have to imagine the environment when recreating a

scene and on a technical level the art team has to create, in the post-production stage, the

scenarios where they were developed. With led video wall this becomes extremely

dynamic as live images can be played back.

Mandalorian is a successful experience of using this technology

Beyond the fact that the use of giant led screens is very common both in events, in houses of worship, in corporate meetings and social events, in industry

of cinema gained greater notoriety from its use in the Mandalorian series, which produced

Disney + and premiered on the same platform in November 2019. This space-western that

takes place in the Star Wars universe is the success story cited when talking about this technology.

Due to its ability to reproduce images with astonishing clarity and adapt to each shoot,

this technique which uses giant led screens to create the wonderful special effects and the

setting of each shot, gave the blockbuster a level of realism unimagined in

an industry accustomed to chroma.

With three giant led screens – one of them located on the ceiling – with impressive dimensions

6 meters high by 23 wide, and slightly curved, they managed to create a frame where

project the animation simultaneously while the actors recreated the scene.

What are the characteristics of these LED Video Walls for virtual productions?

Once understood that the main difference is that for the chroma the image is added through

a computer at a time after recording, while led screens create the

image by light simultaneously while recording, it can be said that the characteristics

about the use of video wall LEDs versus chroma LEDs have no point of comparison.

Some of its great benefits for LED Video Walls for virtual productions could be summarized in the following items:

  • Great help for the actors when playing the assigned role: with the chroma, the

actor did not have a total notion of what would happen next in that static cloth of color,

but with the stagecraft technique the artist can see and be in the environment at the time of

get into the role which gives realism to the performance.

  • Coordination of teams and unification of studies: cameras and screens are

synchronize, that is to say that when the camera moves the stage will also do it, which

it also allows you to use only one recording studio for the entire film.

  • There is no problem with edges: in chroma, as it does not have well-defined edges, it is

It is important that the actors stay within certain limits so as not to damage the

scenes, while with LED screens this problem disappears.

  • The costume color is enlarged: since the chroma uses green or blue in its fabric, they must be

avoid those shades for the wardrobe as it causes technical inconveniences. With the new

technology, this was no longer a limitation.

  • Visualization of the final result: now at the end of each shot you can check the

result and correct errors, before it was impossible since the result was seen in one of the

final stages of the project.
