A future glimpse: How will LED wall green screen help with virtual production?
LED walls and green screens are often used as video background displays at corporate events, parties, and concerts. But they can be much more than that! Learn how to use LED wall technology to create your own green screen and produce videos with high-quality effects right in your living room! Find out more in this advanced application of LED wall technology article!
The LED wall is a digital display technology that uses an array of light-emitting diodes (LEDs) to produce images. The most common form is a video display, but other applications include signage, advertising, general lighting, and architectural lighting. An LED screen can be made from one or more modules connected together by wire or optical fiber cables. Modules are usually square or rectangular in shape, but may also be irregularly shaped for special effects. In any case, each module consists of hundreds or thousands of LEDs mounted behind a panel of glass. Each pixel on an LED screen can turn on or off individually to produce any color in the spectrum. The number of pixels per unit area determines resolution, which is measured in pixels per inch (PPI). Common resolutions include 800×600, 1024×768, and 1280×720. A single high-definition television set contains 1 million or more pixels; it's not uncommon for large LED screens to contain several million pixels
A lot of people use green screens for creating a virtual environment, in fact, it has become a must for most projects. A green screen can hide all technical equipment behind a subject and help achieve a better visual effect. Here are the pros of using the LED wall as a green screen for virtual production.
The first benefit is that it has a more realistic reflection than a traditional green screen. A lot of people use a green screen to create a virtual environment, but it has a problem that there is no realistic reflection. For example, when we use the green screen to shoot a product video, we usually put a white board behind the product and then add blue background in post-production. However, because the white board does not have any texture or color, so it will look like we just put the product on a blank background. This kind of effect is very unnatural. But with an LED wall as a green screen, you can get real reflections from your subject which makes your footage much more professional. So if you want to make a high-quality product video, you should consider using the LED wall as a green screen for better visual effects.
You can capture awesome outdoor lighting with an LED wall. When you shoot with a green screen, it will take time to adjust the lighting. But with an LED wall, you don't need to worry about that. Because it has a lot of built-in colors and white balance settings, so you can easily get perfect light in one shot. So if you want to save your time on-set, then you should consider using the LED wall as a green screen for virtual production.
Another benefit is that it's suitable for all seasons. Some people like to shoot outdoor scenes in winter, some others shoot indoor scenes in summer. But no matter what season you are shooting, there is always a time to adjust the lighting. For example, if you use a green screen in winter and then add blue background in post-production, it will look bad because the blue background looks more vivid than the normal environment.
Another advantage is that it can work as a real monitor. Most monitors are calibrated, which means it doesn't look like a normal monitor, and then some color effect will be added in post-production to make your footage looks more realistic. However, with an LED wall as a green screen, you can get a real screen directly which will save you post-production time and cost.
One challenge is that it is a little bit expensive. Compared to the traditional green screen, it has more advantages, but it also has a higher price. It's really up to you if you want to use it or not. If you have enough budget, then I highly recommend using the LED wall as a green screen for virtual production because it will save your time and cost in post-production.
Another challenge is that camera might pick up moiré. Moiré is a pattern that appears when two grids are overlapped, and it's very hard to remove in post-production. So if you want to use the LED wall as a green screen for virtual production, then you should choose a camera with high resolution. And if you have a 4K camera, then there will be no problem at all. So make sure your camera can handle it before using it as a green screen for virtual production.
Some people don't like the LED wall because they think it looks too visual. And that's why it doesn't have enough contrast and color reproduction, which means you need to adjust some parameters in post-production. The most common problem is chromatic aberration, which comes from a lens or light source. Because of chromatic aberration, some color is missing in one pixel.
Another challenge is dropped or doubled frames. If you have enough budget and skills, then you can use chromakey software to fix it. However, if your equipment is not high-end, then it's very hard to fix in post-production. This problem won't happen on a green screen but will occur on the LED wall as a green screen for virtual production.
The price of a green screen is around $1,300 depending on its size. In addition to that, you will need screen material and other accessories.
LED wall green screen will be used in many ways to create a new kinds of visual effects. In addition to using it for the virtual set, it will be used for virtual cameras and virtual actors. Besides, all these applications will help with an emerging technology called mixed reality (MR). Mixed reality is a combination of the real world and the virtual world where you can interact with both worlds at once. For example, if you are playing an MR game like Pokémon Go then you can see real-world objects as well as virtual objects at the same time on your phone's screen. In short, the future use of LED wall green screens is limitless.
In conclusion, the LED wall green screen is a great way to create an amazing visual experience for your audience. It can be used in a variety of applications and settings, as well as a way to save money on production costs. While it may not be quite as high-tech or effective as other methods, such as chromakey, it's definitely worth considering if you want to save some cash!
