- In this video we take a look at how to build sets for LED wall virtual production. We are just starting out in virtual production and experimenting with the the best techniques to create realistic & cinematic scenes against our 6.5 x 2.75m LED wall. In this episode we build a phone booth and shoot out a quick scene in the snow. If you're a filmmaker or are interested in virtual production, set building and lighting techniques, this one's for you.

The concrete application of virtual background lighting blending with a physical set is the key. That is the key!!!!!!
Sir, you are exactly where I want to be someday, thank you for sharing this information
agreed. ive done a few ICVFX jobs , exactly as u say .. these things make a difference plus a few more things, like low latency tracking lighting, brightness contrast . color balance of foreground and video wall. etc.
really good LED wall setup, our studio are also experienced with LED walls few a few years now, recently we've been planning to install Mo-sys startracker so we can animate the background with the camera motion. hopefully with light setup we can achieve great result.
Super exciting! Would love to see more of "the Wall"!
Going down a stop or 2 on the LED could help match the shadow of the face more, the blowout gives it away
Looks really great guys! I've been itching to get a crack at VP myself. Cant wait to see what else you come up with.
Great video mate
Very nice work!
Hey gang. Have you tried your setup with a game engine yet? With some simple tracking you could mitigate that 2D look (although you probably already know this). I have a few bespoke locations you could try if you like?
Yes we have! It works surprisingly well from our very basic tests but none of us are Unreal artists, so it can be pretty daunting at times.
What’s the LED specs, pixel pitch? And how far did you place the subject from the LED?
How do you calibrate the colour output of the video wall? Or match lighting to it, for white balance etc
To start with we've used an X-Rite Profiler to do a rough calibration and then we run a lot of the material live through Davinci Resolve Studio to allow us to tweak settings in real time.
Groovey! What are the specs of your LED wall? Cheers
Off the top of my head I believe we are close to scope aspect ratio with around 2500x1080 pixels and approx 800-1000nits. We change the Hz / refresh rates depending on the project so I'm not sure which we use more at this stage.
The background only works because its way out of focus and obscured due to the water.
That is the reason you did it not to show off anything else. A green screen is better in most applications on small scale and its way more affordable.
There are cheaper methods to get good quality as well.
There are great ways to get good results with cheaper methods, like green screens, and we do actually frequently use them - sometimes even in combination with the LED wall.
It's worth noting that this scene took us approximately 20min to film on a Friday afternoon with practically no crew and was all completed in camera with basic stock footage playing on the LED wall and just a simple snow effect added in post.
We have shot simple and more complicated scenes with the LED wall less obscured and have found that for many shoots it makes production a lot easier and significantly quicker to produce than traditional green screen, but green screen still has practical uses for certain shots, just like an LED screen makes a lot more sense for other types of shots.
Okay bro…
