Keep under 4mm pixel pitch LED for virtual production

Keep under 4mm pixel pitch LED for virtual production

What if you’re a couple of guys in a LAB on a Friday and all you have is a 2m x 4m, 4mm (3.9) pixel pitch LED wall that you’ve been loaned by your mates at 80Six, looking at it, what could we get away with shooting on it?

That was this weeks OSF Friday Lab challenge. Usually, this particular panel is only used in our development studio for system testing, not for shooting. But what does an almost 4mm pixel pitch screen actually look like up close and personal; in a real cinema camera. It’s not bad, it’s not great either but if you take a look, it may be good enough for what you want to shoot.

As expected, Trying to not see the LED pixels in the camera, at this huge pitch size, is crazy hard, forget focussing anywhere within 4m of your LED, not gonna-happen you’ll see pixels in your final image, instead we had to position the talent at least 4m away from the screen, supporting the basic rule of thumb of having your talent 1mm = 1m from the LED (approx).

We then went wide open on the iris of our old RED zoom (2.9), we then hit max on the LED processors nits (to try and get as much light between the spaced out LED pixels as possible) but, then we had to ND filter up to counter the maxed out LED. Even then we struggled, a 2.9 could really do with being a 1.9.

Also if you ever need to use such a big pixel pitch as this for real, you are going to need a big shooting stage. What you see here was a total battle with focus points and the amount of stage area you would use with such a high pixel pitch LED (would be a potential 8m of wall clearance, if shooting reverse or in the round).

This means you need a lot more space when your shooting with higher pitch LED panels, as you need space to keep your DOF away from bringing the pixels sharp. All in all a good days shooting and we are happy with the results given the minimum crew, with no post,  all shot and edited in a day, it still amazes us how efficient virtual production is at filming content at speed.

To sum up we’ll be sticking with panels with a pixel pitch of between 1.9 to 2.8 on-set, but this was an interesting little Friday project to see what we could cook up with what we had to hand. I think we may knock a few more of these out over the coming weeks, it was great to actually shoot something on our studio.

GODBOX Ranked Most Powerful Virtual Production Computer

GODBOX Ranked Most Powerful Virtual Production Computer

The OSF GODBOX ranked the 18th fastest computer in its class (out of 500,000 benchmarked builds) powering real-time VFX and LED stage virtual productions. The newly released GODBOX Pro MKII is the first OSF computer to ship to studios with the new proprietary OSFX architecture, OSF’s answer to optimised on-set computing with direct to display technology.

Power each 4K LED Canvas with GODBOX™ Pro MKII

With direct support for Unreal Engine, Unity 3D and Omniverse. The new build also marks On-Set Facilities move away from Intel’s i9 to AMD Threadripper along with an upgrade from the NVIDIA Quadro RTX8000 to the latest NVIDIA A6000 GPU. Full system spec.

Before we go any further we would like to thank the teams at iMAG Displays and Treehouse Digital for inviting us to come down to their LED stages to test the power of the new GODBOX™ in action. Also a huge thanks to Brompton, RED Digital Cinema and Ncam for supporting these tests. May we also just clarify our ranking methods. We use multiple rendering benchmarking tests ranking the GODBOX™ against a worldwide sample of hundreds of thousands computer builds. Benchmarking is vital, but at OSF we believe the only real way to test our new products is on-set.

Testing the GODBOX Pro MKII On-Set

It was a fantastic opportunity to show the full power of our latest GODBOX Pro on the big stage. On the day, the OSF virtual production computer powered both the camera tracking and 3D UE4 virtual environments simultaneously to 2 x 4k LED canvases. Driving low-latency, HDR real-time rendered graphics to a 32m x 3m, 2.8mm pitch volume, powered by a total of just 2 synchronized GODBOX Pro computers. 

Proving our latest GODBOX Pro build on-set, capable of pixel perfect mapping, delivering low latency 4K outputs at 120fps to each 4K LED canvas, we benchmarked the system and found at 4K we still had a whopping 80% of computing headroom left for artists to utilise in engine for real-time sets and VFX.

In the first GODBOX™ the i9 was chosen for it’s stability at lower cores, but with the latest advances in the OSFX architecture, OSF reports production ready stability has now been reached on all 32 cores and 64 threads powering 8K UHD HDR output from all major engines.

Driving the iMag’s Black Pearl and Black Diamond ROE LED panel walls, the OSF engineered virtual production system delivered blisteringly fast and reliable 10bit, HDR, ACES pipeline, real-time raytracing support. With both inner and outer camera frustums running all at full res, with no loss of frames or reliability, delivering a constant synchronized 24FPS in editor. The results, using the OSF GODBOX on-set computing platform, with native Unreal Engine or Unity 3D support and no middle ware, the results speak for themselves.

What You Need to Know about the new GODBOX™ Pro MKII

GODBOX Direct LED Processor Support 

Connecting the GODBOX Pro 4K outputs directly to the iMag studios Brompton SX40 LED processors, without the need for any third-party media servers or software, the simplicity of the GODBOX system proved to not only reduce overall system latency, it also allows users to use the power of the Brompton SX40’s LED processors directly to adjust the brightness, colour and temperature of the LED, giving users the ability to adjust the LED to any camera sensor.

 

Coincidently, as the RED brand name suggests on an LED stage we have found that RED cameras do indeed see a little more red on the RGB scale. That’s compared to the ARRI camera systems that seem to see more of the blue / green in the RGB curves. With GODBOX™ directly driving 4K HDR content to the Brompton SX40 LED processors, we were able to instantly adjust colour levels of the LED and pull out any RBG colour from the sensors vision at ease.

Go Directly from Your Engine to Your LED Processor  

But no matter what camera system you are using, thanks to how the GODBOX virtual production computers connects your engine directly to the LED processors just as if they where just a massive big screen 4K, 8k or even 16KK TV or monitor, GODBOX users can reduce their system lag, and deliver graphics to the LED processors at up to 120FPS as standard.

Book a GODBOX Demo at Your Studio 

OSF is proud of what we were able to accomplish considering our whole crew was under ten people and we had only 1 day to install and tune the OSF GODBOX system to the iMag LED stage. If you’d like to take a look at the GODBOX in action in your studio, drop us a line at [email protected]

Virtual production is digital production 2.0  

In the early 1990’s production computing happened, and it happened locally (digital cameras, desktop publishing, rendering). Whereas with virtual production these local processes now connect to the cloud, bringing all the benefits of cloud computing to every production that’s connected. 

Where local and cloud computing come together in computing terms is called the Edge” and where the Edge exists it is disrupting not only the content production industry, but all industries.  

At the Edge where humans, computing and high-speed networks combine they enable virtual worlds (services and applications) to be builtThese virtual worlds are often collectively referred to as the multiverse, metaverse or omniverse. 

Virtual Production Technology can be quantified by its ability to aid and enable the action of virtual production. Virtual production technologies when combined create virtual production systems. These systems are designed to provide specific virtual production functions, workflows and services.

How to Connect Omniverse Create to Unreal Engine

How to Connect Omniverse Create to Unreal Engine

Setting up Omniverse Unreal Engine Plug-in (Connector)

We take a first look at the NVIDIA Omniverse rendering platform and how to connect it to Unreal Engine. To start you’ll need to find and install the Omniverse launcher, Omniverse create and Unreal engine connectors. Theses are located in the “Exchange” tab underneath Apps and Connectors in the NVIDIA Omniverse launcher application that you download from here.

Once all software is set up (we run these tests on the OSF Godbox UE workstation with NVIDIA GPU) and you have your accounts made, decide on which machines are going to run what software. We suggest running each software (running Create app on one and UE on the other) on an independent machine.

On the Omniverse machine we’re going to create a local host server by going to the “collaboration” tab and selecting the “local nucleus collaboration service” settings option. This leads us to a web interface which allows us to control our local host and build new connections. 

In the connections section of the web interface create a new connection called “LocalHost”. Then navigate to the same place on the Unreal Engine machine and select “Add” this time when it asks for a server name enter the IP address of the Omniverse machine and sign in with the same details. 

Next launch Omniverse create and your Unreal Engine project on their specific machines. If the connector is correctly installed there should be a Omniverse Icon on the tool bar within UE. Under the icon is a drop down with the option to “Add server” in this box put the IP address of the Omniverse machine, this should prompt an engine notification stating either connected, or failed. This also creates a “Omniverse” folder in the content browser with your Omniverse servers IP and file paths. 

Once both servers are connected, right click the assets or map you want to collaborate on and select “export to Omniverse”. Then select the Omniverse server’s IP in the Omniverse folder and where you want the selected assets to appear on both machines. 

Open the imported map within Omniverse Create. Once the map is loaded and compiled, navigate into layer  and select the grey cloud icon next to the root. This makes all assets within the map Live and editable on both machines. Activate Live updates on the Unreal machine by ticking the “Live Edit” option on the Omniverse dropdown. 

We’re 98% there with a connection between both machines, live edits and shared assets. Now we just have to run the UE map as a USD. This is created automatically when exporting for Omniverse and is in the same place we exported the map previously.

Your very own XR Stage

Your very own XR Stage

Virtual production technology company On-Set Facilities™ have integrated StageCloud™ the worlds first sub £1m complete LED XR stage solution for filming in-camera VFX using tracked cameras and LED.

Aimed as a complete package for companies looking to own their own XR stage to shoot stills and video content the StageCloud™ solution is a complete 7m x 4.4m LED cave set up with ROE LED Diamond 2.6mm pitch walls, LED floor, Brompton Processors and a complete computing platform running Unreal Engine running on OSF Godbox™ computers.

 

XRstage

 

OSF Founder and Virtual Production Supervisor Asa Bailey said “LED prices are still too high for many companies, but as with all digital technologies, LED prices will come down, especially as LED manufacturers will look to widen their markets, we predict this will bring LED and StageCloud™ technology to many more companies over the coming years.”

OSF see their cutting edge developments in virtual production similar to developments in Formula E racing, where developments trickle down to consumer electric car production. Bailey goes on to add “in time, we hope that our stage technologies will revolutionise how we interact with the metaverse as we enter an age of immersive experiences, StageCloud™ will bring immersive computing to every room”.

 

StageCloud™

 

But for now, using StageCloud™ companies can invest in their own XR studio, to shoot on 3D rendered virtual sets. Any location dynamically displayed, matching any camera moves, bringing real-time  ion-camera VFX to entertainment of marketing content alike, only virtually.

As real-time rendering engines such as Unreal Engine become even more capable of rendering photorealistic graphics, more and more content producers will capture real-world environments and spin them up on an XR stage. Bringing any outside location indoors and by extending the LED stages physical area, using virtual set extensions generated in a game engine, potentially massive 3D virtual sets can be created.

 

 

Support for StageCloud™ is provided by OSF’s own worldwide network of engineers supported by additional crews from component manufacturers and VP crews. Already orders for the new StageCloud‹™ XR stage package are coming in, with the solution proving popular with companies in gaming, fashion and interiors. The first installations of StageCloud™ are set to role out in the first quarter of 2021. Anyone interested in owning an XR stage can email the StageCloud™ design and sales team at [email protected]
