The Silent Killer of Virtual Production (and How to Avoid it!)

The first season of Disney's The Mandalorian ran into some serious issues with their LED volume while filming using virtual production. Moiré cost the show hundreds of thousands (maybe more!) in post-production fixes.

Moiré, more commonly known as aliasing, is a serious problem in virtual production. Today, we establish easy fixes to this problem that you can use on-set to quickly find a solution without having to re-calibrate your LED Volume.

Camera filters also helps a lot.
A black promist or even a simple Soft can reduce moiré on LED volumes without having to shoot with a shallow depth of field ;)

What we have done on productions is to use frosted lighting gels or rear projection screen infront of the actual LEDs this will almost remove the risk of moiré.. Just an alternate solution... ;o) Great Video...

I mean the way they did it on the Mandalorian was to just roto every single shot in the volume and replace the background digitally. They essentially just used the volume for volumetric lighting on his armour but every single shot you see the BG has been replaced digitally.

Fantastic video. I have found diverging the led position in the x, y that Moiré is radically reduced and as there no defined overall pattern between the camera pixel matrix and the screen pixel matrix. The led tile looks kind of odd as the LEDs look like they have just been splatted onto the panel by a shotgun. There are also a number of other issues when using an LED screen as a volume all of which can be addressed, this requires a led panel to be made for LED volume not using existing rental panels which are not really ideal for the purpose of background or even a green screen.

Why won't they just use projectors and screens instead of LED-Screens? It would get rid of moiré-effect and you would have the benefit of the possibility to focus on the screen? Also seems to me that projectors would be cheaper? Just mirror the image and put the projectors behind the screen.

Good, slick video on an industry that is similar to what i do. Rare to see an account that details the hectic and unbelievable life of live and XR event technicality. Subscribed!

Learned a lot from this! Including how to say moiré, finally 😬 thanks guys!

I've always wanted to visit Moiré, where is it in Europe?

[joachimkarstens]

if you shoot shallow depth you can just juse a greenscreen :D Use soft camera filter. Of frost in front of the LEDs

When the moon hits your eye, like a big pizza pie, that's a-Moiré!

We have a red line on our studio floor about 4.5 meters out from the wall. Do not focus past this point. 🙂

[sohrabhosseini]

genlocking, phase shifting, scan rate of panels and many other things are important!

What companies build the screens? I know about Stagecraft, but whos actually making these? Please no hate, just curious

[andreizhitkov]

It has noting to do with the screen resolution exceeding the camera resolution. It has to do with pixel pitch of the camera's image element being a close match to the pixel pitch of the screen projected on that element. Be more scientific!

Kind of sounds like a problem nvidia would throw their Tensor Cores at
