How to Build a Video Wall for VFX! (Everything you Need to Know)

[@FortressAtLarge]

Best presentation I’ve seen in years. You made what others would consider complex, and broke it down masterfully. Amazing and impressive. Thank you for this.

[@TheNitroG1]

I work for an AV installation company, we do LED video walls. Still hoping we get involved in a project like this at some point. Since I program AV systems and am currently learning unreal engine, this seems like the perfect sort of project for me. I could easily spend a few days with something like that as my computer monitor. :D I play with ones that are 16ft by 9ft, pretty regularly but I can't usually pull up unreal engine and start playing around. For anyone wondering those panels run about 1700 a pop retail and the video wall processors are around 7500 each. so 56 panels wide x 10 panels high x 1700 dollars each = 952,000 + (4 x 7500) = 982,000. once you get 8 guys for 8 hours a day for 5 days at 150 an hour that's another 48,000. and the trussing I would have to guess is about 20,000 to 50,000. So 982,000 + 48,000 + 50,000 = 1,080,000. Guessing the budget was a million, as you will get a discount for a project with most manufacturers selling you a bulk amount of hardware. Could probably easily shave 100k off the cost.

[@phebe8866]

Hi, I'm curious to know how much the 16:9 ones you do cost?

[@L-A-M-E-nergy]

If also like to know how much the 16:9 ones you do cost… and do they curve around the subject like this big one does? And can a person actually run unreal engine 5 on it?

[@mylesdb]

Step 1: Convince someone to give you $1,000,000. Step 2: Build LED volume. Step 3. Underpants. Step 4. Profits!

[@DJDXD]

5. Also convince your local electrical company to use 70-80% of their electrical capacity

[@land-man]

@@DJDXD It shouldn't need more than an electronics store or a small company/workshop... It certainly needs strong current (three-phase current or something like that) for the building/the electronics, but that should be easy to implement if you can afford the video wall...

[@HerrPapa]

What an interesting video, man! I'm a 3D artist who might produce VFX with the help of such a volume in the future. Guys like you desevere much more credit for your knowledge and craftmanship! The VFX of Mandalorien is nothing without the solid foundation you just demonstrated! :)

[@LawnD4rt]

Good to see a channel in our industry.

[@serchenmorris1979]

Well done, similar setup in building video walls in Jamaica, for live events, we run out circuits @ 220v so we get to double the amount of panels per circuit by having the amount of amps per panel running @ the higher voltage... Loving the full explanation on the amount of processors used and the offset of frames... power, modules and the spline thanks much...very appreciated

[@thornescapes7707]

This is such a slick setup. Things have come so far, so fast. I can't even imagine where things are going from here.

[@leopixelstudios]

This is now my goto video as I'm planning my VP studio.. not as big.. more in the range of 21 x 12' ... Power requirement was a concern.. but not it's so clear!! thanks for sharing

[@stephenpearce3880]

Amazing vid. Tks for sharing. I watched first the Tony Robinson event that used such a wall (after Covid). It was amazing to see thousands of people around the world on Zoom, in mini tiles, all participating. Great vid buddy

[@VegasDominic]

This is so cool! The Mandalorian used 2.8mm pixel pitch - yours is 2.6mm pixel pitch which means yours has more pixels and a more high definition wall. Congrats on your wall, looking forward to seeing more content about your system soon. Would love to know the camera tracking system you’ll be picking for your Virtual Production. Glad that the Constellation 2M/E has genlock reference in. Hopefully that’s how we use it. Haven’t tried it either but looks like camera tracking, genlock cameras might be the next step after mastering the Unreal software. 😂 Those 560 panels are awesome! I wonder how many spare modules you bought as ready backup spares to plug / swap them in when needed. So true about the first layer making sure that’s it’s really leveled and so annoying when it’s hard to connect the side connectors being at the 6th row high and then seeing there’s a small line gap specially noticeable when there’s lighting from the back. Imagine having that when you’re at an event, 8am morning setup - then showtime at 5pm. 😂

[@zackhpittman]

Mandalorian was shot on ROE BP2, which has a MUCH better scan/drive rate with its IC's than anything blizzard offers. pixel density become less important the closer to 2mm you get, and more about the quality of the IC and Diode, and how they are driven.

[@leseton]

Every panel had 4 smaller panels you can Exchange

[@PutItAway101]

This system is so well designed and thought-out for quick setup

[@alexp7274]

Fantastic engineering on those panels. Well thought out.

[@Impactsounds]

Always wanted to learn about this. Thx for the video!

[@CamdenAvenue]

Dude this is crazy.... I am blown away....

[@godsgirl1977]

I'm ready to cry....I've been looking for something like this....now I just need to implement

[@timchambers5242]

Normally a single phase has active & neutral, when active is off it's safe to touch the neutral (if everything is working correctly). USA 2x 120v phases to make 240v means 2 actives, you can't switch off an active & touch the other⚡(it's not safe). In this case, both actives have to be switched off. Australia, Europe & others have 220~240v 1 phase, active+neutral+earth. Some installations will have ~400v 3phase outlet (3active+neutral+earth) & a plug in distribution board to provide ~230v circuits. Simple maths: if a panel needs 2A & the circuit is 20A (YMMV), then maximum of 10 panels per circuit. Check the panel power needs, quantity & venue supply long before the day to avoid unexpected surprises.

[@Gameplayer55055]

Is 400v better? I've heard that 3 phase can carry more power than 2 actives, and that americans struggle with powerful appliances like electric stoves and HVACs

[@HenryLoenwind]

Careful with that neutral. Even if everything is in top condition, there still is current flowing through you if any device is connected to any circuit on that neutral. The route through you, the ground, and the grounding point to the transformer is in parallel with the neutral wire going to the transformer. This splits the current according to the resistances of the two routes, and while those should be so different that next to nothing flows through you, it can still be enough to become dangerous if you are far away from the transformer, have good ground contact, and there is a high load on that transformer. This usually is no problem if you're in a residential setting with one pole transformer per house, but in an apartment block where dozens of flats are on the same leg of the transformer, or in a 3-phase installation...

[@HenryLoenwind]

​@@Gameplayer55055I think you're mixing two things up: Higher voltage and 3-phase. Higher voltage: The power you get is Volts times Amps. So if you want to run a 1200 Watt space heater on a 120 Volt circuit, you need 10 Amps (10 * 120 = 1200). On a 240 Volt circuit, you only need 5 Amps (5 * 240 = 1200). Just like filling a bucket with water---you can have fast-flowing water and a thin hose, or slow-flowing water and a big hose, the bucket fills at the same speed. However, just like that thinner hose that has to withstand higher water pressure from the fast-flowing water, a wire with a higher voltage needs thicker insulation to keep the electricity in. That big hose needs more space inside, and the same is true for wires---higher Amps need a thicker wire. In the US, with its split-phase system (i.e. 2 hots that have 120V to neutral, but 240 to each other), you get the worst of both worlds. You need a thicker wire and thicker insulation. Not that it really matters; the difference in insulation thickness is virtually non-existent, as the insulation needs a minimum thickness for mechanical reasons anyway. But this now gives you the effect that the exact same wires can transfer double the power if they're run at 240V instead of 120V. The wire thickness limits the Amps, so you can't just double the Amps to compensate for the lower voltage, like in my example at the top. 3-phase, on the other hand, uses a weird little trick to conduct the same amount of power with 3 or 4 wires as 3 pairs of wires could transmit. To explain that, I need to explain AC first. With AC (alternating current), there isn't a constant flow of electricity, but it flows forward and backward like the blade of a jigsaw. Now imagine 2 jigsaw blades that are connected to the two sides of a seesaw---when one goes up, the other goes down. The pivot point of the seesaw never moves up or down. The same also works with 3 jigsaws and a triangular seesaw. Or with electricity, where the 3 phases are the jigsaws and the neutral is the pivot point. If the load on all 3 phases is identical, there is no current flowing on the neutral---there isn't even a neutral wire (that's why I wrote "3 or 4" above). The neutral is only needed when the loads are not balanced, for example, when they are broken out into single phases to connect normal devices. Now, where do those 400 Volts come into play? In a 3-phase system, there are two ways to measure voltage: Between any of the phases and neutral, or between any two phases. If you get 400V from the latter, it means the former is 230V. If you have 120V phase-to-neutral, you have 208V between the phases. Or you can have 480V/277V, or 415V/240V. You might have heard of those voltages before... Oh my, did I slip into lecture mode? Oops, sorry.

[@Gameplayer55055]

@@HenryLoenwind your explanation is great, I've enjoyed your analogy with water plumbing. Electricity is almost identical to water plumbing in functioning. My biggest question is why america has chosen not so great way to distribute power, while europe has both higher voltage and 3 phase. Makes more sense because you have more power & electric motors are very easy to drive with 3 phase without the need of pesky capacitors. But I think electroboom would get killed with 220v either lol

[@Gameplayer55055]

@@HenryLoenwind mentioning neutral, some clever assholes are getting power from neutral and earth(using water pipes), and getting a "free" energy this way. This works with soviet systems where earthing isn't a thing

[@spencercollins7676]

Great video. I shoot and produce on a virtual wall in Canada and found your video in hopes to address an issue we have been having. We seem to get horizontal scan lines on video whenever trying to add movement to our camera. If the camera is static, we can sync the LED wall to the frame rate of the camera and don't get scan lines - but when trying to do jib moves or gimbal moves - it always produces scan lines. I'm guessing because of the rolling shutter. Do you have any tips or tricks that you have used? Or anyone in the comments? Thank you

[@L-A-M-E-nergy]

Real Talk! What’s the brass tax? How much was all of that to build and run? (Including what the monthly rent is and electricity cost for the facility?) Just trying to figure out how much money I need to build a smaller wall but similar layout?

[@frown]

You mentioned the controllers have HDMI (that you plan to use) and the panels are also daisy-chained by ethernet. But what are the other cables we see, they kind of look like XLR, what cables are carrying the actual video signal?

[@liveproductionmastery]

SDI is another one of the video inputs which can carry 12G signal meaning up to 4K 60fps DisplayPort is another video input option that can do even higher frame rates and resolutions. But you can’t run the signal as far. SDI can run reliably at about 300 feet. Then you can rescale the signal with a decimator to run it farther if needed. These processors do not have fiber video inputs or loop throughs unfortunately

Those panels should be mounted somewhere a lot more stable and definitely not on the tubing for the monitors.

[@mikeo5657]

How much heat does that throw?

[@moe85moe85]

Amazing equipment, what’s it cost to do a setup like that

[@benjaminaburns]

It looks like they are using Blizzard IRiS Icon 2.6, maybe $1,400 each (without bulk discount). 56 panels wide x 10 panels tall = $784,000 . Not sure on the video processor units, maybe cheaper, but probably $75,000 for the 4 hubs + 4 processor units. Add another 15k for smaller things: metal rigging, electric equipment like panels, miles of cabling, storage for everything. Total: Probably a bit under $900,000 on just materials, without any spare parts.

[@Kervie100]

Great video!!!!! Can you tell us how you got your single 4K output to work on the full wall? Especially with no tearing. Keep up the great work learned a lot here 😊

[@liveproductionmastery]

Yes, all the HDMIs in the processors are daisy chained. Then I set EDID of first processor to the widest I could get it and in the same aspect ratio of the wall. Then in the first processor I set the canvas size to 1/4 of the wall and places it on the far left side of the laptop output image. I repeated the canvas size for the other 3 processors giving each one its own 1/4 of the laptop output image. So each processor is scaling up the image to display on the wall. I’m running at a lower resolution then the wall but sizing up to making it fill the screen. Hope that helps.
