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

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

@@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...

@@DJDXD 200 amp * 240volts = 48kw

Did you think this was a diy for someone’s hobby

@@squidport_ would be fun, think I might take it up 😅

I’m glad it’s helpful! Thank you for supporting!

The led panels are relatively affordable for what they do, the config for what you want them to do well that's a nightmare

It’s available to consumers

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.

Every panel had 4 smaller panels you can Exchange

I wouldn't let Linus (from LTT) anywhere near these panels & assembled screens. Something is typically pushed/dropped.. and broken. Unless you intend to test if it's Linus proof.

this is why i love youtube comments you get people from all walks of life and success levels congrats on the mansion buddy.

KID, You are good. :)

I can help briefly, a 192 x 192 panel that is 500mm x 500mm indicates a 2.6mm pixel pitch. @10:45

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.

@@liveproductionmastery thanks for replying. I am going to try this on a smaller wall just to practice.

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

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...

​@@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.

@@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

@@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

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.

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
