Call Me Snek

Gonna step into the waters here too and I really hope it comes across that I want to help and educate as much as possible here, seeing a lot of misguided comments on youtube.

Dante is not "meant" for any specific use case. Install, rental, corporate, tour, they all use it, it's just audio over IP. The biggest tours in the world use it for some aspect of their production and you've definitely been to a concert where you heard audio because of Dante. And until AVB Milan is more widely adopted, Dante is what you'll see in a lot of installed applications for professional live sound in most venues.

I read some misguided comments on the video saying 40 speakers will cause issues because of the multicast traffic. Proper multicast flows with IGMP snooping running on the same stack of switches (Brand, model, properly configured) will handle a single to many source just fine. My gig at the moment runs with a bunch of CL/QL mixing desks, rio's, AVIOs for drop down boxes, Virtual Soundcard instances, many Axient digital and ULX-D racks, and a bunch of other stuff that all adds up to channel counts in the thousands with no dropouts.

Please don't try to integrate your public (physically accessible to everyone, and very, very busy) network with the Dante audio net. Dedicated, physical switches for Dante is the best and reliable way (Netgear AV line or Cisco 350, used both, both are rock solid. Yamaha and Luminex are also good but they're quite old now). Putting other traffic on that net quickly leads to audio dropouts, subscription issues, PTP errors, devices disappearing, unscrupulous LAN goers putting their own audio on any device on the network if a vlan is left accessible...

Redundancy is your friend in the world of network audio. If you can run two cables (It's a new build, you totally can), run two cables.

And I can't speak to Dynacord, quick google leads me to believe it's a *fine* matrix mixer and audio processor. But for the sake of all the flexibility, reliability and power you should at least look into QSYS for your audio and A/V control system, I think you'd be much happier with that in the long run. Audio, lighting, and video control systems all in one very capable box with so many logic systems you can program and fantastic support.

I LOVE the flexibility that individual PoE pendants and ceiling speakers get you. Every speaker is an endpoint and it's how I'd want to build it! But it's always a good exercise to plan a distributed 70v system with plenty of zones to see if you can get the same or better coverage for less $ and complication.

Is Linus going to end up murdering Jake with an Intel CPU, instead of firing him? We need answers to this highly important question!
 
But as to why folks still go for Intel, it's generally less painful to deal with Intel hardware: Their driver updates don't brick your OS or hardware 😅, they tend to hit the listed hardware specs with some margin to spare instead of the several pages of footnotes you run into with AMD, they seem to test things before they release them to the public in most instances (Arc seeming to be somewhat of an exception), Intel has pretty good compilers that can target specific CPU models while AMD's equivalent (AOCC) is somewhat crummy which can really make a difference in math heavy applications, and if there are issues Intel is often surprisingly quick to fix things. Meanwhile, none of the above things are guaranteed with AMD, so I can totally imagine companies going for Intel until AMD gets around to fixing their reputation on these matters.
 
There've been other issues, like some of the Athlon 64 SKUs had some odd issues with running the Sun JVM, it worked but it was so painfully slow it was defacto useless, meaning you had to run the Microsoft JVM.

Unfortunately even if you saved 100K on it ultimately the problem is always the same; is Linus going to answer a call at 5AM on Sunday for direct support on a server he built? Or even on a regular workday at a reasonable time considering he has a full time job? Does he have a replacement just sitting there so he can ship it to the customer as a placeholder while he fixes the machine in case something goes terribly wrong? If you can't afford much downtime and you don't have specialized staff who can sort out issues very quickly you're kind of forced to buy off the shelf from an enterprise OEM.
 
Now granted, it's kind of absurd that Lumaforge doesn't offer redundant power supplies so maybe they aren't really delivering on that front either.

I'm perplexed why an audiophile portable rack and some 15-18" depth rackmount cases to fit everything was considered.  This would also permit inclusion of a good rackmount switch and leave room for a UPS (though shipping the UPS across boarders might be problematic, you'd have the room*). The downside is that you'd have to ship it via freight but those cases are designed to be abused in transit.  Hotels generally can hold some freight and it is always courteous  to work with them ahead of time to be prepared to received the gear.  Doubly so when going across borders to account for custom times.  
 
An alternative to freight shipping and dealing with customs would be to have some one drive it down since it is 'only' Canada to the US.  Custom checks are relatively painless, you can move more and you have a built-in chain of custody presuming it is a member of the team driving it.  Less lead time is necessary vs. freight but I'd still plan for a buffer in case anything goes wrong.  The unused buffer time can be used for prep at the hotel prior to everyone else's arrival:  you'd have the network built up and tested as people are arriving to the hotel.  If you reserve neighboring rooms, often there are side doors connecting them all which you can run cables underneath.  Literally get everyone on to high speed hardwired network.  The downside is that this removes members of the staff for rather mundane work that'd otherwise be doing something else.  Gotta weigh the cost-benefits here as man power and insurance are factors.
 
There is yet another solution being Las Vegas:  rental gear from various AV production companies.  Most have huge warehouses in Las Vegas due to the numerous shows taking place there.  Various Dell/HP/Lenovo workstations can be rented ahead of time and delivered to the hotel without worry from customs.  Same day replacement options are possible (still buffer in some setup time prior to production).  Items like storage would have to be flow in but straight forward.  This setup can be tested ahead of time by having a unit shipped to the offices and mocked there.  It might even be possible to arrange for the same unit used in the mock to be the one used in Las Vegas.  This eliminates much of the freight shipping but the upfront costs are not cheap.  This can still provide savings if you have good tracking on how much your logistics cost.  One downside for CES in particular is that you have to get in your rental requests early.  CES is one of the few shows that can drain inventory.
 
If carry-on was a requirement due to the costs, have you considered breaking the system up across multiple chassis and multiple carry-ons?  Just moving storage externally frees up so much volume in this design.  
 
Or why not do things the LTT way and build a custom case that'd be purpose built to fit inside the Pelican box?  You'd be able to put in larger motherboard, have hot swap drive bays and utilize far more powerful hardware even after losing some volume for the necessary vibration mounting/foam.  To actually run the system, the Pelican case would have to be open like it was sitting on the table in the video but inside a hotel room this is not a big deal.  Obviously you can't put ventilation holes into the external shell. There is a time-cost-benefit analysis that'd need to be done for this.  For a media company like this though, the ROI could be spread out across over multiple trips, especially if the internal rig adheres to motherboard/component standards for upgrades later.  
 
Also good to see some testing done prior to shipping.  This will need to be repeated upon arrival before production work starts on it.
 
*One of the things I've learned for trade shows is that if something is deemed mission critical but complicates shipping, consider purchasing it locally and having it shipped to your hotel.  If you're already shipping freight there, the hotel will also accept a package.  It is possible to flip such things quickly on CL or eBay to recover some of the cost after the event is over.  
 
Vibration rigging so that you can ensure that damage done to the case doesn't get transferred to the components on the inside.  High end travel cases suspend the contents so that the exterior can be dented or even ruptured without damaging stuff on the inside.  It is possible but generally custom built which means not cheap.  
 
It is worth pointing out that this video's solution negates any sort of protection for the items inside due to the tight fit.  There needs to be some interior padding, especially for that fragile InWin case.  That looks like I could wrap it by just staring menacingly at it.

The video should be updated with more info/testing with different PCs/Macs using different connection modes.
 
The XDR has a Titan Ridge Thunderbolt 3 controller which can accept Thunderbolt or USB-C with DisplayPort alt mode input (Thunderbolt is also an alt mode of USB-C). The XDR supports the following input modes:
1440p HBR (good for booting) 4K 10bpc HBR2 5K 8bpc HBR3 (not sure about this one - needs testing with a DisplayPort 1.4 GPU that doesn't support DSC) 5K 10bpc HBR2x2 Thunderbolt 3 (from Alpine Ridge)  6K 12bpc HBR2 DSC 6K 12bpc? HBR3x2 Thunderbolt 3 (from Titan Ridge) The XDR display is 10bpc but allows 12bpc input. The 4K, 5K, and 6K modes have timings for the following refresh rates (Hz): 47.95, 48.00, 50.00, 59.94, 60.00. I don't know if custom timings are supported. The 1440p mode is only 60Hz. The timings for the lower refresh rates are strange because only the vertical blanking is changed. The pixels are drawn at the same rate for each refresh rate (so the same bandwidth is required for all refresh rates). This means each frame is drawn in the same amount of time but lower refresh rates will show the frame for longer. Bandwidth is reduced for lower frame sizes though (so 5K and 4K don't use the same bandwidth as 6K).
 
For USB functionality, (brightness control, USB ports, presets):
A USB-C with DisplayPort alt mode connection includes USB 2.0 (4 lanes of DisplayPort leaves no lines available for USB 3.x).
A Thunderbolt connection uses PCIe tunnelling to the Titan Ridge USB 3.1 gen 2 controller of the XDR display's Titan Ridge controller. But HBR3x2 reduces bandwidth available to USB 2.0 speeds. The USB ports and devices are connected internally with a USB 3.0 hub. How is the USB speed limited? Is the hub connection reduced to USB 2.0 mode or is it only limited by the reduced available PCIe bandwidth? For example, a USB 3.1 gen 2 (10 Gbps) PCIe card can work fine (but with reduced bandwidth) in a PCIe 1.0 x1 slot (2 Gbps).

Nvidia RTX, AMD 5300M, 5500M, W5700, W5700X, 5700 XT support DSC. Until recently Intel graphics have been limited to DisplayPort 1.2. Now there are Intel CPUs (10th gen CPU, Gen 11 GPU, Ice Lake) that support DisplayPort 1.4 and DSC, so now the Surface Laptop 3 can support 6K.
 
RTX has a USB-C port that supports DisplayPort alt mode so it works with the XDR display. The USB-C port of the RTX also supports VirtualLink alt mode. Do any available VR headsets support VirtualLink? Anyway, the XDR does not use VirtualLink. The W5700 also has a USB-C port but I don't know how it works for macOS/Windows, or if it supports USB with DisplayPort alt mode.
 
For GPUs that don't have USB-C, a bidirectional USB-C to DisplayPort cable (such as the one sold by Moshi) will work but you'll be missing the USB features of the display. Maybe an app can set brightness using DDC/CI?

If the GPU doesn't support DSC, then you'll be limited to 5K or 4K unless the GPU has two DisplayPort HBR3 connections to a Titan Ridge Thunderbolt 3 controller. However, the firmware of the controller might limit one or both connections to HBR2 or HBR which makes 6K impossible (this requires more testing). There was a problem with the Blackmagic eGPU where it would only allow two HBR2 connections to the XDR display (supporting only 5K). They released a firmware update to fix that. With a GC-TITAN RIDGE, when I connect two HBR3 displays, one of them can only connect at HBR speed. In macOS, the AGDCDiagnose command is used to get connection information (DisplayPort lanes, speed, DSC, HDCP, MST, etc.). Even if you get dual HBR3 over Thunderbolt 3 to work, I haven't seen an EDID that includes the 3008x3384 timing that would be required to support the tiled mode but that might be just because I haven't seen the AGDCDiagnose output from this connection mode yet.
 
6K is a lot of pixels (more than dual 4K which is more than 5K). A card that supports DSC and has 6 DisplayPort outputs (such as the W5700) might not support six 6K displays. Apple's Mac Pro tech specs says the AMD Radeon Pro Vega II can only support two XDR displays instead of the expected 3 (only 3 because it doesn't support DSC). The Mac Pro tech specs and the support document for the Radeon Pro Vega II Duo MPX Module have conflicting number of supported XDR displays. Is there a problem with 6K transport from the MPX slot to the I/O card or top Thunderbolt 3 ports? I don't think so, since that is the only way for the MPX 580X to support 6K.

Our initial strategy was to start with a "clickier" title and replace it with an "SEO optimized" one after the first wave of viewers.. But over time the importance of SEO has given way to the importance of attracting clicks for content that is shown to potential viewers algorithmically. 
 
Since we made the titling/thumbnail change about 2 years ago, we've experienced phenomenal growth. You might not like the stupid titles and thumbnails (neither do I) but we are running a business here and running a (successful) business means following DATA, not FEELINGS.

We are having our best month ever (tracking over 90M views for December) by a country mile. I don't like that it works, but it works.
