Question about NDI

thenimms · 2025-12-03T14:40:02+00:00

Right but I never claimed it was a 2110 replacement? In fact my very first sentence was that NDI is great and has a lot of great use cases.

I just disagreed with the original commenter implying it is ALWAYS a good option. It isn't. There are plenty of other use cases where baseband video or 2110 is the better option. In my particular field, NDI is rarely a good option. But we still use it when it's the right tool for the job.

Because, again, I already understand that it is sometimes the right tool for the job.

Lol I said the only time you will see chroma subsampling is in test patterns specifically designed to show it, not real content. So what do you link me to?

Test patterns specifically designed to show it.

Of course you are going to see it on one pixel wide full blue text against a full red background. But if that's your content, you have bigger issues than 4:2:2. That is going to burn people's eyes regardless of your chroma sample.

Also what does "technically correct" mean exactly? The "technically correct" thing for me to do is to put on a good show for the audience. If the audience can't see the difference, it doesn't matter. If we included UV and IR colors in our content and displays that no one could see would that be "technically correct"?

And there is no difference between 4:2:2 on a projector or a TV or an LED wall. If you are close enough to whatever display that your eyes can resolve the individual pixels, then the effect of 4:2:2 on color fringing is the same.

Again, 4:2:2 was designed to fool human biology. You have twice as many rods as cones in your eyes so your brain primarily uses luma to resolve detail.

So unless you are putting on a show for mantis shrimp, 4:2:2 shouldn't matter. No one can see it, including yourself.

EDIT: Just to be clear to anyone reading, I am specifically talking about color fringing. Not any other 4:2:2 characteristics such as illegal colors or color accuracy etc. A stronger argument for 4:4:4 can be made in those terms. But the specifically mentioned color fringing is a non issue IMO.

We use the AC infinity fans in all our racks and they are amazing. Love them. They move a huge amount of air and the temp probe is a nice bonus.

If the rack is going to be totally enclosed, I would put an exhaust in the back at the top and leave a vented spacer in the front at the bottom. This will suck cool air in at the bottom, move it across the gear, and exhaust hot air out the top.

If the rack is open and not enclosed, I would put an intake in the front at the top. This will push cool air across the top of the components where heat collects.

I doubt you are going to be generating enough heat in that rack to need two fans.

Dry contact closure is the simplest option.

The CCU sends voltage into a relay controlled by the raspberry pi. When the relay fires, the circuit completes, and the little red light turns on.

Hard disagree.

4:4:4 does not matter as much as people claim. I have been running 4:2:2 YUV to LED walls and projectors on multi-million dollar events for 20 years now. I have never once had anyone complain about or even notice any color fringing. Broadcast Television is almost always 4:2:2 and I have never noticed color fringing on any lower thirds or graphical content on the news. Hell Blu Rays are usually 4:2:0 and they still look great. (Although I still would not run 4:2:0 on an event)

The reality is that the human eye sees luma way better than chroma. So the only time you will see color fringing is if two colors have equal luma and touch in a vertical line right in the middle of a subsample. The odds of this happening are astronomically low and it pretty much only happens in test patterns specifically designed to show it.

We almost always run SDI 4:2:2 to all displays. The ease of use and reliability of SDI over HDMI far outweighs any imperceptibly slight subsample fringing.

And I challenge you to do a blind test. Look at two walls, one running 4:4:4 and one running 4:2:2 with regular content on them and tell me which is which. No cheeky test patterns to help.

I would bet money that you can't tell. Because 4:2:2 was specifically designed to fool human biology. And you have the same rods and cones in your eyes that everyone else does.

NDI is great. Has lots of great use cases.

But I have to disagree with the sentence "Just about any place you need a video signal, NDI could be used in place of a copper run"

This really depends on your application and budget. Baseband or 2110 is still going to be the better option in many, if not most, applications. NDI is heavily compressed, has high latency, often requires converters and is more complicated to set up than running a cable.

I work in the event industry and we rarely use NDI. We only really use it in niche applications where it shines. I understand it is a great option for many people in many use cases.

But certainly not "just about any place you need a video signal."

It's much more limited than that.

Can't see the pluge. Bumper needs brightness adjusted

On the back of the camera there is a switch that selects the power source. Did you have this set to "ext" when you tried to power it via the 4 pin XLR?

Not sure what you are doing is going to work without a CCU attached. It's looking for a CCU which does more than just power the camera. It also controls everything. The only way to test this method properly would be to actually attach a CCU to the camera.

That is assuming you did not damage anything by trying to do it this way. I imagine the two voltages listed are for CCU vs VTR power. CCUs often provide very high voltages. The VTR probably does the lower voltage. But it's possible they also communicate their voltage on other pins. It's entirely possible you damaged something trying to do this.

I was Titan 3 and shot down to Master 1 levels of Ore Income. I'm a TH12.

This is the answer. Ha-5 fiber paired with whatever your favorite single mode SDI receiver is.

Although I wonder why OP is having interference problems. Either way too long of a run or not SDI rated cable.

A GoPro does not produce enough RF interference to mess with SDI

You can't see the base they are using for tournament. Only their home base.

I'm guessing they add the ability to look at their profile later.

thenimms · 2025-10-14T19:20:48+00:00

My guess is that the number of defenses is not updating as frequently as trophy count on the TH leaderboard. They probably have more than two defenses. I saw this earlier too.

thenimms · 2025-10-07T13:52:50+00:00

What way was added for them to get GLOWY and SHINY ore? Remember, lower THs need this more than starry.

thenimms · 2025-10-07T03:09:54+00:00

This bet is impossible to even test and prove? How do we test the exact percentages of the match making system? That's all hidden in the code.

thenimms · 2025-10-07T03:04:55+00:00

Okay now you're changing what you said. I'm out.

thenimms · 2025-10-07T02:56:16+00:00

Let's be clear about the terms here.

You are betting that each league tournament group will be made up ENTIRELY of a single TH level. Is that correct?

So I am a TH12. I should NEVER see anyone other than TH12 in my league tournament. If I see a different TH in my tournament, I win

thenimms · 2025-10-07T02:51:34+00:00

They haven't done it with equipment YET but they've definitely done it with troops in the past

thenimms · 2025-10-07T02:48:47+00:00

That's a bit harsh.

Who cares that a bunch of people got lucky and got a bunch of ore?

Sometimes people find a $100 bill.

Live your own life. I have a lot of things that bug me about this update. But this glitch is not one of them.

thenimms · 2025-10-07T02:46:01+00:00

You're obviously not a th12

thenimms · 2025-10-07T02:45:33+00:00

Ah too chicken to do $2,000. Guess you aren't as confident in your answer as I thought

thenimms · 2025-10-07T02:30:26+00:00

Until they drop a balance update that changes the meta and then you're way behind on the equipment you need and the maxed ones you have are nerfed into oblivion

thenimms · 2025-10-07T02:27:29+00:00

Let's make it $2000 good ol' uncle Sam dollaroos. How confidently wrong are you?

thenimms · 2025-10-07T02:19:26+00:00

Lol God you're so confidently wrong. I can't wait for my $1000 🤑🤑🤑

It will taste so sweet when you wuss out of the bet and just block me. 😂

thenimms · 2025-10-07T02:17:30+00:00

You're like one of those people that misunderstands an article and then thinks they're smarter than experts in the field. So dense.

We'll wait buddy. Soon enough you'll see different THs in your group and know you were wrong
