Hi,
I am looking for some guidance on remedying NDI drops on a new Laptop. The peculiar thing is it only drops when the source is from a vMix output (1-4). Any other NDI source such as Birddog cameras, Cinergy Playout Software, Kiloview SDI to NDI Converter are all perfect. It is only vMix sources that have a problem. I have ruled out the network as any other computer on the same network and cable works perfectly. I have even tried external USB to ethernet adapters with no luck.
The computer is a Lenovo 13th Gen Intel(R) Core(TM) i9-13900HX with 32Gigs of Ram and a 4080 graphics card running Windows 11 Home.

I have been struggling with this for a few months trying to resolve the problem. I have reinstalled Windows, made sure the Network driver was current, updated graphic drivers etc. I was running vMix26, but have since upgraded to vMix27, no change. The Problem also shows up on Studio Monitor.

Any suggestions are welcome.

Regards

If the problem shows even up on studio monitor this must be a lack of resources. vMix is using full NDI as outputs. They are high bandwidth. Maybe take a look at the network utilization.

What's the negotiated speed of the network adapter? Is it 1GBit/s?

What type and chipset is the builtin network adapter?

Hi Mavik,
It is unlikely a lack of resources as the specs of the computer are quite high (see original posts for specs) and this happens with only 1 input to the computer. Using the same network-switch-cable combination on a much lower specked computer the NDI feed has no problem, so it is not a network issue as far as I can tell. Also, non vMix NDI sources (Birddog, Kiloview etc.) work perfectly well, it is only vMix NDI sources that exhibit this issue. The problem exists on any vMix source from any computer on the network, so it is not from 1 source or 1 specific computer. So long as it is a vMix souce the drops are very high. I have tried Birddog Dynamo to view the traffic, and I can see all the drops on the vMix souces while every other NDI source is perfect.

Hi, it is a 1Gb adapter and I have also tried a 2.5Gb adapter. The default 1Gb adapter is Realtek chipset. As indicated, it is only with vMix sources that the issue exist. Othjer non vMix NDI sources are perfectly fine.

Have you tried updating the vMix NDI files manually to the latest available?

Sorry to rehash the thread. Did you find a solution for this as I have the same problem. Any NDI source to vMix plays perfectly but if NDI source is from another vMix PC, it starts to stutter.

Unfortunaey I do not have a resolution to this as yet, but I am continuing to test when time allows. Should I find a solution, I will be sure to update this post

As I said you could try to update the NDI to the latest manually in vMix. If it's vMix to vMix you could try SRT instead and see if the drops are happening there as well.

I have manually updated to the latest NDI in vMix to no avail.

Just to jump in to say that I've started to experience this issue recently. No logical reason for it. Only on incoming sources.

I can use NDI without problem in my network. We have 12 PTZ NDI cameras in network and can work with all of them without drops but cant receive any NDI from another Vmix.
Vmix NDI works good for long time but now it´s a big problem... Vmix Doesn´t work anymore.

My experience is that it tied to vMix. If the source is a vMix ouput, I get lots of drops, freezing etc. Any other source on the same network is fine.
