NDI Scan Converter disables G-SYNC in UWP fullscreen games

Par colecodez
I have noticed an issue where G-SYNC gets disabled when I turn on NDI Scan Converter. It only affects UWP windows games in fullscreen which unfortunately includes the game I play most, Apex Legends.

To test this I had to enable the G-SYNC overlay in Nvidia Profile Inspector. As soon as I enable Scan Converter (from a stream deck macro), G-SYNC immediately disables. As soon as I kill Scan Converter, G-SYNC enables once again. I noticed that G-SYNC still works with Scan Converter if I play in borderless windowed mode but there is a noticeable stutter.

Just wanted to shed some light on the issue for devs and see if anyone might have found a workaround? Specs below.

ASUS ROG Swift PG27UQ 27" LED 144Hz 4k G-SYNC

NDI over VPN with two Fritz-Boxes

Par MDCommander

I have a problem with the connection of two computers via VPN to get there with NDI the camera from PC 1 to PC 2.

I'll describe the structure very briefly:

The first camera is connected to PC 1. The PC 1 (IP: is connected to the FritzBox 1 (IP: This is via VPN tunnel (manufactured by the FritzBox 1 to the other FritzBox 2) with another FritzBox 2 (IP: connected. At the FritzBox 2 is a PC 2 (IP: connected. On PC 2, another camera is installed. On PC 2 should then run the StreamLabs OBS software and I would like to receive there via NDI input the camera 1 synonymous on the StreamLabs - OBS. But I do not see the PC 1.

A connection from the tunnel between the two networks ( and respectively .0 at the end, is definitely available. Printers from both networks can be accessed from any PC. So the tunnel works fine.

How can I get it because that the camera 1 from the PC 1 via the FritzBox bin to PC 2 can send your data?

I wanted to get the screen of a remote computer or the camera on a remote computer on my streaming PC (PC 2).

Do I have to stop something? At the Fritz boxes or at the NDI plugins?

In the same network, so if I would infect the same computer s.die same FritzBox, then I immediately with my streaming PC PC 1 in the selection list and I can also directly to the camera, or access the streamed signal. That works ... but as soon as I have the VPN tunnel of the Fritz boxes in between, it is not more ...

Do I have to adjust in the Fritz boxes that something should be rerouted? Any ports or something?

And if so, how do I do that? Or can I enter the destination address of the NDI tool somewhere?

The following software is used:

PC 1:
OBS Studio in the latest version (24.0.3)
NDI 4 runtime
NDI 4.7.0 (Installed by Installer)

PC 2:
Streamlabs OBS (Version 0.18.5)
NDI 4 runtime
NDI 4.7.0 (Installed by Installer)

Fritz boxes (7490 and 7560) each have the latest version on board ...

Can someone help me please? Or is it not technically possible to show the camera or the stream via a VPN tunnel?

Thanks in advance.

NDI Tools silent installer component switches

Par pvillarragut

We need to execute a silent installation of Newtek NDI Tools and select only "NDI|HXI Drivers" component . I checked the /silent options of the installer and I find the /COMPONENT flag. But if I select /COMPONENT="NDI|HXI Drivers" the component options is not selected.

Do you know which component words is assigned to NDI|HXI Drivers?


NDI 4 Tools - Adobe CC Plugins - Character Animator not showing NDI as an option

Par eeeniebean
Hello all,

I have Character Animator installed through Creative Cloud on Windows 10.

Downloaded Newtek NDI for Creative Cloud from

(and yes, I made sure to include the options for CC, I/O, etc. - screenshot attached)

The NDI option just will not show up under Live Output under Preferences in Character Animator.

I've looked around for that NewTek_NDI-Transmit.prm and can't find it anywhere, and I'm having no luck finding documentation of what the plugin should be.

I've uninstalled NewTek, rebooted, re-downloaded (making SURE the CC options were selected) and re-installed. Still no luck.

NDI is working - I can run the test broadcast, and I can even get the test broadcast to come in as a source on streamlabs OBS.... I just can't get Character Animator to give it as an option. Seems like it must be a problem with a missing plugin but I can't find it (or documentation for it). Help!

Specs: Character Animator 3.0

Windows 10

NDI loaded 11/24/19.

This Adobe forum thread seems to suggest that I just need to find NewTek_NDI_Transmit.prm.... I can't. Other folks in the same thread seem to be having the same issue.

Can anyone tell me what the plugin for Character Animator is called and where it should be located? Is it the same NewTek_NDI_Transmit.prm? If so - what to do if it's not coming through on the installer?

My next step is to install Premiere just to test out if I can get an NDI output from there. Beyond that I was going to try it on Mac Instead.
Happy to provide any other info or screenshots that might be helpful.
Thanks so much and Happy Thanksgiving to those who celebrate.Click image for larger version.

Par rlambert
I am about to take the plunge and buy four NDI cameras for my studio.

Several years ago I heard Dr. Cross from Newtek say that NDI-HX delivered the same quality of image as regular old FULL NDI except for two things:
1. NDI-HX used less bandwidth 20MB vs 140MB
2. the NDI-HX has more latency due to encoding long chains of data....this higher latency being the cost of keeping the image the same quality of FULL NDI.

All in all, he strongly implied that the images were identical.

Now that I am shopping for Cameras I see that some companies make a big deal that their signals and converters are FULL NDI. Other companies like PTZ Optics make a big deal that the images are pristine with NDI-HX

So here is my question.

For a small studio (4 cameras) with plenty of bandwidth (10GB dedicated ethernet) is there an advantage in going with "FULL NDI?"

If all of the cameras are NDI-HX the latency will be consistently higher, but, isn't that not a big deal if they are all the same latency?

Please help me with advice. I am ready to purchase these cameras now; but, can't seem to find a straight answer on this.

Thank you very much,


Quick Tip / NDI camera App/Virtual Input

Par Tek_Soup
I recently was messing around with the Steam Link Feature in steam. well it adds some audio drivers for speakers and sound card and mic to device manager. well dont do it, it will make your NDI camera App/Virtual Input in NDI Tools NOT work, took me a few days to figure that out. I have found that many side programs like Asus Sonic Radar and others will just totally screw it up. Must be some audio driver conflict. well have a great day.

Newbie Question: NDI for OBS on the Mac

Par seth@sethgo
Apologies if this is in the wrong place.

saw a video tutorial of how powerful NDI is as a bridge between Zoom conferencing and OBS on the Mac.

Downloaded all the tools from your site, but really and truly need a simple one pager--install this, click that, activate the other thing.

Been a mac user since 1983 (!) but I'm flummoxed about what I'm not seeing.

Thanks to anyone who can point me to the right place.

Appreciate it!

NDI Bitrate madness and jitter

Par nomski
Hi All! Hopefully someone here can help with this as we're really keen to embrace NDI for a number of distribution needs when we're broadcasting local sports and events. Essentially the issue is extensive jitter while viewing NDI feeds on our network. After a LOT of testing I think I’ve narrowed it down to only being present when the source PC is connected via a 10Gb port.

If the PC is connected in this way and NDI analysis is run, the average bitrate for the source has been spiking at upwards of 1250Mbps! Whenever that happens (unsurprisingly) the laptops viewing the feed stutter. At times we're getting a stutter at a rate of once every second or two making it pretty unusable even as a confidence monitor.

The issue was originally discovered through vMix but I've used scan converter to rule out vMix as the issue and we're having the same symptoms. If we switch to the 1Gb port on the PC the issue is immediately resolved but I'm concerned with that as I don't want to start to get near the limit of the 1Gb port with all the traffic that goes in and out of that port.

The switch is a Mikrotik CRS328-24P-4S+RM and the port on the PC is a PCIe ASUS XG-C100C. I really can't think of anything else to try and the problem is so repeatable it must be something to do with the 10Gb element.

Is there anything that we can try to resolve this as we would really like to remain on the 10Gb port for maximum headroom as we use a variety of IP based kit and don’t want the 1Gb limit to start to impact on our capabilities.


NDI Studio Monitor Hardware Requirements

Par davdue
I am considering using the studio monitor tool to put a TV at the back of our church sanctuary for people on the stage to reference. It us just far enough away from our presentation computer that we can't use HDMI directly plus we would have to upgrade our HDMI splitters and buy HDMI to Cat5 transmitter receivers. If I can use NDI for this then it would be much easier and economical. I was thinking of using a PC stick for this but I don't know if it will meet the requirements for to run the Studio Monitor application. I am thinking of something like this one: Windows 10 Computer Stick. Would this work? I would really like to use a Raspberry Pi but I can't find anyone that has gotten that to work.

NDI Studio KVM with Touchscreen seems to be buggy

Par FMPstudio
While playing around with the KVM feature i found out, that touches are not pretty well recognized. I tried with different touchscreens and there is a big latency between touch input and execution on the remote system. For example when just draving a rectangle with the mouse selection on the desktop. It works almost fluently while using the mouse as input device. But when touching the screen and doing the same thing it's very laggy.

Another thing is, that scrolling gestures are not beeing recognized. Does anyone else experience similar issues?

Studio Monitor source discovery

Par jgeduldig
Studio monitor shows available sources in its menu. Sources inside the same segment I believe are discovered via a multicast network protocol (mDNS). For sources in other segments -- these are sources that I must add their IP addresses into Access Manager -- does Studio Monitor bypass discovery via mDNS since it already has access to their IP addresses via Access Manager?

NDIHX ios app features?

Par AndersM

I recently bought the Newtek NDI ios app for the second time hoping the new version would be more versatile, but it seems like it has the same limitations as the first one.

With only three fixed resolutions and one fixed frame rate it is very limiting in real production. Other competing apps have all selectable frame rates(including PAL frame rates) and resolutions.
The lack of manual white balance is also limiting.

Any plans to add features to the ios app?


Scan converter not showing up

Par dharris
I've reinstalled NDI tools 4 and on a different computer or tricaster, the machine with the scan converter running does not show up. If I use the NDIAnalysis tool, nothing is there. But, if I run a test pattern from the same machine, that shows up and works. The computer is using and nvidia NVS300 card. Is there something in it's settings that need to be changed? I feel I've tried about everything.


Adding more information.

Using TCPView on the computer, I see when starting up Test Patterns, ports 5353, 5960 and 5961 are being used.
When I start up Scan Converter, TCPView shows port 52595 is temporarily active but nothing establishes and the entries disappear after 2-3 seconds

This unit is running Windows 10 and the firewall is turned off and is on a university domain with remote management. But other computers on the same network are working ok.

NDI Tools 4 - Studio Monitor Switch Source via HTTP Request

NDI Tool Studio Monitor & PTZoptics - Auto Focus issue

Par tbcnj
I purchased a single PTZoptics NDI camera to play with before we replace our entire video setup. Using the "NDI Tools for Windows" I've been able to get a good feel for the network setup and can consume/control the video through the Studio Monitor app. When I turn off auto focus in the Studio Monitor app, however, the camera goes to something of a 'default' focal length, and does not simply keep the current image in focus. I'm trying to determine if this is the Studio Monitor telling the camera to go to a default focal length, or if it is the camera itself sensing that AF is now off and going to a different focal length.

Can anyone shed light on this? Being able to use AF and then disable it in our production flow is very important, so if it is the camera then perhaps I'll have to look at an alternative.


Containing NDI in dedicated VLANs

Par agrosjea
Hello everyone,

With NDI 3.8

We are encountering on several projects an issue that can't be solved without Newtek's insight.
We work on multimedia installations that include many feeds : Dante audio, DMX, sensors... and are used to defining one VLAN per type of feed in order to manage our broadcast domains properly.

The following drawing shows a typical configuration that we use (note that we have most of the time 1x 10Gb adapter dedicated to NDI)

We do want to contain NDI in its own VLAN. This is for a reason : We do not want NDI automatic load-balance to take 100% of the Audio or ArtNET link, leaving nothing behind...
The general question is : how can we control NDI so that it will only use the adapters that we specify (as Dante does) ?

What we already tried :

- We already asked NewTek's support about this and they indicated that access manager could help... but it looks like this tool is not meant for that.
- We tried to understand how the network adapter is elected by playing with the metrics and other type of parameter... no way to understand clearly and that only solves partially the problem.
- We wrote ACL in our switches :
- first version was pretty drastic and was to deny NDI feeds (UDP 5960-5970) on any VLAN other than NDI. It turned to NDI receivers not receiving the feeds anymore : the teaming algorithm seems not resilient enough to consider using an alternate network interface if the connection fails on the selected interface. With these ACL enabled : only the machines that (for an unknown reason) slected the NDI NIC by "default" could receive the feeds.
- we also worked on the discovery itself by denying mDNS on all VLANs except NDI. In this situation, a tool like NDI Analysis tool now clearly lists only IPs in the NDI subnet. But when we do connect the feeds, the "magic" behind NDI makes the feed going again through any of the other VLAN that the sender and receiver have in common... Moreover, no way for us to disable mDNS as a long term solution...

We would like to know :
- For a sender/receiver, is there a secret menu/config-file/network-adapter-naming-convention to tell NDI SDK not to use one or several Network Adapters ?
- If not, is there an official recipe for ACL that we could apply to our network so that NDI is contained in one single VLAN without creating side-effects?
- Could someone share detail about how a complete NDI handshake works (ex : sequence diagram) ? We could maybe have a better understanding of where the sender and receiver agrees on a specific network link to transport a feed ?

Scan Converter crashing!!

Par JCorreia
Recently I've got some problems with the scan converter because it only stays up like 5 seconds and then it shuts automatically with no error or crash note. I've done some research but it seems like no one is having the same issue, at least on Windows machines but I've seen some posts about it on mac.
Any suggestion?

BTW I'm using windows 10 version 1903.

Recommended network topology

Par Meekel
What's the recommended network topology for NDI nowadays? We initially set our network up in a star topology, with our 2 x VMC1 on our core switch, with 20Gb connectivity to each node switch where we would have various other devices plugged in.

We believe it made sense at the time as almost all traffic was going to the VMC1's on the core switch.

I'm now wondering whether it's worth stacking our switches in a ring topology instead?

audio dropping out since NDI4...

I have a TC410 all latest updates and AE3.
I have scan converter running on a pc and need to grab the desktop and audio for a broadcast on Monday but the audio is intermittent.
Been doing this for 2 years without issue and now this.

Why do I need to be a computer engineer to get all this stuff to work?

This happens from any pc with scan converter on to my TC410.
Works fine in studio monitor on any pc on our university network.

any ideas? don't wanna run cables when NDI is supposed to do this...
