audio dropping out since NDI4...

Par rokestah
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...

NDI Tools 4 Access Manager

Par SteveSpaw
We are unable to enter an IP address for remote source in any NDI tools 4 PC.
It worked perfect in 3.8 before upgrades.
If there was a previous address I can edit it, but I cannot create new entries.

This is a big deal.

Help? :question::question::question::stumped:

Hi there,
The Scan converter from NDI Tools 3.8 and 4.0 are not working in the following configuration:

NDI 4 tools on Windows Server 2012 - missing DLL?

Par roddyp
I've got NDI 4 Tools installed on a Windows Server 2012 system, and when I try to start Test Patterns I get a series of three popups saying

"The program can't start because MF.dll is missing from your computer".

Surprisingly, the program does then start!

I also get the same errors when using our own app which uses the NDI SDK DLLs.

Scan Converter Mac cursor tracking issue

Par kelbyadmin
We've run Scan Converter on both Windows and Mac computers (OS Mojave). The mouse tracking seems pretty accurate on the Windows machine, however the cursor tracking on the Mac is way off. Anyone else having this issue?

Premiere Pro Crashes with SPHQ Files and NDI 4

Par rlsafran
I installed NDI 4 this weekend on both of my editing systems. Premiere Pro 19.1.4 (5) and 17.?.? crash when I create a sequence using SPHQ recordings from either a 460 and TC1.

Has anyone else tried this yet?

Scan converter/studio monitor 4 will not display secondary output from laptop

Par SupernovaServer
My goal is to be able to have a graphics machine running powerpoint in presenter view, with the main powerpoint output sending via ndi (in 4k@60) into another computer running resolume (which can take in ndi sources natively).
Currently I am testing this on a Lenovo laptop connected to a 4k monitor or a 4k headless adapter to create the secondary 4k display.
At first, studio monitor was only receiving black. As per a forum recommendation, I set the newtek apps to run on the embedded intel graphics instead of the nvidia 106 0gpu. I was able to pass video at this point, but only the laptop monitor feed. No matter what I tried, the secondary desktop would not show up in the list to view in Studio Monitor.
I did all of this locally on one laptop so as to rule out networking issues, though I did check and the main laptop screen did pass to other computers fine.

Does anyone know how to make this work? If I could send 4k graphics via NDI it would be an amazing option to have on show site.


NDI 4 with Premiere

Par fgolman
Did I recently read somewhere here in the forum that it's possible to use live files that are being recorded on an AE3 system, and growing, in Premiere with NDI 4 tools?

That would be amazing to be able to edit files that are still in production, rather than having to capture them in Premiere or copy a recorded file from the TriCaster upon completion.

Scan Converter Not Working

Par Tek_Soup
well it 1/2 works. It will send the webcam video and audio wich is a elgato camlink 4K, but it will not send the desktop? it shows up but is just blank. really strange, im thinking it has something to do with the intel/nvidia gpu settings. This is a laptop , I have changed settings so it should be mostly useing the nvidia gpu in the Nvidia control panel. win 10 1903 scan converter works fine on all my other computers, Version 4 NDI tools.

IsoCorder download problems.

Par Mark5000
Hi I've been trying to download IsoCorder from the page, but the request button does not respond or times out. (Tried with Firefox and Chome, on several different machines)

Is the two channel IsoCorder available at the moment?
Is anyone else having problems downloading IsoCorder?


Pauses in LW

Par clborrelli
I have the newest MAC PRO and using LightWave v 2015.3 and every time I try to do anything
LightWave pauses. Even if I use v 2018..07 or v 2019.1 they all do it. This has been going
on now for over a week. Has this ever been brought up as a problem ??? Could it be that I
have too many versions of lightwave in my applications folder ??? I only have one open at a
time. and they are very simple scenes.

Has anyone have any ideas on this one ???

SDI inputs on NC1 IN stop working after Windows updates

Par kelbyadmin
Ugggghhh! Everytime a Windows update runs I lose the SDI inputs on our NC1 IN unit. Ultimately, I have to uninstall the last update (sometimes 2-3 updates) before the inputs start working again. Or I have to do a reset to factory in order to get SDI inputs working. This is not only annoying, but a HUGE waste of time!!!!

Is anyone else experiencing this?

NDI 4.0 Scan Converter -> VMC1

Par Meekel
Has anyone tried running Scan Converter from NDI 4.0 Tools and viewing the feed on a VMC? On both of our VMC's it is incredibly laggy. If I view in Studio Monitor on a PC it looks completely fine.

Skype/Zoom NDI Server Audio Crackling

Par rlsafran
Haven’t used my Zoom/Skype servers since NDI 3.8 came out. I’m hearing a crackling noise each time the remote caller starts to speak in my 460 and TC1 recordings. I have two different Windows 10 computers running Zoom/Skype using NDI Scan Converter/Virtual Input and they both have the issue. It’s happening connected to a 460 or TC1. The local Zoom/Skype server recordings are clean.

I’ve tried setting the VB-Audio In/Out, Speaker and NewTek line to 48kHz and 44.1kHz, no change.
I downloaded NDI 4.0 and it looks like it’s not currently available as the download file was still NDI 3.8.

Any ideas? I’ll upload a sample audio clip later this afternoon.

NDI 4 Tools not opening Win 10

Par mannye2003
Anyone else having issues opening the executables for NDI 4 Tools in Windows 10?


Par jkerry211
It the new NDI 4 to some item only on Windows 10 or can Windows 7 use all the available features. I remember the 3.8 some things did not work on Windows 7.

This also may seem unknown, but can I load NDI4 onto the TriCaster system itself?


Scan Converter 3.8 not showing 2nd display as a source

Par dwallace
We run NDI Scan Converter at our church to send the screen displays to our recording system, but something changed ( Windows Patch or Driver update ) and now it will only send the "primary" display as a source. I've updated to the new 4.0 version and have switched the video connections around ( original: DVI on NVIDIA card - primary, HDMI onboard - secondary ... to ... HDMI onboard - primary, DVI on NVIDIA - secondary ) and it will only send the Primary connection.

If I remove the primary display cable boot with the secondary as the only display and then reconnect after it is booted it will send both sources but upon reboot it all goes back to the same.

Any suggestions.

NDI Receiver on iOS

I'm looking to develop a NDI receiver app for iOS. Is it now possible? Has decode support been added to the iOS SDK?
I found the following app - - which let me think that this is now possible.

Thank you,

NDI Studio Monitor - Recording Function

Par RockNRollGeek
Is there more info about this function anywhere? I noticed that it drops recordings into the users default Videos folder on windows, Is there a way to configure the location these recordings go in to? (ie: If I need them to not go on the system drive and instead go onto a second hard drive that is more spacious and dedicated for recordings and things, etc).

I'm guessing there are no quality settings to be configured since its likely just a straight 1:1 dump of the ndi feed into a file right?

Unable to install 4.0

Par Footballer
I have used NDI tools for several years now and I have never had a problem installing any version. 4.0 is making me a little crazy. I have installed and deleted this several times, restarted computer several times. Upgraded nVidia drivers to the latest.

After installing I can click on the app and it looks like it is trying to start with a small spinning circle which disappears after a few seconds. Task manager shows nothing is happening. Windows 10 Geforce 1060

I would be grateful for any suggestions to try?

VLC SyncPlay and Tools 3.8

Par SteveRother
a while back you gave us SyncPlay, an icon on desktop and you could just drop the files into it and they would play repeatedly. Really awesome! I updated VLC to 3.0.8 and I lost everything. I reinstalled Tools Version 3.8 and although it does play it will only play once. I have the player set to repeat but what happens is that the video turns to a green screen after one playing but the audio still gets through. The video is still playing in the player but it greenon the screen. I went to put back the older versions but found a strange thing. I have two versions or Tools 3.8. They are different sizes. I am confused now. Help is appreciated.

Panasonic HN-130 best camera settings for NDI to Tricaster 1080 project

Par DStoneburner
I just got 3 new HN-130 cameras. I stream a lot of events and it's preferred to stream 1080 30p from my Tricaster 8000, so I run 1080 projects, which should be 1080i. I have a TP-Link recommended switch. I'm just trying to figure out the best settings for the cameras. Originally I was 1080 59.94 but I started to get stuttering, so I changed to 29.97p, which seemed to be smoother on camera movements. Anybody have any suggestions for settings on the camera and maybe the switch? Thank you in advance.

NDI PTZO cameras with Tricaster Mini

Par davidcbny
While we've used a Tricaster system for many years, I'm somewhat new to the NDI realm.

We have a new Tricaster Mini and PTZO NDI cameras. All firmware is updated. My TC Mini is set for HD (59.94), and so are the cameras (option B). Everything is ethernet (power, control, video). I get jittery video with any significant movement by the camera or object. Anything I should try? Thanks all. David

Isocorder Free No Audio Monitoring

Par inosit

Recently I installed IsoCorder Free on my pc to test with recording via NDI. The program works totally fine, but I don't hear any audio whilst it does record the audio.
Is there anything I've missed or can try so that the audio monitoring does work?



NDI plugin for OBS

Par draftpunk
I have a question about lan connection between two PC for streaming.
I made giga lan connection and when i stream 2k video on youtube using second PC there is variable lan load, that cause some quality problems on video stream.
There is separate LAN between PC with two giga network cards only for OBS.
So, question sounds like this:
Can I make a connection between two clients OBS with NDI plugins constant?
Now i see LAN load 40-200 mbit/s, but can i make constant 200 or 300 mbit/s between thoose OBS clients to improve video quality?
Can somebody help me with this?
