Options for camera inputs

Par : KRTW
Greetings. I still have much to learn, but my experience with NDI thus far is more than favorable. I find myself, during these difficult times landing more and more professional gigs for filming and streaming. I cannot afford to have a catastrophic loss, and the bottle neck is my capture devices. Currently I am using Blackmagic Quad in one machine, and a Quad 2 in another machine....the Quad 2 no longer runs properly - 4 inputs don't work. The cost/channel on this device to replace it new is $215/channel. But its old technology now.

I run only at 1920x1080 and see no reason to move to 4k for the foreseeable future as all of this is for streaming.

Here is what I think, and I may be wrong. I believe that I could run 8 cameras into HDMI to NDI converters, run all of these into a GB switch, and hook my Vmix rig up to the switch, and get 8 inputs. The question is at what cost.

Some of these stand alone converters are $800 each in my dollars, so for me, I cannot afford this. That's 4 times the cost of the Blackmagic unit.

Is there something out there that has at least 8 HDMI inputs, and can convert to NDI at a lower than $800/channel cost?
Is my belief that this is even possible via a GB switch?

Any help/feedback or direction most appreciated.

I need to learn how to spell Inputs....noticed after posting and can't edit the Thread title.....sigh.

Hi, question plz

Is ISO corder pro discontinued?

transmission problems over wifi

Par : jpenns
I have a wired computer that is livestreaming from OBS to Facebook. I'm simultaneously sending that video signal over NDI (using the OBS plugin) to a wireless laptop, and displaying the video on that laptop using NDI Monitor. I find that the video transmission is very spotty over wifi, which is understandable, except that the wireless laptop can stream the video directly from Facebook without issue. I would much rather receive the signal directly over my network rather than get it through Facebook. Is there any way to improve the video transmission? I'm already using the "low bandwidth" option in the NDI monitor software.

Can I re-route NDI audio channels (3&4 > 1&2) from Tricaster

Par : boyler
Hello,

If I have an NDI stream with video and 4 channels of audio, can I create a new NDI video stream using channels 3&4 from the source NDI stream?

In other words, I want to put channels 3&4 from one NDI stream and put them into channels 1&2 (aka Left and Right stereo feed) in a second new NDI stream.

Is this possible?

NDI Scan Converter can‘t capture Applications

Par : LANDWEHR
Hello everyone,

I tried using Scan Converter to capture a specific Application but somehow there is not a single application I can choose in the Settings. I can only select a Region of Interest or the whole screen.

Anyone got an idea of why this happens to me ? Would be very pleased if anyone can help me :).

Kind Regards

Remotecontrol of NDI Virtual Input

Par : cd-tronic
Hi,

does anybody know if it's possible to remote control NDI Virtual Input?

Background: I'm using NDI Virtual Input to view the Camera Input on a Digital Signage System. This works great.
Now we plan to add a second Camera to the System but i only have one Virtual Input Device. That's why i need to remotely change the input device (rightclick -> select input).

I thought about using an auto Hotkey script that i can trigger using an TCP / powershell command. But it would be better to use some kind of direct API for this.

Any idea?

Regards,

NDI Scan converter

Par : Jmcnally
I'm trying to run a Mac Keynote program through Scan Converter. On one computer (OS 10.14.6) I have SC running and I can see all the programs open and available to SC. On my other Mac (OS 10.15.7) I have SC open and only see a connection for Windows Server but nothing for the Keynote program that I need to connect with. Is there a limitation of SC working with 10.15.7 or is there another step to allow Keynote to become visible to SC?

thanks,

NDI PTZ camera and no video input

I have a Minrray PTZ NDI camera that I had set up here at my office in Arkansas and had it working fine.

I shipped the camera and a laptop to a client in California. Tthe laptop has both Studio Monitor and VT-Publisher.

1. My client hocked it up in two different locations.

2. when it connects to the network we it set as a private network.

3. both times Studio Monitor can "see" the camera as a NDI source, you click on it and no video, no controls show up.

4. When I turn on another program, VT-Publisher it sees the camera as an NDI source, and scans for the NDI signal and never gets it.

5. When I tried to have a small network with only the camera and the laptop as best I remember did not see it on the network.

6. When I connect a HDMI cable to the camera we get video.

Ideally I am trying to get this program VT Publisher to recognize the camera and then I can send that signal to me here in Arkansas and control it from here.

I have team viewer on that laptop.

Willing to pay someone to help me trouble shoot this. I have an event I am supposed to use it for tomorrow Oct. 12.

Thanks, James

OS X NewTek NDI Scan Converter - No Preferences?

Par : ethanopp
Hi All,

I am trying to get an NDI feed (audio and video sources) sent from my macbook pro to desktop PC (running OBS).

Right now I am able to get NewTek NDI Scan Converter set up, but the feed is a little choppy? It seems like the framerate may be set to low, but when I try to update the preferences its greyed out:

Is there a way I can play with settings on OS X?

If not, is there another tool I should be using to send NDI feed?

Thanks!

NDI & NDI HX comparison and capabilities

Par : PascalN
Hello,

i have spent some time searching for it now...but unfortunately i can't find anything.

I would like to know if there is an overview of what NDI and NDI HX are able to do.
I am especially interested in whether NDI HX is able to transmit 4k 60p like NDI.
I would like to use 6 NDI HX cameras:
4x Panasonic AG-CX350
2x Sony SRG-X120
These should be cut with a vMix Station and then the output should be sent to a second vMix Station via NDI.

I was told that NDI and NDI HX sources cannot be used together or there is a general incompatibility. Can someone confirm this or is someone using it anyway?

I would be very happy about some answers or tips!

Best Regards
Pascal

NDI tally delay

We are experiencing enormous tally delays on all NDI cameras and converters from different manufactures. It takes at least 1 second for the tally to turn on and way more than 1 second for a tally to turn off.

On the multiviewer and on none-NDI-tallys it is perfectly fine.
The delay itself is bad, but different delays for on and off is even worse. With this behavior it is impossible for our host to follow tally.

I made a video to show the effect: https://youtu.be/W-QiQAyxVM4
All cameras are connected via wired NDI and PTZ Camera 3 additionally via Ethernet Control to show, that this way works instantly. Even the full NDI signal over wifi to a Studio Monitor app is much faster.

Our setup:
TriCaster TC-1 on a standalone gigabit network with D-Link switches
(The internal delay from cameras to PGM is around 6 frms)

Is this normal or is there a way to address the this? Is this even an NDI issue or maybe something else cause this?
Thank you for you support :)

CPU with AVX Instructions

Par : ronsatter
I have a problem installing any NDI Connect software ... even the free Connect version.

I am trying to install on PCs running Windows 10 Home.

What does this message mead? ( NewTek Connect requires a CPU with AVX instructions )

Do I need a special CPU ??

RoI is disabled when computer restarts

Par : Laburete
I am using the NDI tools to capture an area of the screen and use it as a virtual camera in a Chrome window, the problem that I have seen is that sometimes the Region of Interest is disabled after a reboot and the whole screen is captured. Has anyone come across this? is there any settings file that can be defined?
Thanks in advance.

Release notes

Is there a document that lists fixes and other changes between versions of NDI SDK and NDI Tools?

Unable to connect my phone to Virtual Input

Par : Nic Dr
I have the newest versions on both Virtual Input on PC and NDI HX Camera on my iPhone 7. Virtual Input can't find my phone when i use the camera app on my phone, it says: " No NDI sources found."
I used this app in june for school and worked perfectly fine and now it can't seem to work, also for school.
Thanks!

Unable to load kernel driver (video)

Par : tomgo
Hi,

I have used NDI Tools (specifically NDI Virtual Input) for a while now on my old laptop under Windows 10 Enterprise Version 1909.

Since last week I have a new laptop (Microsoft Surface Book 3) which had Windows 10 Version 2004 preinstalled. I have change the license to Enterprise and installed all latest updates. Then I ran a script from my companies IT admins which was basically installing a virus scanner and made some basic settings like mounting common shares.

When I install the latest NDI Tools 4.5 now (just downloaded few days ago) everything looks good first (no error messages). But when I start NDI Virtual Input then (same behavior with or without reboot) I get the following error message.

In the UEFI menu I have disabled secure boot completely (no change). Also, I have put the OS into kernel driver test signing mode (no change). I reinstalled NDI Tools several times under these different conditions (no change).

I wonder if this is a known issue. It looks to me that there is something different on my machine which "NDI Virtual Input.exe" is not able to deal with. All other hardware drivers are working completely fine, so it might not be a general problem.

Can somebody perhaps tell me what exactly is the condition which is causing this error message?

Install failure

Par : KRTW
Hi. NDI is fantastic technology and I hope I can get this working.....I've installed thousands of programs and never seen anything like this. So I signed up, got my link, did the download, ran this install and everything seemed to go well. THen I started the app NDI Studio, and it started the install program for my Yamaha ASIO drivers.....yup. Starting the program ran a program to install Yamaha ASIO drivers, that are already installed....first time I just cancelled the install, but it would not shut down....So I rebooted and tried again....but the install program was still running so I had to power off and remove the battery....then I tried to run the NDI Studio again, and the install started....there were error messages and the install ran forever....I had a show to run, so again shutdown, powered off and gave up.

Any ideas here?

NDI Access Manager - discovery service

Par : herlsone
Is there more detail on how these tools work? I see access manager stores data in a appuser roaming xml file. But it does not store the discovery server data in that file and I cannot find another location of data being stored.

If you use discovery service, does it completely ignore the output and receive groups?
What defaults are needed in groups?
If discover server is enabled are any ports needed to be forwarded at all? or can all machines now see and receive what the server is keeping track of?

Any tutorial at all??

Thanks

Scan converter - region of interest displaying green bars when taken as input

Par : hypohamish
So, best way I can show this is with a GIF

https://i.imgur.com/P33irQK.mp4

I have scan converter set up on a laptop to capture a region of interest (screenshared powerpoint from zoom)

I'm taking that as an input over NDI into Vmix - but when received into Vmix, I see these weird little green bars. The bars move/change shape when I resize the ROI on the laptop.

They do not however appear at all on the laptop or at any point with configuring the ROI.


Is this an NDI/Scan converter issue, or is it a Vmix one? A colleague with the exact same setup doesn't experience this.

MacBook issues sending Keynote with video backgrounds

Par : highab
Hi,
We have an all-mac system. We've been using it OK for 6 months now.

I have, however had to be creative in sending a keynote from a macbook pro 2012 to the network, yes it's old but we tried the same file with a newer macbook and still things didn't work quite right.

We've been using VmixDesktop capture of Display 2 over the network without problems for our iMacs and MacMini since showing screen 2 of a MacBook Pro via NDI scan converter seems impossible since to select Keynote screen 2, Keynote screen 2 needs to be activated and if it's activated then keynote blocks us from going into NDI scan converter and selecting the feed to be sent or making any changes to the quality of the feed.

When we tried a macbook with VmixDesktop capture of a file with a video background we did have output BUT:


1) The slide shown via HDMI and the slide shown via NDI were not always the same and sometimes took forever to catch up
2) The background video stuttered, it wasn't nice and smooth as it should be.

I have been doing tests with a different laptop mac that doesn't have much RAM at the moment. Even if I remove the background video from the Keynote file and play just the background video using QuickTime player, it plays properly, waits a bit and then plays again, it's never a smooth feed, whereas playing something on YouTube and showing it over NDI seems to work without any problems, proving that the NDI feed can work.

So although I do have a workaround solution, sending the feed via HDMI into our video switcher and using the feed from the video switcher as the NDI source which then outputs video that is very smooth. I'd really like to understand what the problem is.

I've tried manual ethernet configuration on the 2 tests macbooks, setting it to Jumbo but I don't know what else to try.

The NDI signal taken from the video converter via a BirdDog mini works just fine, so it doesn't look like the problem is the network.

Does anyone have any ideas or point me in the direction of other tests to do to try to work this out?

Many Thanks!

NDI & Sony SRG-X120 - No picture

Par : kadams79
Recently purchased a Sony SRG-X120 to use for live streaming via OBS. I currently have the camera and computer connected via ethernet to a Linksys EA9500 router. The computer is Windows 10 with a Gigabit ethernet port. Camera firmware has been updated, the NDI license has been added to the camera, and it shows as a NDI source in Studio Monitor. Unfortunately there is no picture. I've looked through the forums and Google articles for two days with no luck. Can anyone help me figure out what I'm missing?

NDI 3.0+ Runtime

Par : NightFox
I am looking for this version I need the NDI 3.0+ Runtime PKG for macOS. Does anyone have a copy of this? For I have an older Mac that I am running with max OS 10.11.6 and I would like to have NDI put on it so I can run a i.link or IEEE 1394 Camera. But I having a nightmare of a time trying to find an archival for this program

I would use the new version but it would seem that El Capitan does not work well with any anything above OBS 19.x and that means that only NDI 4.2.2 will work with that version and it needs the NDI 3.0 Runtime.

Any help would be greatly appreciated.

Unless you can help me to understand how to get a new version of OBS to work correctly and will work with the NDI 4.5.1 run time.

One of the problems is related to the fact that with the OBS 24.x, 23.x, 22.x version is that it will either not allow the transition to other scenes or will keep the program screen black. For I see the image in the Preview under studio but when you try to translate it to the program view or streaming view, the screen remains black.


Thank you in Advance

No audio from NDI source in OBS

Par : thomasvt
Not displaying any audio levels on a Win 10Pro laptop. Have checked and do not see any issues with OBS settings.

I have tried from another Win 10 computer and that seems to be working okay. Also tried from Ubuntu laptop and it works okay.

Have run the NDI Analysis tool on the two Win 10 laptops for comparison and the output files are attached.

Is there anything I need to check on the Win 10 laptop to get the NDI audio working. Could it be any firewall or AV which may be filtering audio. Is there anything I need to check on the NDI drivers?

Talkshow 4000 over NDI horribly jittery on a brand-new TC1...

Sorry for the cross-post over in the Talkshow forums, but this is an issue I *have* to get fixed.

Just last week I traded in my TC460 (bye-bye W7) for a TC1. The install went well, everything seemed to be in line, but in testing with our pre-existing Talkshow 4000, it has become pretty obvious that in the path from the TS to the TC1 something is quite unhappy. The video in the TC1 is jittery and wildly out of sync. Luckily I can record the Talkshow signals internally - that saved my butt on a high-profile guest last week on a taped show - but the majority of our shows are live, with from one to four Skype channels in operation.

So: Anyone have any insight? As you might expect, our LAN in the building is basically wide-open, with everyone working at home. In fact, the only variable here is the TC1 - the 460 had no issue with the Talkshow signals.

Is there some "best practice" for the TS4000 and the TC1 I may have overlooked?

Thanks all -

NDI|HX Dropouts and Missing Info in NDI Analysis

Par : CUCMedia
We are experiencing audio dropouts when receiving NDI video from Newteks NDIHX-PTZ1 and PTZ Optics cameras on our corporate network. Dropouts have occurred when receiving video with either Studio Monitor or the Tricaster TC1. In an effort to diagnose the issue we turned to the NDI Analysis app (see attached reports). There both the Newtek and PTZ Optics cameras report using an unknown codec and data rates of zero. The TC1 report looks normal, though the "Video recv" variation is a bit disconcerting. This all brings me to my question:

Is the missing data in the NDI Analysis report a stem from an inability to parse the information from an NDI|HX stream or another symptom of poor network or machine configuration?
