NDI Screen Capture on Hyper-V system

Par : ChrisO
I have a Hyper-V system running windows 10. The purpose is to screen capture the desktop where we have powerpoint running to bring our deck into the tricaster. It works fine when you first log in, but when you exit the remote desktop app then bring it back up the video stop rendering (its using the microsoft basic render driver). The audio still works but you only get a black image.

As soon as you restart the VM it works again.

Any ideas would be greatly appreciated, thank you

Apple M1 Chip Compatability

Par : Sliver46
Does anyone know if the new Macs are compatible with NDI? Just wondering before I decide to make an upgrade.

iPhone NDI Camera Capture Camera Switching Between Lenses?

Hello NewTek Team (and everybody else reading),

I just discovered your NDI app on iPhone and it's awesome to be able to use this in OBS Studio as a source with audio and everything. I also love the fact that you are actively developing it and making improvements.

I am using the latest iPhone 11 Pro Max with 3 back cameras and one front camera and would like to request the possibility to switch between the back cameras.

1) Switch between back cameras (most iPhones have 2, the latest 11 Pro have 3)
2) Make "speed meter" clearer to indicate which resolution is being broadcasted (I feel the simple speed metering is a bit unclear and if I would not have found out about what it means on a support article here, I would have not known.
3) a way to "center" the exposure dial (in most applications I know, simply double tapping something like the exposure dial would recenter it there, that'd make the use a bit easier).

Other than that, thank you again for providing this and I look forward to these (and other) updates.

To be clear, the most important question is about #1 here and the option to be able to switch between the back cameras of the iPhone which has 3 on the iPhone 11 and 12 Pro versions.

Thanks again,


Scan Converter Missing??


I've just downloaded NDI Tools for Windows to have a play with. I can't see Scan Converter.

I've tried full installs on two computers, both from separate downloads, but I get the same list of programmes on both - neither has SC.

What am I doing wrong? Is it a separate download? Do I need to be connected to a network? Or an external monitor?

How do the NDI PTZ camera's compare to others in the market

Par : ryzen6652
Hey guys,

I just wanted to hear about peoples experience with the Newtek NDI PTZ camera's.
I mostly see people either with the Panasonic AW-HE130 or just generic Dannovo OEM camera's.
I wonder where do the Newtek camera's fit between, in terms of quality.

I found out that the Chinese OEM Dannovo builds the PTZ cameras for a whole lot of brands like ptz optics and huddle cam and many more.
I already have one of these oem brands, and i would like to upgrade to something more high end.
Only connector i use is the UTP for NDI + Poe.

Panasonic is of course a leader in the field but i would like something a bit of not the standard camera everyone chooses. Its more fun.
So the Newtek camera's look cool but after seeing the Marshall CV730-NDI & CV630-NDI who are almost exact like for like the newtek 4k camera's i'm afraid that they are just again common OEM.
Maybe from the same factory as i have now.

Anyone got detailed experience with these camera's compared to Sony or preferably Panasonic?
As guys who brought the NDI to market i would love to have there camera's if they match up.

Thanks in advance

NDI Tools versioning

Par : clking
When NDI Tools 4.5 was released earlier this year, I received the email with the announcement and promptly downloaded what was available. We've been using those downloads for some time now to distribute on Windows and macOS machines in our studios. I have had great success, and great failures with NDI Tools since then.

Just the other day (after a great failure) I went and downloaded them again, both Windows and macOS. The files that came down this time are of different sizes, which would lead me to believe that something has changed, possibly there have been some updates.

On Windows, if I drill down to the executable files after installation, it looks like the current version is 4.5.3.

I appreciate making these utilities available freely to the community but it would also be nice if minor updates were announced similarly to the way the major updates have and a changelog were made available for those updates. This kind of transparency would help this community greatly. I would also welcome a utility that alerted me to updates that gave me the option to download the latest version, but I would take the first option if I can get it.

NDI Virtual Input frame rate

Par : bendenoz

Recently started experimenting with the NDI tools, and the world of NDI :)
I was just wondering if there is a way to set the framerate of the NDI virtual input on Windows? It seems to be fixed at 29.97 fps, whatever the source (I'm trying to do 25fps)


NDI Connect SDI output freeze

Par : kgoodyer
I have a repeatable issue with NDI Connect freezing on JUST the SDI output on DeckLink Duo 2. Input = NDI 1080p50 Output 1080i50 I am using NDI Connect to convert my 50 progressive to 50 interlace. This works perfectly, displaying the NDI stream perfectly within NDI Connect UI and producing a perfect 50i signal on the SDI output.

However if the NDI input stream fails for any reason (Bad WiFi connection, cable unplugged etc.), NDI Connect will recover as soon as signal is reliable again, and displays the NDI stream perfectly within the NDI Connect UI, but the SDI output on the DeckLink card freezes. In truth the stream does recover on the SDI output, and freezes after about 25 fields (500ms) after uptake.

I have set up a similar tool chain using a special build of FFMPEG that support NDI and Decklink and don't have the issue. I have also installed a copy of vMix to also perform the same task, and again it works perfectly. So seems to be an issue with NDI Connect and not the NDI or Decklink API's generally as they are used in both ffmpeg and vMix.

I would love to use NDI Connect, and was 30 seconds away from buying two copies of NDI Connect Pro, but this has scared me off.

In full disclosure my NDI sources are a mixture of h.264 SRT and RTMP streams that have been converted to NDI. Sometimes these remote streams error and drop out (its the way of the internet) the SRT/RTMP and h.264 briefly stops decoding and suspends h.264 decoding and outputting its NDI feed. When the remote feed recovers, h.264 decoding resumes, and all other devices consuming the NDI feed recover perfectly, even NDI connect, its just its SDI output through the DeckLink card that freezes approximately half a second after NDI Connect re-aquires the stream.

Any Thoughts?


POE Touch Screen Monitor with NDI?

Par : CaseyScalf
I know this might be a unicorn of a product but has anyone ever found a touch screen monitor that only uses 1 cable?

Such a monitor would be powered over POE, send video using NDI, and of course have touch screen capabilities built in through that same cable.

I know that might be a lot to ask but lets go ahead and throw in the additional spec of 1920 x 1080 for good measure.

Has anyone ever seen a product like this... yet?


NDI audio dropping on AWS instance

Par : SalGarza
Experiencing periodic (very frequent) audio drops on NDI sources on a couple of AWS g4dn.4xlarge instances running Win Server. Latest NDI tools. During troubleshooting noticed NDI Test pattern app w/tone and Studio Monitor running on same instance also exhibits the intermittent/periodic audio drop. So it appears to be a local issue and not network related. Any clues as to what may be the issue? These instances are being used to run vMix. We’ve had to resort to SRT and/or vMixCall to get reliable video and audio streams across instances. Even NDI Scan Converter -> Virtual Input on same instance (non-vMix) will exhibit the audio drops.

Thanks for your help!


Is my Mac sending NDI?

Par : MarHar

I’m a new user of NDI. My setup is a Mevo start camera using the NDI protocol and a Mac. Our streaming studio is situated in a shared office space. I quickly understood that the NDI video feed from the camera was broadcasted on our shared internet and even ended up on the Wifi. I’m concerned anyone can pick up the signal or at least that it’s consuming bandwidth for everyone.

Therefore, I connected the NDI camera and the Mac (using a USB-ethernet-dongle) to a separate router.

Then I connected the same Mac to Internet using another USB-ethernet-dongle. So, two different networking cards in the Mac. And it worked…I could use the NDI camera as an input in Zoom, using the NDI Virtual Input app.

To confirm I couldn’t connect to the NDI camera from the shared internet, I set up another Mac (the test computer) with the NDI Virtual Input app. As expected, the test computer couldn’t see the Mevo camera as a source when it was connected to the shared internet.

However, my computer was a selectable source in the test computer’s NDI Virtual Input app…with the name “My computer name.local”. But when I selected that as a source, no video was feeded. If I quitted the NDI virtual app on my computer, it disappeared as a source in the test computer.

Then to my questions…

Is my Mac sending NDI in any way?

Is this consuming bandwidth?

Are there any security concerns here?

Do you recommend another setup?

Thanks in advance and greetings from Sweden :)

NDI fails to install on Win 10 Pro

Par : icampion
I am a complete newcomer to NDI and want to use it on a laptop running Win 10 Pro but it won't install. It hangs at the 'Update .NET framework' step. Task manager shows no CPU activity and static memeory usage. The cancel button does not respond, so I have to end the task. I have tried with virus checker (Kaspersky) switched off, again no success.

I have installed successfully on two Win 10 Home machines, so it seems to be version specific. All windows updates have been applied to all machines. The only other obvious difference is that the Pro machine has significantly more apps installed and running at startup.

Any suggestions welcome, though I'd prefer toavoid uninstalling loads of apps and reinstalling them!

No NDI on same machine - Troubleshooting tips?

Par : simond83
I have a master image that I've built that works (Server2019) and is running in APAC and AMER. It's deployed within Google Cloud. I've built a new machine in London and deployed the same image as before. Now, I can't get any NDI signal at all...not even locally from the test pattern generator on the same machine and it's driving me mad!

For some reason, deploying this image in a different data center has had a few settings change in the image. It had turned back to Public rather than Private network. I've checked DNS, Function, SSDP and UPnP etc. All good. I'm using the Discovery Service and have checked the firewall, but that's not really going to affect things, as this issue is local to the machine and image (ping works etc).

I did notice that in Device Manager, there were 'Hidden Devices', so where i'd built the image in 1 datacenter, deploying it in another had detected a new NIC. This meant that i'd connected via Network 2 or Network 3, rather than just Network. Fixed all that by removing hidden devices in Device Manager. I'm running out of ideas here?! What else can i trouble shoot to try getting NDI working locally. Test Pattern Generator to Studio Monitor doesn't work at all. I've already tried reinstalling NDI tools with no luck. OBS can't see the NDI signal either.

Le Creative Cloud se met à jour : quoi de neuf et quelles pistes pour l’avenir ?

Par : Shadows

Adobe a profité de sa conférence Adobe Max pour mettre à jour son Creative Cloud.

Voici les avancées que nous avons retenues :

  • la possibilité de streamer en direct depuis Photoshop sur iPad, Illustrator sur iPad et Adobe Fresco : une bonne idée pour présenter ses talents et proposer des formations.
    Si l’on aurait aimé un lancement simultané du streaming sur desktop, Adobe y pense et a même lancé une version beta. Il est possible de demander un accès à cette fonction.
  • Une série de filtres Photoshop s’appuyant sur l’intelligence artificielle ont été dévoilés. Remplacement de ciel, ajustement de l’orientation d’un visage, ajustement de l’éclairage, suppression d’artefacts jpeg, colorisation de photos noir et blanc… Les outils sont nombreux, et il sera évidemment intéressant d’en tester les limites et possibilités.
    A noter, la fonction Smart Portrait s’appuie sur des technologies NVIDIA, et plus précisément StyleGAN2.
  • Plus de 3D dans After Effects : Adobe dévoile une série d’outils pour travailler rapidement et efficacement dans l’espace 3D : gizmos, outils de caméra, nouveau plan pour le sol…
  • Adobe a aussi profité de sa conférence pour proposer quelques aperçus technologiques, qui pourraient à terme arriver dans ses produits. Au menu :
    – Sharp Shot, avec de l’intelligence artificielle pour améliorer les vidéos qui manquent de stabilité :

-2D Plus, des outils 2,5D pour Illustrator :

-Scantastic, un système intuitif de scan 3D :

-In Sync, qui vise à améliorer l’usage des fichiers XD :

-Typographic Brushes, qui sera utile pour la création de typographies personnalisées :

-Material World, un workflow simple et intuitif de création de textures :

-On the beat, pour synchroniser musique et vidéo :

-Physics Whiz, une approche physique et intuitive du layout 3D :

-AR Together mêle réalité augmentée et collaboration :

-Comic Blast, enfin, vise à accélérer la création de bandes dessinées.

Pour une version plus exhaustive des annonces Adobe, on se rendra sur le site de l’éditeur.

Isolate audio from an NDI camera, to apply across all cameras (OBS)

Par : Michael B
Hi. Simple setup: 2 NDI cameras, one (CAM1) has mixed audio coming through it (literally, via a jack on the back of the camera). I want that camera's audio running in my production continuously, regardless of which camera I have selected as a source in OBS. My current hack is 'hiding' the CAM1 source behind the CAM2 source in my CAM2-based scenes, thus, CAM1's audio is always available. This accomplishes what I want, but I'm wondering if there's a way to split or reference CAM1's audio stream (only the audio component) to include in the CAM2 scenes.

My mental model is based on USB webcams which present separate video and audio streams that can be used independently.

Thanks in advance.

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.

DxO PhotoLab 4 en test : un lancement qui va faire du bruit

Par : Shadows

Le spécialiste des solutions photo DxO lance la version 4 de PhotoLab, son logiciel de traitement d’images, avec une annonce qui mérite le détour.

La mise à jour apporte différentes avancées :

  • un espace de travail paramétrable par type de correction, système de favoris, corrections actives : parfait pour retrouver facilement les éléments importants ;
  • une nouvelle fonction recherche qui se veut assez ouverte : si vous venez d’une solution concurrente comme Lightroom, par exemple, vous pourrez trouver une fonction via son nom dans Lightroom ou dans PhotoLab. De quoi sauter le pas plus facilement ;
  • le renommage par lots d’images ;
  • un système de copier-coller sélectif des corrections (qui fait penser à ce que propose déjà Lightroom) ;
  • un historique avancé, qui liste les corrections et permet de les modifier ;
  • un watermarking plus facile, avec prévisualisation directe et possibilité d’inclure image, texte en simultané.

Autant de nouveautés certes intéressantes, mais qui sont selon nous largement éclipsées par LA grande avancée de cette version 4 : DxO DeepPRIME.

DeepPRIME : des millions d’images au service de vos photos

Le concept de DxO DeepPRIME part d’un constat : depuis son lancement en 2003, DxO a testé une grande quantité d’appareils photos et d’objectifs, notamment en mesurant le bruit numérique dans diverses situations. Le résultat est une base de millions de photos calibrées.
D’où une idée : utiliser ce stock immense de références pour corriger d’autres photos, prises avec des combinaisons boîtier/optique déjà mesurées par DxO.

C’est ce que propose DxO DeepPRIME, via l’intelligence artificielle et le deep learning, en assurant simultanément le dématriçage (la génération de l’image à partir des données brutes issues du capteur de l’appareil photo) et le débruitage. Selon DxO, effectuer les deux opérations en même temps évite d’introduire certains artefacts et produit de meilleurs résultats.

A la clé, selon DxO : un gain de qualité équivalent à deux stops de sensibilité ISO. Reste à vérifier les promesses marketing dans la réalité.

Comparatif DxO

DeepPRIME en test

Et puisque les promesses sont grandes, nous avons immédiatement choisi un test difficile : un cliché pris lors d’une visite de la partie accessible au public des catacombes de Paris. 1/40s, f/4.0 et ISO 25 600 : le cliché brut est sans surprise très bruité. Lightroom permet d’éliminer le bruit mais nécessite de nombreux ajustements : il s’agit de trouver un bon équilibre entre correction et effet artificiel. DxO DeepPRIME nous surprend immédiatement : le mode automatique propose un résultat propre, qui retrouve en prime des détails quasiment noyés dans le bruit d’origine. Impressionnant.

Second essai avec un autre appareil, plus ancien : un pensionnaire de la ménagerie du Jardin des Plantes, pris au 7D à f/4.0, 1/60s, ISO 6400.
Nous avions eu du mal à corriger sous Lightroom (en haut) : DxO DeepPRIME (en bas) retrouve nettement plus de détails, que ce soit sur les yeux (qui retrouvent leur couleur), les paupières, le pelage.

Encore un exemple, à ISO 8000, sur un cliché que nous avons pris lors de l’incendie de Notre-Dame : là où nous arrivons à éliminer le bruit sous Lightroom (haut) au prix d’un rendu délavé, DxO Prime nous donne immédiatement un résultat détaillé.

La différence est encore plus flagrante en recadrant davantage (DeepPRIME est en bas), notamment sur les blocs de pierre. L’échafaudage est défini plus clairement.

Sans vous assommer de comparatifs, plusieurs essais avec des situations variées (portrait en basse lumière lors de conférence, macro sans flash, photos d’objets à la texture détaillée pris dans des musées…) nous confirment que DxO DeepPRIME donne de très bons résultats.

Certaines personnes objecteront que le problème se situe peut-être entre la chaise et le clavier, et elles n’auront pas forcément tort : nous ne prétendons pas maîtriser parfaitement les subtilités du débruitage sous Lightroom, qui comporte pas moins de 6 curseurs d’ajustement.

Et justement, nous y voyons un argument supplémentaire, pour ne pas dire l’argument principal, en faveur de DxO Prime : remplacer l’apprentissage d’un système de débruitage par un simple clic et une correction automatique est une amélioration énorme, même à qualité identique. Nous ne pouvons donc que vous inviter, si votre style de photo vous amène régulièrement à faire face au bruit numérique, à tester ce produit par vous-même.

Bien entendu, DxO Prime n’est pas parfait : si la combinaison boîtier/objectif n’a pas été testée, l’outil cherchera à débruiter l’image mais ne pourra pas donner un résultat aussi bon. D’où l’intérêt de vérifier que votre matériel est supporté.
Un bon moyen de le savoir est tout simplement de parcourir vos dossiers photo via DxO Photolab : le logiciel propose de télécharger un module optique (qui gère notamment la correction des défauts optiques) si la combinaison boîtier/objectif est connue, et affiche un point d’exclamation sinon.

Notez qu’il est possible d’opter pour un téléchargement automatique de ces modules, semi-manuel (le logiciel demande confirmation avant chaque téléchargement), ou totalement manuel : DxO Photolab propose un installeur de modules. Ce dernier s’avère particulièrement utile pour vérifier en un clin d’oeil les combinaisons compatibles.

Un outil perfectible ?

Un regret pour finir : les performances. Comme l’indique DxO lui-même lors du choix de la technique de débruitage, DeepPRIME est nettement plus long à calculer le résultat que les approches déjà proposées jusqu’ici (et qui restent incluses dans l’outil). Conséquence : impossible de disposer d’un aperçu sur toute l’image dans DxO Prime, il faudra vous contenter de la loupe. De même, le temps d’export des images est nettement plus élevé : +44% environ par rapport à l’option de débruitage « PRIME » du même logiciel. L’enjeu pour une prochaine version sera donc sans doute d’améliorer le temps de traitement.

Iso corder

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

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?
