Zoom Server NDI Return to Caller Audio Distorted – Clicks/Drops

Par rlsafran
I use NDI Scan Converter and Virtual Input with VB Cable for Zoom servers. All audio record/playback sources are set to 48 KHz (44.1 doesn’t work either). The audio returned to a Zoom caller is severely distorted with clicks or drops. This has been happening since last year.

Instant Teleseminar’s return to caller is just as severe and a Skype return has less noticeable scratching sounds that occur above 6k intermittently.

I have Zoom engineering working on the issue but am not able to help them replicate it without using a TriCaster as NDI Test Patterns returns perfectly if Zoom “Use Original Audio” is enabled and the client’s mic is muted (I always enable “Use Original Audio”, but the Zoom distortion happens either way).

Instant Teleseminar returns perfect 1 K tone from the TriCaster, but music files (.wav or 48KHz) have the noise.

Anyone else using Zoom or ITS back to a TriCaster? I’ve tried it on four different Zoom server systems with NDI 3.8, 4.0 and 4.1 and it always occurs from both a 460 AE2/3 or a TC1 (where NDI Test Patterns returns perfectly to the caller).

Attached is an audio file demonstrating the audio distortion - clicking/drops. The noise between
0:21 – 0:23 is me handling the headset.

VLC Plugin

Par jaskie
Hi everyone (it's my first post on this forum)!
Recent NDI Tools installations contains VLC plugin, which is working excellently. But there is no additional documentation on it, especially about its configuration and usage. Furthermore, I have found a licence file installed with plugin .dll, which contains GPL licence. If the plugin is really licensed on GPU, its source code should be offered, as the licence states.
Where can I find more info about the plugin, and (maybe) it's source code?
Kind regards,

Une solide mise à jour pour Terragen

Par Shadows

Terragen passe en version 4.4 ; derrière cette numérotation se cachent des avancées majeures.

En effet, le path tracer proposé en interne, jusqu’ici loin d’être finalisé, a gagné en fonctionnalités : il est désormais officiellement présenté comme utilisable en production.
Concrètement, le path tracing supporte les mêmes fonctions que le rendu standard, tout en apportant un gain significatif en réalisme. Les scènes complexes, par exemple avec beaucoup de végétation ou en interieur, sont très largement améliorées.
Mieux encore, le path tracer gagne en vitesse par rapport à la 4.3 grâce à un meilleur échantillonnage et une gestion des ombres plus intelligente.

Outre l’illustration d’en-tête signée Terje Hannisdal, voici quelques cas concrets de rendus réalisés avec le path tracer :

Doug Campbell
Terje Hannisdal
David Guegain

Optimisé par rapport à la 4.3, le Robust Adaptive Sampler devient la méthode d’échantillonnage par défaut. Il devrait améliorer la qualité des rendus dans tous les scénarios nécessitant un échantillonnage poussé, par exemple pour le rendu de nuages.

D’autres avancées sont annoncées ; on retiendra notamment un rendu plus rapide des nuages, une amélioration de l’aperçu raytracé.

Pour la liste complète des améliorations, on consultera le site officiel.

Compressed Audio in NDI

Par jainrajath
Hi,
I was looking at NDI SDK for use in the internal pipeline in a project I'm working on. I had a couple of doubts regarding the audio:
1. Is there any support for transmitting compressed audio formats (like ac3) over NDI? Or does it only support raw frames?
2. How does it send the audio frames? Does it compress it internally or send it as is? If it compresses, is it lossless?

What are the best specs for a Skype PC Laptop running Virtual Input?

Par boyler
Hello all,

I've experienced a bit of a headache today testing 3 different machines with Skype + Virtual Input.

I'm running the NewTek PTZ camera, and using Virtual Input in Skype for the video feed. I am not using the Camera's audio input, and using a separate USB DAC solution.

I've tested two Lenovo Thinkpad's with 16GB of RAM and 2.2 GHZ quad core processors today, both running Windows 10. Both have struggled to broadcast the PTZ Camera while receiving a relatively high quality return feed from the Skype guest.

What I find troubling is that I can run Skype TX on a PC Laptop with less Speed and less RAM, and not have any problems.

If I set the Windows performance settings to BEST, I can run a relatively smooth Skype session. The total CPU percentage runs between 40% - 75%. If I try to open another application or move windows around, forget about it - the Skype session goes haywire. Once there is lag or frame drops in the camera's feed, it is NEVER fixed again. The only solution is to start Skype again.

If I run a Skype session on a Macbook Pro with 16 GB Ram and 2.2 6-core processor, using Video Monitor and Skype's Screen Share feature, it runs flawlessly. (Despite the fact that screen share can only run at about 15 fps.) I'm wondering if I should try Boot Camp on the Macbook Pro.

So my question is - who runs Skype with Virtual Input on a PC laptop, and doesn't experience any of the outlined issues? What your specs?

Many thanks in advance.

EmberGen : “le simulateur de fluides le plus rapide du monde” arrive en alpha

Par Shadows

Nous vous le présentions l’été dernier alors qu’il ne se montrait que sous forme d’aperçus vidéo, le voici désormais disponible en version alpha. EmberGen, proposé par JangaFX, est un simulateur de fluides spécialisé dans le feu, la fumée et les explosions.

Concrètement, EmberGen permet de travailler en temps réel et d’exporter, au choix, flipbooks, séquences d’images et volumes VDB.

L’outil permet de travailler en temps réel et se destine à deux secteurs distincts :
– le jeu vidéo, tout d’abord, via l’export de séquences d’images et flipbooks. Attention, à ce stade aucun export volumétrique pour un usage temps réel n’est implémenté : cette fonction est néanmoins prévue à terme ;
– le cinéma, ensuite. Pour ce domaine, EmberGen permet l’export VDB, PONG, TGA et EXR, selon que vous souhaitiez séquences d’images ou volumes. L’éditeur souligne que sa rapidité peut être un atout en prévisualisation, et que l’outil pourra néanmoins aussi, bien entendu, utilisé pour créer les simulations finales.
A terme, EmberGen devrait proposer davantage de fonctions pour cette industrie, avec par exemple des exports alembic et la gestion des collisions avec des meshes importés.

Compatible AMD et NVIDIA, EmberGen nécessite l’équivalent d’une carte GTX 1060 au minimum.

Le site officiel vous permettra de demander un accès à l’alpha. De quoi vérifier par vous-mêmes si l’affirmation de l’éditeur, selon laquelle son outil est le simulateur de fluides le plus rapide du monde, est belle et bien respectée en pratique.
Notez également que les tarifs finaux du produit sont déjà annoncés.

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.

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

Gaming PC:
2x RTX 2080 Ti's / i9-9900k

NDI over VPN with two Fritz-Boxes

Par MDCommander
Hi.

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: 192.168.178.10) is connected to the FritzBox 1 (IP: 192.168.178.1). This is via VPN tunnel (manufactured by the FritzBox 1 to the other FritzBox 2) with another FritzBox 2 (IP: 192.168.10.1) connected. At the FritzBox 2 is a PC 2 (IP: 192.168.10.20) 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 (192.168.178.1 and 192.168.10.1) 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.

greeting
Markus

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 https://www.newtek.com/software/adobe-creative-cloud/.

(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.
https://community.adobe.com/t5/chara...0760552#M11495

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.

La Cage : identité de genre et déchirure dans un court ECV Animation

Par Shadows

Pour leur projet de Mastère 1 (4è année du cursus ECV Animation), Jin Lan Shi et Wenqing Wang ont réalisé un court-métrage qui traite de dysphorie de genre, au travers d’un personnage tourmenté par la pression de ses proches et de la société.

Ce n’est pas la première fois que ce type de thématique est abordée dans un court de fin d’études ; on repensera notamment au film Les Lèvres Gercées de Fabien Corre et Kelsi Phung, dévoilé dans le cadre de la promotion 2018 des Gobelins.

FULL NDI vs NDI HX

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,

Rob

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.

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.

Thanks!

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?
