Hi Yoram, thank you for the video. By far you are the best presenter about NDI and Zoom. In particular about the different routing and comes with detailed diagrams. I have checked your other video about Beginners with OBS and Zoom. There is one thing that I would like to request you for a answer or a video, that is how do you arrange a side by side interviewer and interviewee on Zoom. It seems NDI can push out audio and video, but how to get audio from an interviewee (Guest Speaker)? Looking forward to hear from you. Much appreciated.

[@DiscipleDojo]

Did this ever get answered? I'm having trouble recording audio from those I interview. I can hear them just fine, but OBS doesn't record their audio, so it's just silence when they speak (which I only find out when I go to edit the video...and is SUPER frustrating).

[@infinite.spaces]

Hi Yoram, I have a similar setup with one additional step. The virtual audio cable is still useful for routing Zoom speaker output back into OBS for the scenario where you want to bring Zoom guests into your stream.

[@YoramSolomon]

YES! Good idea! I didn't uninstall CABLE from my computer after using NDI either.

[@gordonlaroussini1735]

@@YoramSolomon Instead of routing back the virtual cable to OBS, can you just record from Zoom and capture all sound and video?

[@TechforToastmasters]

This works perfectly for me now. I think it's an elegant solution compared to the virtual cables. Yesterday, I had an issue using OBS Virtual camera using CISCO Webex and found it is a know issue. The NDI solution should work for this case.

[@TechforToastmasters]

Just a note. My microphone output is set to 'Monitor Off' but NDI still picks it up. If I set it to 'Monitor and Output', I am actually getting an echo on my desktop speakers. I am wondering if I have made some mistake but I tested it multiple times.

[@YoramSolomon]

Check if you still have cable on...

[@TechforToastmasters]

@@YoramSolomon No. I never installed the virtual cables.

[@RichardsWorld]

I've been experimenting with trying to livestream my Zoom calls on the free version and OBS, to KZbin. The biggest issue is sending out your voice to KZbin, as the audio only goes to the guest. I fixed this by adding a second microphone. Mt guest gets the audio from my cheap microphone, and the Livestream gets the audio from my nice microphone. The livestream comes out well, just got to balance the audio levels.

[@YoramSolomon]

Excellent! I suspect this can only be done with any virtual mixer software (such as Voicemeeter) that will combine what comes out of Zoom with what comes out of your microphone.

[@YoramSolomon]

NDI would synchronize video and audio if you get both through the same channel, but that doesn't happen... Plus, OBS buffers audio, and at some point creates delay.

[@chrisc958]

Yoram, I am enjoying your video and its step by step instructions. Question. You mentioned during the NDI 4 Tools installation that you don't run any software or apps that you are not going to need to be using so it does not use your RAM resources. The desktop I am using will be dedicated to streaming, but I want to make sure that I am being efficient with the RAM resources. How do I manage the opened items especially in Start Up? Thank you.

[@YoramSolomon]

Chris, thank you for your kind note. Two answers: first, you just shut down any application you don't need. For me, the Chrome browser almost always is the biggest RAM hog... I just looked, and I think that 60% of the RAM is used by Chrome... To the second answer: If you write "Startup Apps" (probably writing "Startup" will be enough) in the bottom window, near the Windows logo, the "Startup" settings window will open. Another way to get there is through entering Windows Settings, then Apps, then Startup. You will see all the apps that will open automatically at startup. On the right side of each one is an on/off slider, which you can switch to off. Below that slider, it also tells you how much of an impact that this app have on your computer's performance. I hope this helps!

[@MrBrettStar]

Nice video but was wondering how does the NDI method compare to using Audio Monitor plugin?

[@JoshKaufmanstuff]

@3:10 is it possible to use auxiliary effects routing in Voicemeeter to go to an app that can delay audio? 🤔

[@keywestconcheyes6262]

Just found your awesome channel, Yoram, and immediately subscribed! This was just the info I have been looking for and I absolutely LOVE your fun and easy-to-understand delivery. :) One question, since it's clearly been awhile since you released this video, have you discovered that you no longer have to start the virtual camera in OBS for the video to show up in Zoom? I still have to do that for Teams, but not Zoom.

[@nicki9905]

Thank you for video. I want to bring audio from zoom to OBS and live stream in youtube. Does NDI work for that as well?

[@eriktaasti]

Many thanks, however, when using the methods in your previous video on this: 1) Install Virtual Audio Cable 2) Go to Settings and set OBS to monitor audio using Virtual Audio Cable 3) In the mixer's advanced properties, set audio sources that you want audible to Monitor and Output 4) Set the audio input in Zoom to Virtual Audio Cable The filters( Noice Suppression, Noice Gate etc.) I add in OBS is working in Zoom, Skype etc.?

[@bruxy70]

When you describe using the Monitor at 2:43, did you mean configuring Virtual Cable as the monitoring device and turning on monitoring for the microphone, or do you refer to the Audio Monitor filter? I was using the first - did not work well. But since I started using the new audio monitor filter, it seems to work fine ( obsproject.com/forum/resources/audio-monitor.1186/ ). Would the NDI output be even better? Thanks!

[@YoramSolomon]

Yes, the first one... Using VC as the monitoring device and turning monitoring for the microphone. I ended up liking NDI more...

[@gpeterson5310]

Yoram, nicely done! I am encountering a blurred degraded video signal from the NDI into Zoom. A quick search on the topic shows many others with a similar experience. Is there a processing speed requirement?

[@gpeterson5310]

I discovered a fix by going into the Video advanced setting in Zoom and changing the Video Rendering Method from Auto to GDI. Problem solved! Best wishes.

[@timpolster]

Thanks for your great video. Do you know if there is any compression added to the OBS virtual output? I want to make sure the quality level is high when the signal arrives at the Zoom program which will compress it further. Thanks!

[@YoramSolomon]

Ah, Tim, I'm glad you asked. There is, but you can control it. If you go to Settings > Output, you will see the video bitrate element. The LOWER this number is, the HIGHER the compression rate it. I played with numbers from 2500 Kbps (2.5 Mbps) up to 50000 Kbps (50 Mbps). I could notice the difference in performance but, more than all, the performance in file size (note that while the Video Bitrate is in the "Streaming" section, the Recording section has "Recording Quality" which I have set (also the default) to "Same as stream."

[@tonimuller7602]

Thanks a lot. I made it and it works great beside one thing: Although usb-mic setting within OSB is set to 0db the sound via NDI within Zoom is much more silent than usb-mic direct if this was chosen within Zoom. Why? Difference might be at least 30%... Otherwise thx again for this wonderful tutorial!

[@YoramSolomon]

Thank you for your kind comment, Andreas. I actually think that the difference is much more than 30%. Note my comment at 14:44 of that video, and where you can change the volume setting. I no longer go with +6db, I go with +20db to get the same sound level (!). I'm guessing it's just a matter of definition of what NDI believes the sound level should be, versus what microphones put out. My guess is also that it is driven by other systems than OBS/Zoom... So, just take it up to +20db. I hope this helps.

[@tonimuller7602]

Hi Yoram! Me again. One more question/remark... well it works, but sync delay is still quite obvious within live Zoom-session. Even if the mic delay is set to (maximum of) -950ms; sometimes that fits... but than again seconds later it does not... I guess it‘s still a question of other processes on the PC (which I tried to close of course). Any other idea? Iliked the idea of NDI in order to use OBS on a PC and than using NDI just send it to another PC which just runs the Zoom session... but as mentioned... just still too much delay (by the way: no delay if I stay just to one PC and use regular audio/mic source on (same PC) within Zoom.... Hopefully you understand what I mean... anyway thx again for your work!

Andreas, it honestly sounds like you might running into the issue I'm running into: my audio and video desync for different amounts, and very inconsistently. Turns out my processor is maxing out when trying to record and do zoom/discord (video chat) at the same time. What's your task manager say for your processor when you have all this going?

Thanks for the Video. Do you know if this helps with playing your media source audio into Zoom? I’ve been having trouble on Teams getting my media source or desktop sounds to show up on the plate form even though my microphone and video are working just fine.

[@YoramSolomon]

That's a great question, Juan, and I'm planning another video on that at some point. But for now, when your OBS scene includes another source of content with audio, that source will show up in the "advanced audio properties" window. Just make sure that you do "audio monitoring" and select "Monitor and Output" for that source, and you'll be fine. This allows you to choose what sources will go out through NDI. I hope this helps!

However, I selected the NDI Output Settings to OBS, the system tray for OBS virtual camera was not able to show OBS output, it showed remote computer only. Therefore, there was no audio input (i.e. Microphone) sound output from OBS to Zoom meeting. Many thanks.

Is the plugin streaming in 4K or it is only in 1080?

I'm not 100% sure, but two things to consider: (1) NDI 5 is out (which I believe supports 4K or even more), and (2) I'm not sure what is the max res coming out of OBS. It might be that OBS is limiting to 1080p.

[@rastoges]

Yoram, thanks for very clear instructions. This solution works great for me as long as I use only my microphone as a sound source. As soon as I want to use audio from my desktop (i.e. when I have a video in my powerpoint slides), both Zoom and MS Teams are trying to cancel out the sound and the virtual meeting participants can hear the sound from the video distorted or not at all. Even when I reduce the noice suppression to minimum, the sound is still distorted. I suspect it has something to do with the fact that both Zoom and PowerPoint output the sound to same audio output device/spekeares. Any idea how to get videos and other sounds play through zoom properly?

[@YoramSolomon]

Check out the audio mixer in the middle of the bottom part of OBS. Make sure only what you want is unmuted, and everything else is muted. Also, in NDI, make sure you are setting audio volume up (I use +20dB).

Hi Yoram, hope you're keeping safe always. I am contacting you from Sri Lanka. Your video has been very informative and I have successfully done and followed instructions accordingly. I must say you are very thorough and clear in everything. Kudos to you. My question is the sync offset as due to low internet in our country we use ZOOM as the livestream platform. Long story short how do I ensure the audio and video is synced right from the beginning. I have noticed that NDI has better AV than tradionaly using the OBS virtual cam and audio cable. My main concern is using NDI regarding the AV SYNC. Hope I am clear.

I use this configuration and had Audio set at 0db and I had complaints about being being slightly too low, I will try moving tp +6db, hopefully it wont overdrive the audio. I am also running compression & a filter in OBS so maybe I am doing too many things, I had the Compression Gain set at +2db and moved it to +4db and that helped with raising the audio level. I will play around with it, moving the compression back to +2db and raising it to +6db in NDI.

[@YoramSolomon]

I ended up using +20db on NDI. No distortion.

Alexander, how do you know that the zoom reception of your images and video is blurred? Here are a few things I would do. (1) start your own zoom call and record locally. Is the recording blurred when you record locally? (2) If they are blurred even when recorded locally, I would record a video from OBS (there is a "Start recording" button in OBS). Is it blurred even when recorded by OBS? Once you tell me what you found it--it will be easier to continue to diagnose it. I hope this helps.

Check the OBS mixer settings. I think that you have BOTH the PC output AND the microphone coming out at the same time. One of them probably has a delay, and that's why you hear an echo. If not there, it could be in the Windows Audio Mixer settings (right click on the speaker icon in the system tray and then select "Open Volume Mixer").

Hi Matt, the delay in the recording is different than the delay in streaming. I experienced the same thing. Also, I found that, depending on my computer loading (and I'm sure other factors, as well) the delay will change over time. I found the BEST method is to have a second computer (or even a mobile phone or a tablet), connect to the same call as another participant, put a headset on that device, and just adjust until sync is perfect.

If i Am not actually in person at the live event to hear how far away the delay speaches actually is. My issues is.. that when i am at the live event space.. the listen back on OBS and the listen back widdin the event space is not on the same timing. IF.. i say IF.. i click around in OBS. Now if i just open OBS with everything going on .. without touching anything around in the canva .. then all is perfect in every way. But as soon as I click around in OBS canvas then the listen back audio in OBS is not on same tempo as the real and natural output sound in the event space How do I get the OBS monitor output in the advance audio property to match up with the event space output sound as i am there in person.

hi brother... its a nice video.. but i am stuck on step no 1. i installed NDI OBS plugin. as soon as I installed it, and run OBS , it says NDI runtime not Found. I am using OBS 29.0.2 and NDI plugin as 4.11.0. can you please help to resolve the issue. tried to google , but could not find the solution. please help

[@YoramSolomon]

Sorry, I switched to a new computer, and haven't installed NDI. I needed NDI when my previous computer was showing an audio sync issue, but the new computer is a gaming computer, and doesn't have that problem, so I didn't install NDI.

how to set up zoom breakout rooms to zoom then go back to zoom breakout rooms? Thank you for your response.

[@YoramSolomon]

I am not sure what you are asking... can you describe the scenario in more detail?

[@benjiemaynopasofficial]

@@YoramSolomon I made a zoom meeting and then put the participants in the zoom breakout rooms. I want the happenings in each room shall be sync in the OBS. Then I will let this shown in each breakout rooms. in short ZOOM BEAKOUT ROOMS to OBS to ZOOM BREAKOUT ROOMS. I hope this more clear. hehehe

[@benjiemaynopasofficial]

@@YoramSolomon i hope you can help me. Thanks.

[@YoramSolomon]

@@benjiemaynopasofficial , if I understood correctly, you want what happens in every breakout room to be transmitted, aggregated, and then sent back to each of the breakout rooms. So, in every breakout room, you will be able to see what's happening in the OTHER breakout rooms, as well. Did I understand correctly? I thought about it. It's possible, but might take a bit more resources that you thought... The way I can think of it right now is to have TWO zoom calls taking place at the same time. One of the computers in EACH breakout rooms will be connected through HDMI to an HDMI-to-USB connector to a second computer in the same location, which will be connected through a SECOND Zoom call to the other "secondary" computers in every breakout room. The HDMI OUTPUT from this extra computer will be connected through a SECOND HDMI-to-USB adapter to the same computer that shared the HDMI output with that extra computer, and will be handled as a second camera. If you are serious about doing this, and willing to have an extra computer in EVERY breakout room, with a SECOND Zoom call, let me know, and I will draw a picture for you.

[@benjiemaynopasofficial]

@@YoramSolomon Yes this is correct. Hopefully you can draw me a picture of the process. It will be a great help for what I want to present in our church. Thanks.

[@kukuhbasuki2099]

which one do you prefer? using NDI or VIRTUAL CABLE?

[@YoramSolomon]

I prefer NDI. It feel "cleaner," although CABLE is a little simpler. I am planning on downloading an NDI-compatible iPhone webcam app. NDI allows more paths whereas CABLE only allows one. I hope this helps.

I’ve been experimenting with the NDI workflow. I’ve not had time to properly trouble shoot it, but I’ve noticed the NDI audio is full of crackles and clipping noises. When you record the Zoom call and playback the audio, it’s full of terrible audio artifacts. It’s too bad. I really want this workflow to be stable. I’d love to get the clean processed audio out of OBS but over the NDI connection, it’s so degraded that is not worth it at the moment. I’m sure I’ll find a solution soon.

[@YoramSolomon]

I don't have this issue with it. I wonder what is your computer loading and if that could be the reason. My computer is a gaming laptop that I use for video editing, so it is pretty powerful.

[@TangleWireTube]

@@YoramSolomon I’m on a solid home build PC machine. It’s not likely a processing bottle neck. I’ve somewhat fixed it in my Zoom recordings. In Zoom’s advanced audio settings there’s an optimize for music option. It makes for a heavier stream, but the audio quality issues are resolved. I’ve tried using the NDI audio outputs to record elsewhere and found poor audio quality there as well. Unpredictable quality issues. Sounds a lot like a buffer issue. Admittedly, I’m dong a more complicated set up than most would require. So I’m bound to face more trouble shooting issues. I’ll have it solved shortly. Just haven’t had the time to do a deep dive on the issue yet.

[@YoramSolomon]

Interesting. I look forward to hear what you found. Thanks for letting me know!

[@jotaroandres]

@@TangleWireTube Ryan, If you find a solution to this, I would love to know. I'm getting a bit of crackle in the Zoom audio as well. I'll try the advanced audio settings for now and see how it goes

[@linepoto]

after it work when i install it, then went to sleep. next day it is saying obs is not operational. what happened.

Check out this video. I'm not sure if this is what happened to you, but if it is, this is the solution: kzbin.info/www/bejne/j3mcnYd9eciArc0
