Oh man that sounds like an awesome rig. I didn’t realize Nvidia Broadcast can reduce background noise like keystrokes until you mentioned it here. Does that really work? If so I now have a reason to buy a new GPU and finally use my cherry mx blues again.

It does work and fairly well at that. However, for the audio processing component of Broadcast, you don't necessarily need an RTX card. There's an official version that does the work in plain old CUDA. Might not be quite as efficient, but also works just fine.

Yep; I used RTX Voice or what it was called on my old 1080TI. With my 3070 I'll use both voice and video, to just slightly blur the background.

We've come an incredibly long way since Genlock on the Commodore Amiga! I use OBS Studio with my Streamdeck, a Logitech Streamcam, NVIDIA Broadcast, a condenser microphone via a Steinberg XLR audio interface along with Elgato Key lights and iHue fill lights for my working from home office Google Meets. Startup and shut downs of the entire stack including launching into Google Meets are automated with the deck (one bu…

How do you find the memory consumption of those apps? I found NVIDIA Broadcast and a few other streaming utils were passively eating like 3GB of RAM. Not typically a concern until you're spinning up VMs and dev environments and suddenly getting paged. I'd love something like Broadcast but much more lightweight, but I haven't found a good alternative yet.

I haven't really paid much attention to the memory usage to be honest; running Windows 11 on a 32GB Ryzen system. It was plenty until some of my Docker requirements started getting greedy (my next system will have 64, but also because I play DCS World now on occasion).

I am however issuing a kill of the NVIDIA Broadcast app with my shut down macro as it will otherwise peg the 3070 usage % at a non idling level, which is somewhat worse for power usage, temperatures and longevity (than not doing it). OBS Studio is also shut down, after stopping the virtual camera with a keyboard shortcut. (It's basically reverse of the start up).

So I'll only have all the software running for the duration of my meeting. I've put the cam on a flexible arm, easy to push out of the way when done and I confirm the light is off.

The shutdown also sets the video lights down to "warm ambient" levels rather than turn them off - especially on dark winter days, they do improve my mood.

And fwiw I had to explain my use of the Streamdeck to my tax accountant; they were cool after hearing a version of the above. :) The macro features are such a stress reducer, really.

(And no, I never stream anything. Would rather not broadcast my ugly mug in public, but at least with this I can cast myself in the best possible light - pun intended - to my colleagues).

I recently started a company focused on providing a cloud backend for OBS - all the collaboration bits (script writing, storyboarding), reviews, and publishing/distribution. All the workflows you do outside of OBS itself, basically, and integrated with OBS through a plugin. We also sponsor OBS with a $10k/mo donation.

If this is a problem you’re having I’d love to talk about it, or even if you just want to share your experience of what works well for you. My email is in my profile.

Unless OBS (or FFMpeg or GStreamer) is giving you something you need (maybe correction on your camera or some touch up filters or whatever), I'm not sure if you (the royal "you") really need OBS for this setup. I also have a very similar setup. High quality webcam, high quality headset, and a few lights pointing into my face to offset the lighting in the room. I have Zoom configured to use original audio and turn off…

Nice setup!

OBS scenes is the killer feature for me, so it just works well. In addition the AFK one I've also set a couple of zoom levels that frame me better if I decide to slide my seat back a bit.

I even have scenes for sprint planning estimation sessions. 1-3-5-8 etc superimposed over my picture. :D (they are numbered buttons on the Streamdeck).

Nothing else at the moment, even as opt-in. We're considering this in the future, but want to make sure we do it right.

Make sure you do it differently than how Muse Group did it with Audacity (specifically the announcement and explanation of why and what parts) [0]. Which I'd argue is not particularly difficult to do.

That's a configuration problem, and not hard to correct. Tell him to go into the audio settings, then "advanced audio settings", and add the "sync offset" in milliseconds required to bring the audio and video into sync. Also, it's likely that his camera is mostly at fault; OBS with my Logitech camera doesn't have any significant lag. OBS itself has very little lag.

That’s desync, not latency/lag. They’re different things, and this solution will actually make the lag worse as it deepens the buffer. OBS virtual cameras definitely have noticeable lag with most people I have seen using them on Teams/Zoom.

The meaning of lag is notoriously varied--I think GP understood it as a consistent delay, and you and GGP are saying that OBS introduces an inconsistent delay, i.e., dropped frames or stuttering. The one using the virtual camera should be able to diagnose through the stats 'Frames missed due to rendering lag', 'Skipped frames due to encoding lag', and 'Dropped Frames (Network)', unless the virtual camera driver is somehow the culprit.

Or does one of you mean that even the constant delay is significant enough to be noticed on top of the video call latency?

I just realized that I don't know how the missed/skipped counters are actually defined--presumably frames are skipped for encoding if the encoder can't keep up with the framerate and missed for encoding if if any other part of the pipeline preceding it cannot.

I'd say that it works very well. So well in fact that as I reinstalled windows and watched F1 on Sunday I was surprised to see that Ferrari had managed to remove the engine sound from the drivers microphone, but at some cost to the clarity. Turns out the background noise removal was turned on for my output too.

Wow, that’s… kind of insane. Cool. I’m gonna have to check it out.

It also completely eliminates screaming cats and babies. It's worth the price of the GPU upgrade alone.

I know that Slack and Google are slowly baking these features in, but NVIDIA are in a league of their own. AMD not having them made my GPU brand choice easy last time I upgraded.

Please write a blog post detailing your setup. I’d love to do something like this but could really use some hand holding for the setup part.

Haven't done any blog posts in decades, but if I was to start again it would be a good topic to cover.

It can be a bit costly, but found it well worth it now that it's done. I'll send you an email in case you have any specific questions.

Have been using OBS for over a year coz Grabilla is not supported on my new company laptop. A huge learning curve is needed to understand OBS. For ex - I have still not been able to figure out how to record audio using AirPods Pro Secondly, whenever I connect an external monitor to my primary laptop, the audio is not recorded. Some challenges I face while using OBS. Many a times it's really frustrating

> A huge learning curve is needed to understand OBS.

A big no. You can start streaming or recording with OBS within twenty minutes of installing it.

I did. Never used it before. I wanted a simple coding set-up where the whole screen is the main source and my webcam feed is in the corner as a box.

> Secondly, whenever I connect an external monitor to my primary laptop, the audio is not recorded.

Doesn't happen with me. Try restarting with the monitor added.

I use a condenser microphone, a Wacom graphics tablet (kudos to them for first class Linuc support), a webcam, an external monitor, and so on.

If you want to start streaming or recording within thirty mimutes of installing a SW, use OBS.
