If you're a streamer you might well use NVIDIA Broadcast inside OBS Studio, but you can also use OBS on its own as a virtual camera with your other video apps. Source: Windows Central (Image credit: Source: Windows Central) It could be something to do with Windows 10 as well, but it's a thing that happens from time to time. And for some reason, this will randomly become the selected camera in Broadcast. Inside my PC I have a PCIe capture card that identifies as a regular, plug-and-play video device, just like a webcam. There's also some quirkiness with which camera it chooses if you have multiple video devices in your system. I'm sure the app could be opened up, but it's designed to use NVIDIA's own hardware and make as little impact on your overall system resources as possible. Broadcast makes use of tech found on NVIDIA's RTX graphics cards, so if you don't have one, you can't use it. Everything it says it will do, it does extremely well, and it runs quietly in the background not requiring much attention. If you can use NVIDIA Broadcast there's nothing you won't like.

The other is video noise removal, which is particularly good for webcams as it makes video look smoother and less grainy. As my colleagues have pointed out, it certainly does what it says.

More recent additions are an auto framing tool that will crop in as a fake zoom but will 'move' as you move to ensure you stay in the center of the frame. If you look closely you will notice around the edges of yourself where things get a bit dicey, but it's perfectly acceptable and you have a choice of quality or performance. It isn't perfect, as none of these software solutions are, but if your webcam is in a small box on a stream it'll be hard to tell you're not using hardware to generate the effect. The main functionality is to blur, remove or replace your background, and in each case, it does a great job. It's particularly useful if you're a streamer, but also if you just want to jazz up your conference calls. But everyone who's ever been talking to me could also be in a really quiet room! Given how good the microphone noise filtering is though there's no reason not to trust it's working as intended. The speaker section again has an area to test out the effect, and it seems to do its thing.

It really does seem to be able to block out anything that isn't your voice, and I've been able to use it consistently on conference calls without turning off my fan or my music without any of my coworkers hearing a thing.
