So let’s add our first effect by clicking Add Effect, selecting Background Removal, and then we’ll turn on the toggle button next to it:īoom! That’s it! You can try different effects by switching them in the drop down menu:Īnd like we mentioned you can stack effects. If you’d like to start with a clean slate, or if you want to delete any effects, you can click on the name of the effect and you’ll see x Remove this effect:Ĭlicking on that will remove that effect from the stack and you’ll be starting fresh: You can add multiple effects and put them in any order you like. Under the word effects, you can think of this area like a stack of plugins. Today we’ll focus on the juicy video effects. Once we learn how the effects work on the camera section, you can easily switch over to microphone page and repeat the process with those effects. The nice thing about the Broadcast App is that it uses a pretty uniform interface. Once you’re done that, we’ve got our inputs setup! Adding effects! Once you’ve selected the camera you can set the desired resolution and FPS, and the button circled in red allows you to edit your camera’s settings like focus and brightness, etc. Then let’s switch over to the Camera tab at the top and select our proper source device: The first screen you’re greeted with on launch is the Microphone page:īefore we dive into the actual effects, the first thing you’ll want to do is select your microphone in the top left source area. While we’re mainly interested in the background removal currently, there are some great audio filters in the Broadcast app. You’ll also want to make sure you’re on the latest Nvidia driver which you can get at the link below: The first thing you’ll need to do is install the Broadcast App. Other than that, no requirements, which is great. The RTX 2000 series came out at the beginning 2019, roughly just over 2 years ago, so if you’ve upgraded your system since then or are creating a system for a project, it’s likely you’re going to be using something from the RTX 2000 series or newer. NVIDIA GeForce RTX 2060, Quadro RTX 3000, TITAN RTX or higher This doesn’t mean you need the latest and greatest, thankfully. The only requirement to using these new Nvidia features is to have a relatively recent Nvidia RTX GPU. This means you can access these features quickly and easily in basically any application or environment, whether you’re working in TouchDesigner or just hopping on a Zoom call. Not only did they release the SDK so other applications can add the features natively, they also took the same SDK and wrapped it around a simple app that takes your camera/mic inputs, process them, then creates a virtual webcam with the results. Nvidia did a really smart thing here and looked at how the community uses these tools (something I wish Microsoft would take note of when it comes to Kinect development). In TouchDesigner, we have native access to the Nvidia Background TOP, but sometimes you might want to get access to these features outside of TouchDesigner or do this processing outside of TouchDesigner, and that’s where Nvidia’s Broadcast App comes into play. While not perfect by any stretch, Nvidia’s new machine-learning driven background removal is pretty fantastic. If you told me a few years ago that you could get a real-time background subtraction with no special camera hardware and it can work just about anywhere, I’d be pretty skeptical.
