This is a clean way to show a single application's interface live — your editor (Premiere, Resolve, Flame), a presentation (Keynote) or any other tool. The trick over plain screen sharing: you build a **screen-sharing scene in OBS that focuses on one application's window**, so everything else on your desktop stays hidden and your client sees only what you want them to — clearly framed, with the audio included. These steps apply to **both** dfine.io products that livestream — Streaming Classic and Review. The encoder setup is the same; only where you copy your ingest URL and stream key differs by product. See [Where do I find the ingest server URL?](/en/where-do-i-find-the-ingest-server-url). Get OBS ready before you build the scene. Create a new scene called **GUI Screensharing**. Creating the GUI Screensharing scene in OBS Add a **macOS Screen Capture** source and give it a name. Adding the macOS Screen Capture source In the window that opens, select the settings as shown. Screen capture settings in OBS Right click the preview, then choose **Transform**, then **Fit to Screen**. Fitting the source to the screen in OBS Turn off the default desktop audio, because no audio comes in on that channel. The audio is delivered through the **macOS Screen Capture** source instead. Audio settings for the screen capture in OBS With the latest OBS version you no longer need the BlackHole audio drivers, which makes the setup much simpler. Add your connection details in OBS and go live.
