BitFocus Companion 4.0 is here, and it keeps changing how we do live production—especially in the church tech world—because it gives you simple, reliable “buttons” to control almost anything from a Stream Deck. In this video I walk you through a true beginner start in 2025: what Companion is, why it’s so popular (free + open source), how it integrates with Stream Deck hardware, and how I use it in real ministry production. At my church we use Companion to do things like turn the projector on/off, recall PTZ camera presets, and even control our ATEM from front of house. I start from a fresh install (Companion 4.0.2 in my case), show you the launcher settings, and then jump into the browser-based GUI where connections and modules live. From there, I connect to ProPresenter by enabling Network + Remote inside ProPresenter, setting a password, and entering the IP/port in Companion. Then I build my first buttons—using press actions to switch ProPresenter Looks (default, worship, sermon)—and I show why feedbacks are such a big deal: the button color can change automatically based on which Look is active. Finally, I plug in a Stream Deck XL over USB, confirm it shows up under Surfaces, and demonstrate how everything stays synced between the on-screen grid and the physical controller. Companion is just way more powerful than the native Stream Deck software right now, and this is a great foundation to start building your own church production control system.
