A clear stream without a facecam: layout and audio decisions that do the work.

The short answer

A stream without a facecam is not a stream with something missing; it is a stream where the scene and the audio do the explaining. Decide what shows that someone is there, what tells viewers what is happening, and what they should listen to. The rest of this page is those three decisions, with examples. It makes no claim about whether a facecam changes how many people watch or stay; nobody here has measured that.

The three questions a face used to answer

1. Is anyone there? A face moves; a game capture on its own does not. The alternatives are a visible presence (a cohost’s avatar, a mascot, a panel that says “quiet stream, chat welcome”) or a chat that visibly moves on screen.
2. What is happening? Narration explains intent. Without it: a goal panel (“tonight: first clear”), a now-playing line, or a cohost who reacts to the game.
3. What should I listen to? Game audio, music where the game’s rules allow, a voice. Choose the level of each on purpose, because nothing will be ducked around your speech.

Layout decisions, with examples

Three layouts that work without a face, each built around one OBS Browser source for the Broker (the app asks for Width 800 and Height 600) placed above the game source with its eye icon on.

1. 01Corner companion.

   The game full-frame; the Browser source in a bottom corner with the Bottom left or Bottom right preset, so he sits in that corner with his line opening toward the middle. Keep that corner clear of the game’s own HUD (a minimap, a scoreboard, a health bar) so his captions never cover what the viewer needs. The overlay layout preview gives you the X, Y and size for the Transform dialog.

2. 02Wide lower layer.

   The developer’s own scene runs the source at 1280 × 720, a 16:9 viewport that can sit as a wide layer across the lower part of a 1080p canvas, with a label panel beside him: the goal of the stream, who is talking. The game stays full-frame behind it. How the overlay lays him out inside a viewport other than 800 × 600 is not documented by the app, so check it in a short recording; the source-size article explains the trade-off.

3. 03Centered over open space.

   For games with a lot of empty picture (a card game, strategy at map scale, long menus), the Centered preset puts him in the middle of the source with his line above him. Place the source over the emptiest part of the picture rather than scaling it down hard; scaling a source by more than about half either way costs sharpness.

Whichever you choose: the source must be above the game source, Signal Broker must stay open with the overlay enabled, and the layout is verified by watching a short recording, not by looking at the preview.

Audio decisions

• The game is the baseline. Game audio up; music under it where the game’s rules allow.
• A voice that reacts to the game. The Broker plays through the Windows default output device, so Desktop Audio captures him together with the game. There is no separate audio track yet. Balance him with Broker volume in Settings → Voice & capture and the game in the game; check the Desktop Audio meter and make a short test recording before going live.
• No microphone at all is fine. The app has no microphone input and does not need yours. If you add your own microphone later, it is its own source in OBS, independent of him.
• Headsets. If you switch headsets or speakers mid-session, stop and start the session again.

Captions and text

Without a face, text carries more of the load. The Browser source shows his avatar and spoken captions on a transparent background; Dialogue size sets how large the captions are, and Preview preset shows the result in your browser before you copy the source. If the captions are too small at your output resolution, raise Dialogue size in the app before enlarging the source in OBS.

Add one static line of your own somewhere in the scene: who is talking, and that the cohost is AI. From the setup guide: the commentary is generated by AI; say so on stream or in your description; some platforms and countries require it.

A ten-minute check before going live

1. Start the game first, then the session; bring the game to the front and give him a moment, because he watches before he speaks.
2. Record 30 to 60 seconds with the game and the Browser source in the scene and watch it: is he the size you expected, are the captions readable, is his voice there?
3. Look at where he sits during a busy moment: is any part of the HUD covered?
4. With the game quiet, is his voice at a level that does not jump out of the mix?
5. Does the title or a panel say that the cohost is AI?

Limits

• No claim is made about whether a facecam changes viewership, retention or anything else; no platform statistics are quoted.
• The three layouts are suggestions; how the overlay lays the Broker out inside a viewport other than 800 × 600 is not documented by the app.
• He does not hear you and does not read chat; the app has no microphone input and no chat.
• Founder Alpha is early-access software; the commentary can be wrong, repeated or badly timed, and it is sold to customers in the United States only.
