Display & Output

RheoCast separates the operator view (what your media team sees) from the display output (what your congregation sees on screen). This guide covers every output option.

This page is about the screen in the room. For streaming to Facebook or YouTube, see Streaming & Recording — RheoCast does that itself in the Broadcast tab. The outputs below are for your projector, and for feeding scripture into an external switcher if you already use one.

Display Output Modes

Configure the primary output under Settings → Output → Display Output Mode.

Windowed

A separate draggable window showing the current verse. Available on all plans.

Best for: Testing, preview monitors, picture-in-picture setups, or running RheoCast alongside other presentation software.

Fullscreen (Second Display)

Automatically fills an external monitor or projector. Available on Pro and Ministry plans.

Best for: Dedicated projector output in a sanctuary. Connect your second display before launching RheoCast.

Save settings after changing output mode. The display window reconfigures when you switch modes.

NDI Output

Available on Pro and Ministry plans.

NDI sends RheoCast's verse output as a network video source that production software can receive directly — no HDMI capture card required.

Setup

1. Open Settings → Output.
2. Enable NDI Source.
3. Set your Source Name (visible on your network, e.g. RheoCast-Main).
4. Choose Resolution (1080p recommended) and Frame Rate (30 fps is standard).
5. Save settings.

Lower Third Mode (NDI)

Enable Lower Third Mode inside the NDI settings to output a transparent lower-third overlay instead of a full-frame display. The scripture text appears at the bottom of the frame with a subtle gradient, while the rest of the frame is fully transparent (alpha channel).

This works independently of your display output mode — you can show Fullscreen on the church projector while simultaneously sending a Lower Third overlay via NDI to your livestream software.

No extra window appears on your screen. The lower-third rendering happens entirely inside the NDI pipeline.

Adding to production software

Ensure all devices are on the same local network. NDI performs best over wired Ethernet.

Browser Source (Web Overlay)

Available on Pro and Ministry plans.

The Web Overlay serves a local web page that OBS, vMix, or other software can load as a Browser Source — ideal for transparent scripture overlays on streams.

Setup

1. Open Settings → Output.
2. Enable Web Overlay.
3. Copy the generated URL shown in settings (click Copy).
4. In OBS (or your streaming software):
   • Add Browser Source
   • Paste the URL
   • Set width/height to match your stream resolution (e.g. 1920×1080)
   • Enable Shutdown source when not visible if desired

Lower Third Mode (Browser Source)

Enable Lower Third Mode inside the Browser Source settings to switch the overlay to a transparent lower-third layout. Scripture text appears at the bottom of the frame over a gradient backdrop — the rest is fully transparent.

Like NDI Lower Third, this works independently of your display output. You can run Windowed or Fullscreen for your in-venue projection while the browser overlay renders a separate lower-third for your livestream.

The overlay is transparent until a verse is displayed, then shows the scripture with your configured appearance settings.

Appearance Customization

Open Settings → Appearance to customize how verses look on screen.

Background

• Solid color — Simple black or brand color
• Gradient — Two-color gradient with adjustable angle
• Image — Upload a custom background image
• Transparent — For NDI and browser overlay compositing

Typography

• Verse font — Choose from built-in and Google Font options (Georgia is the default)
• Font size — Default is 48px; adjust for your venue's screen size and viewing distance
• Bold, uppercase, alignment — Fine-tune readability
• Text outline & shadow — Improve legibility over busy backgrounds

Reference line

Customize the book/chapter/verse label separately:

• Reference color and font
• Reference size and alignment

Changes preview in real time. Click Save Settings to apply.

Clearing the Display

Press Escape at any time to clear the current verse from the output (closes Settings first if open). The overlay returns to its empty/transparent state.

Verses update the Display Preview in the main window even when Go Live is off. Go Live must be ON for verses to reach the external output.

Output Comparison

Using RheoCast with an external switcher

Most churches use the Broadcast tab and retire their old switcher — it covers cameras, scenes, recording and streaming without a second application.

If you are migrating from OBS, vMix, Wirecast or ProPresenter, this page is your bridge. RheoCast can act as a scripture layer inside the stack you already have, so you can move across over several weeks rather than in one Sunday.

Feeding scripture into your switcher

Pick one of these:

• Browser Source — Enable the web overlay in RheoCast and paste the URL into OBS as a Browser Source. Turn on Lower Third Mode for a transparent band at the bottom of frame.
• NDI — Enable NDI in RheoCast and add an NDI Source in OBS or vMix on the same network. Lower Third Mode works here too.
• Projector + capture — Fullscreen RheoCast on a second display and capture it over HDMI or with a window capture. Simplest, least flexible.

Then start transcription in Present › Live and turn Go Live ON so detected verses reach the output your switcher is reading.

Who does what

NDI is worth choosing when RheoCast and your switcher run on different computers — it crosses the network, so the presentation machine and the production machine do not have to be the same one.

Tips for Production Teams

1. Test before service — Verify your NDI or browser source appears in OBS/vMix with correct transparency.
2. Match resolutions — Set NDI and browser source dimensions to your stream output (usually 1080p).
3. Separate machines — NDI allows RheoCast to run on one computer while OBS runs on another.
4. Save appearance presets — Configure once, then reuse across services.
