Short answer: you can create a starting soon screen for Twitch using a simple setup in OBS or Streamlabs, either by using templates or building your own design with text, countdowns, and branding, then adding it as a dedicated scene that you switch to before going live. What a starting soon screen does

• It fills the screen while you prepare your stream, displaying branding, social handles, a schedule, a countdown, and chat prompts to engage viewers.
• It loops or remains static until you switch to your main streaming scene.

Popular approaches

• Use ready-made templates: Many editors and template libraries (Canva, FlexClip, or OBS community templates) offer starting soon screens you can customize with your own logo, colors, and text. Then export as an image or video and import into OBS as a media source. Templates save time and ensure a polished look.
• Build from scratch in your broadcaster software: Create a dedicated scene named “Starting Soon” and populate it with:
  • Background image or video
  • Your channel name/logo
  • A countdown timer (optional)
  • Social handles or schedule
  • Text prompts for chat interaction (e.g., “Let us know what you want to see!”)
• Add a countdown: If you want a countdown, you can either:
  • Use a countdown timer widget/overlay (built into some OBS plugins or browser sources)
  • Create a video loop with embedded countdown (exported as a video file)
  • Use a simple image-based timer with a browser source (countdown script)
• Loop behavior: Ensure the screen loops smoothly if you’re using video, or keep it static if you’re showing it for a fixed duration.

Implementation steps (general)

1. Design or choose a starting soon asset

• Pick a resolution that matches your stream (e.g., 1920x1080 or 1280x720).
• Include your logo, channel name, and any branding elements.
• Decide whether to include a countdown and which information to display.

2. Set up in your streaming software

• Create a new scene named “Starting Soon.”
• Add a media source:
  • If using a static image: add as an Image Source and ensure it fills the screen.
  • If using a video: add as a Media Source and enable “Loop” if needed.
  • If using a live countdown: add a browser source or a plugin-based timer.
• Add text elements:
  • Use a clear, readable font and contrast against the background.
  • Include social handles or a schedule if desired.
• Configure scene transitions:
  • Default to this scene before you go live.
  • Practise a smooth switch from “Starting Soon” to your main scene when ready.

3. Testing and going live

• Do a private test stream or local preview to verify timing, legibility, and transitions.
• Ensure audio levels are appropriate so the screen visuals don’t compete with your microphone.

Tips for a professional look

• Keep it clean: avoid clutter; 1–2 focal elements (logo and countdown) plus essential text.
• Brand consistency: match colors and typography to your channel branding.
• Accessibility: use high-contrast text, large font sizes for readability on mobile devices.

Common pitfalls to avoid

• Overly long countdowns; 60–120 seconds is typical, longer only if you have substantial pre-show content.
• Low-resolution assets; use crisp images or videos to prevent blurriness on large screens.
• Forgetting to switch scenes: ensure you have a reliable habit to switch to the main scene when ready.

If you’d like, describe your branding (colors, logo, any text) and whether you want a countdown, and I can outline a ready-to-implement layout and a step-by- step checklist tailored to OBS or Streamlabs.
