Building Your First Scene

Scenes are the building blocks of OBS broadcasts. Each scene contains sources—video captures, images, text, and browser elements that compose your stream layout.

Essential Sources for Streaming

1. Video Capture Device — Your webcam or capture card

2. Display Capture — Full screen recording

3. Window Capture — Specific application capture

4. Audio Input Capture — Microphone

5. Audio Output Capture — Desktop audio

6. Image — Logos, overlays, backgrounds

7. Browser Source — Alerts, chat widgets, custom HTML

Creating a Professional Layout

A typical streamer setup includes multiple scenes:

Scene 1: Starting Soon - Background image, text overlay, background music

Scene 2: Main Content - Game/Screen capture, webcam (corner), alert browser source

Scene 3: Be Right Back - BRB image, looping music

Scene 4: Ending - Thank you message, social media handles

Audio Configuration Best Practices

Poor audio ruins streams faster than video issues. OBS provides professional-grade audio mixing.

Audio Mixer Setup

The Audio Mixer dock shows all audio sources with real-time levels:

Green zone (-60 to -20 dB): Too quiet
Yellow zone (-20 to -9 dB): Optimal range
Red zone (-9 to 0 dB): Risk of clipping

Target levels:

Voice: Peak at -12 dB, average -18 dB
Game/Music: 6-10 dB below voice

Essential Audio Filters

1. Noise Suppression — Remove background noise (RNNoise recommended)

2. Noise Gate — Silence audio below threshold

3. Compressor — Even out volume spikes

4. Limiter — Prevent clipping (set to -1 dB)

When OBS Meets Its Limits

OBS excels at local broadcasting, but creators scaling their business often need:

Monetization tools — Subscriptions, pay-per-view, donations
Multi-platform simulcasting — Stream to multiple destinations
Video-on-demand — Automatic recording and hosting
Branded player — White-label viewing experience
Analytics — Viewer metrics and engagement data

For creators outgrowing OBS scope, platforms like dcast.tv complement OBS by handling distribution and monetization. You continue using OBS for production while dcast manages the business side—subscriptions, payments, and audience analytics.

Start with the Auto-Configuration Wizard, build simple scenes, and gradually explore advanced features like scripting and plugins. The learning curve pays dividends in broadcast quality and production efficiency.

For creators ready to monetize their streams, combining OBS with dedicated platforms handles the business complexity while keeping your production workflow intact.
