Creating and Managing Scenes

Scenes are the foundation of your OBS setup. They allow you to organize different layouts and switch between them seamlessly during your stream or recording.

Scene Basics

Think of scenes as different "layouts" for your stream. For example, you might have:

• A "Starting Soon" scene that displays while viewers are joining
• A "Gameplay" scene showing your game with webcam overlay
• A "Just Chatting" scene with a larger webcam view
• A "Be Right Back" scene for short breaks
• An "Ending" scene to thank viewers and display social media

Creating a New Scene

1. In the Scenes panel, click the "+" button
2. Enter a descriptive name for your scene (e.g., "Gameplay")
3. Click "OK" to create the scene

Organizing Scenes

You can rearrange scenes by dragging and dropping them in the Scenes panel. Consider organizing them in the order you'll use them during your stream.

Scene Collections

Scene Collections allow you to create and save multiple complete setups. This is useful if you stream different types of content or games that require different layouts.

Creating a New Scene Collection

1. Click on "Scene Collection" in the top menu
2. Select "New"
3. Enter a name for your collection (e.g., "SCUM Stream" or "Just Chatting")
4. Click "OK" to create the new collection

Each Scene Collection maintains its own set of scenes, sources, and settings, allowing you to quickly switch between completely different setups.

Scene Transitions

Transitions determine how OBS switches from one scene to another. Professional-looking transitions can significantly enhance the quality of your stream.

Default Transition Types

• Cut: Instantly switches between scenes with no animation
• Fade: Gradually fades out the current scene while fading in the new one
• Swipe: Slides the new scene in from a specified direction
• Slide: Similar to swipe but with different animation properties
• Stinger: Uses a video file to create a custom animated transition

Setting Up Transitions

1. In the "Scene Transitions" dock (usually at the top of the interface), click the "+" button
2. Select your desired transition type
3. Configure the transition settings (duration, direction, etc.)
4. Click "OK" to add the transition

Setting Transition Duration

For smooth transitions like Fade or Swipe, you can adjust the duration:

1. Select the transition in the Scene Transitions dock
2. Change the "Duration" value (in milliseconds)
3. 300-500ms is typically a good range for most transitions

Scene-Specific Transitions

You can set different transitions for specific scenes:

1. Right-click on a scene in the Scenes panel
2. Select "Transition Override"
3. Choose the transition type and duration for that specific scene

  • Software (x264): Uses your CPU for encoding. Can provide better quality at lower bitrates but uses more CPU resources.
• Rate Control: CBR (Constant Bitrate) is recommended for streaming
• Bitrate: Depends on your internet upload speed and streaming platform
  • 720p30: 3,000-4,500 Kbps
  • 720p60: 4,500-6,000 Kbps
  • 1080p30: 4,500-6,000 Kbps
  • 1080p60: 6,000-8,000 Kbps
• Keyframe Interval: 2 seconds (required by most streaming platforms)
• Preset: "Quality" or "Max Quality" for NVENC; "Medium" or "Fast" for x264
• Profile: High
• Look-ahead and Psycho Visual Tuning: Enable if available

Recording Settings (Advanced Mode)

• Recording Format: MKV (safest option as it can recover from crashes)
• Encoder: Same as streaming or a separate encoder
• Rate Control: CQP (for NVENC) or CRF (for x264) provides the best quality-to-size ratio
• CQP/CRF Value: 15-18 for high quality; 20-23 for balanced quality and file size
• Preset: "Max Quality" for NVENC; "Medium" for x264

Video Settings

Video settings control the resolution and frame rate of your stream or recording. To access these settings, go to Settings → Video.

Key Video Settings

• Base (Canvas) Resolution: Your monitor's native resolution (e.g., 1920x1080)
• Output (Scaled) Resolution: The resolution you're streaming at (e.g., 1280x720 or 1920x1080)
• Downscale Filter: Lanczos for the best quality (or Bicubic if you have performance issues)
• Common FPS Values: 60 for smooth motion or 30 for better quality at lower bitrates

Advanced Settings

Advanced settings control various aspects of OBS behavior. To access these settings, go to Settings → Advanced.

Key Advanced Settings

• Process Priority: Set to "Above Normal" or "High" to give OBS priority over other applications
• Renderer: Direct3D 11 is recommended for most users
