Streamlabs Replay Buffer helps streamers capture key moments without keeping every minute of a broadcast. This tool records short clips automatically or on demand, making it easier to preserve highlights for later use on Twitch, YouTube, and other platforms.
Streamlabs integrates directly with OBS Studio, so you can trigger instant saves, set storage limits, and manage clip organization from within your streaming workflow. Below is a quick overview of how the feature compares across common setups.
| Feature | Replay Buffer Type | Max Clip Length | Instant Save Shortcut |
|---|---|---|---|
| On-Demand Recording | Manual clip capture | Unlimited (configurable) | Custom hotkey |
| Pre-Roll Buffer | Seconds before trigger | Up to 60 seconds | Auto-saves on event |
| Storage Management | Local folder control | Custom file limit | Auto-delete oldest clips |
| Platform Integration | Twitch, YouTube, Facebook | Customizable metadata | Direct publish option |
Pre-Roll Buffer Configuration
Understanding how the pre-roll buffer works is essential for capturing the perfect moment. The buffer stores a short segment of video before you press save, so you do not lose the action that leads up to a clutch play.
Key Settings
- Buffer duration in seconds
- Automatic overwrite of old segments
- Low disk warnings
- Custom hotkeys for manual save
Clip Organization and Workflow
Efficient clip organization reduces time spent searching for highlights and keeps your library easy to navigate. You can name clips with relevant tags, sort by game, and flag viral moments for quick access.
Suggested Workflow
- Set a consistent naming template
- Use hotkeys to save at the exact moment
- Review clips immediately after stream
- Archive older content to free up space
Performance and Resource Management
Replay Buffer performance depends on system resources and settings. Balancing quality, resolution, and storage ensures smooth recording without affecting gameplay or encode performance.
| Setting | Recommended Value | Impact on CPU | Impact on Disk |
|---|---|---|---|
| Resolution 1080p | 1920x1080 | Moderate | Medium |
| Frame Rate 60fps | 60 fps | Higher | Higher |
| Bitrate 15 Mbps | 15000 kbps | Moderate to High | Higher |
| Buffer Pre-Roll 5 sec | 5 seconds | Minimal | Low |
Storage, Limits, and File Management
Configuring storage settings helps prevent lost clips and keeps your drive from filling up unexpectedly. You can set maximum file size, choose save location, and enable automatic cleanup to retain only the most valuable moments.
Management Tips
- Define a maximum clip age in days
- Monitor free space with alerts
- Separate clips by stream category
- Backup high-performing clips to cloud
Optimizing Replay Buffer for Regular Streaming
Adjusting settings to match your hardware and content style makes the feature more reliable and easier to use during every broadcast.
- Match buffer length to game pacing
- Test hotkeys in offline mode
- Schedule periodic storage reviews

FAQ
Reader questions
How long is video stored in the pre-roll buffer before it is overwritten?
The buffer retains footage for the set duration only, such as 5 or 10 seconds, and continuously overwrites old segments unless you save a clip manually.
Can I change the hotkey for saving a clip during a live stream?
Yes, you can assign any available key combination in the Streamlabs settings to avoid conflicts with other software shortcuts.
Will enabling the replay buffer reduce my stream frames per second?
Minimal impact occurs when settings are balanced, though higher resolution and frame rate increase encoding demand and storage use.
Where are saved clips located on my computer by default?
By default, clips are stored in the Streamlabs folder inside your Videos directory, but you can redirect this path to any drive or cloud-synced folder.
