Multistreaming

What Is Multistreaming?

Multistreaming, also known as simulcasting, is the process of broadcasting live video content to multiple platforms at the same time. Instead of going live on just one platform, you can stream simultaneously to several platforms.

Multistreaming = One stream, Multiple destinations, Maximum reach

How Does it Work?

You can live stream on multiple platforms using:

• Streaming software like OBS Studio with plugins
• Cloud-based streaming platforms
• Hardware encoders that support multiple outputs

These tools take your single video feed and distribute it across multiple destinations in real time.

Technologies that support multistreaming:

1. RTMP serves as the core protocol, ensuring stable connections across platforms.

2. Advanced encoders use multi-threading to output multiple streams from a single encoding instance, reducing CPU usage.

3. Multiplexing reuses the same video and audio data with platform-specific metadata, avoiding redundant streams.

4. Adaptive bitrate streaming adjusts resolution and bitrate to match each platform’s needs for smooth playback.

5. Timestamp coordination keeps all streams in sync, preventing desynchronization over time.

Benefits of Multistreaming

• Maximize reach: Engage audiences on all their favorite platforms at once
• Boost visibility: More exposure = higher chances of discovery
• Save time: No need to repeat the same stream for each platform
• Audience convenience: Viewers can tune in on their preferred app

What to Consider When Multistreaming?

1. Platform Compatibility and Stream Destinations

Ensure the service supports all the platforms you want to stream to (e.g., YouTube, Twitch, Facebook, LinkedIn) and allows for custom RTMP outputs for flexibility.

2. Streaming Quality and Performance

Look for support for high-resolution (1080p/4K) and low-latency streaming. Cloud-based encoding and adaptive bitrate streaming help maintain performance without overloading your device.

3. Ease of Use and Production Features

Choose a user-friendly platform that fits your skill level—browser-based for simplicity or software-based for advanced control. Features like overlays, guest invites, and chat aggregation enhance the broadcast.

4. Analytics and Integration

A good platform offers centralized analytics across all destinations and integrates smoothly with your existing tools (OBS, Streamlabs, Zoom, etc.) for easier workflow management.

5. Pricing, Scalability, and Support

Match the pricing to your budget and streaming needs. Ensure the platform scales with your growth and offers responsive support and regular updates.
