Boost Your Production: NDI-CONTORLLER Best Practices and Tips

Overview

NDI-CONTORLLER is a tool for managing NDI sources and routing video/audio across a production network. Use these best practices to improve reliability, performance, and workflow efficiency.

1. Network setup and optimization

• Use a dedicated VLAN: Isolate NDI traffic from general network to reduce congestion.
• Prefer wired Gigabit Ethernet: Use at least 1 Gbps; 10 Gbps for high channel counts or 4K.
• Enable IGMP snooping: Reduces multicast flooding on managed switches.
• Avoid Wi‑Fi for primary NDI streams: Use only for monitoring or low‑bandwidth tasks.
• Monitor bandwidth: Calculate per‑stream bitrate and ensure aggregate fits available capacity.

2. IP addressing and discovery

• Static or DHCP reservations: Assign fixed IPs or DHCP reservations for core devices to simplify routing and troubleshooting.
• Use consistent subnets: Keep NDI devices on the same subnet where possible to simplify discovery.
• Name devices clearly: Human‑readable device names speed up source selection and reduce mistakes.

3. Source management and routing

• Group sources logically: Create scenes or groups (camera, graphics, playback) for quick access.
• Limit visible sources: Hide unused or noisy sources to reduce clutter and discovery traffic.
• Preconfigure routing presets: Save layouts and routes for common show configurations to reduce live errors.

4. Performance tuning

• Adjust codec/quality per source: Use lower quality for monitoring or multiview, higher for program outputs.
• Use hardware encoding where possible: Offload CPU with GPUs or dedicated encoders to keep system responsive.
• Keep frame rates consistent: Match frame rates across devices to prevent dropped frames or stuttering.

5. Redundancy and reliability

• Implement failover paths: Use secondary links or routers for critical paths.
• Use redundant power and devices: Dual power supplies, spare encoders, and backup controllers reduce downtime.
• Record locally as fallback: Simultaneously record program outputs on a local recorder.

6. Security and access control

• Segment the NDI network: Restrict access to production VLANs from general users.
• Limit controller access: Use role‑based access or local network ACLs to prevent accidental changes.
• Keep firmware/software updated: Apply patches for stability and security improvements.

7. Monitoring and maintenance

• Use monitoring tools: Track stream health, packet loss, and latency regularly.
• Log events and changes: Maintain a changelog for routing presets and configuration edits.
• Schedule regular maintenance windows: Reboot devices and update software during planned downtime.

8. Workflow and team practices

• Standardize naming conventions: For sources, recordings, and presets to avoid confusion.
• Run rehearsals with the controller: Practice routing steps and preset recalls before live events.
• Document procedures: Create quick reference guides for common tasks and troubleshooting.

9. Troubleshooting quick checklist

1. Verify physical network connections.
2. Confirm IP addressing and discovery on the same subnet.
3. Check switch settings (IGMP, multicast, QoS).
4. Reduce quality to test bandwidth constraints.
5. Restart controller service/device if needed.

10. Quick configuration tips

• Use QoS for priority streams.
• Enable multicast only when necessary.
• Cache frequently used presets locally.

Conclusion

Applying these NDI-CONTORLLER best practices — focusing on network reliability, clear device organization, performance tuning, and robust backup plans — will make your live productions smoother and more resilient. Rehearse procedures, monitor actively, and keep configurations documented to minimize surprises during shows.
