TriCaster NDI Feed Dropping Out: Causes and Fixes

Few things are more frustrating than seeing an NDI camera or source disappear from your TriCaster in the middle of a service—especially when the network appears to be working normally. When this happens, churches often assume something is “wrong with NDI” or that the switch has failed. In reality, most cases of a TriCaster NDI feed dropping out are caused by timing, bandwidth, or device behavior—not obvious network outages.

This guide walks through the most common causes and simple fixes churches can apply without redesigning their entire network.

What “The Network Looks Fine” Usually Means (and What It Doesn’t)

When volunteers say the network looks fine, they usually mean:

Internet is still working
Devices still appear connected
No cables are unplugged

NDI, however, is sensitive to issues that don’t break basic connectivity—like brief congestion, device power settings, or timing problems.

Common Cause #1: Short Bursts of Network Congestion

NDI uses steady, high data flow. Even brief spikes in traffic can cause dropouts.

For example, a single 1080p60 NDI stream can use up to around 150 Mbps, so multiple feeds can add up quickly.

What often causes this mid-service

Automatic updates or cloud backups starting
Someone joining the network on Wi-Fi
Multiple high-bitrate NDI sources active at once

Simple fixes

Keep all NDI devices on wired connections
Avoid sharing NDI and general internet traffic on small switches
Disable automatic updates and backups during services
Reduce the number of simultaneous high-bitrate NDI streams

Common Cause #2: Source Device Power or Sleep Settings

The TriCaster may be fine—the NDI source may not be.

Common culprits

Laptops dimming screens or entering sleep mode
PTZ cameras using low-power or idle settings
Computers throttling network adapters to save power

Quick checks

Disable sleep and power-saving modes
Keep source devices plugged into power
Avoid running critical NDI sources on battery power

Common Cause #3: Network Hardware Struggling Under Load

Not all network gear handles real-time video equally well.

Warning signs

Dropouts only happen during busy moments
Rebooting equipment temporarily “fixes” the issue
Problems increase as the service goes on

Practical improvements

Use a quality gigabit switch for NDI traffic
Avoid daisy-chaining multiple small switches
Keep network layouts simple and predictable

For larger NDI systems, a managed switch with recommended NDI settings may be worth considering—but small setups can still work well when kept dedicated and clean.

Common Cause #4: Discovery vs Stability Confusion

NDI is excellent at finding sources—but discovery isn’t the same as reliability.

Helpful habits

Lock in NDI sources before the service starts
Avoid rescanning or reconnecting mid-service
As a pre-service routine, restart NDI source devices and the TriCaster before people arrive

This clears lingering states and reduces mid-service surprises.

What Rarely Fixes NDI Dropouts

Before assuming the worst, avoid jumping to these conclusions:

The TriCaster is defective
NDI is unreliable by design
A faster internet plan will fix it

NDI operates on your local network, not your internet speed.

Final Thoughts

When a TriCaster NDI feed drops out mid-service, the cause is usually hidden network congestion, source device behavior, or bandwidth pressure—not a total network failure. By keeping NDI wired, reducing simultaneous high-bitrate streams, stabilizing source devices, and adopting a consistent pre-service routine, churches can dramatically reduce dropouts. Reliable video keeps volunteers calm—and keeps the focus on worship, not troubleshooting.
