Common TriCaster errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact software is in Ask Roadie.
- Step-by-step fixGet the fix →
An NDI source will not appear / NDI Monitor or the TriCaster does not see other NDI devices on the network
Likely cause: NDI uses mDNS for auto-discovery, which is blocked by host firewalls and does not cross subnet/VLAN boundaries.
- Step-by-step fixGet the fix →
Dante audio into the TriCaster has pops, clicks, or dropouts
Likely cause: Clicks/pops come from clock drift or sample-rate mismatch between the Dante card and the host; a single PTP master plus matched 48k and prioritized PTP traffic keep samples aligned.

How do I install a TriCaster software update?
Likely cause: The installer replaces the live-production application and its prerequisites and must run with admin rights; interrupting the integrity check corrupts the install and forces a restore.

How do I stream to a destination not in the preset list (custom RTMP to YouTube/Facebook)?
Likely cause: TriCaster ships presets that can lag platform changes; a custom RTMP preset lets you point at the current ingest URL/key directly so streams do not fail from stale preset endpoints.

Live stream drops frames, buffers, or stutters on the viewer end
Likely cause: RTMP over TCP needs steady packet timing; CBR with headroom below real upstream prevents the ingest buffer from starving.
- Step-by-step fixGet the fix →
NDI runtime/binaries install hangs on "Installing the latest NDI binaries" or fails to update
Likely cause: The NDI runtime files are locked while any NDI consumer/service is running, so the installer cannot overwrite them until those processes are stopped.

Selecting or importing a clip in one DDR causes audio to drop from a clip playing in another DDR
Likely cause: This was a confirmed defect in earlier 8-5 builds where a media operation on one DDR interrupted another DDR's audio; the 260617 hot fix corrects it.
- Step-by-step fixGet the fix →
TriCaster output needs to be genlocked to house reference / output timing drifts against other switchers
Likely cause: Genlock locks TriCaster output to a common station reference so it aligns with other reference-locked equipment; choosing the wrong reference type (tri-level vs black burst) causes it to fail to lock.
