The Blackmagic Videohub routers problems live-event techs bring to Ask Roadie most (also called Smart Videohub, Smart Videohub 40x40, Universal Videohub, Videohub). Pick your symptom, or describe your own in plain words, and get the likeliest fix first, with the manual page when there is one.
Common Videohub routers errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Videohub drops offline after sitting idle for hours/days (routes still pass, but you cannot reach it to change them)
Likely cause: The Videohub stops sending ARP/keep-alive traffic when idle; an EEE/Green-Ethernet port then powers the link down and drops the device from the switch's table, so controllers can no longer find it even though the crosspoint keeps routing.
- Step-by-step fixGet the fix →
A section of the router goes dark or the unit repeatedly drops offline and needs power-cycling (modular/Universal Videohub)
Likely cause: Partially-seated crosspoint/interface cards make intermittent backplane contact, which shows up as missing outputs or a unit that keeps going offline.

How do I update Videohub software/firmware?
Likely cause: Videohub firmware ships inside the desktop Videohub Setup app; USB is the guaranteed update path and Ethernet updating is locked off until explicitly enabled over USB, which prevents accidental remote bricking.

Intermittent dropouts/sparkles at 12G-SDI (4K) on a Videohub 12G output
Likely cause: 12G-SDI has a much tighter cable-loss budget than lower rates; a run that passes 1.5G/3G will fail at 12G.
- Step-by-step fixGet the fix →
Is there a factory reset? / config is corrupted
Likely cause: Videohub has no reset switch; re-flashing the firmware rewrites the device's software and clears a corrupted configuration, which is the community-standard recovery path.
- Step-by-step fixGet the fix →
Need to route sources/destinations on a 2110 IP network, not just SDI
Likely cause: NMOS IS-04/IS-05 is the discovery/connection standard for 2110 IP; the 10.1 firmware lets the Pro control panels speak it, so the same hardware panels drive both SDI and IP routes.
- Step-by-step fixGet the fix →
No video, or unstable/glitchy video, on a routed output
Likely cause: Bypassing and testing one crosspoint at a time isolates the real fault instead of blaming the router.
- Step-by-step fixGet the fix →
Switching glitches / cuts happen at the wrong time when a reference is connected
Likely cause: Clean vertical-interval switching requires a stable reference locked to the video format; a wrong-rate, unterminated, or noisy reference makes the router switch at the wrong point.
- Step-by-step fixGet the fix →
Control keeps dropping between power-ups
Likely cause: Control clients target the router by IP; a new lease means every panel/app is now pointing at nothing.
