Common Web Presenter 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 →
Want H.265/HEVC streaming to YouTube
Likely cause: HEVC support was added in the 3.4 firmware; older firmware only offered H.264, so the update is what enables it.
- Step-by-step fixGet the fix →
Controls freeze or unit locks up when switching sources
Likely cause: The switcher expects a locked, consistent reference; a mid-stream frame-rate change can stall processing until inputs match.
- Step-by-step fixGet the fix →
Fan runs constantly / unit gets warm
Likely cause: Continuous active cooling is by design for the encoder SoC; airflow, not silence, is the requirement.

How do I tell if the network is keeping up with the stream
Likely cause: The built-in bitrate/cache graphs are the unit's health readout; rising cache is the leading indicator of an under-provisioned uplink.

Intermittent AV (audio/video) sync error after input signal loss (4K)
Likely cause: The desync was a firmware bug in the signal-reacquisition path; 3.5 corrects it, so updating is the fix rather than a workaround.

Need to change streaming protocol (RTMP vs SRT) or codec (H.264 vs H.265)
Likely cause: Blackmagic exposes advanced streaming parameters through an editable XML rather than the GUI; loading a custom XML reconfigures protocol and codec.

No ethernet available — stream over a phone / mobile internet
Likely cause: The USB-C port doubles as a phone-tethering data path; 3.4 patched compatibility with newer Pixel USB tethering.
- Step-by-step fixGet the fix →
Stream stutters, drops, or the cache fills to 100%
Likely cause: The unit buffers to internal cache when uplink < encode bitrate; sustained fill = insufficient/limited upstream, so matching bitrate to real uplink clears it.

Computer doesn't detect it as a webcam
Likely cause: UVC devices need a data-capable cable and enumerate OS-wide; if the OS camera app sees it but your streaming app doesn't, the problem is app configuration, not the unit.
