Concepts & signal flow
- Cable types & signal flowHDMI 2.0 vs 2.1 — bandwidth, resolutions, and how far can I run it? · I get hum/buzz on a long audio run — balanced vs unbalanced?
- Dante & audio-over-IP networkingDevice stuck in failsafe (default name in red, no audio) · Dante Controller looks different / cannot find menus after updating (4.18)
- DMX / sACN / Art-Net / RDMArt-Net node works but bogs down the network / other gear sees lag · How many fixtures on one DMX line, and how long can the run be?
- General networkingA Dante/AV device came up with a 169.254.x.x address and cannot be seen · Can I run show-critical audio/control over Wi-Fi?
- RF coordination basicsHow do I coordinate wireless mics and IEMs together without them killing each other? · My coordination looks clean on paper but I still get hits — what physical/RF-gain factors am I missing?
- Streaming protocols & NDIBest encoder settings for a reliable RTMP push to YouTube/Facebook/Twitch · How much bandwidth does NDI use and how many streams fit on my network?
- Timecode & syncChoosing between MTC and LTC for triggering, and fixing the small timing offset · Clicks, pops or dropouts on a Dante/AES67 networked audio system
- Video formats & codecs.mov or .mp4 file still won't play even after checking format · Best DXV settings for Resolume, and why DXV only runs fast in Resolume
- Windows & macOS show-machine basicsCapture/streaming app (OBS etc.) shows a black screen on Mac · Desktop/windows rearrange or resolution resets when the projector sleeps, switches, or is unplugged
Streaming
- Ecamm LiveAdding a video clip (MP4/MOV) as an overlay with sound · Audio out of sync / lip-sync off in Ecamm stream or recording
- OBS Studio"Failed to connect to server" when starting stream (RTMP) · Audio out of sync with video (in stream or recording)
- vMix"The current Registration is corrupt" or "invalid class" error at startup · Cannot activate license / "activated too many times"
- Zoom / Teams / Webex (hybrid events)HDMI capture card shows black / "No Signal" and the switcher output won't appear as a camera · How do I get a broadcast-clean multicamera feed into Zoom over the network (NDI)?
Playback & media servers
- MadMapperContent doesn't line up on curved/architectural surface · Crashes on launch / splash screen closes immediately / random flicker to black
- MilluminBlackmagic capture card / live input not detected · Move a Millumin license to another Mac
- NotchBlock will not load — SDK / runtime version mismatch (esp. NVIDIA 50-series) · How do I install/update Notch or run multiple versions?
- PlaydeckA clip stops early and skips to the next clip in the playlist · After disconnecting Remote Desktop (RDP) to a headless PLAYDECK PC, playout/NDI/streams stop or PLAYDECK hangs on reconnect
