Works great, as long as you like the defaults!
The “Full NDI” output format looks alright. I didn't try HX2 H.264, but even at the highest possible bitrate (10 Mbps), the HX2 H.265 output looks terrible. As with the resolution selection, I suspect it's letting me pick a different bitrate but is ignoring it and continuing to use the default (1 Mbps).
The app technically has colour temperature selection, but the app just auto-adjusts for whatever you're pointing at when you hit the button – couldn't find a way to manually enter a temperature, so no way to synchronize temperatures between multiple cameras. And the temperature it auto-selected was always way warmer than appropriate.
Really disappointing. Too few NDI camera apps available with explicit, manual stream fidelity settings, so it's a shame this one doesn't work.
