BMD Video I/O Not Initializing

Flame Hardware Questions
,
1

Flame is seeing the BMD video hardware (UltraStudio 4k Extreme 3) and I can see it setting the preview format and timing, but it doesnt send picture to the broadcast monitor. The Console in flame seems to indicate it’s stuck trying to initialize…

Any thoughts?

Flame v: 2026.2.1
Desktop Video: v16.0.1
Mac OS: 26.5
System: MacPro 7,1
2.5 GHz 28-Core Intel Xeon - AMD Radeon Pro Vega II Duo 32 GB

Thank you!

I don’t think Desktop Video 16 is qualified for Flame, try using 15.3.1.

Correct, there’s actually a bug. That was discussed in the latest Logik Live this weekend.

Yepppp - 15.3.1 fixed it.

Thanks!!
