Thank you so much for your reply. Look forward to whenever it does get integrated and totally get that it might be awhile. I have work arounds for now.
Unfortunately, the Syphon NDI apps don't do NDI HX. Currently the syphon apps only do regular NDI which works great for iPhones but not the new HX hardware that NewTek has put out.I might try to bug them and see if they will add. Sienna has added it to their NDI monitor at my request so who knows.
In case anyone is interested, I have tested and am using both the NewTek spark and their NDI PTZ camera. Both work great. Currently running over 250 ft of ethernet cable. No issues. Worked pretty much right out of the box. Very low latency (at least for me). Helping me move beyond my various analog to digital convertors. And the PTZ camera is really great quality. Expensive but can imagine using it in performance a lot.
