Is there a way to know? Also, if you are using scan converter is there a way to know? Thanks in advanced, Fish

Scan Convertor only creates full NDI. NDI-HX is only created by devices with hardware encoders, like the Newtek Spark or Kiloview interfaces or Newtek and PTZ Optics cameras. There may be an iOS camera app that creates NDI-HX. I usually look at the stats for the port on my switch. If it's passing > 20 Mbps you know its not NDI-HX.

So it gets harder to say just by the bandwidth if it's HX or not. Maybe there is more details available in the Newtek NDIanalysis software. I haven't used it so far and have no experiences with it, sorry.

Yes, even for v4.5 of NDI - there is no software encoding of NDI|HX available in the NDI SDK (for Windows).

However, Screen Capture HX requires access to NVENC on an nVidia GPU. So, you would be reducing the resources otherwise available for handing outbound streams.

Last year I ran into some problems with a Birddog stuttering when sending multiple feeds to different receivers. I switched to multicast, saves a lot of bandwidth! Every feed is only send once, even if you use a feed on 10 inputs in Vmix, Studiomonitor or different receivers. cheers, Mark.
