So, a little further on the details side ... consider that a single VMC1, without any outboard modules or external software - i.e., without even considering even our free NDI tools (which includes NDI Connect that can give you more SDI/HDMI inputs or outputs) - has >39 outputs ... 4 HD-SDI and 35 fully independent NDI outputs (and more, as I'll explain).
The four SDI outputs and the first four NDI outputs can be display mixed sources (i.e., the Switcher or any M/E) or any other Switcher source. All hardware sources, all four DDRs, and still Buffers are always available as NDI sources. And 8 special NDI outputs have been provided that can be freely hot-punched in the UI, and have access to all four mixed outputs as well as all hardware and NDI inputs connected to the Switcher, the DDRs, and still Buffers. Keep in mind, too, that what we don't even bother to include things that most competing systems would count as 'outputs' in this list - recorders, streaming, and multiviews.
Let's just say that this thing has more outputs than pretty much anything you can name even without adding VMC1 OUT modules (each of which adds 4 HD-SD1 outputs). And the greater number of them are available across your network. This is just insane.
