Setting up HDMI/SDI output

+To turn on HDMI/SDI output, right-click on the live view and
select the output card. (Equivalently, you can access the same functionality
from the *Video* menu in the regular menu bar, or you can give the
*--output-card=* parameter on the command line.) Currently, this is supported
A video mode will automatically be picked for you, favoring 59.94 fps if possible,
but you can change the mode on-the-fly to something else if you'd like,
as long as the resolution matches with what you've set up at program start.

+Unsynchronized HDMI/SDI output
+------------------------------
+
+By default, whenever HDMI/SDI output is active, the output card will be the
master clock; you cannot change it to any of the input cards. This also means
that the frame rate you choose here will determine the frame rate for the
stream.
+In Nageru 2.1.0 or newer, you can use the flag --output-card-unsynchronized
+to counteract this (there is currently no way to do it from the GUI).
+This is for if you want just a monitor output without synchronizing
+your entire stream chain to the output card (ie., you want to keep
+some other camera as the master). Sound support is untested, and is
+probably going to crackle a fair bit.

A note on latency
-----------------
In order to optimize latency, it can be useful to measure it, but for most
people, it's hard to measure delays precisely enough to distinguish reliably

tools that will help.
The most direct is the flag *--print-video-latency*. This samples, for every
