VIDEO STANDARD
The Video Standard option is an important one, since it
determines the framerate ‘family’ that the hardware is able to
access, and thus what formats will be available for input and
output. Options are NTSC and PAL.
GENLOCK
The Genlock input on NC1 IO's backplane is for connection of a
‘house sync’ or reference signal (typically a ‘black burst’ signal
intended specifically for this purpose). Many studios use this
method to synchronize equipment in the video chain.
Genlocking is commonplace in higher-end production
environments, and genlock connections are typically provided
on professional gear.
If your equipment allows you to do so, you should genlock all hardware sources supplying NC1 IO, and the
NC1 IO unit. To connect the genlock source, supply the reference signal from the ‘house sync generator’ to
the Genlock connector on the backplane.
Note: The unit can use SD (Bi-level) or HD (Tri-level) reference. (If the Genlock switch is disabled, the unit
operates in an internally managed ‘free running’ mode, instead.)
In the Genlock control group, select the format of the reference signal you are supplying.
