OG-US-4000 User Manual
Crop Tab:
The cropping function allows selecting a portion of
the incoming video image to be scaled to the
outputs. One purpose that cropping can be used
for is undoing a pillar-boxed or letter-boxed image
by selecting only the desired image portion.
The numbers chosen in the configuration
parameters relate to the resolution of the incoming
video. Since the maximum input resolution for the
OG-US-4000 is 1920 x 1080 (1080p), the sliders
include all numbers up to this maximum. The
number you choose will relate to the incoming
resolution, not necessarily these maximums, and
must therefore be numbers less than the incoming
resolution. If the number is greater it is ignored.
