achieve the best results. You can compensate for a large
change to one by making a large change to the other, but
setting both offset and gain to high values can result in poorer
video quality.
Gain
Use the offset and gain controls together to optimize image
quality. Increasing gain amplifies weak signals but also
increases noise. Balance offset and gain to achieve the best
quality image. You should adjust these settings by the
smallest values possible to achieve the best results. You can
compensate for a large change to one by making a large
change to the other, but setting both offset and gain to high
values can result in poorer video quality.
Aspect ratio
Set the aspect ratio of the captured image. The default aspect
ratio is 4:3. You can change the aspect ratio to wide mode so
that the VGA Broadcaster Lite device can accurately capture
wide aspect ratio modes.
It's not always possible for the Epiphan device driver to
distinguish between video modes when they have the same
number of rows, for example, 1024x768 and 1280x768. You
can change the aspect ratio to Wide Mode if you want the
driver to choose wide video mode in these situations.
