Changes made with this control take effect
immediately – the Apply button really has no
function on this tab. If video is running and a
standard is selected that does not match the
incoming signal, the video is likely to freeze or
glitch until the signal matches again.

The Video Input control (figure 7) is a drop list
for selecting the video signal source. The inputs
shown on the list are tailored to the inputs
available on your hardware.
The Video Input control performs about the
same function as a crossbar filter attached to the
capture filter’s Analog Video In pin.
It has one additional control, however, the
Bypass Color Correction checkbox that is enabled
whenever a digital input is selected. When this
box is unchecked, video brightness, contrast, and
saturation can be adjusted using the controls on
the Video Proc Amp property page. When this
box is checked, these controls are bypassed and
the driver does not modify the color settings.
The read-only button marked Video Present
shows whether the hardware is detecting a video
signal on the currently active input. This control
is updated only when you make a change to
the Video Input or Video Standard and click the
Apply button.
The Video Standard control group is the same
as the control on the Video Decoder tab. The
North American standard is NTSC. The Japanese
standard is NTSC-Japan. The five PAL standards,
B, D, G, H, I are almost identical to each other,
and are treated the same way by the Osprey
driver. The driver also supports SECAM video.
Refer to Video Driver Topics, Video Standards
and Sizes, for more information.
Changes made to these settings apply to all
video preview and capture pins on the currently
selected device. If you have multiple Osprey
cards, set the input individually for each of them.
