Input BNC Configuration
Many video sources have an associated video source
that contains alpha information. You must configure
the switcher to use the correct alpha source. Once
you associate a video and alpha source, they are
linked and used for Auto-Select keying.
Alpha sources are designated as shaped or linear
(unshaped). Shaped sources convert partial
transparency to either fully transparent or fully
opaque, giving the video signal well-defined edges.
Linear (unshaped) sources use the full range of
transparency in the alpha channel to give smooth
transitions between transparent and opaque areas.
Use linear if you are unsure which setting to use.
Inputs can also be assigned to external devices that
you are controlling from your switcher. Refer to the
Ross Video External Device Setup Sheet
for your
device connection and configuration information.
