Input BNC Configuration
Many video sources have an associated video source
that contains alpha (transparency) 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.
