Note:
• Values in bold or ( ) are factory default settings.
• The “Chromakey Setup” feature only works with Inputs 1 & 2. Input 1 is always the
background video and Input 2 is always the top layer with the key applied to it. The
part of Input 2 that is to be keyed out (removed) should, ideally, be a single color that
is not used anywhere else in the source signal. Typically this is accomplished by using
a special blue or green screen behind the recorded video subject. The Red, Green,
and Blue key values should be set with as small a range between the minimum and
maximum as possible while still maintaining a clean key to help avoid accidental removal
of normal video content. When Input 1 or 2 has no live source a warning message will
appear on the OSD.
• Consult the OSD (“Ethernet Steup” menu) to view the current IP settings if necessary.
An Ethernet re-link is required after every IP change.
