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.

For More Information on...

•Auto-Select keys, refer to the section “Keying Overview” on page 18.

To associate video and alpha inputs:

5.Use the Alpha knob to select the desired input that will provide the alpha (transparency) signal. You can choose from the following:

•None — Do not use an associated alpha signal.

•Lin1 - Lin12 — The selected input is used as an unshaped (linear) alpha source.

•Shpd1 - Shpd12 — The selected input is used as a shaped alpha source.
