Mira 4-Channel Server Video+Key Pairs
Use this procedure to configure Mira with video+key (VK) paired channels. The RS422 serial control port is only on the “video” channel.
Each VK channel pair can be used as either a recorder or player (
a given VK channel cannot record and play at the same time ).
Mira 4-Channel Server
To open the Mira Engineering Setup window shown below, perform the procedure “ Launching Mira Engineering Setup Utility ” found on page 173 above.
1. Click “ Channels ” tab.
2. Click radio button for desired VK channel pairing on (ChA-ChD) group of video channels.
3. Select radio button for desired output on “Key” channel when a “video-only” clip (clip without a key image) is loaded into the
“VK” channel pair.
Normally, “ output white on the key output ” is selected, so video clips without a key image will be visible through a
downstream keyer if the “key” is “on” in this keyer.
4. Click to accept changes.
