Step 4. At Blackmagic Design window, click on the "Set input" pop-up menu to select the appropriate input type.
The available choices will depend on the input signals that the installed card is able to receive, as different
cards may have different input types. In the case of the Decklink HD Extreme capture card (show below),
the three possible selections are: SDI Video, Component Video, and Composite Video (Y in). Because Mbox
does not use the audio input on the Decklink capture card, the audio type in each of the inputs can be
ignored.
Step 5. Make sure the "When not playing video, send" pop-up menu is set to "Black" as show in the picture above.
Step 6. Close Blackmagic Design window.
