Setting Blackmagic Preferences
Black Video Output
This setting allows DeckLink to output a stable black signal on one video output, while outputting
video on the other output. Black Video Output is used for video referencing a deck when you don’t
have a sync generator available. This allows the stable black video output to connect to the deck,
and then by setting the deck to “input reference” you can operate without a sync generator. If
you’re not using this mode, disable this setting to enable audio monitoring during capture.
NTSC setup
The NTSC composite video used in the USA, and some other countries uses 7.5% setup. However
setup is only used in composite video, but is never used in SDI video. Your DeckLink will handle
adding and removing setup from NTSC video automatically for you. The USA and countries that use
7.5% setup should enable this setting; if you’re working in Japan and countries that don’t use this
setup, leave this set to 0 IRE setup. The PAL and high definition standards do not use this setup.
Video Desktop
If your DeckLink card includes the extended desktop feature, this setting allows DeckLink to act
as a display device with the desktop appearing out of the video outputs. This setting allows the
desktop mode to be turned on and off and any change requires a restart. It’s important that you set
the desktop mode to the same standard as your video capture and playback, or you will get slower
switching between capture and playback modes, as the monitors need to re-lock.
If you don’t want to use the Extended Desktop feature, set this option to Black and then restart
the computer.
If you’re adjusting LUT’s on some DeckLink models, set this option to Last Played Frame so you can
observe the effect of any adjustment to LUT’s.
