7. To check the installation has been successful, go to the Apple menu and
choose System Preferences. Click on the Displays icon and then on
the Arrangement tab. You should see an extra display which represents
the extended desktop feature of your DeckLink card. The size of the
DeckLink display will appear different to your computer display and may
be a NTSC or HDTV resolution.
8. Select where sound is routed when playing and capturing QuickTime™
movies. To do so, go to the Apple menu and choose System
Preferences. Click on the Sound icon and then on the Output tab.
• Select DeckLink’s “SDI Digital Audio” to output audio channels
1 to 8.
Click on the Input tab and you will see 2 or 3 options related to your
DeckLink card. Due to a current limitation in QuickTime™ in Mac OS
X™, it is currently only possible to input 2 audio channels at any one
time. You will need to specify which audio input you wish to use from
the following options. The settings in Final Cut Pro™ override these
settings and can be set independently to these settings.
• “SDI Digital Audio” will input channels 1+2.
• “SDI Digital Audio (Ch 3+4)” will input channels 3+4.
• “AES/EBU Digital Audio” will input channels 1+2 through the
SPDIF/AES input of the DeckLink HD Pro.
Note: “SDI Digital Audio” should be chosen even when using analog audio with
cards such as the DeckLink SP and DeckLink Extreme. Analog convertors on
the analog DeckLink cards ensure the audio is converted to and from analog or
digital as required.
