Synchronizing Audio and Video Equipment
Avid systems require synchronization when inputting audio and video. A
synchronization signal for analog audio and analog video is generated
internally by the Avid Mojo DNA from one of the following three sources:
•
Internal
— The signal is generated by the Avid Mojo DNA internally.
This signal cannot be sent outside of the Avid Mojo DNA.
•
Incoming video signal
— The sync signal is generated from the
incoming video: component, composite, or S-Video.
•
Video Reference IN (Ref)
— The sync signal should be used when
you are capturing analog audio only. It should be generated from the
incoming signal (black burst generator [BBGen] or house sync). If
there is no sync connected to REF, the internal sync is used by default
to sync the incoming audio.
n
By default, the sync signal is generated from incoming video whenever you
capture analog video. Depending on the configuration of the audio and
video equipment attached to the Avid Mojo DNA, you might need to use a
black burst generator or house sync; for example, when you perform an
Insert Edit.
Power-On Self-Tests
The Avid Mojo DNA runs power-on self-tests (POSTs) to determine if the
box and the board within the box are operating properly each time you turn
it on.
If a failure occurs when running a POST, the Clip LED (see
blinks steadily once a second. Also, if the Power LED does not light after
you connect the Avid Mojo DNA to the power adapter, the Avid Mojo
DNA is not capable of running diagnostics and is not functioning properly.
If possible, try another power adapter. If the Avid Mojo DNA does not
work with a different power adapter, replace the Avid Mojo DNA.
