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.
  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.
