4. Audio Delay
To synchronize an audio signal externally recorded
together with video signal output from the camera,
appropriate delay shown in the table below is required for
phase alignment between video and audio.
The values shown in the Code column are recorded as
Metadata.
The delay amount (from shot untill output) of video varies depending on the
video format. For more information, see “Lip Sync Compensation” on page
137.
When audio is directly connected to the interface box of the camera, the
phase is automatically adjusted and embedded in the SDI signal output.
