Detailed Setup and Configuration
Delays, Latency and A/V Sync
Latency through ARC varies depending on which inputs and outputs are used and whether or not SRCs are enabled. In any case,
any latency will result in the processed audio trailing the video by that amount at the SDI output.
Figure 6-7 – Delay menu
To compensate for that latency and avoid lip sync issues, an SDI video delay is provided in the Delays sub-menu of the I/O
menu (A). Click on the millisecond and/or microsecond fields in the Video Delay section (B) and type in the required value.
If the output needs to be delayed by an even frame (the value of which will vary depending on frame rate), simply enter that
number.
Note:
Entering an even frame value will result in a situation where it is necessary to add additional audio delay to
the AES67 and AES-3 outputs so that they match timing of the SDI output signal. This can be accomplished
by setting the
Audio Delay (C) to a value equal to the difference between a full frame and the latency of the
unit.
