Frame Latency
Specifies the smallest amount of latency allowed by the frame sync. This latency measurement is in
frames of the output video. The frame sync will not output a frame unless the specified number of
frames are captured in the buffer. Minimum latency is three lines and zero frames in all video modes.
The maximum latency is format dependent. The operational latency of the frame sync is always
between the specified minimum latency and minimum latency plus one frame (not one field).
Audio Delay
Specifies the amount of additional audio delay after matching video delay. When the change is under
one and a half frames, the change in audio delay will be applied without interrupting audio. When
changing audio delay more than a frame and a half at a time, there will be a slight audio glitch.
Video Delay
Reports the current amount of video delay in ms.
Reset Frame Sync
Resets the frame sync, clearing any buffered audio and video. You must reset the framesync after
manipulating the horizontal and vertical offset in order re-establish correct audio and video co-timing.
