Frame Delay #
When Framesync is enabled, specifies the
smallest amount of latency delay (frames
held in buffer) allowed by the frame sync.
The frame sync will not output a frame
unless the specified number of frames are
captured in the buffer.
The operational latency of the frame sync
is always between the specified minimum
latency and minimum latency plus one
frame (not one field).
Due to card memory limits, the maximum
available Minimum Latency Frames is
related to the output video format selected.
When using this control, be sure to check
the Report Delay field to make certain the
desired amount of frames are delayed.
Video Delay
(read-only)
#ms / # frames # lines
Scaler: #ms
Reports the delay where:
•
#ms represents the total video delay
(frame sync delay + scaler delay)
• # frames # lines represents the delay in
the frame sync
• Scaler: #ms represents the delay in the
scaler
Lock Status
(read-only)
#
Displays the current framesync status
reference source.
a. Offset advance is accomplished by hold-off of the reference-directed release of the frame, thereby effectively advancing
the program video relative to the reference.
