Framesync
Provides video frame sync/delay offset control and
output control/loss of program video failover selection
controls.
Note:
Framesync tab has identical independent controls for both Path 1 and Path 2 using the Path 1 / Path 2 sub-tabs.
Therefore, only the Path 1 controls are shown here. Set controls for other path using the respective sub-tab.
• Framesync Enable/Disable Control
Provides master enable/disable of all card framesync functions/controls.
• Lock Mode Select
Selects Frame Sync functions from the choices shown to the left and
described below.
• Lock to Reference: Output video is locked to selected external
reference received on the frame reference bus. (External reference
signal Ref 1 / Ref 2 are distributed to the card and other cards via
the Ref 1 / Ref 2 buses on the frame.)
Note: If valid reference is not received, the
indication appears in the Card Info
status portion of DashBoard™, indicating invalid frame sync
reference error.
• Lock to Input: Uses the selected program video for the path as the
reference standard. Lock To Input Path selects the program video
source which is used for ref.
Note: If Lock to Input is used for framesync, any timing instability
on the input video will result in corresponding instability on
the output video.
• Free Run: Output video is locked to the card internal clock.
Output video is not locked to external reference.
• For cases where minimum latency is desired (no
framesync), Mode should be set to Lock to Input
with Framesync set to Enabled. If Disabled is
selected when using dual paths, severe video and
audio corruption can occur.
• Output Rate Select
Allows frame rate to be outputted same as input video, or converted to
from the choices shown to the left and described below.
• Auto – output video frame rate tracks with input video.
• 23.98/29.97/59.94 – forces standard North American frame rates.
Can be used to convert 24/30/60 Hz camera frame rates to
corresponding 23.98/29.97/59.94 standard North American frame
rates.
• 24/30/60 – forces 24/30/60 frame rates. Can be used to convert
23.98/29.97/59.94 Hz frame rates to corresponding 24/30/60 Hz
frame rates.
