9061 PRODUCT MANUAL
Corrective Action
Reduce the Minimum Latency Frames setting
as specified in the error message to correct the
error.
Note:
Due to card memory limits, the maximum
available Minimum Latency Frames is
related to the output video format selected.
For example, with a 1080i 5994 output, the
maximum setting is 5. For a 1080i film
(2398) output, the maximum setting is 3
(due to the increased buffer space needed
for the slower frame rate). Conversely,
greater maximum settings are allowed for
SD formats such as 525i 5994, where the
practical maximum limit is 13.
Timecode output requires that source and
priority are appropriately selected. Also, video
input must contain appropriate timecode data
and framesync reference.
Refer to Timecode function submenu tab on
page 3-46 for more information.
Use the Audio Offset from Video control to
compensate for video/audio delay.
Refer to Framesync function submenu tab on
page 3-27 for more information.
Negative vertical or horizontal delay values
(using the controls below) should not be used
when using Input Video mode. To add an offset
in this case, instead apply a positive value that
results in the desired net offset.
If analog VITC timecode source contains
7.5 IRE of setup, make certain
Video Signal Controls –> NTSC Contains is
set to 7.5 IRE of Setup.
If this is not done, analog VITC waveform may
not be received and processed by the card.
• Make certain respective control is set to On or
Enabled (as appropriate).
• Make certain each ancillary data item to be
passed is assigned a unique line number (see
Ancillary Data Line Number Locations and
Ranges on page 3-8).
Reduce analog audio level at the source.
Note:
9061 audio gain controls cannot be used to
correct analog input overload condition. The
condition must be corrected at the source.
