Troubleshooting
DashBoard™ shows
Framesync Status error
message in 9067 Framesync
function submenu screen. Specified Minimum Latency
Frames setting exceeds 9067
card buffer space for the
selected output video format 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.

this case, instead apply a positive value that
results in the desired net offset.

Embedded audio contains
Dolby
®
E or Dolby Digital
encoded signal
When a valid Dolby
®
E or Dolby Digital signal (in
accordance with SMPTE 337M) is detected on
an embedded audio signal, gain and polarity
controls are bypassed (even though controls may
appear to be functional). Gain and polarity
controls are not available for this signal type.
