• Source Priority

Selects the priority assigned to each supported external formats, and
internal Free Run in the event the preferred source is unavailable.

Source Priority 1 thru Source Priority 4 select the preferred format to be
used in descending order (i.e., Source Priority 2 selects the second-most
preferred format, and so on. See example below.)

Note: Reference VITC selection uses reference source as selected on the

Reference tab (see Reference Select Control (p. 3-16)).

Note: Disable Output setting should be used with care. If Disable Output is selected with alternate intended format(s) set as a lower

priority, the card will indeed disable all timecode output should the ordinate preferred format(s) become unavailable.

Typically, choices other than Disable should be used if a timecode output is always desired, with Disable only being used to
remove all timecode data.

• Offset Controls

Allows the current timecode count to be advanced or delayed on the output
video.

• Offset Advance or Delay selects offset advance or delay.

• Offset Field delays or advances or delays timecode by one field.

• Offset Frame delays or advances or delays timecode by up to 5

frames.

Note: Default settings are null, with both controls set at zero as shown.

In this example, Input VITC 1st priority selection selects SDI VITC (received on
SDI input) over reference VITC (received on frame reference) regardless of video
input material source to be processed by the card.

The selected timecode source is embedded on the SDI video output (in this
example, 720p) using the selected line number. In this example, if the SDI VITC
on the SDI input becomes unavailable, the card then uses the reference VITC
data received on the frame reference.

(w/ ATC_VITC)

In this example, even though
and ATC_LTC could be
available to substitute for
ATC_VITC not being present,
the card will revert to no
timecode output since the
choice of Disable Output
“out-prioritizes” ATC_LTC
with these settings.

The choices shown here
will allow ATC_LTC to
“out-prioritize” Disable
Output if ATC_VITC is
not available.
