Format Fixed by Video
The options in the field “nnx” for the Video channels are defined by the Video format of the
selected Video channel. These options are for information only, and cannot be changed in this
menu. Sub-field “nn” describes the frame rate, and “x” describes the scanning system:
e.g.
Format Fixed by Video 50i
e.g.

Format
This menu item allows the user to select the required format for the LTC output they are operating
on.
The options in the field for the LTC channels are limited to: 30p, 29.97p, 25p, 24p and 23.98p
where field describes the frame rate, and the scanning system.
Running Time
This menu item displays the current time on the selected Video Output or LTC Timecode channel,
or the SPG Time or UTC DateTime menus. This time display includes any offset that has already
been entered for that channel.
The field “hh:mm:ss:ff” displays hours, minutes, seconds and frames in the 24-hour format.
Where the Running Time relates to a Video Output or an LTC Timecode channel, the separators
between the sub-fields change, depending on the format selection:
Offset = S 00:00:00:00
This menu item allows the user to offset the time on the selected Video or LTC Timecode channel
with respect to SPG Time.
The field “00:00:00:00” is used to add / subtract time to / from SPG Time in the selected Video or
LTC Timecode channel. The sub-fields in the field “00:00:00:00” represent hours: minutes:
seconds: frames. When sub-fields are adjusted, the corresponding fields in “Running Time”
reflect the changes.
Each sub-field is edited individually. A highlight cursor is displayed showing which sub-field is
active and hence editable in the field.
These sub-fields always display any offset that has been entered by the user.
If the offset time is zero or positive, a plus sign is displayed (as above); if the offset time is
negative, a minus sign is displayed.
Offset = UTC + 00:00:00:00
This menu item allows the user to offset SPG Time with respect to UTC Time.
This is where the user should enter their current time-zone offset from UTC. This offset should
not include any daylight saving offset that may be in force - Daylight Saving adjustments are
handled separately (see below).
