Output Adjust
This menu contains adjustments associated with setting up the outputs of the unit. Use the up and down
arrows to scroll to the required sub-menu and press the Select/Enter key to enter the sub-menu. The
following sections list the sub-menus.
4.9.1.
Lock Mode
The unit output can be run with a fixed format set under Output Format or locked to a frame
synchronisation signal provided on the dedicated analogue genlock input or SDI genlock input.
The genlock signal must be a video format and must have a vertical rate of 50Hz, 59.94Hz or 60Hz. The
output will be vertically locked to the genlock signal. The phase can be controlled through the menu
system, allowing adjustment for a desired latency.
Genlock status is shown via the front panel status indication on the right-hand side of the screen,
provided it has been enabled on the menu.
There are the two locking options: Auto Format and Frame Synchronize.
With Auto Format the output mode is chosen to be the same as the mode provided on the genlock input
regardless of the setting under Output Format.
Frame Synchronize uses the mode set under Output Format. Locking a HD output mode to a SD
genlock signal or a SD output mode to a HD genlock signal is possible at 50Hz and 59.94Hz when the
genlock signal and frame rate of the mode set under Output Format are identical. The HD output mode
can be chosen to be 720p, 1080i, or 1080p. If the genlock signal and output mode set under Output
Format are both HD or SD the output format and genlock signal format need to be identical to obtain a
lock.
Combinations not supported are reported in the menu status screen accordingly.
4.9.2.
Reference Source
The source for the frame synchronisation signal can be either an analogue bi- or tri-level signal or
derived from an SDI signal which is set through this menu item.
4.9.3.
Reference Offset
When the output signal is locked to the input signal the latency between input video and output video
image is given by the internal processing time which can be several frames or fields. The amount of
latency in frames or fields depends on the set up of the unit and also on the input format, e.g. a
progressive signal needs less processing time than an interlaced signal which has to be de-interlaced
prior to further treatment. The reference offset menu allows to increase the latency.
Vertical
Increase the latency in multiples of lines.
Horizontal
Increase the latency in multiples of pixels.
4.9.4.
Free Run Format
The unit can be set to operate at a fixed output format. The unit is performing time base correction. The
following output formats can be chosen:
480i59.94, 576i50, 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080sf23.98, 1080sf24,
1080sf25, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94, 1080p60.
