Description / Function
Sets the pixel rate in pixels (Machine) or microseconds
(Time) of the format.
The horizontal line rate of the format. The HRAT is the
fundamental frequency in the 882. Parameter: HRAT.
Tune The tunning value of the base frame rate (base/tune) for
NTSC color broadcast compatibility. The tuning value is
base/1.001.
Base The base frame rate.
The number of active pixels (machine) or microseconds
(Time) of the horizontal video. Parameter: HRES.
The number of active pixels (Machine) or microseconds
(Time) of the horizontal video. This parameter is
calculated.
The total number of active pixels (Machine) or
microseconds (Time) of the horizontal video. The total is
the sum of the Active and Blanking. Parameter: HTOT.
The number of pixels (Machine) or microseconds (Time)
in the blanking preceding the horizontal sync pulse.
Parameter: HSPD.
The number of pixels (Machine) or microseconds (Time)
of the horizontal sync pulse. Parameter: HSPW.
The vertical frame rate of the format. Parameter: VRAT.
The number of active lines (machine) or milliseconds
(Time) of the vertical video. Parameter: VRES
The number of active lines (Machine) or milliseconds
(Time) of the vertical video. This parameter is
calculated.
The total number of active lines (Machine) or
milliseconds (Time) of the vertical video. The total is the
sum of the Active and Blanking. Parameter: VTOT.
The number of lines (Machine) or milliseconds (Time) in
the blanking preceding the vertical sync pulse.
Parameter: VSPD.
The number of lines (Machine) or milliseconds (Time) of
the vertical sync pulse. Parameter: VSPW.
Indicates that the value in the field is calculated by the
Format Editor.
Indicates that the value in the field is calculated by the
Format Editor, and that the new value has replaced the
value previously in the field.
