Parameters
Argument
Description of Command Syntax
F=rate
Set the output Rate. For interlaced video, this is the Field Rate. For progressive video it is the
Frame Rate. The following values can be used for
rate
Auto
23.98
24
29.97
30
47.95
48
50
59.94
60
- Automatically match the main input
PF=rate
Same as for
Field/Frame
parameter
Set a Preferred value for the Field / Frame rate. The preferred value may be
used to set the output mode if the F=mode parameter is set to auto and the
main input signal is not present.
Notes on using the Output Mode Command:
1) It is possible to use the Output Mode command to select combinations of resolution and frame rate that are
not supported video modes. In this case the DX-4400 will ignore the settings and not switch into the
requested mode.
2) If only the resolution is specified, or only the frame rate is specified, then the DX-4400 will match the non-
specified parameter to the main input video if the combination is a supported video mode. Failing that, if the
requested resolution or frame rate is a valid mode when combined with the current operating mode, the DX-
4400 will use that mode. Otherwise the DX-4400 will try the preferred value (if one was specified) or simply
select a value that results in a valid mode. Specifying only one of the frame rate and resolution parameters
may result in the DX-4400 operating in unusual video modes such as 720p30 that may not be supported by
other equipment.
For example, the following command sets the output to 1080i60:
O R=1080i F=60
3.9.3.1 Conversion of Video Formats
The Output Mode Commands can be used to convert video formats, for example 720p video can be converted to
1080i or 1080p formats. Since the DX-4400 does not incorporate a video deinterlacer, it is not possible to NTSC
into a progressive output.
3.9.4 Video Background Color Command
Background Color Command allows you to set the background color for the SDI inputs. Each Saveset has its own
set of Background Color stored parameters. The background color is not visible through the SDI input when the
Alpha Blend is set to 0.
The following commands are two examples of settings a green background for channel 1:
BC1 green
BC1 #000128000
The settable values for the background color listed in the table below.
