MatchDef Input Conversion
MatchDef Input Conversion
When MatchDef Mode is selected, the Modular I/O buttons report the current Mode,
Engineering Name of the input, Suite, Output Name, input format and crop status for the
input of the selected pair.
The currently operating video standard is shown in the Frame Operating Mode status
display on the upper right portion of the menu.
Auto Line-Rate Enable –
When on, the system detects the input video format and
automatically chooses the appropriate line rate for the selected input. One frame of video is
required for detection. If the incoming video signal format changes, one incorrect frame of
video will be displayed. When Auto Line-Rate Enable is on, the Line Rate selection buttons
below are inactive.
Note:
Choosing the correct frame rate manually can often resolve a noisy
signal on an incoming source.
When Auto-Line Rate Enable is off, the conversion format for the currently selected input
can be chosen from the Line Rate selection buttons in the right pane ( 4K SDQS, 4K 2SI,
2160p, 1080p-A, 1080p-B, 1080p, 1080sf, 1080i, 720p, Std Def 4:3, Std Def 16:9 ).
Controls for Scale/Sync, Letterbox, Pillarbox, H-Center Cut and V-Center Cut are displayed,
depending on the format selected. These controls are identical to those used for SetDef.
The
Sync/Scale
button behaves the same as the SetDef
Scale
button, but also employs
frame sync circuitry.
