Interlace Mode
(Encode 1 to 3 Only)
Follow Input

Progressive HQ
Interlace
This allows the user to specially handle interlaced
input. “Follow input” is the default option – it will
leave interlaced input as is.
“Progressive” will convert the interlaced input to a
progressive picture. This can be used to improve
quality if playing back on a PC player.
“Progressive HQ” activates a special high quality
deinterlacer. Since this requires extra cycles, this
is available only for D1 input and below.
“Interlace” can be used to make progressive input
interlaced.
This value must be the same for all three channels
in Encode 1 to 3 Mode. If an attempt is made to
change it on one channel while the others are
running, a warning message will appear that the
other two channels need to be stopped so that all
three channels can have the same configuration.
Noise Filter
On
Off
Turns on an optional noise filter. This helps reduce
noise in high-detail areas (for example, around
text). The tradeoff is some detail may be lost when
the filter is turned on.
