This menu option determines the position of the shrunken image on the monitor
screen. This will move an image that is less than the full screen size left/right or
up/down within the monitor’s available screen space. It will not let you move the
image off the screen, so certain values will appear to have no effect (unless you use
a very low Shrink value like 10%).
This item provides a simple way of changing the output screen aspect ratio, to suit
the incoming video signal and final output display size. Use the zoom/shrink
functions for occasions when the aspect ratio is an odd format.
See later section for further details on this item.
This is a feature only present in advanced units only. It greatly improves the method
of frame-rate conversion, by allowing the unit to merge frames together during the
process.
When ‘Off’, the unit will use frame-repetition when converting 50Hz to 60Hz (i.e. it
has to duplicate every 5th frame), or frame-dropping when converting 60Hz to 50Hz
(i.e. it has to drop every 6
th
frame). When ‘On’, smooth blending is applied so that
frames are not lost, but blended together at the appropriate times.
The Flicker Reduction menu item will only appear if you have selected a low
resolution interlaced output such as PAL or NTSC. If you are using CV or YC
outputs, this adjustment may be of interest, particularly when you have line drawings
or similar fine detail. You can choose from four possible Flicker Reduction settings.
You should use as little Flicker Reduction as possible because the Vertical detail will
be softened at the highest setting.
