FS4 Frame Synchronizer/Converter v1.1
Figure 31. SD Aspect Ratio Conversion Illustrations
6 Upconvert Mode
These parameters select the type of upconversion the Video Processor performs on the
selected input. This parameter has an effect only when the input has a narrower aspect
ratio than the output (SD > HD, HD > 2K). When converting from 2K, the selections do not
precisely describe the resulting picture. For example, 4x3 pillar is not precisely 4x3, and
14x9 is not precisely 14x9. However, picture scaling is such that the visual effect closely
resembles an SD-to-HD upconvert.
NOTE:
Any Custom Size/Pos values (only available in Four Channel Mode) will be applied on top of
this settings.
