CONFIGURING THE SD APERTURE CONTROL
The precise definition of "active region" for an SD input signal may vary. This is due to the fact that 525i
signals have been defined with slight differences in different standards. The SD Aperture control allows
the user to set the exact pixels and exact lines that are used to define the SD Clean Aperture and the SD
Production Aperture. Both the Clean Aperture and the Production Aperture are independently definable.
The user may define whether to use the Clean Aperture or the Production Aperture to determine the pixel
aspect ratio for conversions.

Selecting the SD Aperture control
The AP Aspect Ratio Source control selects whether the Production Aperture or the Clean Aperture is
used when converting input signals.
