6.20. SD APERTURE CONTROL TAB

The precise definition of "active region" for an SD input is sometimes unclear. This is due to the fact that
SD signals have been defined differently in various 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.

6.20.1.1. Aperture Aspect Ratio Source
The Aperture Aspect Ratio Source control selects whether the Production Aperture or the Clean
Aperture is used when converting input signals.
Production Selects the Production Aperture to be used when converting input signals.
Clean Selects the Clean Aperture to be used when converting input signals.
