Conversion Settings

The Aspect Ratio Conversion control selects the aspect ratio conversion that the module will perform.
It is important to understand that this control will have no effect when the AFD Input Enable control is set
to ENABLE. When the AFD Input Enable control is set to ENABLE, inbound AFD metadata in combination
with the settings selected within the AFD ARC control tab governs all aspect ratio conversions.
The Aspect Ratio Conversion control is operational when the AFD Input Enable control (within the AFD
control tab) is set to DISABLE or when inbound AFD metadata is missing and the LOSS OF AFD MODE
control (within the AFD Control tab) is set to DEFAULT ARC.
There are numerous pre-defined aspect ratio conversions as well as the ability to define custom aspect
ratio conversions. When the User Aspect mode is selected, the user can set input image cropping and
output image size on a pixel-by-pixel and line-by-line basis. The VLPRO interface for the Aspect Ratio
Conversion control is shown in Figure 7-42. Note that a pictorial representation of what each individual
option actually means will be presented just to the right of the Aspect Ratio Conversion control drop down
menu.
