Output H Start
and
Output H Stop
define how to scale the cropped
input image horizontally and where to place it horizontally on the output
raster. The image will be stretched to fill the width. (I.e. For 1080i the
range of values are 0 to 1919. The range of values for 720p output is 0
to 1279).
Output V Start/ Output V
Stop:
The
Output V Start
and
Output V Stop
define how to scale the cropped
input image vertically and where to place it vertically on the output raster.
The image will be stretched to fill the height. (E.g. For 1080i, the range
of values are 0 to 539. The range of values for 720p output is 0 to 719).
A pictorial representation of the input image cropping and output image size is shown to the user right
below the slider bars for the custom aspect ratios as shown in Figure 6-14.
