Size and Crop tab
The Size and Crop tab (Figure 48) has two functions:

It sets the default output size, whether or not cropping is enabled.

It enables and disables cropping, and sets the cropping rectangle.
The default output size is the video size that appears in the DirectShow pin properties dialog as the
default choice. It is a pathway for setting a custom or nonstandard video size in applications that do
not have a custom video sizing controls built into them.
Cropping means removal of unwanted video around the edges of the incoming image. For example,
if the incoming video is letterboxed, with an aspect ratio wider than 4:3, you can crop away the
black slivers at the top and bottom of the image and capture just the active portion.
Changes made on this page apply to all video preview and capture pins on the currently selected
device.
