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 custom video sizing controls built into them.

Pin Select

You can have different setups for the two pins. For example, you could enable cropping on the capture pin but not on the preview pin.

Capture	When you click Capture, the current crop settings for the capture pin
	are loaded, and changes you make apply only to the capture pin, not
	to the preview pin.
Preview	The Preview button works analogously.
Both	When you click Both, changes you make to the crop setup apply to
	both the capture and preview pins. This setting is the default.

Reference Size

The reference size information is always read-only on this dialog tab. The reference size is determined by settings made on other tabs – specifically, the Input tab, where you select a 525-line or 625-line standard, and the RefSize tab, where you select Square Pixel or CCIR proportioning. The read-only text box describes which of these options is currently governing the reference size.
