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

The reference width and height represent the full uncropped size of the incoming video. Your crop settings are interpreted relative to this reference size. For example, if you are capturing 525-line video, with a reference size of 640 x 480, and your crop rectangle is (0, 0, 640, 480), and then your video is effectively uncropped. But if you are capturing 625-line video, with a reference size of 768 x 576, the same (0, 0, 640, 480) crop specification truncate the right and bottom edges of the video.
