Production Aperture
Selecting the Production Aperture touch button allows the maximum possible
image area that can be supported by the video standard. However due to
filtering and other operations, this method is prone to edge-related arti-
facts.
Clean Aperture
Selecting the Clean Aperture touch button reduces the image slightly to
remove any edge-related artifacts and centers the image so there will be an
equal number of pixels within the clean aperture to the left and right of the
center point.
