PiP masks are used to define the areas of a PiP video that should be hidden. Masks created with the PiP Mask Converter are for use only with CyberLink PowerDirector™. Specifically, from within the "Picture in Picture (PiP) Designer" tool.
PowerDirector requires two files for every PiP mask. The first file is an 80 pixel by 60 pixel PNG image file. This file is the “thumbnail” image that appears in PowerDirector’s PiP Designer pick list. It is used only as a visual representation of what the mask will look like.
