Regionalize

Apply subeffects to a region defined by a clip's alpha channel.

This is the mlt filter region

arguments:

File A file whose alpha channel will "shape" the region. The string "circle" is a shortcut but it requires pixbuf with the librsvg loader. The circle is automatically stretched to the region to create an ellipse.

Region Properties may be set on the encapsulated region transition. See "region" transition for details.
