BDOF (Binary Depth Of Field) is a Post-effect file that controls effects like focus, sharpness and blur in tracks. It is always seen in the "./posteffect" folder inside an U8 file.

There is unused code that allows the usage of a secondary BDOF file, named posteffect.bdof_demo. This one has the same format as a normal BDOF file, and it seems to be used only in the course introduction if present.
