Short explanation of the available options
==========================================

The default values of the deinterlacer are the one which aparently
worked best for me in my tests. However, different video material
might need different settings, so here's a quick overview over the
available options.

Swap fields first:
------------------
Will deinterlace in even odd rows instead of in even rows. Useful for
some broken capture devices.

Threshold:
----------
Specifies the largest difference until a deinterlaced pixel is considered
wrong. Try to set this value as high as possible while it still removes all
interlacing in your video.

Blend fields:
-------------
This option will blend both fields together instead of interpolating
between them. This results in smoother images but on the other hand, you'll
get some "ghosts" in movement.

Show interpolated areas as white:
---------------------------------
Use this for adjusting the above threshold. If this box is checked,
every interpolated pixel will be drawn white. While this is good in some
interlaced areas, make sure there aren't too many white pixels in
non-interlaced parts of the image.

Edge detection:
---------------
Setting a low value will keep more edges intact. However, setting this
option too low will result in some areas being still interlaced, so try
to find a value as low as possible while still maintaining a completely
deinterlaced image.
Note: This option has no effect if you enable "Blend fields" !

Edge detection threshold:
-------------------------
Whenever edgedetection encounters a horizontal line, this value comes into
account. Those areas are a bit difficult to handle cleanly, however setting
this to a low value will interpolate more of those areas. (Note: this option
is new in 0.8b, and not yet heavily tested. It's best to try for your own,
as it might possibly be, that the optimal setting is very specific to the
source material.)
Note: This option has no effect if you enable "Blend fields" !

Min. width for interpolation:
-----------------------------
This value specifies the minimum amount of pixels next to each other
that need to be interpolated. This is used to eliminate wrongly interpolated
single spots in the image. A higher value will ignore more interpolated
areas but will also tend to leave some interlacing still visible.
