:0: nearest-neighbor sampling, fast but incorrect

:1: linear interpolation (default)

``unsharp[=l|cWxH:amount[:l|cWxH:amount]]``

unsharp mask / gaussian blur
|

|

``l``
|

Apply effect on luma component.
|
||||
``l`` is for the luma component, ``c`` for the chroma component. ``x``/``y``
|
||||
is the filter size. ``a`` is the amount.
|
||||
|
||||
``c``
|

Apply effect on chroma components.

``<width>x<height>``

``lx``, ``ly``, ``cx``, ``cy``

width and height of the matrix, odd sized in both directions (min =

3x3, max = 13x11 or 11x13, usually something between 3x3 and 7x7)

``amount``
|

``la``, ``ca``
|

Relative amount of sharpness/blur to add to the image (a sane range
|

should be -1.5-1.5).

:<0: blur

.. note::

Deprecated. Use libavfilter's ``unsharp`` filter through ``--vf=lavfi``
|
||||
instead.
|
||||
|
||||
``swapuv``
|
||||
Swap U & V plane.
