@section sab
Apply Shape Adaptive Blur.
The filter accepts the following options:
@table @option
@item luma_radius, lr
Set luma blur filter strength, must be a value in range 0.1-4.0, default
value is 1.0. A greater value will result in a more blurred image, and
in slower processing.
@item luma_pre_filter_radius, lpfr
Set luma pre-filter radius, must be a value in the 0.1-2.0 range, default
value is 1.0.
@item luma_strength, ls
Set luma maximum difference between pixels to still be considered, must
be a value in the 0.1-100.0 range, default value is 1.0.
@item chroma_radius, cr
Set chroma blur filter strength, must be a value in range 0.1-4.0. A
greater value will result in a more blurred image, and in slower
processing.
@item chroma_pre_filter_radius, cpfr
Set chroma pre-filter radius, must be a value in the 0.1-2.0 range.
@item chroma_strength, cs
Set chroma maximum difference between pixels to still be considered,
must be a value in the 0.1-100.0 range.
@end table
Each chroma option value, if not explicitly specified, is set to the
corresponding luma option value.
@section scale
Scale (resize) the input video, using the libswscale library.
