 Blur the input video without impacting the outlines.
 
-This filter accepts parameters as a list of @var{key}=@var{value} pairs,
-separated by ":".
-
-If the key of the first options is omitted, the arguments are
-interpreted according to the syntax:
-@var{luma_radius}:@var{luma_strength}:@var{luma_threshold}[:@var{chroma_radius}:@var{chroma_strength}:@var{chroma_threshold}]

 A description of the accepted options follows.

+Set the luma radius. The option value must be a float number in
 the range [0.1,5.0] that specifies the variance of the gaussian filter
 used to blur the image (slower if larger). Default value is 1.0.

+Set the luma strength. The option value must be a float number
 in the range [-1.0,1.0] that configures the blurring. A value included
 in [0.0,1.0] will blur the image whereas a value included in
 [-1.0,0.0] will sharpen the image. Default value is 1.0.
 
 @item luma_threshold, lt
+Set the luma threshold used as a coefficient to determine
+whether a pixel should be blurred or not. The option value must be an
+integer in the range [-30,30]. A value of 0 will filter all the image,
+a value included in [0,30] will filter flat areas and a value included
+in [-30,0] will filter edges. Default value is 0.
