'''Back to [[VariableBlur#Filters|VariableBlur]] ←'''
== Description ==
:BinomialBlur works by repeating a 5x5 or 3x3 kernel based on pascals triangle multiple times to blur the image.
:With a variance above 1 the result is very close to a true Gaussian blur and much faster (for variance below ~30).
 

== Requirements ==
:- [[FAQ_different_types_content#How_do_I_recognize_progressive.2C_interlaced.2C_telecined.2C_hybrid_and_blended_content.3F|Progressive]] input only
:- Supported color formats: [[YV12]]

== Examples ==
BinomialBlur with default values:
[[AviSource]]("Blah.avi")
BinomialBlur(varY=1.5, varC=1.5, Y=3, U=2, V=2, useMMX=true)
