Description

A blurring filter that is ususally used to blur the edge mask (the ouput of aSobel).

Syntax and Parameters

aBlur (clip, int "blur", int "type", int "chroma")

clip   =

Input clip.

int  blur = 3

Range: 0 to 100

Number of blur passes over edge mask.

Higher values increase blurring strength. Less passes increase sharpening effect, but can produce major artifacts with high depth and thresh.

You can use values higher than 100, but probably won't see any difference. Chroma is processed with (blur+1)/2 passes.

Note: Unless blur is specifically set, it will default to 2 if type=0.

int  type = 1

Type of blur:

• 0 : radius 6 blur.
• 1 : radius 2 blur, requires around 8x more passes than type 0 for the same effect (will be just 2.5x slower), but produce better quality.

int  chroma = 1

Processing mode for chroma planes (U and V):

• 0 : fill with zeroes
• 1 : don't care, (default)
• 2 : copy
• 3 : process
• 4 : guide by luma
• 5 : same as 3, but don't process luma
• 6 : same as 4, but don't process luma

Examples

aBlur with default settings:

AviSource("Blah.avi")
aBlur(blur=3, type=1, chroma=1)
