Description

The same as aWarp(aSobel().aBlur()) but a bit faster.

Syntax and Parameters

aWarpSharp2 (clip, int "thresh", int "blur", int "type", int "depth", int "chroma")

int  thresh = 128

Range: 0 to 255

Saturation limit for edge detection. Reduce for less aggressive sharpening.

int  blur = 2

Range: 0 to 100

Number of blur passes over edge mask.

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

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 3 if type=1.

int  type = 0

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 2.5x slower), but will produce better quality.

int  depth = 16

Range: -128 to 127

Strength of the final warping. Negative values result in warping in opposite direction.

int  chroma = 4

Processing mode for chroma planes (U and V):

• 0 : fill with zeroes
• 1 : don't care
• 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

aWarpSharp2 with default values:

aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=4)
