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")

clip   =

Input clip.

int  thresh = 128

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

Range: 0 to 255

int  blur = 2

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.

Range: 0 to 100

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

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

Range: -128 to 127

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:

AviSource("Blah.avi")
aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=4)

Guide chroma channels with luma edge mask but only process chroma (luma channel will be copied from the input clip).

aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=6)

#Identical to MergeChroma(last, aWarpSharp2()) but faster and more memory efficient. 

Process chroma channels with their own independent edge mask and copy luma channel from the input clip.

aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=5)

#Identical to MergeChroma(last, aWarpSharp2(chroma=3)) but faster and more memory efficient. 

Only process the luma channel and copy chroma channels from the input clip.

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

#Identical to MergeLuma(last, aWarpSharp2()) but faster and more memory efficient.
