Description

aWarp is designed for a more custom warp-sharpening than aWarpSharp2 allows.

Syntax and Parameters

aWarp (clip, clip, int "depth", int "chroma")

clip   =

Input clip.

clip   =

Edge mask clip; usually the input clip processed by aSobel and followed by aBlur.

If you want more stable results it's good idea to do anti-aliasing and temporal filtering on the edge mask before passing it to the warping stage.

int  depth = 3

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

aWarp with all default settings is identical to aWarpSharp2():

input     = AviSource("Blah.avi")
edge_mask = input.aSobel(thresh=128, chroma=1).aBlur(blur=3, type=1, chroma=1)

aWarp(input, edge_mask, depth=3, chroma=4)

The following examples are written differently but are identical to the one above.

AviSource("Blah.avi")
aWarp(aSobel().aBlur())

input     = AviSource("Blah.avi")
edge_mask = input.aSobel().aBlur()

aWarp(input, edge_mask)
