aWarp is designed for a more custom warp-sharpening than aWarpSharp2 allows.
[edit] Syntax and Parameters
- aWarp (clip, clip, int "depth", int "chroma")
- clip =
- Input clip.
- clip =
- int depth = 3
- Strength of the final warping. Negative values result in warping in opposite direction, i.e. will blur the image instead of sharpening.
- Range: -128 to 127
- int depth = 3
- Note: Chroma channels are internally processed with
depth/2
.
- Note: Chroma channels are internally processed with
- int chroma = 4
- Processing mode for the chroma channels (U and V):
- 0 : fill with 0x80(128), output is grayscale.
- 1 : don't care - chroma will be trashed.
- 2 : copy chroma channels from the input clip.
- 3 : process chroma; create an edge mask from each chroma channel and use those to warp each chroma channel individually.
- 4 : process chroma; use the edge mask from the luma to warp the chroma channels.
- 5 : same as 3, but don't process luma.
- 6 : same as 4, but don't process luma.
- Luma plane (Y) is always processed, except for mode 5 and 6 which simply copy the luma channel from the input clip.
- Processing mode for the chroma channels (U and V):
- int chroma = 4
[edit] Examples
The following example is identical to aWarpSharp2()
:
input = AviSource("Blah.avi") edge_mask = input.aSobel(thresh=128, chroma=1).aBlur(blur=2, type=0, chroma=1)
aWarp(input, edge_mask, depth=16, chroma=4)
The following examples are written differently but are identical to the one above.
AviSource("Blah.avi") aWarp(aSobel().aBlur(blur=2, type=0), depth=16)
input = AviSource("Blah.avi") edge_mask = input.aSobel().aBlur(blur=2, type=0)
aWarp(input, edge_mask, depth=16)
