A blurring filter that is usually used to blur the edge mask (the output of aSobel).
[edit] Syntax and Parameters
- aBlur (clip, int "blur", int "type", int "chroma")
- clip =
- Input clip.
- clip =
- int blur = 3
- int blur = 3
- Range: 0 to 100
- 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)/2passes.
- Note: Unless blur is specifically set, it will default to 2 if
type=0.
- Note: Unless blur is specifically set, it will default to 2 if
- int type = 1
- Type of blur:
- 0 : radius 6 blur (some kind of 13x13 average).
- 1 : radius 2 blur (some kind of 5x5 average), requires around 8x more passes than
type=0for the same effect (will be 2.5x slower), but will produce better quality.
- Type of blur:
- int type = 1
- int chroma = 1
- 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 planes from the input clip.
- 3 : process chroma.
- 4 : process chroma.
- 5 : process chroma but copy the luma plane from the input clip.
- 6 : process chroma but copy the luma plane from the input clip.
- Luma plane (Y) is always processed, except for mode 5 and 6.
- Processing mode for the chroma channels (U and V):
- int chroma = 1
[edit] Examples
aBlur with default settings:
AviSource("Blah.avi") aBlur(blur=3, type=1, chroma=1)
