Introduction
- Designed to provide 8x8 deblocking sensitive to the amount of blocking in the source, compared to other deblockers which apply a uniform deblocking across every frame.
Required Filters
- DeBlock
- MaskTools2 2.0a48+
- DCTFilter
Parameters
DeBlock_QED(clip clp, int quant1, int quant2, int aOff1, int bOff1, int aOff2, int bOff2, int uv)
- quant1 int = 24
- Strength of block edge deblocking.
- quant2 int = 26
- Strength of block internal deblocking.
- aOff1 int = 1
- Halfway "sensitivity" and halfway a strength modifier for borders.
- aOff2 int = 1
- Halfway "sensitivity" and halfway a strength modifier for block interiors.
- bOff1 int = 2
- "Sensitivity to detect blocking" for borders.
- bOff2 int = 2
- "Sensitivity to detect blocking" for block interiors.
- aOff and bOff controls block detection and removal strength, for quant1 and quant2 respectively. See DeBlock for more information.
- uv int = 3
- Deblock chroma:
- 2 : Copy chroma from source.
- 3 : Process chroma.
- 1/-1 : Process chroma with normal/strong Deblock().
- Deblock chroma:
Examples
AviSource("Blah.avi") Deblock_QED(25, uv=false)
Changelog
Changes 2008-08-18: (Didée)
- Replaced the ugly stackXXX cascade with mt_LutSpa() (requires MaskTools v2.0a35)
- Changed Quant and Offset defaults to 24,28,2,4,4,8
Changes 2010-05-25: (Bi11)
- Explicitly specified parameters of mt_LutSpa()
(required due to position of new 'biased' parameter, starting from MaskTools 2.0a43)
- Non mod 16 input is now padded with borders internally
Changes 2010-08-18: (Bi11)
- Replaced AddBorders with PointResize
- Changed Quant and Offset defaults to 18,19,3,4,1,1 to reduce blurring
Changes 2010-10-16: (Bi11)
- Replaced 'relative' with the new 'mode' parameter in mt_LutSpa(), starting from MaskTools 2.0a45
- Changed Quant and Offset defaults to 24,26,1,1,2,2 to increase effectiveness, but still within sensible limits.
(see for details: http://forum.doom9.org/showthread.php?p=810932#post810932)
Changes 2011-11-29: (06_taro)
- Replaced (chroma=uv>2?"process":"ignore") by (chroma=uv>2?"process":"copy") to avoid garbage clip when uv=2.
The formal parameter is not used by MaskTools2 any more, if ever used.
Foxyshadis once mentioned chroma="ignore" but I had never found a document containing it.
