Description
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.
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
- Width and height need to be mod8.
Required Plugins
Latest versions of the following filters are recommended unless stated otherwise.
Syntax and Parameters
- DeBlock_QED (clip clp, int "quant1", int "quant2", int "aOff1", int "bOff1", int "aOff2", int "bOff2", int "uv")
- clip clp =
- Input clip.
- clip clp =
- int quant1 = 24
- Strength of block edge deblocking.
- int quant1 = 24
- int quant2 = 26
- Strength of block internal deblocking.
- int quant2 = 26
- int aOff1 = 1
- Halfway "sensitivity" and halfway a strength modifier for borders.
- int aOff2 = 1
- Halfway "sensitivity" and halfway a strength modifier for block interiors.
- int aOff1 = 1
- int bOff1 = 2
- "Sensitivity to detect blocking" for borders.
- int bOff2 = 2
- "Sensitivity to detect blocking" for block interiors.
- int bOff1 = 2
- aOff and bOff controls block detection and removal strength, for quant1 and quant2 respectively. See DeBlock for more information.
- int uv = 3
- Deblock chroma:
- 2 : Copy chroma from source.
- 3 : Process chroma.
- 1/-1 : Process chroma with normal/strong Deblock().
- Deblock chroma:
- int uv = 3
Examples
Deblock_QED with default settings:
AviSource("Blah.avi") Deblock_QED(quant1=24, quant=26, aOff1=1, aOff2=1, bOff1=2, bOff2=2, uv=3)
Changelog
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.
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. (Details: http://forum.doom9.org/showthread.php?p=810932#post810932)
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 2010-05-25: (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 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 2005-10-28: (Didée) - Initial release
