[edit] Description
Deblocking function based on blindPP and high/lowpass separating. This is of most use on HEAVILY compressed source material.
[edit] Requirements
- AviSynth 2.5.8 or greater
- Progressive input only
- Supported color formats: YUY2, YV12
[edit] Required Plugins
Latest version of the following plugins are recommended unless stated otherwise.
- DGDecode - part of the DGMPGDec package
[edit] Syntax and Parameters
- funkydeblock (clip c, int "quant", int "th", int "radius", bool "deblock", bool "depump")
- clip =
- Input clip.
- clip =
- int quant = 4
- The quant parameter usually fed into blindPP. The default is 4 which is actually very conservative due to the fact it's only used on the highpassed clip, so even quant=31 gives a good picture.
- int quant = 4
- int th = 3
- TemporalSoften threshold. Only active when depumping is on. Default 3. This parameter controls how sensitive to pumping the filter is. keep it low, unless you're seeing large jumps at I frames. Increase only as much as you have to, or dim moving objects will start vanishing.
- int th = 3
- int radius = 4
- The number of frames before and after currentframe used in TemporalSoften. Default 4. This is intended to smear GOP changes, so pumping doesn't show as much.
- int radius = 4
- bool deblock = true
- Turn deblocking on/off (only depumping is used). Default true.
- bool deblock = true
- bool depump = true
- Turn depumping on/off (only deblocking is used). Default true.
- bool depump = true
[edit] Examples
funkydeblock with default settings:
MPEG2Source("Blocky.dv2")
funkydeblock (quant=4, th=3, radius=4, deblock=true, depump=true)
[edit] Script
function gauss (clip c, int "radius") {
radius=default(radius,1)
radius=radius*4
c.bilinearresize(4*(c.width/radius),4*(c.height/radius)).bicubicresize(c.width,c.height,1,0)
}
function funkydeblock (clip c, int "quant", int "th", int "radius", bool "deblock", bool "depump"){
quant=default(quant,4)
th=default(th,3)
radius=default(radius,4)
deblock=default(deblock,true)
depump=default(depump,true)
blurd = c.gauss(4)
highpass=subtract(blurd,c)
deblocked=(deblock==true) ? highpass.blindpp(quant=floor(quant),cpu=4) : highpass
nopump=subtract(blurd,deblocked)
pump=subtract(blurd.temporalsoften(radius,th,th,2*th,2),deblocked)
(depump==true) ? pump : nopump
}
