Description

It performs deblocking on the picture, using the deblocking filter of H264. It's useful to deblock the result of MVCompensate of MVTools plugin, etc.


Requirements


Syntax and Parameters

Deblock (clip, int "quant", int "aOffset", int "bOffset", string "planes", int "opt")


clip   =
Input clip, width and height must be mod 8.
int  quant = 25
The higher the quant, the stronger the deblocking. Range is from 0 to 60.
int  aOffset = 0
Quant modifier to the blocking detector threshold. Setting it higher means than more edges will deblocked.
int  bOffset = 0
Another quant modifier, for block detecting and for deblocking's strength. There again, the higher, the stronger.
string  planes = "yuv"
Specifies which planes to process between y, u and v.
int  opt = 0
Sets which cpu optimizations to use.
  • 0 : Auto-detect.
  • 1 : Use C++ code.
  • 2 : Use SSE4.2 code.
  • 3 : Use AVX2 code.
Only 8-16bit is optimized, not float.


  • If quant + aOffset is less than 16, the filter does nothing at all. The same goes for quant + bOffset.


Examples

Deblock with default settings: 

MPEG2Source("Blocky.dv2")
Deblock(quant=25, aOffset=0, bOffset=0, planes="yuv")


To deblock the motion compensation (MVTools plugin): 

vectors = source.MVAnalyse(isb = false, lambda = 1000)
compensation = source.MVCompensate(vectors, mode = 0)
compensation.Deblock()
