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.

• DeBlock for AviSynth 2.6 - faster and supports all planar colorspaces. Download | Discussion

Syntax and Parameters

Deblock (clip, int "quant", int "aOffset", int "bOffset")

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.

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

Examples

To deblock the motion compensation (MVTools plugin):

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