Abstract

category: Misc Plugins
requirements: YV12, YUY2 Colorspace
license: GPL

It does a deblocking of the picture, using the deblocking filter of h264. It's useful to deblock the result of MVCompensate of MVTools plugin, etc.

Syntax and parameters

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

quant : the higher the quant, the stronger the deblocking. It can range from 0 to 60.

aOffset : quant modifier to the blocking detector threshold. Setting it higher means than more edges will deblocked.

bOffset : another quant modifier, for block detecting and for deblocking's strength. There again, the higher, the stronger.

Defaults are quant = 25, aOffset = bOffset = 0. If quant + aOffset is inferior to 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()
