Deblocking with QTGMC

Hello everyone,
Im trying to deblock, video or jpg with QTGMC.
I manage to remove noise and enhanced the picture. But the blocking remain. If its not possible, is there a good filter to do this.

I have a other question, not related to this. Is there a good plugins to remove the chroma noise. I was using ccd_sse2.v1.6mt.vdf for virtualdub. The function ChromaNoise=True is not really powerfull in QTGMC.

QTGMC is a deinterlacer. For deblocking try Deblock_QED.

Thank you TheSkiller. Just Deblock_QED() seems to do the job. Is it better to apply Deblock_QED() before deinterlacing , or after ?

Definitely before deinterlacing. After deinterlacing the vertical block borders are softened and therefore cannot be deblocked properly anymore. One also must not crop before Deblock_QED. It should be used right after the source filter.

But beware: Deblock_QED() alone is not compatible with interlaced videos! To use it with interlaced videos you need to wrap it like this:

Code:
par=getparity()
SeparateFields().PointResize(width,height)
Deblock_QED()
AssumeFrameBased()
SeparateFields()
Merge(SelectEven(),SelectOdd())
par ? AssumeTFF() : AssumeBFF()
Weave()
Code by Didée.
