I just finished an encode with shocking quality results with one irritating exception - gnarly blocks will appear on certain solid surfaces and darkly lit scenes!! This is nothing new, of course, but I was looking for recommendations from you guys on the best way to ameliorate that problem...

--------------------------------------------------------------------------------
current script
--------------------------------------------------------------------------------
AviSource("something",false)
ConverttoYUY2
LegalClip()
GripCrop(528, 480, overscan=2, source_anamorphic=false)
GripSize(resizer="BicubicResize")
SpaceDust()
sharpen(0.7)
FluxSmooth(temporal_threshold=7, spatial_threshold=7)
TemporalCleaner(ythresh=5, cthresh=10)
BlockBuster(method="noise", detail_min=1, detail_max=7, variance=0.3, seed=1)
GripBorders()
LegalClip()
---------------------------------------------------------------------------------
I was thinking maybe dropping the CQ a few points (from 85) to make room for a higher minimum bitrate. Just an idea.

IME this script:

Code:
PixieDust()
sharpen(0.7)
mergechroma(blur(1.58))
mergeluma(blur(0.7))
...does a pretty good job at eliminating moving blocks in dark/flat surfaces. Havent tried the latest script but it would probably do a good job too.
