I think this is mainly related to cartoon sources etc...
I had this same problem in Divx 3 sbc, and the only way I could get rid of it is by setting the drf and keyframe mins to 3, anything lowr, and I'd get shit frames. This ONLY happens on this particular source for some odd reason.

My settings are as followed..

Motion Serch : 6
Type H.236
FourCC Used : Xvid
Max I-Frame Int: 300
Luma Masking is enabled

quant are default 1-31 I and P
Two Pass deault
alt cc

Medium
High 200%
low 75% str 50% etc...

So i've tried several differnt settings etc... but it seems , when I set the min quant to 3, the pixel stuff goes away , My only problem with that is, the video looks NASTY. Looking at the debug window on the first pass, most of the frames are set to a qunat of 2 or 3..

I hope I'm explaning myself correctly, if you want a picture of whats happening let me know. Any Ideas I could do, in the settings, or some filter I could try? I've tried both Temproal smoother at str 2 and 3, no help there..

loadplugin("mpeg2dec.dll")
loadplugin("decomb.dll")

mpeg2source("a92.d2v")

Telecide(guide=1,gthresh=25,chroma=true,threshold=10)
#Telecide()
Decimate(cycle=5)
crop(4,0,712,480)

BicubicResize(512,386,0,0.75)
TemporalSmoother(3)
#trim( 0 , 157)

thanks

Disable luma masking, on hard sources and with that bitrate you seem to have it does more harm than good. Maybe giving MPEG or modulated quantisation type a shoot can help it somewhat either.

tried that same thing. :( I'll try modulated next. See if that helps, thanks for the tip

Are you really resizing to 512x386 as it says above? In that case, change that to 512x384.. :) 386 is only an even power of 2, and that could cause some probs.

Also, try doing the TempSmoother before the resize, that always increases quality. (but it probably has nothing to do with your problem, just a tip)
