I said that, because that's what the developer of Blockbuster (SansGrip) said
He even proved it in the "CQ vs. CQ_VBR" thread.
At 352x240, in CQ_VBR, it works very well. Above that resolution and using CQ, no matter how strong you apply Blockbuster noise, it barely diminishes the DCT blocks. He provided screenshots in the thread mentioned above.

The problem here is different : we use blockbuster for eliminate already existing blocks that are in divx. Not for avoiding new ones.
For this purpose (I can't provide screenshots, sorry ), blockbuster works either in CQ than CQ_VBR mode.
Now, I agree with you that CQ_VBR is better only at VCD res, and CQ for res above.

Ok, I see. Then you're "spraying" the DCT blocks with noise

Does this script look okej
Code:
LoadPlugin("C:\Filters\MPEG2Dec3.dll")
LoadPlugin("C:\Filters\atc.dll")
LoadPlugin("C:\Filters\Blockbuster.dll")
LoadPlugin("C:\Filters\VSFilter.dll")
LoadPlugin("C:\Filters\dctfilter.dll")
AVISource("C:\movie.avi",false)
Blockbuster(method="noise",detail_min=1,detail_max=8,variance=0.3,seed=5823)
ATC(1,2,4,0.5,false)
TemporalSoften(2,7,7,3,2)
Blockbuster(method="noise",detail_min=1,detail_max=10,variance=0.5,seed=5823)
DCTFilter(1,1,1,1,1,1,0.5,0)
gripCrop(540, 480, overscan=2,source_anamorphic=false,dest_anamorphic=false)
GripSize(resizer="lanczosresize")
GripBorders()
TextSub("C:\movie.srt")
converttoyuy2()
Is there something who should be changed

Hi,nice results with the divx,xvid script but what is everyone using for prediction.
I did a manual prediciton with the last movie and it was pretty good(tiny bit too big)
So whats everyone using
Thanx

Try the latest CQMatic. It should do a descent job on AVI prediction too.
Previous versions didn't work very well, because of the sampling that was used. That was changed in version 1.2.00

CQMatic is doing a thumbs up job on avi encodes.

I have tried this script and the results are promising. But as far as I know we have to use a different setup in TMPGEnc due to the fact that we do not have a MA script. In my opinion it makes sense to define which options should be used with this script.
- Min bitrate: 300 and Max bitrate: 2500 or should we use 0,57 avg bitrate and 2000
- Motion search precision: High quality or should we use motion estimate search
Maybe there are more options which are interesting.
Is it possible to have a sticky post with a optimal Divx script?
Thanks!

Just to add to the last post, I'm getting funky predictions with cqmatic and tok. what are you guys using for min/max bitrate? Detect scene change? And you use calcumatic to get avg bitrate? Just wondering how you're getting accurate avi predictions.
Oh and I second the motion for a divx optimal script sticky. Perhaps dialhot could moderate it?

HI J-Wo
I have only done 1 movie so far but this is what i got with the kvcd 352X240 template
DEtect scene change not selected and calcumatic to get avg bit rate
Manual prediction min 300 max 1800 -CQ 80.75(file tiny bit too big)just cut out 1 min of the ending credits
TOK CQ80.693 min 300 max 1800
CQ matic min300 max 1800 -CQ 81.8 50 50]mb too big
CQ matic avg *57 min and 1800 max CQ 80.70(didn't encode but would have been the closet)
Obviously its too early to be sure but this is from my first try.

thanks bigggt. Just wondering though, do you think visual quality will be affected much by having such a low max bitrate? I thought kwag said we could lower it to 2000 because we were using the MA script, but now we're not anymore...

I think with the higher templates you would still use 2500 max(correct me if i'm wrong) but i used 1800 because it was the 352X240 template which the max should be 1800
