Just had the following idea to get prediction working:

How about doing a prediction with the same source (e.g. a wide-spreaded movie like "The Matrix") and the same settings (resolution, avs-script, TMPGEnc project settings) All users who want to be a part of this could then post their results.
Then we could easily compare all differences between PAL and NTSC, resolution and other things/issues.
After that we could consider other sources etc.
Maybe Kwag could suggest the first settings for the beginning.

I hope everybody understood my idea

Hello krassi:

Great idea. I believe that we may be doing something like this shortly. Similar ideas have been posted in this thread:

CQMatic 1.1.0.2 took 69 Minutes of Time and gave a CQ of 50,49, which seems to be accurate, because last night I encoded the whole with CQ 52,77 and it was over the target size.. That Program is damn funny, on some Movies it is acting totally crazy and now it puts out a presumeably accurate CQ. Here's the whole Log:

Thanks for the input, Bchteam. I'll start an encoding with the same settings right now. Maybe a NTSC user can make a test also

@Bchteam:
Are you using the latest MA-script If not, can you post your script please
Are you using DVD2AVI 1.77.3

I'm using DVD2AVI 1.76
I'm using the latest script from Kwag:


Code:
## Main section and static filters ### 
# 
Mpeg2Source("H:\Matrix\MatrixProject.d2v") 
#
undot() 
Limiter() 
asharp(1, 4) 
BicubicResize(528, 480, 0, 0.6, 0, 0, 720, 576)
STMedianFilter(8, 32, 0, 0 ) 
MergeChroma(blur(MaxTreshold)) 
MergeLuma(blur(0.1)) 
# 
# 

## Linear Motion Adaptive Filtering ## 
# 
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to 
# very static scenes, and apply variable blur on moving scenes. 
# We also assign a variable - and this is why a line break is inserted: 

SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2 
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= 2 ? \ 
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \ 
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) ,1, 1) ") 

# 
# 
# 

LetterBox(16, 16, 24, 24)
Limiter() 

# 
# 
## Functions ### 

function fmin(int f1, int f2) { 
  return (f1<f2) ? f1 : f2 
}

@Bchteam:
Well, i have the first difference:
I've just done my d2v-file with DVD2AVi 1.76 and my movie length (Matrix of course) has a length of 130 mins and 46 seconds
Your target was for a 80 min-CD, right

EDIT: Can you try to make a prediction without filters My machine is sooo slow (one prediction cycle > 45 mins )
I'll do one with the following avs:
Code:
Mpeg2Source("T:\Matrix_176.d2v")
BicubicResize(528, 480, 0, 0.6, 0, 0, 720, 576)
LetterBox(16, 16, 24, 24)

Hello Krassi,

I will make the tests within the next Hour.

And of course, my target is 1 Disc (80 Min, 700MB)

@Krassi,

If your source is PAL, please "uncheck" the "Interlace" option in CQM. I have to make a note of that, that it's only for 29.97fps interlaced sources.
It's being set automatically from your TMPEG project.

I'll look for a PAL source somewhere, so I can make a test.

Why Interlaced Source Correction
The option is "Unchecked" before you click on "Execute"

Results of the final encode with the above settings:
Wanted VS: 704 512 KB
Encoded VS: 613 414 KB

Now i'm going to play around with the interlaced button

Any other users Come on, nobody got Matrix

Confirmed, it has been imported from my project file Enabling/Disabling didn't change anything on prediction.
I'll try now with the progressive setting in TMPGEnc.

excuse me....
i don't have "the matrix" to encode but all my tests
give me 15% less size from the desired target!

are proportional like your results Krassi!

Hi Jorel
i'm just testing with TMPGEnc-project-file set to progressive instead of interlaced. I thought TMPGEnc would set it right when importing the video file but it seems to be wrong.
Prediction with progressive setting seems to do a better job. I'll post the results in about 7 hours, its time to sleep right now here in Germany...
Maybe you could make a test with progressive too
Thats my current log:
