Nah , there's not Quote:
i dont think so but it would be great to be closer to the target w fast prediction.

Let's see: A CD-R is approxmately $0.25 each. About a quarter. So 30 MB would be 3.75% of 800. Now 3.75% of a quarter is 0.0093 cents. Do we really want to find the correct CQ to fill the disk with no visual quality gained for less than one cent I don't

I think we could just up our prediction factor by a smidge if doing fast prediction, no? Like say 1.01 or 1.02

I keep coming up 5 or 6% short even though as you guys said the CQ values are close. I'm going to keep trying, but I think 48 frame samples at 2 per minute will really slow down prediction time, but we'll see. I haven't tried yet.

We could, but what guarantee do we have that when ToK is using fast prediction, the 0.5% sample is not over instead of under the wanted size
So you could end with -30MB or with +30MB, depending if the sampler was -0.5% or +0.5% from wanted file size. I rather do a full prediction with a factor of 1.0 just to be sure. I'm currently starting to encode a complete different movie I haven't tried with the latest settings. It's "Under Siege 2". We'll see tomorrow how it comes out

@ Kwag
I'm encoding "Foreigner" Pal version and have 2 problems
1 . Encoding with last script is taking 8hr 20 min and with script before
last changes 3hr 35 min
CQ = 61 in both cases and res=704x576
with last script quality is slightly better (less mosquitos around subs )
but encoding time ~3 times slower ????
What could be the problem ???
2 . Prediction with Tok 0.0.5.2 or 0.0.5.3 with fast mode always
results files 40-50mb smaller then whanted .
I tryed to play with param's but cant get constant results with different movies .

Hi bman,
For me ToK never worked correctly, so I tried another procedure which gave me correct results for PAL, but it is not wide tested. I will give you a link to the post
http://www.kvcd.net/forum/viewtopic....=asc&start=128
Try it, if you want.

Hi bman,
have you tried ToK 0.0.5.2 with a Sampler length of 24 or 48 My predictions are within 1% since i use these settings (doesn't matter if i use faster prediction or the older one). You could also try to go for a higher value at samples/minute.

Thank's Kwag !!!
I'm encoding with 704x576 and it takes ~8.5hr to encode .
U have encoded 528x480 and it took ~5.25hr to encode .
So 704x576 / 528x480 *5.25 = 8.4 hr
It's about the time that took me to encode "The Foreigner" with CQ 61 .
I'm happy that my system is tuned up and quality is great too but 8.5hr
encoding is too much time for me , on job that could be done in 3.5hr with previous script and hardly noticable difference
Correct me if I'm wrong

There is a HUGE difference in quality from the old 2.0x script (non-adaptive) to the new Motion Adaptive script

Absolutely right !!!
We just missunderstand one each other
I'm talking about MA script before the last changes u made (with conditionalfilter and without )
With NEWEST script If u are encoding 528x480 it could be a big difference but not with 704x576 .
Even on 34" TV it's hard to see difference cos TV is smoothing most of mosquitos .
That's just my opinion , That's what I see

Sykes,download temporalcleaner here:
http://www.avisynth.org/~warpenterprises/
i think that you don't have this filter for use in the new script!
editing:
no need the filter no more,
temporalcleaner was changed for temporalSoften.
copy the script again!

You bet you are
Change this line:
ScriptClip("nf = round(YDifferenceToNext()+1)"+chr(13)+ "nf > 2 ? \
Dialhot's line read:
ScriptClip("nf = round(YDifferenceToNext())"+chr(13)+ "nf > 2 ? \
and the value would go to zero, which causes "division by zero".
With the above fix, now it never goes below 1

Looking at the changes by Dialhot, I overlooked something
The values are integer now, but that throws OFF completely the boundary between the switching of blurring and temporal filter. Before, there was a floating point precision. And now it's sharp values that jump from 1 to 2, and that's NO good
I'm revising the script again
Edit:
Ignore this post. I need sleep. The script is correct
