I'm pretty sure it is DDR266

Using Sampler() seems to bring back the old PAL-Prediction Problem. I've done some short tests with a short movie and the the final size is way off wanted size . I've already tried with a sampler length of 24 and 25. The 24-length gives a higher CQ, but still too low.
I've been using ToK 0.0.5.2 with the new video-en1-file and ToK's faster prediction method.
Any idea

I see that a smaller length size is more accurate on PAL
Have you tried "Sampler length= 15, GOP 25"
If that does target a closer final size for PAL, is it consistent with different movies

Not Yet. I've just tried a Sampler length of 30 and it was smaller...

EDIT: With Sampler length=15 the CQ is a bit higher. I'll go for a complete encoding. Results in ~ 1hour (if i'm still awake )

Could it be that there's a "sweet spot" for sampler length
How about doing a sampler from say 12 to 30, in steps of 1, and see if at a point you get a "peak" optimal value

I think we really need a batch for encoding... That would simplify alot .

Yes I know It's a real pain doing this stuff manually over and over again

The Prediction with Sampler length=15 was good
Can any PAL user try this:
My results:
I'll test some other lengths of Samplers tomorrow...
Good night,

Thanks Krassi,

This might also be a solution for higher accuracy on NTSC material

-kwag

if the source is 29,97 ntsc,

TMPGEnc don't want to work if the line in video.en1 has:
Job.MPEG.Video.VideoEncodeMode = MPEGVideoEncoder_VideoEncodeMode_Progressive_32Pul ldown

only if i use:
Job.MPEG.Video.VideoEncodeMode=MPEGVideoEncoder_Vi deoEncodeMode_Interlace

what to do?
some hints please!

Hi jorel,

That line applies only to MPEG-2 at 23.976. Not to MPEG-1. If you are encoding MPEG-2 at 29.97fps, then change the line to Job.MPEG.Video.VideoEncodeMode=MPEGVideoEncoder_Vi deoEncodeMode_Interlace.

-kwag

thanks Kwag,
i did it and see my results in mpeg2,29,97,ntsc:
with ToK 0053:
Final CQ: 56,467

with ToK 0052 (with new video.en1 and "Interlace" in the line):
Final CQ: 55,958

the CQ decrease and in my case i need to encrease!
using this values i can put more 150mb in one cdr 80 minutes.
this will be too short.

seems that only i got less size,
everybody got huge files!

length of 15 with samples/minute of 4 or more is painfully slow even on fast prediction. The first pass on my 1.8ghz machine was over 20 minutes

No jorel, you're not the only one
Me too I'm getting smaller file sizes too
I just finished "K19", and it should have been ~699,875KB, but the final encoded size is 639,574KB
That's about -8.5% under
It's a sad prediction day
Now I'm completely lost
This was with "Fast" prediction, using Tenra's 100/10 prediction. The only thing I'm left to try is full prediction instead of 100/10. If I get the same predicted CQ with normal prediction, then it's over, and this just doesn't work. If I do get a higher CQ without the 100/10, then I have to do the same with K-Pax and "The Boondock Saints" to see if the problem was the 100/10 prediction. So I guess I have one more prediction shot now , unchecking "New faster Prediction".

-kwag

And here we go
After unchecking "New Faster Prediction", and using "Full" prediction, my new "K19" movie CQ is now 62.783 instead of 57.21
No wonder I was over 60MB under
Now I have to encode "K19" again , K-Pax again and "The Boondock Saints again
Until I get all these three completely different movies down to <2% I won't be happy

Here's my ToK screenshot, with the parameters set for a full prediction sampler:



-kwag

I tried this and still came in about 60MB under on the movie I've been testing 'The Firm'

But I notice you have 1st group of passes at .5% and the second group of passes unchecked.

These aren't the default settings. Why did you choose these?

Because this way you run a full prediction sampler every time, with a .5% accuracy. It takes longer, but in the end, it should prove more accurate.
What settings did you use

Hi Kwag..

Can I get a little help here, please.. ??

There's just too many confusing things going on around here, and I'm
afraid that I don't have everything that i need for a successful testing
in aiding you (if I can offer any help, using my time)

K, first let me ask ya..

* which script are you using for all these tests ??
I want to make sure I use the exact one you are using, k ?

* Then, what template in TMPG are you using.
I want to use it also (below movie test...)

* ToK.. Main/Tab.. what are the settings ??
...can you enclude some screen shots of ToK for all the Tabs settings ??


I need to get an idea of what I'm using is correct, for the most part,
when using ToK.

My Movie test:
I want to give my Movie, "Dogma" another shot, since the last time, it
bombed out w/ bad results. But, to add, in aid for you, results I would
get w/ the predict issues. Help me, to help you

See if this chef's list is correct so far..

The one posted on the Optimal Script thread. No template
Just select in ToK 528x480, MIN=300, MAX=2,500. Initial CQ=80. Audio set to 112Kbps. Look at the screenshot I posted here for the other settings. Just as described above.

-kwag

@ Kwag..

That's just it. There's no resolution settings. Also, I remember seeing
someone's post showing their results, and their resolution was set at
* 704x480 ...(this is what I want to use in my future encodes)
.
.
...and, I was hoping to continue using the same res, but when I gave a
few shots at ToK, I got 720x480, and I never set nothing for res

Another thing...
I also notice that ToK dumps a bunch of other files in my WORK folder.
Should I be deleting them fater every encode, or project or anything I'm
finished ?? Example:
* video.en1.txt
* video.avs
* video.tpr
* ToK log file

Is it ok to change anything in any of these files, that ToK will be able to
use, if I want to change thing (like you guys seem to be doing)

Thanks again.
