It should work the same with AVIs. Same principles apply.

It seems not to work with PAL system.
I try prediction with "The Matrix" for one CD at 704x576 (I have recently encoded it at that resolution with CQ 56):
- average bitrate 755 (cutting end credits)
- set min=430 / max 2000 (using ToK 0.0.5.2, Avisynth 2.5x and last script)
- factor for prediction 1,02 (overburning)
- new faster prediction (Tenra) with precision 0,5%
- lenght of sample 24 / nr. of sample 1
- audio 128 and GOP 25

Ended prediction with factor of apprx. 34...

Any idea?

I rest with my method, working for me (PAL): standard setting in ToK (v0.0.5.2), but with nr. of sample set to "2", GOP 25 and lenght of sample 24 (works also well with fast prediction).

Yes. Do a manual prediction with "Sampler()"

With manual prediction:
frames 186314
time 02:04:13
PAL 25 frames
186314/124/25 = 60,10
800 MB - 115 MB (audio) = 685 MB (for video)
685/60,10 = 11,39 MB (size for sample)

found CQ 57,3 (at 11,4 MB) :P

Well, but now the most important thing: encoding!

Thanks kwag, as soon as possible I post my result...

EDIT:
Well, encoding finished, final file size is 686 MB!

Hello peoples

Does anyone have any good .AVS samples of the "sampler" for the
manual prediction method ??

All I have (after a careful search) is what I got (below) but I know there
are some missing pieces before and after hte Sampler() ...
Note, I'm not using MStacker (nor do I have it installed) I'm simply
trying to understand the "prediction" process

Thank you all,
-vhelp

The only thing I do, is to add as last line to my AVS script the command "Sampler(lenght=24).
Then I launch TMPGEnc to create sample video, after I found exact size I want, comment last line (sampler command) with "#", and encode the full movie.
I remember you the great Kwag guide for understand manual prediction
here: http://www.kvcd.net/forum/viewtopic.php?t=2102

I hope this can help you.

hi break..

Thanks for your response. Actaully, I have read that link - many times, and
am still a bit dazed at it. But, in any case, I don't think it is used any longer,
per Kwag's recommend (elsewheres) where he (in so many words)
said, this is the new prefered method or something like that. I can't remember.

But, I read that that link has some issues w/ which page has the actual
how-to preduct process.

Sooner or later, I'm bound to get it. At the moment, I'm resarching one
too many things

Thanks again pal,
