I'm pretty sure it is DDR266 :cry:

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 :D )

Could it be that there's a "sweet spot" for sampler length :idea:
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 :?:

-kwag

I think we really need a batch for encoding... :roll: That would simplify alot 8) .

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

:ole:
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,

Krassi

Thanks Krassi,

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

:!:
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 8O

No jorel, you're not the only one :!:
Me too :!: I'm getting smaller file sizes too :cry: :cry:
I just finished "K19", and it should have been ~699,875KB, but the final encoded size is 639,574KB :cry: :cry: :cry:
That's about -8.5% under :cry:
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 :x, K-Pax again :x and "The Boondock Saints :x again :!:
Until I get all these three completely different movies down to <2% I won't be happy :twisted:

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..

Thank you for your time.

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 8O

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.
