ok.

1 DVD5-R got 4482 MB, now we do subtract the muxing overheat of 180mb = 4300 MB!

That means you're capable to put 4300 MBs to that Media.
Give it maybe another safe margin by 100MBs for complex still menues=4200 MBs.

Now as you want to burn 3 Movies on that DVD5-R you devide it by 3:

=1400 MBs for each movie if you do a prediction on each movie!

Next is you do encode your audio to 48khz AC3 or mp2. Maybe the movie of that one movie results in 100 MB. This would mean:
1400-100= 1333MB

So these 1300 MBs should be the wanted endsize for the prediction on that movie.


But you should do predict all three movies as ONE!
Generating an avs script where these Movies will be added to one frameserved stream.

take the size of all ready encoded audiotracks and do subtract that size from 4200. Now i.e. 3900 MBs would be the result. This value should be the needed Finalsize for prediction. Do a prediction on that avs WITHOUT encode afterwards option.

If the prediction would result in Q 25, therefore you do encode all these 3 movies separately at Q 25 and all that data should fit to that one DVD5-R.

I don't have 3 movies yet lol jus the 1 (DVD ON HD)
my mp2 audio is 110 mb so end size for Johnnys qcce is 1323 mb BUT ?
Does Johhny QCCE ask for target size without audio or with ?
Im confused, I assumed it wanted a targetsize without the audio.
Have u ever used johhnys toy ? if u have isnt it off alwayz?

incredible 01-25-2004 12:16 PM

Without audio, as Qcce can not assume what bitrate the audio gots

The Untouchable 01-25-2004 12:20 PM

All I'm sayin is johnnys toy is really messed up I set targetsize for 1380 mb lastnight & the size that cameout was 1.47 gb WHY ?
WHAT DO I HAVE TO LOWER IN QCCE to get a lower filesize
(besides the target size what else can I lower or raise or whatever) :cry:

rds_correia 01-25-2004 01:39 PM

Hey touchy,
You don't need to get so mad :evil:
Just remember that jonny gave us his proggy for testing a few days ago.
We all want to predict faster and better but we need to be patient as this is a trial and error process.
If you could do your math you could try Incredible's Slicer :cut: routine.
In fact I think that both Inc & Jonny are working to integrate Slicer into qcce.
So give it some more testing while you/we wait for it to be 100%.
As always post your results so that jonny can improve.
Cheers

The problem is: If someone not get his things DIRECTLY to work, its called that these things are messed up. But there's not only the program, there's also the user (no offense but in 80% of these cases, mad users should think about it, no matter what appl. or what workout).

Do you think I was that good at mathematics in shool :lol: Never!
Its just a thing of patience, to get INTO things and to read things carefully like that ping-pong-Thread where everything is explained.

Jonny did a good job! Until now I did some DVD5-Rs using Qcce and they did fit very well, exept one where ca. 50 MBs where over the final size, so what? Using Rejig or ShrinkDVD did fix that one also fast and seen the Job as a whole totally its much faster compared to TmpgEnc.

So I agree with rds_correia.

Hey Incredible ...
I wont say anythin cuz u bin goin outta your way ta help me lately :P
But last night I set target size to 1000 mb (in QCCE) & THIS MORNIN THE FINAL SIZE WAS 1.47 GB :cry:
Thats the shit I'm talkin about !!

The Untouchable 01-25-2004 06:15 PM

So u tellin me that I should take the overly large sized files & when I get 3 movies to jus basicly use "Dvd shrink" ta shrink the size ?
But

(1) wont that reduce quality
(I found Shrink DVD has the worst quality of all the shrinkers)
(Only good thing about it is the authoring bit) :wink:

(2) Wont "Dvd Shrink rewrite the files but without the K-VCD Notch Matrix?

I hope it don't rewrite files with the normal mpg matrix ????

Dialhot 01-25-2004 07:03 PM

Untouchable, did you tried at least ONCE the (trust me) very simple method described by VMESQUTA and that I resumed to you in my previous post in this thread ?

It needs only 3 or 4 samples and gives perfect results ! Why don't you tried that if you can't manage to use an external tool ?

Well I will keep helping you as I did before but I do not just eat everything someone says, ya know? :P

Depends, if you won't go under 95% you won't recognise. But that was in my case of 50 MBs over a wanted filesize of a DVD5-R media size!

The "worst" statement I can't duplicate, but thats not the subject now ... well shrink does it JOB very well and in case of not going under 90% in already very compressed streams its a nice choice also cause of acurate percentage stream compressing. And in Case of very high bitrate original DVD sources you even can go lower than 90%.

Thats not a new matrix alocation thing although its a DCT based transforming job but one of the advantages is that the vectors won't have to be recalculated for example and that also makes it very faster.

So finally if the transforming on 1300 MB KDVD movies won't go below the 95% marker, you won't recognise it.

The Untouchable 01-25-2004 07:18 PM

Hi phil ... yes I gave it a shot, but am alil confused cuz i got some weird number in the calculator
I loaded the Avs file in Virtualdubmod & wrote down the # of frames
(217947) (without audio, Dunno how ta open mp2 audio with Vdub)
Divided that by 121 minutes then divided that # by 18 GOP (ntsc) then
Divided that # by 1200 mb & I got a messed up # ... (0.0833895)

I have no idea if i did it write or wrong or if i need ta open the mp2 audio file in vdub to get the correct # of frames or even what ta do with that # the calculator gave me

Frame is an other word for 'picture' or 'image' and so is related only to video.

Your error is there. You don't have to divide the number you obtained (what you called "that #") by the size (1200 MB). You have to divide 1200 by "that #" !
In other words, the number you are looking for is the invert of the one you obtained. The invert of 0.0833895 is 1/0.0833895 = 11.99.
That is the size in MB that your sample must do after encoding.

The Untouchable 01-25-2004 07:40 PM

Still alil confused my friend, do I need ta open the audio (mp2 file) in Vdub to get the correct # of frames of is the avs script enought by it'self

Dialhot 01-25-2004 07:43 PM

Again, no ! Frames are not related to audio.
The number of frame is the number of images in your video !

The Untouchable 01-25-2004 09:31 PM

OK so now I understand all that u said, But I tryed readin the rest of vmesqita's guide ... It gave me a link to a kwag samplerscript which was made for the avisynth 2.08 s now I'm lost again.

My calculated samplesize came out to (# 11.08 )
But what am I supposed to do with this sample #?
I'm not too sure what I'm Supposed to do with this sample #
Am I supposed ta load the script into cce & mess wit the Q till i get a sample sized 11.08mb or do i have to change cce settings like
min bitrate from 300 to 64 & max bitrate from 5000 to 3000 & then mess with the Q ?

Man somethin is wrong I have to raise Q (IN CCE) to like 120 just to get a sample 16 mb big & its still too big :cry:
HEEEEELP :cry:

No, just vary the QFactor only!

Maybe then it doesn't fit with good quality... It can happen. But looks like you're predicting for just 1 movie, right? Try doing for the three at the same time.

All you have to do is to take the script that you plan to use for the encoding and add the line :
Code:

sampler(length=18)
(18 is the length of the GOP, change it if you use a GOP that is different).

Then you launch the process on this script; At the end the size of the video must be the one you are looking for (11.08 ). If not, you change the Q only, as told by VMesquita.

When you have find the correct CQ, you just have to remove the line "sampler", and you can do your final encoding.

The Untouchable 01-26-2004 08:59 AM

Thing is vmesquita ... I only have a 40 gig harddrive with about 10 gbs to spare, I dont have enough room on it ta hold 3 movies b4 converting to K-DVD
