Hi Kwag
Heres a few ive done and been checking the outcome of the file sizes between CQ70 and then upping to 74 all are within 100MB to 120MB more using CQ74 except Wizard of OZ, Re-encoded both twice because i thought i messed a setting up but i didn't they were all set correctly. Why you reckon there is such a big difference between CQ70 and CQ74 on that movie.
All done using :
SmartRipper 2.41
DvD2AVI 1.76
TMPGEnc Plus 2.52.34.139
----------------------------------
Snow White (PAL)
Length 80m:08s / animation
352x288
New GOP settings (1,12,3,1,0)
669 MB (702,480,128 bytes) CQ70
771 MB (808,547,724 bytes) CQ74
----------------------------------
The Fox and the Hound (PAL)
Length 79m:18s / animation
352x288
New GOP settings (1,12,3,1,0)
571 MB (599,426,996 bytes) CQ70
683 MB (716,262,138 bytes) CQ74
---------------------------------
The 6th Day (PAL)
Length 118m:32s / movie
352x288
New GOP settings (1,12,3,1,0)
626 MB (656,569,508 bytes) CQ70
744 MB (780,232,816 bytes) CQ74
--------------------------------
Final Fantasy - Spirit Within (PAL)
Length 101m:39s / animation
352x288
New GOP settings (1,12,3,1,0)
541 MB (567,365,092 bytes) CQ70
652 MB (683,752,404 bytes) CQ74
--------------------------------
Wizard of Oz (PAL)
Length 97m:39s / movie
352x288
New GOP settings (1,12,3,1,0)
740 MB (776,620,376 bytes) CQ70
960 MB (1,007,319,208 bytes) CQ74

Hi Pnumonic:
Perfect!. So I guess the numbers of +-4 increments that I mentioned before are very close to +-100MB.
This is very good news, because we can use these guideline for future encodings, if we need to do a second encode ( Manual 2-time ( or second time ) CQ )
About the "Wizard of Oz" who knows what happened there! Maybe TMPEG doesn't like old movies
Thanks for your time and information!,

Goto the setting tab.
Video > Rate control Mode > settings Tab.
Either move the slider rail or input your own number for quality.
The higher the number the bigger the file size, i normally go for 74 now.
most anime/CGI you can get over 2hrs but movies can vary.

Ok i have to disagree with you cause i've made some movies at 78 CQ, and they had an increase of about 130mb or less than 100, this movies are the sixth sense and billy elliot, when i increased to 74 there were only a 50mb extra in my movies, BUT when i put the CQ at 80 and above there was a huge increase in the size about 250mb in comparison with the file at CQ of 78 for example:
Sixth Sense
CQ 70 = 592MB
CQ 74 = 625MB
CQ 78 = 672MB
CQ 80 = 890MB
CQ 82 = 903MB
Billy Elliot
CQ 70 = 608MB
CQ 78 = 740MB
So in my case the increase was proportional and not lineal, cause is not always the same increase each four or even each one CQ value. This is maybe because this movies are too dark and there's no place from where to take more detail so the movie only increases a little bit until you put it to 80 or above.
This was my experience.
Saludos!
DaDe.

Hi DaDe:
Good numbers for reference. For the numbers I see, I assume your resolution is 352x240(28 . Am I correct?.
I am running a test on "The Matrix" right now starting at CQ=74 at 352x240 to find out what the output size will be at CQ=74, 78, 82.
The results will be posted after each run.
Saludos!,

Nope! This numbers are for 352x480, each and every one.
Just your template defaults. Hope this helps.

Oh well, I guess then we can't use a constant CQ change of 4 = +-100MB figure
It really depends on the movie. And all are different!.
But we could use the 100MB as a MAX for a "worst case" scenario.
Most of the ones I've done are close to 100MB.
I think if we use the 100MB per steps of 4, we could stay close to our final figure.
And then we won't have to encode 3 times

Kwag, I have finally tried out your template with a full film (I usually just encode TV episodes) and this is what I've found.
Film : Enigma (Second World War drama about code breaking)
Length : 1hr 53 mins (or is it 50 mins, can't remember)
Format : PAL 16x9 Widescreen.
Encode @ CQ70 - File Size 675 Megs
Encode @ CQ73 - File Size 811 Megs
Encode @ CQ74 - File Size 839 Megs
Currently Encoding at CQ72.
Picture Quality Average At CQ70, but
Great At CQ74,
will let you know what CQ72 looks like in comparison between the two.
Encode Time : 4hrs 20 mins on an AMD 1600 XP system.
Also encoding the film as a 3 disc CVD set so will also post differences in quality with that and KVCD.
Stay Tuned.

The one you did at CQ=73, File Size 811 megs, will burn fine with overburn option. Don't erase it

Hi energy80s !
File with 811mb size could be biger a little so you have cut some titles at the and to 807mb total .
If you want try to burn it don't forget to check "simulate" option (saves CDR )
Good luck !

OK, finally got around to re-coding the Enigma film using CQ72 settings. This resulted in a 773 Meg file (not bad for a film lasting 1hr 53 mins and 52 seconds!) so it will easily fit onto an 80 minute CD-R disc. As for picture quality, it seems similar to the CQ74 encode, and much better than the CQ70 one. I also have the film encoded as a 3 disc CVD set and that does yield better, clearer pictures, but there isn't much in it. So now I have my KVCD burnt, I am going to take it around a few friends DVD players and see if there are any compatibility problems. So far it plays fine on my DVD player (a Cyberhome 52 and Power DVD on the PC.
So Kwag, it looks like the 100 Meg rule might only be +2 rather than +4 for PAL discs as there is a lot more picture to encode than with NTSC. Anyway, I am very impressed with the final result.

Hey thanks energy80s
Those are the tips that are good to have posted, so that we can create more accurate kvcd's
I don't have any PAL systems, so I couldn't make any accurate tests.
Thanks again,
kwag
