Control output filesize

[guc]

I'm using DVD2SVCD and the TMPGenc
the problem is that in all the manuals i read there is never spoken about the final size of the mpg files i've read the newbie and advanced dvd2svcd manuals and even there no help so i suddenly was digging in the settings of bbMPEG 1.24 wich is part of the dvd2svcd suite and there you can set the maximum multiplexing filesize.
I've put it on 630 MB and then did a 'save settings as default' in the hope that when DVD2SVCD would use it and i would get (a) file(s) that i could burn on cd withoud joining and splitting.

NO LUCK what so ever though :(

I made for example a nice dvdrip of Natural born killers but i end up with a file of 1.5GB wich is just to big to put on 3 CD's so i've to split it up in 4 CD's of 358 MB or something of that size
and that is just waste of cd's

So i'm probably just stupid that i haven't found yet how to control the final filesizes but i can really use some advice on this matter from somebody with a little more experience !!!

Thx very much in advance for all who replies

Hi
Firstly, a warm welcome to the forum.

It appears you still have some learning to do with regards the use of DVD2SVCD.

Don't beat yourself up about being a newbie - it doesn't make you stupid. It just means you've got some reading to do. Perhaps a good place to start would be
this guide (http://www.doom9.org/mpg/dvd2svcd.htm)

You simply select the number and size of the CD's you wish to use dependent on movie length in the bitrate tab and DVD2SVCD does the cutting for you. It even creates CD image files to burn directly to disc so you shouldn't need to edit, cut or alter the mpeg files in any way.

Two points to note are that using TMPGEnc in CQ mode can give unpredictable filesizes and that the SVCD format allows 800MB to be put on an 80 minute CDR as opposed to the normal 700MB.

thx nick for the welcome ;)

The guide you referred to i already read completely thats also the thing that brought me to the use of DVD2SVCD

My bitrate was already conifugered that it should be ok, but that didn't help.
See here my settings:

But i am using Constant Quality with the encoding, i thought that beceause of the 'constant' it would improve the chance of correct filesize estimation. But you say it is not.

:confused: So what do i choose best:
AUTOMATIC VARIABLE BITRATE ? <- if so what CQvalues should i use ? the default?
or VBR ? <- if so how many passes ?


The nero thing i'll test later on i'll let ya know if there are any probs :)

Besides the guide Nick pointed out (read it again, please, and follow the intructions using VBR, easier for starters), you might want to read the sickies in this forum to construct a useful post.

guc,
you choose best 2pass VBR - no probs with file size. As on the point, why you select 740 MB CD size for everything? In fact 740 MB VIDEO data goes in 74 minutes (or 650 MB data) discs, 800 MB are for 80 minutes (700 MB) discs. So as currently the standart are 80 min. discs (74 min become rare stuff ;) ) I would put everywhere in the tab 800 MB.

wel thx you all i'm gonna try some stuff out now only thing i'm wondering is you say 2 pass VBR but in the DVD2SVCD newbieguide(pdf) they say you should put it on 3 or 4 passes what is the effect ? better quality but not so fast encoding ?

[Nick]

More passes = better quality but slower encoding. Maxes out about 4 or 5 passes but I can't see any difference on my TV above 3.

However, of the supported encoders only CinemaCraft Encoder supports more than 2 passes. With TMPGEnc, 2 is the maximum.

[Abond]

As he is using TMPGEnc it has only 2 passes..
And this nice 1.5 GB file should take not more than 2x80 min CD's

thx for the reply people and keep up the good work !
