first let me tell you i dont need like a long explanation for this (but it will be good if i had one)
i have an apex1010w and most of my material is ntsc, if that means anything as to why i dont need some of the following.

im sure many people would love to see some of these added to the faq.

i have already tried searching the forums but theres not really a satisfactory answer (or one i could understand anyway) for the following i think it will be cool if there was a sticky about this things:

why must we use bbmpeg to mux and not tmpgenc mpeg tools?
(ive muxed with tmpgenc and see no apparent problem so far)

why do we have to mux as svcd? in what circumstances needs this to be done?
does this apply to mpeg1 also? or just ksvcd?
the subtitle guide also (for switchable subs) is it valid for kvcd or only ksvcd?
(ive never done thiis and also have not had any problem so far muxing with tmpgenc)

is there really quality advantage in using ksvcd over kvcd?
im under the impression that using mpeg1 vbr will be same as using mpeg2 vbr, am i wrong?

will using the adaptive script do lot better than just playing with tmpgenc settings (cq etc)?
(i know trying will be definitive better answer, but i would like to know from your experience, looks like default template kvcd3 settings are good enough)

and a bonus question
wich tools of the ones around here works better or easier for creating kvcds without using like 10 diff utilities (see some tutorials, calculators, filters, muxers etc etc) again , i use tmpgenc for everything except audio encoding i use besweet for that or even dbpoweramp (please advice on dbpoweramp mp2 quality)

thank you in advance for any answer you can give without sending me back to the forum search or posts that has so many replies that i end up more lost than i was.

ok
DIALHOT was kind wnough to answer me most of this already
thanx and sorry for posting in wrong place, for a newbie that needs help that seemed to be the perfect place to ask.

Me neither. But some people reported some problems on some standalones with Tmpgenc that have been solved by using bbmpeg. And there is no reported cases of the opposite. That is why bbmpeg is a better choice than TMPGEnc.
But, as you do, I mux everything myself with tmpgnec.

All depends on the standalone. Some doesn't like at all that you go to far from the standards in VCD but they accept anything in SVCD. Others doesn't even play regular SVCD so you have to do everything in VCD.
And some accepts anything

In theory all MPEG1 has to be done in VCD, all M%PEG2 in SVCD. But... I personnaly dop anything in MPEG1 SVCD muxed with tmpgenc
My SPA is a pioneer btw.

Definitely wrong.
You will never have such quality with standards MPEG1 or MPEG2 for a 1h45 movie on one CD in 544*576. Just remember that regular SVCD is 45 min in 480*576 on a disc !

Yes it will.

I do not use any automatic tool. And I still need only 6 tools : DVD2AVI, NOTEPAD, TMPGENC, CQMATIC and BESWEET.

btw DIALHOT
i didnt understand this part (wich is "such quality")?:
i know there are diff templates for kvcd's, so that resolution part you answered got me a little confused for me SVCD is 480x480 (im in ntsc area) , so maybe i should retype my question a little different

using kvcdx3 wich one will give me better results the mpeg2 or the mpeg1 since both are vbr?

thank you for answering so quick.

Things are the same in PAL or NTSC.
If you want to understand this better just trust these numbers : with the regular SVCD template of TMPGEnc you can easily put 45 minutes of really good video on a disc, isn't it ?
Okay, now just take the KVCDx3 template and change the resolution to SVCD one (that is 480x480 in your area). With this, and by using all the scripts we provide here, you will put 1h45 minutes of video with the EXACT SAME VISUAL QUALITY than you obtained just above.

MPEG2 starts to be better than MPEG1 above an average video bitate of 2300 Kbit/s. To put a complete movie on a 800 MB disc, you have to use avg bitrate near 900 Kbit/s. So for KVCD, MPEG1 gives better results.

Hi:
But, what will be better? 352*288 MPG1 or 720*576 MPG2 (or any other res).
My standalone don't play no standard resolution mpg1 KVCD. If I mux it like SVCD, it play, but with some "interferences" (I don't know what are really, I see it like electronic interference, not blocks) showed in scenes changes. I can mux, and play ok, any resolution in mpg2, without interferences.

For sure anything in 352*288 is lower than in 720*576 and that's not a matter of MPEG1 or MPEG2.
But what is sure also is that you won't put an entire movie in DVD resolution on a CD80 with a watchable quality

Lets compare what is comparable.

I don't know what is "watchable quality" for you. I'm encoding 720*576 mpg2 100/110 min. with audio at 128/160 mhz, and burning it on a CD80.
All my friends think those movies have very good quality. Can I send you a CD for regular mail? In this way I could know how is your "watchable quality meter" (not kidding).

In still scenes, quality is probably sometimes "acceptable". But in scenes with motion... you should see a lot of blocks !

And that is CLEARLY what I call a non watchable quality

@Prodater
Once again sending me anything is not necessary. You're movie can't be as good as you thing they are but your eye isn't as trained as mine, that's all. And that's quite normal. The only valuable thing should be that I watch with you one of your CD to show and explain to you why and how they are bad. Hos is the sea in Palma de Mallorca ?

Well, I want to send you a lot of gifts and you don't want.
Not problem, You are loosing it, not me.

I understand you.
I'll very pleased of meet you anytime, maybe in Mallorca, maybe in Paris.

Do you think that 480*576 mpg2 1 CD80, will give me a good quality?
