SVCD, problems with Multiplexing

[uknow]

I can't get the Audio and Video to work together!
They work fine seperatly.

I've made my SVCD with CCE and resized with VDub and everything works up to when bbMPEG mixes the audio and video together and divides up the movie. It makes the video jumpy and the audio doesn't work half the time.
By the way what should the audio size be for a 1:46 minute movie, mine is 93MB in mp2 format, is that right?

Okay, I just tried Multiplexing in TMPG and it too didn't work. When TMPG finished Multiplexing the movie it gave me a message box:

--------------------------------------------
| Warning
--------------------------------------------
| 1023623 s packets cause buffer underflow.
| The MPEG file might cause error when it is played.
---------------------------------------------------------

If you know of other SVCD mulitiplexing software let me know, I could try that too.
Is there something wrong with the movie?
It was dvd-rip divx of The Fast and the Furious 576 x 240, 24 Bits, 153655 Frames, 23.976 Frames/Sec, 108 KB/Sec, DIVXMPG4 V3.
Here are my steps:
1) I use VDub to extract the Audio(Audio>Direct Stream Copy) from the orginal divx, then I use TMPG with toolame for the mp2 compliant sound.
2) I then extract the Video(Video>Direct Stream Copy) from the orginal divx. I take this Divx with no audio and put it into Cinema Craft Encoder SP 2.50.01.
3) I've tried two different times with CCE to encode it. The first time i used VBR 3 muliple passes, the second time i tried VBR single pass with bitrate 3000-6000. And the movie looks fine after both settings.
4) Then i run it through pulldown.exe and it still looks great.
5) When I take the Audio.mp2 and Video.M2v and try putting them together in either bbMPEG or TMPG i get a jumpy, screwed up audio picture and the audio lags behind like the video. Why it doing this?
It works just fine till i try to combine the audio and video.
Please Help, I've been at this for days now

Sounds (and I'm guessing, since your problem of "it doesn't work" isn't too clear), what when you multiplexed, you got an error in bbMPEG saying something to the effect that there's an "underflow" error.

Quick fix:

When you select options, only do the output file name, and select your input video and input audio.

Under "Program Stream Settings", clikc the "SVCD" button. Now, leave everything the default except change the "Forced Mux Rate" to "0" (as in nothing, as in zero).

Start the Multiplex.

It should work properly.

If not, I suspect CCE made an odd stream. I have had so many problems/successes with it it's crazy.

[homerpez]

Good lord. I just looked. You're doing 3000-6000 bitrate for SVCD!

This could be the problem right there... WAY too high... but try the bbMPEG trick anyway...

[uknow]

First of all THANX for responding.
Second, underflow error was from TMPG.
bbMPEG didn't report any errors it just gave me a Jumpy screen and audio that doesn't half work, that was the reason I gave you before guess you didn't see it.

If I don't get any responses within the hour I'm just going to reencode at a lower bitrate..(sigh) for the 3rd time.
I don't understand why 3000-6000 doesn't work anyway, if it plays fine and everything. I mean the only problem is when it's time to put the audio with the video. What do you suggest for good quality SVCD with CCE. VBR 3 multipass? VBR 1000-3000 bitrate?

Just making sure the audio size was the size it suppose to be:
93MB for a 1 hour 46 minute movie, does this look about right?

Hey rob, its me ShiZZZoN

You are doing xsvcd i assume.

dont go so high, u could be corrupting the vid patially in wmp and DEFINITELY not playback in your dvd player

Most or all dvd players cant read above 2500-3000 anyway.
And one more thing- anything above 2000 is unnoticable anyway

[uknow]

hey, LOL your the second person who thought i was rob.
I just couldn't think of a name when i signed on here so i put "uknow".
Thanx for the response just the same.
Guess i'll change the bitrate to 1000-3000, sound good enough?
I didn't understand why the audio and video Couldn't be played together
But played excellent seperatly.
I don't think it was because the computer or dvd player was too slow. Though it could have been, i've no way of knowing for sure because they both had the same reaction.

uknow, your problem might be where you extracted the audio in VirtualDub. You didn't set it to Full Processing Mode for audio, therefore the audio isn't getting uncompressed, and the multiplexing software has problems working with that. That's why the size of your audio file is so small too. Set it to Full Processing Mode for audio and repeat the other steps.

[uknow]

Thanx, it's worth a shot.
and if your correct this site needs to change it's tutorial:
http://www.vcdhelp.com/avitovcdfoolproofusingcce/
The first picture on this page shows what the audio settings are suppose to look like when one "extracts WAV".

[homerpez]

hint...

If you plan on taking that SVCD to your friend's house, your really should use ~2500 bitrate, or less (with 2520 or so as MAX). Any higher, and it may not work for a host of other reasons, than a bad multiplex...

For the V-Dub audio issue, yes you should do "Full Processing Mode" when doing a compressed audio source (like MP3) ... or use Winamp's "DiskWriter" audio-out plugin on the resulting file it puts out. It decompresses most any format it plays into a nice PCM .wav file. Usually in seconds.

[uknow]

yea i did the audio thing. (surprise, still didn't work)
By the way, the latest bitrate i made was 1000-2500, 1800 AVG. and it's still geting a jumpy picture (when I try to multiplex).
Maybe I'm missing something.
I don't understand i followed that guide exactly, and it everything works great up until the Multiplex.

I mean if something was wrong with the video or audio it would happen before i try to multiplex right?
Here are the details on the orginal dvd-rip Divx file:
576 x 240, 24 Bits, 153655 Frames, 23.976 Frames/Sec, 108 KB/Sec, DIVXMPG4 V3.
could it have something to do with progressive or interlaced film?

You're supposed to extract the .wav from the divx then convert it when u'r encoding in TMPG. Try using the toolame encoder for the audio. Maybe you're not setting the right framerate? Maybe your divx player can't support NTSC-Film, try choosing NTSC and set framerate to 24.
