Justa quick question about muxing
 
When I do a vcd (mp2 + mpg) the output is about mp2 + mpg in size.
(10meg audio + 20 meg vcd = 30 meg final)

When I do svcd, the output is only a fraction larger than the mpg video file.
(10 meg audio + 20 meg scvd = 22 meg output)

Is that normal, correct? Seems wierd to me, or am i not understanding the svcd format properly?

There is clearly a problem when you do your svcd muxing !
Check your parameters.

Funny thing is, the movie seems to play ok.. maybe the sound dies later on in the movie tho?

I think I'll go back to tpmgenc for muxing (I was using that mplex util than kwag posted on another forum/thread, with its default settings).

That's what I use all the time.
Is your screen set up like this:

Hi,

@kwag when muxing as svcd you filled in 6972 as your forced mux rate is that the same for every movie or is it different because when I use zero the audio dies just after the beginning of the movie

That's the default setting for MPlex and BBMpeg. That's what I used, and it worked.
You could also try TMPEG's muxer :idea:
Just run TMPEG, /file/MPEG tools/Multiplex, and mux as SVCD.

Allready tried that but it didn't like my *.mp2 file :( . I think there's an error in it somewhere but I tried ripping out the wav with virtualdub and then converting it with besweet but it gave exactly the same error as the mp2 file I got from directly using besweet to make the mp2 file. Is there someway you can fix your mp2 file?

I always use Mplex to mux but now nothing is working :?

When you extracted the audio with Vdub, did you check "Full processing mode" in the audio tab :?:

I'll try that tomorrow :) but I'm tired and going off to bed now.
Good night or morning or afternoon :P

Does tmpgenc say something about 1/2 way through about an error in the mp2?

I've had that on 1 in every 4 or 5 besweet files - I think it's a besweet bug ** (but no one will admit it :lol: ). I've switched back to headac3he.

(** it could also be a toolame bug - that's what I used to use, no i'm using mp2enc).

Tpmgenc nearly always says about 200 - 2000 underflows, but the mpg plays just fine after - I ignore those errors.

<edit> hey! the quote didn't work!??

Koekies 05-08-2004 09:21 AM

@Fluffbutt thats exactly the error I had

But It worked now :)

I tried it a bit different than kwag said :P I used bbmpeg to make an mp3 file of the audio and used nero to convert it to wav and besweet to convert it mp2 it worked perfectly. But if you extract the audio with virtualdub like kwag said with full processing mode on it will also give a huge wav like nero did and its alot quicker than doing it my way. I don't think its really an error in besweet I think theres an error in the audio part of the avi and if you copy the stream directly without converting it to a huge wav you will copy the error in the audio.

So what I suggest you to do is load your avi in virtualdub in the audio tab select full processing mode then in the file tab select save *.wav.
Use besweet or headache(never used it but i guess it isn't that different) and convert it to mp2 and use mplex to mux.

I think the bug is in toolame.dll.

I've tried it with avi2dvd's ac3 output (in stream demux) to mp2 AND in a direct from vob conversion to mp2.

The bug goes away in besweet when you tell it to use mp2enc.dll instead of toolame.dll (the command are the same).

Try

"D:\ForCd_DvdTools_Mar04\Audio Tools\BeSweet 15b26\BeSweet.exe" -core( -input "E:\Movie\ep1 AC3 T01 2_0ch 192Kbps DELAY 0ms.ac3" -output "E:\Movie\ep1.mp2" ) -azid( -s stereo -c normal -L -3db ) -ota( -hybridgain ) -mp2enc( -m s -b 128)

or

"D:\ForCd_DvdTools_Mar04\Audio Tools\BeSweet 15b26\BeSweet.exe" -core( -input "E:\Movie\VIDEO_TS\VTS_02_1.VOB" -output "E:\Movie\Ep2.mp2" ) -azid( -s stereo -c normal -L -3db ) -ota( -hybridgain ) -mp2enc( -m s -b 128)

Your paths to the programs instead of mine, of course...

<edit> Oh, this was from an episodic dvd too, you'll have to join the mp2 from single movie vob's (copy /b vob1.mp2 + vob2.mp2 + vob3.mp2 final.mp2).

I had the same error as you had, just this last week!

Solution: I was using the besweet beta version, I used the stable one instead.
Sometimes there is a bug in the beta like this one.
The mp2 was not completely 'correct' and nothing could mux it.
The stable besweet does have a problem with some ac3's. In that case I use the beta one - usually it does work. When it doesn't, I use the beta to create a wav which I then convert to mp2 using the stable besweet. Sounds complicated but it isn't.
