XSVCD - HowTo?

[guru1968]

Hello,

just trying to make an SVCD with higher bitrate (i.e. XSVCD), but:
muxing with bbMpeg as SVCD gives lots of Underflows, muxing as MPEG-2 works fine... Or should I just ignore the underflows?

But then when burning this MPEG-2 (~800MB should fit on CD-R 80)
it creates an image way bigger (>900MB) because of padding or so !?

so, question is:
How to multiplex this higher-bitrate (CCE min=0 max=5000 avg=1800) MPEG-2 stream (audio=224) to fit on CD-R 80?

The mpeg itself is okay (796MB) but after authoring (tested with tscv and nero) the image is bigger than 900MB - why is that?

Is there a basic guide or guidelines how to do XSVCD?
If so - where?

thanks,
guru

Maybe the template (http://www.ttool.de/anleitungen/svcd21e.htm) found here would be helpful but it is for TMPGEnc.
Worked for me.

to anyone interested:

leave bbMpeg settings for SVCD muxing, but:
step-by-step increase the muliplex-rate until there are no more underflows! - works for me...

Don't know if there exists some kind of 'formula' to calculate the minimum mux-rate for any given max. audio-/video- data-rate, maybe, but trying this out always works ;-)

Only stupid thing for bbMpeg is, that it exits after each try, so you have to enter everything again for each try - so it takes a few minutes more, but hey: no more artifacts in difficult material :-D

congratulation you for the discovery!
But if you set the "forces mux rate" to 0 (zero), bbmpeg will moke all thing in one step. I hope you life will be a little easier afterwards.
