Problem is how to join those three avis (xvid+ac3) to one .avi ?

Don't do it, this can lead to synch problems. Create separated scripts for each movie, or one script loading them all:

Avisource("part1.avi")++Avisource("part2.avi")++Av isource("part1.avi")

This is to process the video. To the audio, you have to extract using VirtualDub, remove the wav header using AC3Fix and join using copy/B, to transcode later to MP2. Please read my guide for more info on this:

I followed your instructions and...... only problem seems to be subtitles...

I got subtitles to sync very well for single cd:s, but when joining cd1.sub...cd3.sub together and run avisynth script Avisource(cd1)++Avisource(cd2)... that joined subtitle file is not anymore sync with the result. (and yes I tried that SAMI subtitle too )

I tried that ++ combining to textsub option too, but got very long movie... It did somehow joined those .avis couple times in a row that movie was about 6 and half hours long.

Well I am thinking to quit with this 3 CD version and get that 2CD version.

For joining subtitles you have to use "Subtitle resynch" or "Subtitle workshop".

But you can also try this :

Avisource("part1.avi").Textsub("sub1")++Avisource( "part2.avi").Textsub("sub2")...

well well... thanks... now it works...

The only problem is that if you filter after that, subtitles will also be filtered and may look bad... If you're using CCE, you can load multiple AVS to create one MPV, but I guess this can't be done with TMPGENC. Please report if the subtitles got blurred after using Dialhot suggestion, I am curious.

They will be (more or less, following the script used).

No we can find other solutions more complete but much more complicate also. Just to avoid a little bluring...

I'm sorry but the best solution for me is to join the xvid first. If virtualdubmod can't join ac3 sound, you can work with an intermediate uncompressed wav.

Xvid AC3 -> extract AC3 in PCM wav (vdubmod) -> Xvid WAV (vdubmod) -> joining all three XVID (vdubmod) -> you wil have one Xvid with WAV sound that you can handle without any problem.

DialHot,

I hate to be ruining your suggestions, but joining XVid/Divx files sometimes lead to desynch...

It can't if they use PCM wav audio. The problems are with VBR MP3 that are very badly handled by vdub.

But in fact, my solution won't avoid the problem with the subtitles

Finally, the best solution if redoing the sub synch with "Subtitle resynch".

Dialhot,

Yes, we both missed the point. Just to put it all togheter, the best would be:
If using CCE: Create two scripts and join then using CCE interface. This works perfectly with no pause between two parts.

If using TMpgEnc: Join Subtitles using subtitleworkshop or something like that.

Ps: great info about VBR MP3, I didn't knew that.

You have an option now in vdub (taken from vdubmod that took it from nandub ) to try to stay in synch with VBR MP3. Don't know if it works correctly.

The same problem exists in avisynth (see the command EnsureVBRMP3Sync).
