Sound synch problem, when two files merged

[iporton]

I have the following problem:

I use TMPGenc merging parts of MPG, converted from AVI. Both parts, when run separately have no problems. But when I merge them, there's a significant sound synch disbalance in the second part.

How to deal with it?

How to deal with it?

Reminds me of an old joke...

Patient: Doctor, it hurts when I do this.
Doctor: Well, don't do that.

Cutting and joining mpegs is fraught with peril, avoid it whenever possible. If you're making a DVD then let the authoring process "join" them.

It is very nice joke, but in this case It doesnt really help. I DO NOT make DVD.

I'm trying to create SVCD. And if TMPGEnc has this feature, what is it for?

[ZippyP.]

Womble is the best for cutting/merging mpegs, everybody has trouble with TMPGEnc's mpeg tools. I still say you can author your mpegs together instead, try VCDEasy.

Good Point iporton.

Ive seen so many good reviews of TEMPGEnc in here, and the so-called wonder of Muxing. But like you say, if TMPGEnc has this feature, what use is it if it doesn`t work.

There's a couple of things that TMPGEnc doesn't like: mpegs created by other programs and VBR encoded mpegs. TMPGEnc is a good encoder but a crappy editter.

"There's a couple of things that TMPGEnc doesn't like: mpegs created by other programs and VBR encoded mpegs."

I am having some strange synch problems when making DVDs (strange in the sense of that they don't happen all the time, with the same settings used all the time), and I think that most of them happen when I'm trying to author them in a software that wasn't used for capturing. TMPGEnc is the worst, giving me the baddest synch. - I don't use it at all.

I'm using Cyberlink PowerProducer 2 for capturing (it's easier and it came bundled with my capture device) but its default templates are so ugly that sometimes I author the DVDs elsewhere. The files are in synch when viewed anywhere before burning or doing anything with them (any editing). After creating the DVD folders, there's the problem. I usually capture using the "high quality" default (1 hr, 8000k/s max), NTSC, and I think they are always encoded as VBR (which might be the cause?).

What is strange is that this same setting work today and doesn't work tomorrow. If I use any other tool for authoring, the amount of synch problems varies (it may even not happen at all). I first suspected of chapter addings/movie splitting, but it seems that it doesn't make a difference. I had movies that had the first chapter in synch, then the rest of it was out of synch, and the inverse - just the first chapter was out of synch.

None of these problems happened with files downloaded elsewhere or while trying to convert movies, I am just burning content of my own VHS tapes or laserdiscs. I'm not doing any file converting, they are all burned as they came out of the capturing, and it has happened with PAL encoding (which has additional problems) and NTSC. Also, I've noticed that sometimes some of the other softwares try to reencode the source even if it is MPEG compliant - I have also noticed that if the audio is converted from PCM to MP3, there are even more problems of synch.

As for the softwares I've used for authoring, I tried almost everything from Ulead/Cyberlink and TMPG DVD Author. If I stay with PP2, it works... but these templates are really ugly.
