Hello all

I know this may have been asked before, but this forum is huge.

I have a problem when burn a mpegII file to cd using nero. The file is perfect and encoded with tgmpeg into svcd format.

when i split the file all went ok and the sound is still perfect.

when i burn the movie however the sound is way out of sync with the movie. Nero does its little converting of the file to make it compatible with its svcd, and then burns.

Any ideas? the systems involved are a 2.4 Intel and a 2100+ AMD system. should be anything with the systems. they do have the same copy of nero on them. could it be the mpeg codec from nero?

any help would be helpfull

Since you have been creating your mpeg-2s with TMPGEnc, Nero should not be *touching* them with any codecs of it's own! TMP is a superb encoder that creates fully-compliant video and audio streams on its own by use of its internal templates.

If Nero *is* re-encoding your files, I can only assume it is because the program 'feels' your files are not in the proper form. (Just a guess). I have Nero Express but I don't use it; I don't like it. Anyway, do you find it takes a *huge* amount of time to burn your final discs? If so, Nero must be re-encoding them. Why do that twice? You already had to sit through the encoding process once with TMP. If you let Nero do it again, you're going to wind up with degraded picture quality.

If Nero won't accept your TMP-encoded files as provided by it's standard, internal templates without re-encoding everything all over again, I'd look for another burning program.

(Other than that, there are about 200 different reasons why your a/v sync could be off.)

Always do a short test encode/burn on rewriteable media *first* before doing any wholesale backups!!! TMPG will allow you to adjust the a/v delay for any encode session. I have learned to 'play with' (adjust) those a/v delay settings a LOT. Seems no two dvds are alike, and all have varying delay values. And you *cannot* go by the a/v delay times reported by various Rippers either. (Like SmartRipper).

You'll just have to experiment, KrOnOs.

Thanks for the help, i figured it out ( by luck)

I realized that when i made my big svcd mpeg file, i calculated wrong ( somehow thinking i could normally place 800MB on a cd )

to what was happening was that the mpeg chunks were too large and nero was shrinking the size down. as well as messing up the audio.

i split my movie into three and the vcds burn just fine now with no encoding

(wow) - I hadn't thought Nero would be that advanced (to know enough to automatically shrink a file if it is a tad too big.

Btw, just as an offnote, an 800meg file, believe it or not, should (barely) fit onto a 700 meg disc because of the way vcds and svcds are recorded to disc. (Less error correction, as in data discs, provides a little more storage space - just like red book music cds).

(Congrats, though!)
