OK hi Guys here is my issue... I have downloaded some MPG files, and when watching on my PC there is no problems, but after creating a DVD with TDA, when i watch them on my DVD player, the Audio goes out of sync. My source files as MPG so i do not have an orig AVI to work with can anyone help me please?? Will splitting the audio then doing something with it help, i am confused!!

Do you still have the original mpegs?? Check whether they are out of sync. If so, you can re-sync the mpeg before burning. Use TMPGEnc.

Hi ki, Thanks for replying, amd yes i do still have the orig MPG, but when watched on the pc (b4 making the DVD, just as an mpg) they are perfectly fine, that is why i am confused!?!?

Help pls!

did you encode from pal to ntsc or vise versa?

[aguillon]

Yes that would be my guess too. If you notice your file is slowly going more and more out of synch, it generally means that there's a Pal/NTSC conversion issue.

The problem lies in the number of frames/sec. NTSC most of the time runs at 23.976 frames per sec versus PAL's 25. When encoding a NTSC avi to PAL MPEG the length of the movie is therefore reduced by an order of 4%, while your audio may not be.

Another possibility could be a damaged source file, or a source file that contains VBR Mp3, which quite a few encoders find very difficult to handle.

Hi Again, thanks for the replies.
I did not encode anything, just downloaded the mpgs, then put them into TDA, did the chapters then menus then made the DVD.
Here are the details shown after opening one up in VirtualDUB MPG, and looking at file information, maybe it will help...


Cheers,

audio needs to be 48khz for dvd

[dynamix1]

I have had a similar problems with xvids I used vso divx to dvd, and had sync problems when burning with TDA. It was mentioned to use video redo to correct this problem. I havent tried it yet but just another suggerstion. Good Luck.

OK Stil lgetting the problem, anyone out there can help Reboot, you still around???

Ricky gave you the reason.

Your audio is 44hz, it needs to be 48hz.

Your files are VCD compliant it seems, not DVD.

You need to re-encode the audio.

You can use TMPGEnc for that for instance: use an unlocked DVD template (first open a DVD template, then open the unlock template), set the audio to Mp2 48hz 192 kps (you can use higher bitrate if you want, I do that to keep the file sizes low), then choose to output Audio stream only. You'll get a MyFile.mpa file which is the re-encoded audio.
Use that audio stream for authoring and you should be fine.

Thanks for the reply, and it has been ages but it still didnt work???? When i put them into DVDLab, it says they are MPEG 1 files

It then still says that the audio needs transcoding to 48k, which i do, then it is still out of sync
