Audio Out of Sync? Encoding or Authoring Issue?

[SIMES]

Hi

For the first time I have ended up with a the sound oround 2 seconds out of sync with the video.

Would this occurr at the encoding stage ( I use Main Concepts Mpeg2 encoder) or at the authouring stage ( I use TMPGenc)

I take it it certainly does not occurr at the burn stage ( I use Nero)

The avi file plays fine via numerous avi players, but when converted to DVD it's a mess.

On the upside 'picture is great'

As well as pointing out whether it's the encoding or authoring stage, I am presuming encoding, can anyone give me an idea as to why this may happen so I can try to avoid it next time.

Never happened before .

Is the encoded mpeg file out of sync? Usually, the authoring program is the cause. Ulead DVD Movie factory came with my card, and I have had files that were in sync before they were authored in MF. I now use the program TMPGenc DVD author, and no more sync problems! TMPGenc has a great deal where you can get the authoring program and the encoder for $99.00! That was a VERY good buy.

Unfortunately like an idiot I deleted the encoded mpg ( not to much space on my machine) so I can't go back and check.

I actually use TMPGenc DVD to author as well, and in fairness this is the first time this has happened to me (sound being out of sync). I may just try and encode it again,I use Main Concepts to encode. So I guess, I will try that again, see if that plays ok, then authour it again using TMPGenc DVD and see what happens then.

Anybody else any ideas?

I've had files that I thought were in sync only to find out later they were not. I now use the toughtest test I could think of. I play my files in Windows Media Player (no comments please) at full screen. During playback I click around on the timeline trying to find problems areas. I'll click way ahead, then way back, then ahead again several times to different positions in the movie until I'm confident there are no problems with this file. If I notice any 'out of sync' while doing this then I know I have a problem. A properly recorded in sync file will play good while you do this operation, if it doesn't then you have a sync problem in the file.

I've found that by just playing a file from start to finish will not 'always' show that it has a problem.

Works for me.

did you demultiplex and re-encode the audio to 48000?
