DVD video playing too fast for audio?

[JoeyII]

Hi all,

I'm new to DVD authoring, but have worked as a programmer so I am somewhat computer literate. I have searched the site some to seek an answer also. I recently captured a concert on television to a DVD compliant video MPEG-2 format, 720x480 29.970 fps, 8000 kbps, and 48000Hz audio 224kb/s audio as shown by GSpot.

The mpeg file plays fine on my computer. So I wanted to put it on DVD for a friend to watch. I used the software that came with my system, ULead Movie Factory Suite Deluxe to burn the DVD and the A/V are out of sync terribly.

The video seemed to play much faster than the audio, so I demuxed the mpg file and got an audio file that was the correct length 1:24:28 and a m2v file that was considerably shorter in length 32:58 and played too fast.

I looked at the GSpot info on the mpeg file again and noticed that it reports the length field for the video as 4:08:01, so just guessing as the novice I am, it seems this video would have to be played faster to squeeze into the 1:24:28 length of the audio?

Anyway, I'm unclear on why the file plays fine as an mpg, yet the video is so out of sync when trying to write as a DVD.

If anyone can offer any help or advice, it would be appreciated.

Thanks,
Zach

Not all mpg2 files are equal I guess is the best way to put it... Especially a problem with mpg2 captures, my guess would be that the flags are wrong in the mpg2 video, complicated by running it thru the ulead app.

You might want to try running your captured video (before or after demux) through a repair prog., or demux thru MPG Tools in TMPGEng, that sort of thing to re-generate or correct those parts of the file that don't contain video frames. You might also want to try using DGIndex & Avisynth to generate an avi file, or as a proxy & re-compressing.

Otherwise might try searching on your capture methods/hardware. AS to why it plays fine, whatever software created the file is also present playing it back.

I would start by running the video through restream to see if it fixes things.

Hope everyone had a good new year. Thanks for the suggestions guys. Will try some things this evening when I get home and let you know. I'm learning by doing.
