audio synchronization problem

[husvago]

Hello,

I don't know where I make a mistake. I have used the following equipment and tools:

- Sony DVR-240 video camera and Adobe Rremier Pro to capturing
- freeEnc, QuEnc, TMPGEnc Plus Trial to encoding
- VirtualDub to saving audio stream
- GUI for dvdauthor to authoring
- VLC Media Player to checking the result

I would have recorded my VHS video to DVD. Therfore I made the followings:

- I captured the film through the camera (as a video card) with
the Adobe Premier. I got 20GB DV AVI files. It is probably Type2
(Gspot displays this information: Type: OpenDML AVI, FOURCC:dvsd)
Length: 1:31 hour
- After that I tried to encode it different ways:

- with QuEnc, freeEnc, TMPGEnc
- I saved tha audio in wav format and encoded video and audio
separetely.

(My video system is PAL)

But nothing helped me. Namely the audo end the video stream
are not in same step at the end of the film. But

- when I play the avi file it seems to correct (but the mpeg2 is wrong)
- when I split the avi file to more parts and they are encoded particularly
the mpeg2 parts are good.
- when I save the wav file and it's encoded separately it has got
the same length as video stream has. And inspite of this the final
result is same: after DVD authoring the voice was slided from video

I would be grateful for some help.

Regards,
D.A.

Is the audio out by the same amount throughout the video, or does it drift out over time ?

If it is out by the same amount the whole way through, add a delay (either + or -, depending on whether the audio is ahead or behind) and you should be right.

If it drifts out over time it usuallt means you have changed the framerate.

Thanks for your answer.

Unfortunatelly your second version is true. Audio drifts out over time
(delay time are increasing continually ; sensibly after the second
half of the film).

As far as I know I didn't change the framerate (or even I don't know
how I should do it . I always followed the PAL standard in the course of
capturing and encoding. The framerate = 25 fps

I would note that the DV/AVI file is correct, only the mpeg (and or VOB)
won't be good, and if I remember well I can't change the framerate
e.g. in QuEnc

Now, I split the DV file and encode separetely and agter that I merge
again the mpeg files into one big mpeg files and author the DVD.

Thanks a lot,
