Audio sync with windvd?

[MDJones1]

I am capturing avi files with windvd using a canopus advc300 box. The audio is in sync. I am then breaking the file into chapters in windvd, and the audio is still in sync. Then when I author the dvd, the audio gets out of sync. Seems to get further out the farther into the program. Has anyone had and solved this problem before?

What format is the audio in? Is it 44Khz or 48? If it is 44 before you author, the program maybe transcoding it to 48Khz, and causing the sync error. Try converting the audio separately before you author.

I am using the canopus advc300 and capturing audio at 48khz 16 bit stereo, locked mode. Good try, but no cookie for you :P
I am capturing the video as a dv-avi file, and the two are perfectly in sync all the way when played in adobe premiere and windvd while in the edit screen. The sync problem is only occuring in the burn.
Anyone else want to take a crack at this one? Gotta client waiting on a dvd of his performance, and since he is a guitarist, it would sure be nice to have the audio in sync.
Thanks,
Mike

What program are you using to author/encode to dvd? What are your output settings for audio?

[MDJones1]

I am using Windvd exclusively. I am capturing, editing the chapters, authoring the disc menus and burning the dvd in this program. The canopus is a firewire breakout box that converts analog video audio such as from a vhs tape to digital dv-avi.
I have selected in windvd to capture in dv-avi. The audio output in windvd is LPCM. The other choice is MPEG audio. Tried both. Both Failed. So far 8 coaster created trying various things. Intervideo tech support said to uninstall and reinstall the program which I did yesterday. Still only another coaster for the collection.
Thanks for your help with my problem. Hope you can send me in the right direction.

If you are doing NTSC video at 29.97 frames, your audio needs to be at 48hz and lcpm, ac3, etc...

I am indeed using the NTSC format and capturing audio at 48khz and outputting the audio as LPCM as I have stated above. My frame rate is 29.97 frames per sec. Everything in the capture is perfect, and when the avi file is loaded into adobe premiere for editing, everything is perfect. When the edited project is then loaded into windvd to author, everything plays back perfectly there too. Only the DVD that is created is out of sync. I believe it is in the compression from avi to mpeg2.

Wait a minute. If you are inputting the edited AVI file to WinDVD to encode and author, that seems to be where the problem starts. I am understanding the sync is OK to that point? Then the encoding creates the sync problem? Or are you using Premiere to encode and WinDVD to author? They are separate processes. Authoring rarely causes sync problems. It's usually in the encoding and usually from a flawed AVI file.

Try this: Take the raw DV from your transfer and dump it into the freeware DivxToDVD and burn the result. If you have no problems, then your problem is somewhere in your editing/encoding/authoring/burning.

Hi Redwudz,
I am rendering the file in adobe into an avi file. I am then importing the avi file into windvd to add menus and burn. It is in the windvd program that the compression to mpeg2 is taking place, and the only time thru the whole process that there is any disparity in audio sync in on the final dvd. I will try the program you suggested to do the encoding and then import the mpeg2 file into windvd and see if it will then burn a good disk. Thanks for your help
