I am having a problem. I have a lots of VCD tv shows. I want to burn them on to a dvd, and play them on my dvd player. I use ISObuster to extract the MPG. Then I use TMPGENC author program, and the picture comes out fine, but the audio is out of sync, by 1 -2 seconds. I have these programs, Vitualdub, Ulead Movie factory, TMPGENC and the author program. Nothing I use seems to fix the problem. I have tried to rencode the audio from 441000 to 48000, but nothing seems to work, any ideas.
Try downloading the trial of DVD-Lab. All you should have to do is import the MPG file you extracted into DVD-Lab as an asset, and it can do the demuxing and audio conversion for you.
Yes, try DVD lab! I'm curious if it will correct the audio sync problem just by adding the demuxed streams to the project. Each audio stream added starts at 0.00 seconds on the time line, so it should be synchronized correctly from the beginning...however...
If you still need to correct for audio sync, try this:
Once you get your demuxed 48k .mpa/ac3 and .mpv files into the movie time line, you can adjust the audio delay. First, left click on the audio time line to select it. Next right click on it to open a dialog box. Select Audio Delay.
Now you need to add a value to the Add/Remove Audio Delay box. Putting in a negative number starts the audio earlier, a positive value will start the audio later.
Because these audio and video streams are demuxed at this point, DVD Lab does not allow you to preview them to check if the sync is right. You need to have a pretty good idea how much the sync is off by before you start. You can check the compiled project and then go back and change it if you need to though.
You may want to try just a short clip to experiment with until you can come up with a good value for the sync offset that you can apply to the whole project.
None of this is really going to help if your audio goes further and further out of sync as the movie plays though.
I think if I wanted to correct for that, I would first go to the source audio and try to figure out why it is running faster or slower than the video stream and correct it there.
If I couldn't fix it there, I may try and cut the movie into short pieces, correct the sync for each piece and then compile the whole thing back together again. That is probably not the best method though!
