Audio Sync Problems

[SHARKO]

I'm using svcd's I've downloaded, maybe this is the problem, but the end result is the audio is always off. I've tried vcd gear to mpeg or tmgen. to re-demutiplex to mpeg. Or just recoding with DVD templates to remux(re-encode). I do not join mpegs first. Also tried SVCD2DVD and even selecting each part separately still causes audio sync. I've used every guide I can find even "surefire." With tmgen. I've split the audio to .mp2 and video to .m2v and tried both mastro and ifoedit to compile DVD file structure. With no luck I love this program "SVCD2DVD" it's easy and was hoping this would be solution, and I was going to buy full version but I am having this result so I question it. I'm not a newbie, but not advanced either. 'Please advise" sorry for puctuation and my confusion

This is how I fix these sync issues. I bet the mpegs are TV episodes, this almost always happens to my Tv episode mpegs when I try to de-mux then re-mux them.

If you open up the original mpeg in Virtualdub and press Ctrl+R virtualdub will bring up a framerate conversion window. Note the number to the right of where is says "Change so video and audio durations match", it will be different from the framerate the mpeg is supposed to be, eg 30.005 instead of 29.970 for NTSC video.

Next you need to save the audio as an uncompressed wav file. So in virtualdub choose file->Save WAV. let it uncompress and save, you will need alot of space.

Now get a program called goldwave www.goldwave.com and open the wav file you just created.

Next you need to do a sum. Take the framerate of the mpeg and divide it by the number that you get from virtualdub then multiply by 100, in this case its (29.970/30.005)*100. Write down the result, again for this example it would be 99.883.

In goldwave click on the little clock icon for Time Warp, under where is says "Specify new relative change or length", for Change % type in the result of our sum.

Next click ok and Goldwave will do its magic. Once it is finished you will have to re-encode the wav file to an mpeg2 audio file with whatever software you want, and then re-mux the new mp2 audio file with mpeg video stream from the original video. You should now have an mpeg that is in sync and you can do what ever you want to it.

Note, if you want to go from 44100Hz to 48000Hz, you can do this in goldwave also.

Good luck
