Sync Audio from one dvd onto another dvd

[oldeschool17]

Apologies if this thread has been done.

Is there a guide/website that shows how to sync audio from one dvd onto another dvd? Are there any specific files on a dvd that contain all of the audio or would i have to rip that audio with a prog(im guessing something on the lines of nanodub or virtual dub?).

To explain further, there are some remastered movies from hong kong that only have the mandarin/cantonese language and english subtitles. Id like to take the audio from the non-remastered dvds(that have an english audio dub) and sync that old audio up to the remastered dvd. To summarize, I would like to add an additional audio option to a dvd. I do not need to create a new menu or layout to the dvd. It can be as basic as possible(no menus needed, just the english audio). Let me know if that explanation makes sense or if I need to explain more. Thanks everyone.

The biggest problem is going to be audio sync, either because the delays are different on the different discs, or because different releases may have different production and distributer credits up front. Both will have to be adjusted for.

Amongst other things covered by this guide : https://forum.videohelp.com/topic234240.html is how to replace an audio track in a DVD while retaining the menus etc. It covers a lot more than you need, so just pick and choose the bits you want.

If I were doing this, I would demux the English audio from the old DVD, then open the first VOB in Media Player Classic using File -> Open File. I would open the English audio in the Dub field, then adjust the delay using the + and - keys on the keyboard. Once I had the two in sync, I would note the delay (shown at the bottom of the status area). If the audio was AC3, I would use AC3delaycut to adjust the delay, then test the new audio in Media Player Classic again. If it is in sync, I would follow the guide (above) to replace the audio.







Actually, I wouldn't bother doing any of this. I would just watch the film with the subtitles on. Most dubbing is, at best awful, at worst, racist and cliched.

Thanks this is the response i was looking for. I agree with the subtitles bit though. Ive grown quite fond of it but the dubbing is for nostalgic reasons. Take care

Good luck. You will need it. You should be aware that the English language dubs are usually cut, sometimes severely, as opposed to the original Hong King releases. This will make synchronizing an absolute nightmare. Even 1 or 2 seconds of missing or extra footage between the DVDs will totally throw off your sync.

If it's any interest to you and you don't know, Dragon Dynasty, Image Entertainment and Media Blasters are starting to release Hong Kong movies (mostly Shaw Brothers stuff) with those old English dubs in addition to the original soundtracks. I will never understand the desire for those English dubs, but I do recognize that some people get serious wood over them.

Yes i know of those, however, they dont carry every release that IVL has done so this is for the stuff that has yet to been picked up. Also, this is an opportunity for me to experiment at how to do this process. Thanks for the encouragement

Thanks for the encouragement

I'm just warning you that it's going to be a LOT of work and you may fail. If you don't like to hear that, that's OK with me because I have no interest in this and whether you succeed or not matters not to me. I'm just warning you that it's not going to be easy, but if you don't mind tearing your hair out over what is quite possibly an impossible task, that's your business. If there are ANY differences at all in the videos, and there is almost a 100% chance there will be, you will most likely NEVER get the sync to work totally correctly. You may get it mostly in sync, but not totally in sync at random parts, again, depending on how much difference there is between your source and DVDs.

Love the brutal honesty. Thanks
