DVD Audio Out of Sync

[Namie]

I have a DVD but the audio seems to be slightly out of sync with the video (audio comes 0.5 seconds or so earlier than the picture). It's quite annoying because it doesn't match with the mouth and ruins the movie.

Could someone explain to me how I can adjust the time?

Need more info. What DVD? Did you make?

[Namie]

I was not the one that made it. It seems like a regular DVD video, contains .bup, .ifo, and .vob files... what other info do you need?

[Namie]

So could someone help me solve this? With VobEdit I was able to demultiplex the files and now have a .m2v file and two .ac3 files. I don't understand why there are 2 audio files.

What would it be the easiest way to add like a .5 second delay to the audio so video and audio will be in sync? Is AC3Tool a program I would definitely need to use?

[Namie]

Nevermind, I figured it out on my own. IfoEdit is a great program.

Well, what I was asking was if it was one you created or a commercial DVD. If it was one you or someone you know created, then we'd want to know how it was created to figure out where the problem started.

One of the reasons audio and video is out of sync is caused by the DVD player not being fast enough to handle the bitrate.

This specially happens when you create your own video (not just copying a DVD movie to another DVD), and (re-)mpeg it. As you probably want to get the highest quality possible, the codec will generate a file with a very high bitrate. Many (stand alone) DVD players simply can handle these high bitrates.

At least that's what I found out after going completely crazy and blaming my software, my burner, my TV, etc! I always thought that it couldn't be my DVD player, as it would play copies of DVD movies (burned on the same media) without a problem.

Try to find a setting to limit the bitrate.

Good luck!

Oops, small typo, hopefully obvious:

I did mean to say in that one sentence:

Please tell me how you did it!!!
I would very much apreciate it.
Thank you very much in advance.

Hi Pleonasmaticul (spelled ok?,

This depends what program you use to create the mpeg2 files.

If you create your own videos, there sure will be a setting in the program that creates the .m2v files. This is the best place to adjust the setting. Otherwise you have to check the program that creates the final VOB files (or grabs the the video from the original disk).

You have to look for a setting mentioning 'quality' or alike.
The better the quality, the higher the bit-rate and therefor the biggest chance that the video cannot cope up with the audio when playing in some dvd players. So, choose a lower quality, leading to a lower bitrate and better chances to get audio nicely in sync with your video.

It may require some tests before you get the best sync, without moving the quality too low.

In Premiere Pro, you can choose the quality of the generated video files when you select the export function in the file menu. I'm sure you'll find a setting in your program too.

Hope the above helps!

Sorry but it didn't help

I have a movie that's not done by me.
Just that the audio is delayed by 0.8 seconds.
I tried with smart ripper to demux it and then with IfoEdit tot remux it with no delay (because SmartRipper shows me that the ac3 file is delayed with 0.8 secs)
Hope someone can help me...

Okay, I also have the audio out of sync problem. It is a home movie that I captured with ATI 7500 AIW. I used Nero 6 to add chapters and do my burning. When I ran the preview in Nero it was fine. I burned it at 9500 kbit/s. It was a 52 minute video. Also the chapter setting were off on it. The chapters would start further into the movie than what I had set them at. One more thing, it would play fine (audio still out of sync) if I started at the beginning of the DVD, but if I fast forward or jump to the next chapter, it would play back really choppy. I also should mention that I am using a NEC 2500A burner and Fujifilms 4X DVD-R discs. Any help would be appreciated.
