Delay audio mpg

[Creed92]

Hello
I have an .mpg file that has the audio too early in comparison to the video
This happens even after the first half of the video, How I can re-combine audio and video properly with the correct timing without loss of quality?
I have Imago Mpeg Muxer but it doens't has fix options or something
Help me please, thanks a lot

What does that mean? It's in synch until halfway through? It's out of synch by the same amount all the way through? It starts off in synch but gets more and more out of synch as the video goes along?

Anyway, the usual procedure is to demux, fix the audio, remux. The video remains untouched and, if you're lucky, the audio doesn't have to be reencoded.

IF the audio is out-of-sync by a constant offset, THEN you can use mplex:

--sync-offset|-O num ms|s|mpt|c
  Specify offset of timestamps (video-audio) in mSec

--subpicture-delay|-d delay [ms|s|mpt|c] [:stream-id] [, delay[:stream-id]]
  Specify offset of timestamps (video-subpicture) in msec (default) sec, mpt or clock-ticks

I think that It starts in synch but gets more and more out of synch as the video goes alon, precisely from the first half.
I have mplex.exe, but I don't understand what commands I must replace in the quote, the various numbers and things that I have to change

precisely from the first half.

It seems you have a file which is the result of "part01.mpg" + "part02.mpg",
and part01 = in-sync, but part02 = out-of-sync.
So you would have to find the exact point between part01 and part02,
separate them, fix part02, and then do "part01.mpg" + "fixed_part02.mpg".

Say, there, Creed, rather than have a half-dozen or so people trying to figure out Precisely WTF your problem IS, rather than trying to solve it, you need to take some time and explain clearly and plainly what the hell is wrong???

Try just using YES or NO to the following questions, your attempts to further explain have, so far, been less than helpful.

Do you have one single file?

Do you have more than one?

Is the audio out-of-synch AT THE BEGINNING of EACH PART? Specify for each separate file.

Does the audio got more OOS as the video plays? Specify for each file.

Does the audio remain in-synch for a period of time and AFTER THAT gradually get worse? Specify for each file.

Did you make this file or files yourself?

Do you have one single file? Yes

Do you have more than one? No, it's a single mpeg file

Is the audio out-of-synch AT THE BEGINNING of EACH PART? Specify for each separate file. Is a one single mpeg file

Does the audio got more OOS as the video plays? Specify for each file. The full duration of the video is 35:50 min, the audio starts to goes out of synch from 15:05

Does the audio remain in-synch for a period of time and AFTER THAT gradually get worse? Specify for each file. Until the minute 15:05 is everything all right,after that the audio goes out of synch

Did you make this file or files yourself? No

Answers in quote. sorry for my bad ensligh, I'm italian and I can't explain well
