Audio sync problems

[peter762033]

Hi
ive got a mpg video and the audio is out of sync.The timing gets worse as the video goes on,so at the start theres not much out of sync but by the end its really bad.Is the re a prog which can put it all back in sync?

Drop it into the newest version of Gspot and check the audio VS the video lengths. They are probably different. Easiest may be to shrink or expand the audio time. Mux it out and change it with an audio editor. You will change the pitch if it's off by a large amount. In that case, it may be better to adjust the video length. If the lengths are the same, you have other problems. Check for missing frames.

If it's a video you created, check your process. If you changed the framerate, that could explain it.

no i didnt create the video. This is gona take so much work to get all of this in sync,the vid is like 1 hour long and around 400mb, i dont really know much about this, is there anyone here who is willing to try it for me if i give them the vid?

Are you willing to pay ? I ask only because it may well take a lot of work, and if that time is important to you, it will be doubly so to those who do this for a living. If it is a one off, your best option might be to get a professional to do it. Otherwise, spend some time yourself and learn a few things along the way.

Do a search for reaper , it's an audio tool , similar to goldwave , but free .

well i dont want to pay so il try myself.How can i check for missing frames like someone suggested?

well its going to be tuff to re-sync as the audio hasn't got a constant delay.

you'll need to find exactly the start & end points where a audio delay can be achieved... example... 00:00 - 08:34 = -1500ms
08:35 - 12:45 = -1200ms
'etc'

then once sliced the file into parts where the audio delay is different, add the delay and then re-join the re-synced video clips.

I use VirtualDub, you can preview it before you save, so you can get it bang on...

Forgive me if I'm wrong but isn't this basically the same thread which the moderator(Cobra) locked down until further notice:

If it is,best bet is to wait until you hear from them.Don't want to be get on the bad side of the mods

P.S If you already heard from them and it's fine,then sorry to be a nuisance.

I would rather sweat than pay someone to do this.

fuk that, no offence but stuff like this unless intended for profit should be free.

If you can find a way to get it too me for FREE, i would gladly TRY and re-sync it for u FREE.
