Video and Audio different length

[pchan]

Hi,
I have a video clip that is out of synch. The video file is 1hr 1min 37 seconds and the audio file is 1 hr 1min 20 seconds.
Is it possible to stretch the audio file with 17 seconds ?
Thanks in advance.

Is it possible to stretch the audio file with 17 seconds ?

Yes, of course. You can use Audacity or just about any WAV editor. But are you sure the problem isn't that you just need to set a correct delay? It's not unheard of for audio to be shorter than video and also to be in-synch.

Of course, if the audio gets more and more out-of-synch as the video goes along, then you have to stretch the audio.

Hi manono,
I have been fiddling around with Audacity but just couldn't get it to stretch by 17 seconds.
Any tips would be much appreciated.

Open the WAV file in Audacity. Go Effect->Change Tempo (which changes tempo without changing the pitch). At the bottom, 'Length (seconds) from (original) to (original+17 seconds)'. You can also do it by percentage change.
