Synchronize audio and video

J_L · 04. Jun 2009, 05:00 AM

Currently I have some avi files which has the audio around twice as slow as the video. It sounds horrible, and continues after the video ends.
Please instruct me of a way to correct this. I'm a total newbie at video/audio editing.

Maybe you can try iwisoft free video converter.

I copy the method from its FAQ as below:
3. The source video file is not audio-video synchronous, can I fix it?
- Yes. Highlight the video file and right click on it. On the popup menu select "Advanced" item. Then you can set audio delay number in milliseconds (1 second = 1000 milliseconds) on the following dialog box. The value can be zero, positive or negative. For example, if you set the audio delay number to 200, you will hear the sound 0.2 second later than the number is 0 when a specified video frame appears. BTW, some video file already has audio delay info, so sometimes when you open this dialog you may see there is already a nonzero number on it.

But I don't have such a problem, so I never use this function. But this freeware can perfectly convert and edit my videos.

Hope it works correctly on my 64-bit system.
