i have a couple of .avi clips in which the sound plays 2 seconds before the video ,so i need a software that can re-sync the sound correctly with the video with affecting the video/audio quality, what program can i use ? /what is the name of this feature in video editing programs ?
* i`m using Ubuntu 10.04
** i noted that the Multimedia & video forum have only threads about problems in playing videos & cards drivers problems , but i did not find anywhere else suitable to ask this question on the forums!

I use avidemux for this. There is a checkbox and a value box on the main screen that you can use to enable audio shifting in a specified +/- number of milliseconds.

Avidemux can re-sync your audio. I'm not sure if it will re-encode though.
Import your video.
On the left, you'll see a checkbox titles "Shift". You want the audio to start two-seconds later. Start with a value of 2000 (2000 ms = 2 seconds). Make sure Video and Audio are both set to "Copy".
If it looks right export your video.
You can also use the command line (untested by me):
ffmpeg -i input.foo -vcodec copy -acodec copy -itsoffset 00:00:02.00 output.foo
You can use MPlayer to test how much you need to change the audio delay with the - and + keys. It will print out a display on the video showing you how much delay you've applied.
