Audio/Video-sync batch converting

[Lamur]

Hello all,

Does anyone know a good program to automatic sync the audio steam to the video steam and convert it to a given format and container? By sync I simply mean to stretch the audio steam so it fits the video steam.
For example if I got an audio steam 17 minutes long and a video steam on 18 minutes I would like the audio steam to be stretched so it fits the video steam so they both are 18 minutes long.
The input audio/video is something I've recording myself using xfire.

I know it's possible to do in an video editing program, but I quite a lot of files, so a batch converting would be preferred.


Thanks in advance for you help.
