Hi,

I'm new to linux so I hope this is an easy problem.

I'm running Fedora. Details are :
 Linux 2.6.35.11-83.fc14.i686 i686
 Fedora release 14 (Laughlin)
 KDE 4.5.5

My installation was done using root: yum install ffmpeg

I'm trying to convert an AVI to mpeg to run on an ipod touch using the
following:

[root at Len efox]# ffmpeg -y -i
Star.Wars.The.Clone.Wars.S03E05.HDTV.XviD-2HD.avi -b 768000 -s 480x320
-vcodec libxvid -ab 128000 -acodec libfaac -ac 2 -f mp4
Star.Wars.The.Clone.Wars.S03E05.HDTV.XviD-2HD.mp4

The result is as follows:

I got the cmd line settings from the internet but cannot remember the forum.

Can you suggest alternate options to make this conversion?

Thanks
