This article describes how to convert a dv video (raw) to mpeg4 video with mp3 audio (avi).

 

Step 1: install mencoder

Make sure mplayer is installed on your system.

# rpm -qa | grep mplayer
mplayer-1.0-63_rc2.fc8
mplayerplug-in-3.55-35.fc8
mplayer-skins-1.0-pre3_13.at
mplayer-skin-mini-0.1-11.2.at
mplayer-fonts-1.0-7.at

 

--> you will only need the mplayer rpm because mencoder is part of mplayer:

 

# rpm -qf `which mencoder`
mplayer-1.0-63_rc2.fc8

 

 

Step 2: convert

 

# mencoder film001.dv -mf fps=25 -o film001.avi -ovc lavc -lavcopts vcodec=mpeg4 -oac mp3lame

film001.dv input file (the file you want to convert)
-mf fps=25
output frames per second (25 is the default)
-ovc lavc encode with a libavcodec codec
-lavcopts vcodec=mpeg4 use mpeg4 for video
-oac mp3lame use mp3 for audio
