Convert OGV to AVI (gtk-recordMyDesktop)

For a while I have been looking for a good way to make some video tutorials in Linux and be able to upload them in good quality to a video hosting site. I finally found a good piece of software that would let me choose where I wanted to record, gtk-recordMyDesktop. This can be obtained by typing sudo apt-get install gtk-recordmydesktop or through the Add/Remove Programs feature. The output of the recorded file is in a .ogv format. I want to convert it to a .avi format so I can upload it. Here is the command to do so:

mencoder -idx input.ogv -ovc lavc -oac mp3lame -o output

There is another way to do this through ffmpeg with this command:

ffmpeg -i input.ogv output.avi

Either one works, but to keep things easy, I made a script to assist with the conversion:

#!/bin/bash
echo "Convert from .OGV to .AVI"
NAME=$(whoami)
read -p "Is the file on your Desktop? (y/n):" DESKTOP
if [ "$DESKTOP" = "y" ]; then
{
    read -p "Please specify the name of the .OGV file: /home/$NAME/Desktop/" OGV
    read -p "Please specify the desired output filename: /home/$NAME/Desktop/" AVI
    mencoder -idx /home/$NAME/Desktop/$OGV -ovc lavc -oac mp3lame -o /home/$NAME/Desktop/$AVI
    echo "Conversion completed."
}
else
{
    read -p "Please specify the location of the .OGV file: " OGV
    read -p "Please specify the desired output filename: " AVI2
    mencoder -idx $OGV -ovc lavc -oac mp3lame -o $AVI2
    echo "Conversion completed."
}
fi
read -p "Would you like to play the converted movie? (y/n):" PLAY

if [ "$PLAY" = "y" ]; then
{   
    if [ "$DESKTOP" = "y" ]; then
            totem /home/$NAME/Desktop/$AVI
            echo "Process Completed Successfully!"
            clear
            exit
    else
            totem $AVI2
            clear
            echo "Process Completed Successfully!"
            exit       
    fi
}
else
    clear
    echo "Process Completed Successfully!"
    sleep 2
fi
exit

Just make sure to issue chmod 755 ogvtoavi before running it.

So now you can expect some videos in the upcoming days...
