Super Duper Script to Convert any Video to iPhone/iPod

I found this excellent script to convert any video to h264/aac (video/audio) in a mp4 container. It has created about 500mb for a 60 minutes dv with 1000 bit rate and 480x340 size. If you reduce the size to 320x240 and bit rate to around 600 the size of the resulting file will dramatically reduce to around 200mb. If you are panning to watch these on your iPhone/iPod this quality is pretty much acceptable. But if you want to watch it on LCD you better go for little larger size and bitrate
Here is the script:
ffmpeg -i "input.any" -r 29.97 -vcodec h264 -s 480x320 -aspect 16:9 -flags +loop -cmp +chroma -deblockalpha 0 -deblockbeta 0 -b 1000k -maxrate 1250k -bufsize 4M -bt 256k -refs 1 -coder 0 -me umh -me_range 16 -subq 7 -partitions +parti4x4+parti8x8+partp8x8 -g 250 -keyint_min 25 -level 30 -qmin 10 -qmax 51 -qcomp 0.6 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec aac -ab 80k -ar 48000 -ac 2 "ouput.mp4"

Please note that if you have the default ffmpeg that comes with ubuntu, the above script may not work. The default ffmpeg does not have codecs like h264 and aac (copyright problems). please follow this Fixing ffmpeg on Ubuntu.

I know it is little intimidating but all I did on my Gutsy was this:
1. Added the necessary repository
sudo wget http://www.medibuntu.org/sources.list.d/gutsy.list -O /etc/apt/sources.list.d/medibuntu.list
2. Get the gpg key
wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- sudo apt-key add - && sudo apt-get update
3. Add the required packages
sudo apt-get install liblame-dev libfaad2-dev libfaac-dev libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev
4. and ran the Ubuntu update manager and installed all the packages
