It's
Getting Harder To Watch Movies (CODEX) |

After
a long, exhausting day you came home, had
your dinner and then sat in front of the
TV looking for a nice relaxing movie. Nothing!
Then suddenly you remembered that you bought
the CD of the new, Oscar-winning movie "Million
Dollar Baby". You took out your laptop,
inserted the first CD and hit "play". To
your surprise, the only thing you could
see was a green screen. You took out the
CD, cursing at the media market that gave
you a "broken" CD for the fifth time. Tried
the second CD; again the frustrating green
screen. First thing in the morning, you
took your "broken" movies and went to the
shop. Having yelled at the owner of the
shop for five minutes, you suddenly noticed
the cynical smile on the guy's face. Having
the opportunity to talk, the shop keeper
said "CODEX".
All you needed were the codecs for these
movies. They were not broken; they were
just coded in a "foreign" language to your
media player. The codecs were the dictionary
that your laptop had to use to translate
the absurd computer language to the nice
scenes of the movies.
Every video, audio, picture or even word
document files are coded in a different
way. In the case of big data entries like
movies, the computer has to use different
algorithms to compress the data so that
the size does not exceed the standard limits.
We see this compression in PDF files (Acrobat
Reader), in MP3 files (WinAMP), in MPEG
files (movies), in each and every data storage
file that you can imagine. While the compression
is being done, the programs use some kind
of a dictionary. Without these "dictionaries"
(codecs in the case of video and audio files)
the code would seem as meaningless to the
player or the viewer as it is to you. So
you have to install certain codecs to be
able to use certain files.
Some codecs replace the repetitive symbols
over the file, ome codecs changes the aspect
ratio of the movie; some of them decrease
the quality of the picture and yet, all
of them turn gigabytes of data into fair
size that can fit into a CD or a DVD.
As the user demands increases, codecs are
multiplying in a logarithmic scale. There
are several codecs that are musts for movie
fans, however. You should install most of
these if you don't want to be disappointed.
1. MPEG4 - It is the default codec which
is already included in WMP.
2. DIVX - A series of sound and display
codex which come with shareware DIVX player.
3. XVID - Relatively new, one of the most
used video codecs.
4. AC3 - Most common sound codec.
5. Intel Indeo - Rather useful series of
codec which a new version pops out everyday.
Overall the way movies are encoded is changing
day by day. Everyday we see a new aspect
ratio. Everyday we encounter a new codec.
To many, it would seem that it is getting
harder and hard to watch movies. The least
you can do is to download a codec viewer
program which would help you on your quest
for a pleasant evening.
