The Basics of WMV Video - The video requires a very large amount of information: 25 frames per second, half a million points on the screen in color to represent more synchronous sound. It's hundreds of millions of bits per second that must be treated or stored.
The video requires a very large amount of information:
25 frames per second, half a million points on the screen in color to represent
more synchronous sound. It's hundreds of millions of bits per second that must
be treated or stored. The signal recorded on magnetic tape for a long time was
a feat of engineering. The rapid evolution of technology has led to a multitude
of standards, some of which have disappeared or are endangered. It is not easy
even for the specialist to navigate.
In computing, the videos are digitized and stored in
files. One of the major disadvantages of digital video is the space required
for data storage. In the uncompressed format, one minute of video can take up
several hundred MB of disk space! Compression systems have been developed: With
these systems, the file size decreases significantly (up to 5 MB/min). In
return, the image quality also decreases, but the quality/size is quite correct.
To achieve this, there is different mathematics
involved. To generate or read a compressed video, the computer must know the
encoding chosen. The coding rules are stored in files called codecs
(coding/decoding) to be installed. An 'Avi' could just as well be encoded in
DivX, in Intel Indeo or DVD. Players that read Avi files use external codecs.
For other extensions (Mpg, Mov, etc ...), the codec is unique. To play a video
encoded with a codec you must have this codec! But everyone does not necessarily
have the same codecs! We must therefore choose between a widespread but
inefficient codec and a good but not widespread codec. A now well known
standard is DivX.
Yes! Just use the right software. Nero or Easy Media
Creator for example, performs this task for you. If you have Windows 7 or
Vista, you do not need additional software. Indeed, these two Windows versions
incorporate a program called Windows DVD creator. It will know what to do with
your videos to WMV. Whatever your choice of software, the indispensable
condition to be fulfilled is that your film must not be protected against
unauthorized copying (DRM).
The problem is that most mobile devices such as the
blackberry only read videos in particular formats and they especially support
avi format. As such, when you are done creating your dvd in the Windows DVD
creator you will want to use a good DVD maker software to convert wmv to dvd format. The most recommended software I have used is
the aimersoftdvd
creator . It is
fast and has an easy to use interface.
When you burn wmv
files with this
application, you can quickly encode various formats format
for your mobile device, Internet uploads or desktop application to dvd.
