About Video Codecs
Sometimes, even though the video file that you want to load may be stored in one
of the compatible file formats (MPG, MP4, AVI, WMV, ASF, MOV, FLV,
MTS, MKV or DIVX) you may receive a message on the Load Video screen in-
forming you that the “video file cannot be loaded as it has been encoded with a
codec that is not available on this system.”
In general, most video files are stored with the digital video & audio information
in them compressed so as to reduce their file size. There are a wide range of dif-
ferent methods of compression that can be used to achieve this, and files stored in
the same basic file format (such as AVI) can utilise a number of these different
compression methods within the same file format. In order for a computer to play
a video file that has been encoded with a particular method of compression, a
corresponding software component known as a
codec
is required to be installed
on that computer so that it may decompress and play that video. A different co-
dec is required for each different method of data compression.
The MultiScreen unit comes preinstalled with a large number of codecs which al-
lows it to play a wide range of videos saved using the most popular methods of
compression that are available at the moment. However new versions of com-
pression are created all the time, and so if you attempt to load a video which uses
one of these newer methods of compression which the MultiScreen unit does not
yet have a codec installed for, then you will receive the warning message above.
If the particular codec that the problematic video has been encoded with can be
determined, then it is possible to download the required codec from the internet
& install it on your MultiScreen system. After this, the video should be able to be
loaded & played. Contact MultiScreen for some assistance if you find yourself in
this situation. Alternately, the problematic video file might be able converted into
one that uses a more standard codec that is already available on the MultiScreen
unit, using the procedure as described on
