Video as a multimedia component

Video is a versatile part of the multimedia. It is often the ultimate multimedia end product in which all multimedia elements are used, but video can also be part of a multimedia presentation.

An analog video signal contains color and brightness of the recording and can be displayed in 2 or more channels such as in component video and S-Video or via 1 channel as in composite video.

Digital video is a representation of analog video via binary computer code. This makes video files more manageable, editable and easier to distribute.

The use of codec (coder-decoder – packing and unpacking) creates small manageable files, which can be sent faster over the internet for example.

Known codec formats are:

– MPEG2
– MPEG4
– Windows Media format
– Real Media
– Sorenson
– H.264

Codecs can use, among other things, the following video containers:

– QuickTime
– AVI
– DivX
– Ogg
– ASF
– RealMedia
– Matroska
