codecs such as mjpeg,
etc.
- WMV (.wmv): More or less
MPEG4; can contain nearly

- Synthesis
- Visual multimedia source that
combines a sequence of images
to form a moving picture. The
video transmits a signal to a
screen and processes the order
in which the screen captures
should be shown. Videos usually
have audio components that
correspond with the pictures
being shown on the screen.
