Much like graphics,
video files can be part of Web pages.
Also like graphics,
the problem is that video (and other multimedia) files add to
the time it takes a browser to load a page.
The latest browsers
can play some video files directly; older browsers require separate
programs or “plug-ins” in order to display the files
correctly.
Much like graphics,
there are several different file formats that can be used to show
video files on a Web page, and also like graphics, each file format
has its own advantages and disadvantages.
