Multimedia consists of
different media forms,
including audio, video,

Each type of multimedia
has it own guidelines for
use.

elements such as graphics,
text, audio, video, animation,
and interactivity by means of
computer technology. (p. 244)

Multimedia Design Guidelines
Always consider file size
and download time when
using multimedia files.
Using streaming media
with a codec can reduce
the user’s wait time.
codec Compression and
decompression scheme
used with streaming media;
the Web server breaks the
transmission into pieces,
allowing the media to
display more quickly on the
user’s screen. (p. 245)

Evaluating Multimedia Web Sites
When you plan a multimedia Web site, ask yourself the
following questions:
• Do the multimedia files support each page’s goals?
• Are the pages cluttered?
• Do any media components distract visitors?
• Does the site give you the option to skip clips?
• Do components such as sound and video work correctly?
• Do the media components add to the enjoyment of the site?

Audio and Video Files
Many audio and video
files require a plug-in to
play. You can download
most plug-ins for free from
the company’s Web site.

Creating and Adding Audio Files to a Site
To create sound files, you will need a microphone and an
audio application to record audio and save it in a file.
You can incorporate sound into your Web pages in two
basic ways:
1. You can create a button and link a sound file to the button.
2. You can set the sound file to play automatically when the page
loads.

Creating Video Files
To create your own video
you need either a digital
or analog video
recorder. If you use an
analog video recorder,
you must translate the
video into a digital format
using a video capture
card.
digital video recorder A
device that creates digital
video that a computer can
use directly. (p. 253)
analog video recorder A
device that creates analog
video. This video must be
translated into a digital
format before a computer
can use it. (p. 253)
video capture card A circuit
board that can convert
analog video to digital video.

Adding Video Files to a Site
It can be challenging to include video clips on a Web site.
Many designers provide a link to the video clip to make
them easier for the user to access, rather than starting
when the page opens.

Animation Files
You can animate both
graphics and text on your
Web site. The simplest is
to animate GIF files.
Another popular animation
tool is Macromedia
Flash. Flash files are
more sophisticated than
animated GIFs and often
have a faster download
time.
