Web-optimized audio/video formats
There are several formats for delivering video and
audio for the web. They include Windows Media, QuickTime,
RealMedia, and Adobe (formerly Macromedia) Flash. Although there are advantages and disadvantages to each
format, we highly recommend Flash due to its compatibility
on different computers.
We also recommend QuickTime as it is also available
for multiple platforms. It deliverers remarkable quality
through its MPEG and the new H.246 codecs, although not
as commonly installed as Flash.
About audio/video for the web
Download vs. Streaming
With video for the web, there are two options. Downloaded video/audio, regardless
of the format, must be downloaded through the media player completely before
it can be viewed. Streaming video/audio is downloaded in fragments as the
user views the movie.
The advantage of downloaded video/audio is that it allows
you to present the media in higher quality, but it is
more suitable for short videos. The advantage of streaming
is that it allows for longer videos to be viewed on the
web, but quality is sacrificed in order to accommodate
dial-up internet users.
Quality of the Source
The source media has a large effect on the quality of the web-optimized media.
High quality source audio/video results in high quality web-optimized audio/video.
For example, a Digital Video version is preferred over DVD version, and a
DVD version is preferred over a VHS version.
Other Considerations
The quality of the web-optimized version will vary based on several other factors.
First, consider your target audience. If most of your
users use dial-up internet connections, you will want
to deliver audio/video that can played on a computer
with a slow internet connection. This means that the
size of the video will be smaller, the quality will be
less, and the video will be played back at a slower rate.
If most of your users are on high-speed internet, your
video can be played at a larger size, at better quality,
and at a higher rate connection. Another common option
is to provide two or more versions of the audio/video
to cater to both types of users.

| DSL (med) |

| DSL/Cable (high) |
450k |

Next, consider what hardware most of your target audience
is using. For example, the average PC user will probably
use Flash and Windows Media (ships will all Windows XP
PCs). If most of your users are MAC users, they will
probably use Flash and QuickTime (Ships with all Apple
computers).
However, if you already use an audio/video technology
on your website, you will want to continue to use the
same technology. For example, if you have Flash elements
on your website, it would be convenient to use Flash
as the delivery format for your audio/video project.

we may assist you in your audio/video needs.
