This page provides a brief
overview of how streaming video files are created. The next
tutorial will provide more information about the most common
streaming formats and how to include them on a web page.
Note:
The methods below are for creating stored video files for the
purposes of streaming, not for providing live video broadcasts.
Live events must use a streaming server.
There are two ways to create
stored streaming video files:
- Use a conversion utility program. This
takes an existing
digital video file and converts it into the streaming format
of your choice.
- Export streaming files from video editing
software such as Adobe Premiere, Final Cut Pro, etc.
Conversion Utilities
A conversion utility is a stand-alone program
which imports a video clip and exports it to a different format.
Examples include RealNetworks Helix Producer and
Sorenson Squeeze.
Basically, you simply open a file and select which which format
to save it as. You can set various parameters to optimise the
final video. The program will then chug away for some time while
it makes the conversion.
In the window shown here, the pane on the left
shows the original file. The right pane shows the file as it is
being converted to a streaming media format.
Exporting a File
Most serious video
editing applications have options to export video for
the internet. This is often the easiest way to create
streaming video files.

We will use Adobe
Premiere 6 to illustrate the process. Different
applications have different procedures but this will
give you the general idea. You may need to consult your
application's help file for specific instructions.
Open your video clip in
Premiere.
From the File
menu, select Export Clip.
There are several options
- the exact options available will depend on which
plugins you have installed. By default you should be
able to export to RealMedia, Windows Media and Quicktime.
Choose which format you
would like to export. The Save for Web option is
a good place to start - it will give you the window
shown below. |

The
Save for Web window provides a range of
pre-made templates for different formats. You can
also customise your own settings.
Remember, it's
entirely up to you which format(s) to use. When
you're getting started, we recommend creating a
number of different versions in different formats -
experimentation is the best way to decide what works
best for you. |
What to do with the File
Once you have created your
streaming video file, upload it to your website. It doesn't
matter where you put it as long as you can access it from a web
page. For example, you might like to create a folder caller
"media" or "video" and put all your video files there.
The next step will be to create
the appropriate HTML code in your web pages to display the
video. This is covered in the next tutorial.... |
