Cybershow example 1:
G2 version: requires Real G2 player.
To install the new G2 player:
Real player 5.0
- Click on Start menu,
and choose Run...
- At the prompt, type
- Double-click on the
to run the G2 player installer.
If you don't have the Real
G2 player installed but would like to see how it works first, click here
to see a ScreenCam (~5MB) showing how the Real G2 player works.
Creating a G2 Streaming
slideshow with synchronized audio, step-by-step:
- Preparing the slides:
Preparing the audio:
- Create slides with
PowerPoint. Save it as HTML (File, Save as html...). It will save the slides
as gif or jpg files. It will automatically name the gif or jpg files of
the slides numbered as, for examples, img001.gif, img002.gif, ... or sld001.gif,
sld002.gif... depending on whether you choose the non-frame or frame version
of your PowerPoint html.
- Copy all the gif or
jpg file of your slides onto a directory on your www-home.
Preparing the smil file:
- Record the voice-over
with SoundRecorder (included on all TPs, under Start menu, Program, Accessories,
Multimedia) or SoundForge as an .wav file. You can record separate audio
clip for each slide, or one big audio for the whole slideshow. The above
example is a one big audio.
- Jot down the start
time and end time and the duration of the audio clip for each slide. SoundForge
and SoundRecorder both show the timer.
- Convert the wav file
into an .rm file with RealProducer G2 available at http://proforma.real.com/mario/tools/producer.html.
- Copy or move this .rm
file onto a directory inside your department directory on the \\acad1 (Network
Neighborhood, Entire Network, wfu, Acad1)
The smil file is a text file, like an html file. It defines the audio and
slide synchronization. Click here to see the .smil
file (as a text file) for the Cybershow example above.
Finally... You can create
a link on a web page to link to this .smil file. When people click on the
link, if they have G2 player installed, it will asked them if they want to
open or save it. Either way, they will be able to play your streaming slideshow.
Alternatively, they can also run the G2 player directly without going through
Netscape, and enter the URL for this .smil.
- As a quick start, you
may use a template .smil file. Click here
to download a MS Word form we created for the above Cybershow example. Modify
the form items (shaded) of slide URL, filename of the .rm file, URL of your
.rm file, etc. If you are not sure what the items are, click once on that
item, and hit the F1 key. An explanation will appear on screen.
- Save the finished form
as a text file (DO NOT save it as .doc file). It will warn you about losing
the formating. It is OK because you want a plain text file.
- This text file will
have an extension as .txt. Rename the file to change the extension to .smil.
- Copy or move this .smil
to a directory on your www-home, preferably in the same folder as your slides.
Note: Why are
the slide graphics and the .smil file on the www-home while the .rm file on
The .rm file has to be on \\acad1 because \\acad1 is running the G2 server but
the www-home is not. So, only \\acad1 can stream the .rm RealAudio. Technically,
you can put all the slides and the .smil file to the \\acad1, too. However,
\\acad1 does not have as much space as the \\acfiles, where your www-home locates.
It is also that currently \\acad1 has been serving for the departmental files
rather than personal course materials.
