MULTIMEDIA RESOURCE CENTRE

There are multimedia applications in almost every course being given in the College. Applications
range from using a simple piece of audio-visual equipment in a classroom (for example, how to use the
Visual Presenter) to the more complex creation of a video vignette to put on
the website. Teachers will find here a central
place with proper staffing and equipment where they can learn to integrate emerging technologies into
their courses.
Workshops: Workshops are organized on a
regular basis throughout the year. Our next coming presentation will be on the
latest version of SMART Board (version 9).

Facts and Tips on Using
Digital Video on the Web
Video
Vignettes
are
dynamic pieces of information easily produced using simple
techniques. The Multimedia Resource Centre can help you
design the exact presentation for your department or course. These
can be published on the web site, be part of a WebCT course or
downloaded onto CDs for your students.
Basic
Facts:
video vignettes, even short ones, can generate large
file sizes which consume a lot of bandwidth. Consider that a 1
minute full screen digital video requires 200 MB of hard disk space.
This means it requires 1 GB for every 5 minutes of video! Consider
also that a 1.5 MB file takes about 15 minutes to download using a 56K
modem.
What
can we do to consume less digital space?
1)
reduce screen size: use 240x180
pixels instead of the normal 720x480
2)
reduce frame rate: use 15 frames/sec
instead of the normal 30 frames/sec
3)
apply video compression software
like Sorenson Squeeze
Example: a 53
seconds movie that takes 188 MB can be reduced to 1.5 MB with above
parameters (that is more than 125:1 compression).
Pedagogical Consideration
Elaborate
concepts often benefit
from being split into multiple component vignettes with the
technical benefits of producing smaller files.
Technical Considerations
Audio:
Before you start shooting the first scene with a digital camcorder,
make sure you choose 16-bit audio rather than 12-bit from the menu.
Not only do you get higher quality, it also permits keeping the
audio track in synchronism with the video image when it comes to
editing the final. The price to pay in storing more bits is minimal.
Microphone:
to have a good audio pick-up, use an external microphone and hold
the microphone at a distance of about a foot (30cm) from the mouth;
a lapel mic is another good solution. Otherwise, the sound is
distant and we don’t hear the words clearly.
Bottom Line:
Do not re-invent the wheel. Come and see us in the Multimedia
Resource Centre. We have the equipment, software and expertise
to help you out.

Facilities and equipment available:
Our Multimedia Room (5E.1)
accommodates a teacher and a class in a controlled environment.
Digital video editing workroom : Using user-friendly
video editing software, anyone can turn their video footage into a presentation for class. Video and audio special effects are built in and titling is a snap.
- Mini-DV camcorders are available. They are ready for digital video editing on our
Macs. Editing from analog tapes is also possible. Of course, training sessions come with all of the above. Regular VHS recording format is kept for non-editing projects.

Media conversion room: This is another small workroom suitable for a small team.
- It is equipped with scanners. A flatbed scanner is used to digitize print material (photo, graphic or text). A film/slide scanner does the same for negative or positive filmand can be used to digitize the thousands of slides available around the college. They can then be used in Web pages or in PowerPoint presentations.
- We can also easily convert documents into .pdf format.
Reprovit (5E.10): Make slides from original images. The REPROVIT IIa is the best copy camera Leitz makes. It is convenient to operate; focusing is done by projecting grid onto copy -- copy lights go on automatically and lens aperture is stopped down when camera is slid into position.
Hours: We offer a Monday to Friday service from 8:30 AM to 4:00 PM. With all of the above, reservations are essential. Services are available from room 5E.5.
Finally, we want the centre to be a place where we will help you find solutions to practical needs.
For example, having problems with PowerPoint presentations? Come and
see us for practical tips. The approach will be hands-on. We will facilitate the productions but we will not do the productions for you.
In the Multimedia Resource Center we endeavour to keep up with the rapid changes in this field. As new technologies mature and others fade we will adapt our services to provide you with the best possible set of tools for your projects.
