Making a CD / DVD |
The
production of CD and DVD's can enhance the
interactivity offered by straight video production. The amount
of interactivity varies between the two with DVD offering
simple interface based access to sections of the video.
The video encoding for DVD is a higher resolution
than that
offered on CD. CD on the other hand can be used to
incorporate text, still pictures, video and audio to offer the audience true
multi-media which is ideal for training and
education materials.
The way in which humans learn and take in information
differs, some learn in blocks of information and some with
pictures with many aspects inbetween for example:
- An imager finds pictures easier than words
therefore learns best from visual displays.
- A verbaliser finds speech and text easier than diagrams and learns
best from visual presentation.
- A wholist finds difficulty in disembodying but is able to see the whole
story.
- An analytic finds difficulty in seeing the whole and analyses material
into its parts.
In essence the more senses that are stimulated, the better the message and the more likely it is to coincide with an individuals learning style.
Format choice
When deciding which format to use for disseminating training materials
it is important to look closely at the target audience and the technology
available for them to use the materials. So if it is a sales video where
all the sales team in a large company have access to similar computers
with a similar specification then DVD R may be the best solution.
DVD Rom or DVD-R
As with most new systems there are some compatibility problems when using
DVD R disks in different DVD players. Thus if a DVD is going to be for
general release it is probably best to burn it onto DVD Rom as there
will be less compatibility problems with this format. If however the
DVD is targeted at an audience where the specification of their DVD machine
is known then DVD R is probably best. This might be when the DVD is going
to be used by a sales force for a large company where the specification
of the computer and DVD playing software is known.
CD R
With CD R's there are less problems than with DVD and most modern multi-media
computers are likely to be able the play a CD R. However there are occasional
exceptions to this for instance when there is a problem with a graphics
or sound card, or perhaps the computer does not have any of these fitted.
Sometimes to work a CD may require a particular piece of software such
as "Flash" it is important the user is given the opportunity
to download this if required. Generally there are few problems with this
format.
