Hi Tosh,
Actually, I meant exactly what I said. Some things are possible with
DVD-Video that are not possible with a PowerPoint slide show and, vice
versa, some things are possible in PowerPoint slide show that are not
possible with DVD-Video. It's the nature of different formats that they
will support different capabilties and scenarios. I wasn't saying that
DVD-Video was inferior to PowerPoint slide show, just that it was different
and that, sometimes, those differences mean loss of functionality should
you attempt to recreate on DVD-Video the full set of interactivity possible
natively within a PowerPoint slide show. Having said that, those
differences might be completely acceptable to many PowerPoint customers
(once they understand what they are) given the additional benefits that
DVD-Video provides. It's just that sometimes customers only see the
benefits and don't understand the drawbacks...
Here are just a couple of examples in which DVD-Video format is not capable
providing the full PowerPoint slide show interactivity experience.
With the addition of trigger options for animation effects (PowerPoint 2002
and 2003) it is now possible to show multiple animations each of them
completely out of sequence with eachother so that each time the
presentation is delivered it can look completely different to each separate
audience depending on which triggers the presenter activates and when. This
is simply not possible with the DVD-Video format. However, If you want to
record a specific instance, of the delivery of a presentation, as a movie
(capture the specific order and timing of which triggers were activated)
then you have a perfect recording of THAT PARTICULAR DELIVERY of the
presentation. The person receiving that movie (as a DVD-Video) can no
longer change or interact with that scene of the presentation since the
interactivity has been taken away from them.
Other examples of interactivity impossible with DVD-Video include
presentations which execute code or have OLE object interaction. For
example, I don't have Excel on my DVD-Player at home so I know that if I
have specified an Action Setting to Open an Excel worksheet when I click on
it during Slide Show, I don't expect that Action Setting to work if I
convert my presentation to DVD-Video.
Also DVD-Video is lower resolution (at even it's highest quality) than the
resolution at which most computers/projectors typically used to show
PowerPoint presentations. Compound this with the fact that many television
sets are not able to display DVD-Video at it's best quality you have a
customer experience when viewing a DVD-Video of a PowerPoint presentation
on a TV that is of significantly worse visual fidelity than when the
presentation is displayed using PowerPoint on a computer display.
