Hey you're really onto something. I'm sure whatever images, text and other resources Pagetta's planning to include in the presentation, she can just print them out, and the videographer can hold each printed page in front of his lens while he plays background music into the audio port.

Developing video content in Flash isn't the ideal environment for every application, but it's a pretty robust platform for integrating video, audio, still images, text and vector graphics. And if the client then wants to repurpose the presentation for the web, it's often an easy translation.

Sure, many video production houses have their own tools to perform the same function. But it seems a condescending question to ask why Flash is "needed." If it's a tool that will get the job done, if it's a platform Pagetta's comfortable with, and if the client wants Pagetta to develop their solution, then it'd be hard to argue that the client ought to seek a different provider just to satisfy your bias for Avid, or AfterEffects, or whatever the preferred video production tool is in Alberta these days.
