Hmmm, thanks for the heads up. I need to go do some googling now to find out more about whatever this "scaffolding" thing is all about.
I'm guessing a logical first stop would be to check out this screencast-o-matic thing and see how it operates.
But that does make me wonder. If screencast-o-matic is all that and a bag 'o chips better, why not use it to create the videos, then just add them to Captivate? Because you want your entire workflow in one product?

Scaffolding is a instructional concept in education. This is a pretty good explanation (even just the first paragraph): http://edglossary.org/scaffolding/
Scaffolding of process (and providing limitation or restrictions) can be a good way to ensure a higher quality end product. If you use a program like Adobe Voice it had in built process scaffolding and restrictions. You pick a structure first (which makes suggestions about what each slide should cover), and then you record audio (never longer than ten seconds at once), and then you adjust your layout, and then you pick icons or images or text, and then you sort your music, and then you review, and then you export (and on export you adjust credits and titles). It's a truncated version of the filmmaking process that guides you towards making a better product. That's (one of the reasons) why voice projects come out much nicer and profession than you could do on other software. You could make the same stuff with PowerPoint but you'd be using copious workarounds to get your content in and PowerPoint doesn't provide you with that scaffolding so even the most talented producers still struggle to produce anything better than a typical Voice project.
I'm not that fussed about it all being in one product. I've been using adobe products for over 15 years now - I'm used to switching between programs that suit different tasks. The real reason I can't use both is that my work won't pay for two software packages that have similar outcomes. If Captivate could do what screencast-o-matic can do (without the workarounds) it'd be a simple choice to go with Captivate. It wouldn't even have to be in the Captivate program - it could be in a sister program made available with the Captivate package. The same way After Effects and Premiere compliment each other.
For now it seems Captivate has more functions but a lesser embedded process which means we'll likely just stick with Screencast-O-Matic.
What I really want is for Adobe to take the understanding of education and instruction theories they've applied to Voice and Slate and apply that to Captivate (or a program that is packaged in with a Captivate purchase). I think it's weird that they haven't yet...
