It is currently impossible, I'm told by TechSmith support, to export PPT slides back out of Camtasia. Scenario: import slides as media, record audio, edit audio, change or delete a slide during the course of the editing. With no way to resave those slides, you no longer have a canonical set for other purposes. It's puzzling that this isn't possible now--the media are still there, just need to back them back out. The only apparent solution is to screenshot each slide in the recording, save as an image and then create a new slide deck from the pasted images--so they are no longer editable.
