The challenge lies in nominating a work process wherein my PPTs quickly evolve on a Scrivener production line. I have become quite adept at converting from PPT to RTF and managing the image files in folders generated during the process.
PowerPoint has several helpful ways of ensuring an entire presentation converts from one format to another. Results vary for me because I have different versions of the program. When I use the "Outline of the PowerPoint" view I can see all the text contents, except for words in the "Text Box". This problem goes away when I save as "Outline/RTF".
One big issue concerns whether I want to include Notes in the e-books. I have opted against that option because all my e-books link to their parent Slideshares, files I regularly update. Notes appear under shared slides when viewed through a browser.
Cross-checking new e-books to old Powerpoints is a test of editing skills. I use two mobile screens for this process, one showing the new e-book and a second holding the original slide deck. An alternative might be to send the old PPT to Microsoft Word and choosing the option of "Notes next to slides".
We are keeping time cards of each conversion process, trying to reverse-engineer the original slide-making process to ensure maximum shareability. I'd like to hear comments from early adopters, especially from those who have injected interactive elements for feedback into their first generation e-pubs.
