I created closed captioned QuickTime videos using Premiere Pro CC. I then place them in an an InDesign document and set the Media parameters to show the little captioning icon (SkinOverPlayCaption). When I export to an EPUB (Fixed Layout), Apple's iBook (Mac OS and iOS) have no trouble presenting the closed captions (**very very sweet**).
**BUT** when I export as a PDF (Interactive), I get the embedded video with a the little captioning icon on the controller, but when I play the video I can't seem to get the captions to appear (either embedded, floating window, or full screen).
My client's Section 508 compliance officer isn't very happy. Can someone help me? Please?
