Animations are not supported natively in PDF files... Preview shows you just a Flash/SWF preview, not PDF preview.
Only way to use animations in PDF files is to create Flash/SWF file which includes animation(s), place that SWF to InDesign and export Interactive PDF after that.
And it´s just a work-around, not very good one IMO.... I don´t believe you can do animated menus with that technique....
Animations CANNOT be exported to an interactive PDF. There is no support for animations in PDF.
The Preview feature is actually a SWF (Flash) preview, and only accurately shows previews of what would be exported into a SWF file, not a PDF file.
Ok perfect, that's what I was missing it looks like. I looked around on the web and couldn't figure out what I was missing. I will go that route then! Thanks so much for the explanation!
Thanks Steve, it looks like you guys found my issue, thanks for that!
