How to avoid "Optimizing movie..." in iBooks Author?
I find the "tips" at http://support.apple.com/kb/HT5065 highly confusing.
It states that files that are already meeting the "requirements for audio and video on the iPad", will not be re-optimzied. (quote is a url-link on the support site)
Firstly, that link goes to "http://www.apple.com/ipad/", which is just iPad promo for consumers, nothing about the above promised requirements.
Secondly, when exporting from FCPX, using "Format: Apple Devices", I end up with a .m4v file - which according to the support states "You cannot use media that has .m4v or .m4p file extensions."
Thirdly, I waste my computer´s and my lifetime to sit and wait for hours of re-optimizing video...
