Q: Why can't I upload m4v videos to iBooks Author?
I recently managed to add an m4v video to one of my books, after several days of trying, without succes, it finally worked, but without me changing anything. Now I have a new book, with a new video, (m4v) and this doesn't work as well. I get the note that one or more of the settings are not supported...
I converted the video files into m4v with Wondershare.
iBook, OS X Mountain Lion, lion

open your .mp4 or m4v in QuickTime 10
choose File > Export to > Web
in the resulting folder, use the size your need.
I have found that changing the extension to .m4a works well
hope this helps
